Title: Myofascial release tool

Description:
BACKGROUND 
     Myofascial release techniques find applicability in many fields, including massage therapy, physical therapy, and chiropractic care, for example to correct or improve the health of multiple body parts and tissues such as muscles and fascia. When muscles are sore or damaged, they may contract. Contracted muscles may lead to immobility and pain in the area of the contracted muscle. Fascia is a connective tissue that covers muscles. Fascia can become restrictive from, for example, overuse, trauma, and inflammation, which may lead to adhesion formation, further muscle spasm, and decreased blood flow to the corresponding muscle. Myofascial release techniques generally focus on relaxing contracted muscles and restricted fascia by stimulating proprioceptors and mechanoreceptors in the muscle of interest. Conventionally, myofascial release techniques include a therapist or chiropractor repeatedly pressing or “kneading” a muscle of interest until release is achieved. However, these techniques are laborious for the health care provider, often result in painful therapy for the patient, and allow the patient&#39;s reflexes to work against the health care provider, leading at times to less than favorable therapeutic results.

     DETAILED DESCRIPTION 
     Overview 
     This overview, including section titles, is provided to introduce a selection of concepts in a simplified form that are further described below. The overview is provided for the reader&#39;s convenience and is not intended to limit the scope of the implementations or claims, nor the proceeding sections. 
     This disclosure describes myofascial release tools and methods of using the same. 
     As discussed above, myofascial release techniques are laborious for the treating health care provider, often result in painful therapy for the patient, and allow the patient&#39;s reflexes to work against the health care provider, leading to less than favorable therapeutic results. Example myofascial release tools and methods of using the same as described herein allow for myofascial release therapy and muscle tension reduction therapy that is easier and quicker to perform by a health care professional, results in decreased pain to the patient, and hinders the ability of the patient&#39;s reflexes to work against the health care provider. Additionally, the myofascial release tools and methods described herein provide treatment for a wider range of body tissues and parts than could be achieved through conventional myofascial release techniques, diversifying myofascial release applicability. The tools described herein alleviate the shortcomings of current myofascial release techniques by utilizing one or more tips that may be composed at least partially of thermoplastic elastomer with molecular bonding capabilities made from, at least in part, amorphous thermoplastic pellets designed as described below. Each of the one or more tips may be received in an oscillating device, such as a reciprocating saw, and the health care professional may engage the oscillating device to repeatedly contact a desired location of the patient&#39;s body. The design of the one or more tips accompanied by the repeated oscillation against the patient&#39;s body may provide effective myofascial release in a reduced amount of treatment time. 
     In an example, a myofascial release tool may comprise a post that may have a distal end and a proximal end. The proximal end may be sized to be received by an oscillating device. The myofascial release tool may also comprise a head, which may be constructed at least partially of a polymeric material. The polymeric material may cover at least a portion of the distal end of the post and may be coupled to the post. The head may have a durometer sufficient to provide a therapeutic effect to a desired location of the patient&#39;s body. The durometer may vary depending on the location of treatment, therapeutic effect, or clinical application desired by the health care provider. 
     In an example, a myofascial release tool may comprise a tip that may include a post and a head coupled to a first end of the post. The head may be constructed at least partially of a polymeric material having a durometer sufficient to provide a therapeutic effect to a desired location of the patient&#39;s body. The myofascial release tool may also comprise an oscillating device configured to receive a second end of the post. 
     In an example, a myofascial release apparatus may comprise a plurality of tips. Each tip of the plurality of tips may have a proximal end sized to be received at least partially in an oscillating device. The plurality of tips may also be interchangeable and may be constructed at least partially of a polymeric material. The plurality of tips may be designed to have differing structures and/or designs to provide varying therapeutic effects to varying areas of the patient&#39;s body. 
     In an example, a method of using myofascial release tools may comprise oscillating at least one of the plurality of tips on a desired portion of the patient&#39;s body. The oscillating may be accomplished by operation of an oscillating device with a tip received by the oscillating device. A health care provider may choose a tip from the plurality of tips that is designed for use on a specific portion of the patient&#39;s body and/or for treatment of specific tissue (e.g., muscle, tendon, ligament, bone, fascia, etc.). The health care provider may connect the chosen tip to the oscillating device. The health care provider may contact the tip with the body of the patient and enable the oscillating device to begin oscillation. The health care provider may exert a certain amount of force during oscillation depending on the chosen tip and desired therapeutic effect. The health care provider may change tips during a treatment session to treat additional areas of the body and/or additional tissues. The tips may comprise varying durometers and designs and be interchangeable without substantial effort or time. 
     Myofascial release tools according to this disclosure may be designed for a variety of applications, such as, for example, physical therapy, massage therapy, chiropractic care, or for use by a patient without aid from a health care provider. The myofascial release tools according to this disclosure may be used on various parts of the body, including, for example, skeletal muscles, fascia, tendons, ligaments, and the connections between bone and any other connective tissue. 
     One or more examples of the present disclosure are illustrated in the accompanying drawings. Those of ordinary skill in the art will understand that the tools and methods specifically described herein and illustrated in the accompanying drawings are non-limiting examples and that the scope of these examples is defined solely by the claims. The features illustrated or described in connection with one example may be combined with the features of other examples. For example, design elements described with respect to one example may be incorporated, in whole or in part, into the design elements of another example. Such modifications and variations are intended to be included within the scope of the appended claims. 
     Additional details are described below with reference to several examples. 
     Example Devices 
       FIGS. 1-7  illustrate various examples of myofascial release tools. Unless otherwise expressly stated, the sizes, shapes, and symbols used to describe the various components of the tools are used for illustration only and should not be used as limitations of the tools as described herein. 
       FIG. 1  is a perspective view of an example of a myofascial release tool  100 . The tool  100  may include a post  102 . The post  102  may have a distal end  104  and a proximal end  106 . The proximal end  106  may be sized to be received by an oscillating device. In an example, the oscillating device may be any device that provides oscillating motion, such as, for example, a reciprocating saw, an oscillating saw, or sabre saw. The oscillating device may enable oscillation of a tip in a substantially linear motion from, for example, approximately 1 revolution per minute (RPM) to approximately 3,000 RPM. In other examples, the oscillation of the tip may be in a circular motion or a random motion. In still other examples, the oscillation of the tip may be in a sweeping motion, such that the oscillation causes the tip to move back and forth in a direction tangential to the oscillating device. In other examples, as used herein, RPM may be alternatively defined as strokes per minute. In an example, the oscillating device may oscillate at more than 3,000 RPM. For example, the oscillating device may oscillate at at least 3,000 RPM, at least 3,500 RPM, at least 4,000 RPM, at least 4,500 RPM, at least 5,000 RPM, or more. The post  102  may be tooled to include grooves, indents, and other configurations to allow the proximal end  106  to be received within a particular oscillating device. The post  102  may be tooled such that, when received by the oscillating device, the post  102  lockedly couples with the oscillating device. Coupling of the post  102  to the oscillating device may be desired during use of tool  100  as described more fully herein. The post  102  may be uncoupled from the oscillating device to allow for storage or for additional tools  100  to be used. In an example, the oscillating tool may be a tool sold in home improvement stores, without modification. In an example, the oscillating tool may be modified to provide, for example, a reconfigured connection mechanism to receive the post  102 , increased control over RPMs, a reconfigured handle, or other components that allow for easier treatment of a patient. 
     The tool  100  may also comprise a head  108 . The head  108  may be constructed at least partially of a polymeric material. The head  108  may cover at least a portion of the distal end  104  of the post  102 . The head  108  may also be coupled to the post  102 . In an example, the head  108  may be releasably coupled to the post  102 , which may allow a user to remove the head  108  from the post  102 . In an example, the polymeric material may include, but is not limited to, amorphous thermoplastic pellets and/or thermoplastic elastomers. The head  108  and post  102  may be two separate components that are coupled together, or the head  108  and the post  102  may comprise a single component. The head  108  and post  102 , whether constructed as separate components or a single component, may otherwise be described as a tip. 
     The head  108  may have a durometer sufficient to provide therapeutic treatment to a patient. The specific durometer of head  108  may vary depending on the desired bodily area of treatment, the desired tissue to be treated, and a host of other factors including but not limited to the physical condition of the patient, patient age, patent pain tolerance, past medical history of the patient, and previous efficacy of myofascial release treatments. In an example, the durometer may be between approximately 10 A and approximately 50 A. As used herein, durometer is measured based on the Shore Hardness Scale. For example, the Shore A scale is used to define the durometer in this disclosure. However, it should be understood that other units of measuring hardness are not excluded from this disclosure. For example, a Shore A durometer of 10 A may equate to a roughly 55 durometer on the Shore 00 scale. Likewise, a Shore A durometer of 70 A may equate to a roughly 14D durometer on the Shore D scale. Other units of hardness may also be used. 
     In an example, the durometer of the head  108  may be at least 5 A, at least 10 A, at least 20 A, at least 30 A, at least 40 A, at least 50 A, at least 60 A, or at least 70 A. In an example, the durometer of the head  108  may be less than 70 A, less than 60 A, less than 50 A, less than 40 A, less than 30 A, less than 20 A, less than 10 A, or less than 5 A. In an example, the durometer of the head  108  may be between approximately 10 A and approximately 50 A, or between approximately 15 A and approximately 40 A, or between approximately 10 A and approximately 20 A, or between approximately 20 A and approximately 30 A, or between approximately 30 A and approximately 40 A, or between approximately 40 A and approximately 50 A, or between approximately 50 A and approximately 60 A, or between approximately 60 A and approximately 70 A. 
     Treatment of a certain body part, a certain tissue type, or a certain patient may influence the durometer. By way of example, during treatment of a large muscle, such as a pectoral muscle, quadriceps, or hamstrings, or during treatment of a patient with a more athletic build, a higher durometer may be optimal to provide increased impact to the muscle during treatment. In this example, the durometer of the head  108  may be, for example, approximately 40 A or greater. In other examples, such as during treatment of smaller muscle groups, or for use on soft tissue, or for use on a patient with average muscle tone and having average health, the head  108  may have a durometer of, for example, approximately 30 A. In still other examples, such as during treatment of skeletal tissues, or certain tendons or ligaments, or for use on a fragile patient, the head  108  may have a durometer of, for example approximately 20 A or less. 
     The head  108  may also comprise a variety of designs or configurations. For example, the head  108  may include a first portion  110  that may be substantially cylindrical in shape. The length and diameter of the first portion  110  may vary given a desired treatment application of the head  108 . In an example, the first portion  110  may be approximately two inches in length and approximately an inch and a half in diameter. In further examples, the first portion  110  may be between 0.1 inches and 0.5 inches in length, between 0.5 inches and 1.0 inches in length, between 1.0 inches and 1.5 inches in length, between 1.5 inches and 2.0 inches in length, between 2.0 inches and 3.0 inches in length, or more than 3.0 inches in length. In further examples, the first portion  110  may be between 0.1 inches and 0.5 inches in diameter, between 0.5 inches and 1.0 inches in diameter, between 1.0 inches and 1.5 inches in diameter, between 1.5 inches and 2.0 inches in diameter, between 2.0 inches and 3.0 inches in diameter, or more than 3.0 inches in diameter. In should be noted that the dimensions of the first portion  110  may be measured in terms of radius instead of or in addition to diameter. Additionally, while the units of measurement used herein include inches, those units of measurement are not exclusive. To the contrary, the metric equivalent of these measures is also included. Specifically, the first portion  110  may be measured in terms of centimeters, is some examples. The head  108  may also comprise a second portion  112  that may be at least partially concave such that an indent  114  may be defined on the second portion  112  of the head  108 . In an example, the indent  114  may have a depth gradient such that the indent  114  may be more pronounced on one side of the second portion  112  and less pronounced on another side of the second portion  112 . In an example, the indent  114  may be substantially uniform in depth across the second portion  112  of the head  108 . 
     The configuration of the second portion  112  may resemble a groove with side walls (labeled as  116   a  and  116   b ). The side walls of the second portion  112  may surround the entire indent  114 , or the side walls may surround only a portion of the indent  114  such that the indent  114  resembles a channel. By way of example, the configuration of the head  108  as shown in  FIG. 1  may be used on narrow or small portions of the patient&#39;s body, such as the iliotibial band, forearm muscles, calf muscles, trapezius, triceps, and biceps, for example. In use, the oscillated device may receive the tool  100  and the health care provider may enable the oscillating device such that the tool  100  oscillates. The health care provider may place the tool  100  over the desired portion of the patient&#39;s body such that all or a portion of the desired portion rests in the indent  114  and is straddled by the side walls of the second portion  112 . This configuration of the tool  100  may allow the health care provider to move the tool  100  up and down a muscle while keeping the tool  100  from vibrating off of the body part of interest. 
     The configuration of the second portion  112  may also resemble a double groove. In examples, one groove of the double groove may be situated toward the center of the second portion  112  and be narrower than a second groove. In these examples, the one groove may appear to be a groove within the second groove. When in use, the one groove may be used on narrow or small portions of the patient&#39;s body, while the second, wider groove may be used on wider portions of the patient&#39;s body. 
       FIG. 2  illustrates a cross-sectional side view of an example myofascial release tool  200 . The cross-section shown in  FIG. 2  is made at or near the center of tool  200  such that the head and post are essentially split in half. Tool  200  may comprise the same or similar components as tool  100 . For example, tool  200  may include a post  202  having a distal end  204  and a proximal end  206 , and a head  208  having a first portion  210  and a second portion  212 . Tool  200  may also include a core  214 . Core  214  may comprise a component separate from the post  202 , or the core  214  may comprise a portion of the post  202  that is coupled to the head  208 . The core  214  may be shaped to secure the head  208  to the core  214 , such as, for example, by one or more grooves that prohibit or hinder separation of the core  214  from the head  208 . In an example, the core  214  may have locking and unlocking capabilities such that, when locked, the core  214  is prohibited or hindered from disengaging from the head  208 , and when unlocked, a user may disengage the core  214  from the head  208 . 
     When the core  214  is a separate component from the post  202 , the core  214  may be secured to the post  202  through multiple attachment means, such as for example, tongue-in-groove designs, rivets, adhesive, threads, screws, and/or by a ball bearing system. In an example, using threaded attachment means, the core  214  may be screwed on and off the post  202 . In another example, using a ball bearing attachment means, the core  214  may lockedly engage the post  202  when the ball bearings are engaged. An operator may exert opposing forces on the ball bearing system to disengage the ball bearings and allow the core  214  to be removed from the post  202 . The shape of the core  214  may vary with, for example, the shape and design of the head  208 . As described above with respect to  FIG. 1 , the head  208  may have a variety of designs and shapes. The core  214  may have a substantially similar design and/or shape to a given head  208 , or the shape of the core  214  may be independent of the shape of a given head  208 . In examples where the post  202  and the head  208  are a single component, the core  214  may be absent or may define a portion of the head  208 . 
     In examples, the head  208  may be configured as a cover that engages with the core  214 . The head  208  may slip on to, or otherwise be sized to fit snugly on the core  214 . In examples, the core  214  may be made of at least a partially polymeric material with a durometer that is similar to that of the head  208 . In an example, the core  214  may have a durometer that is greater than that of the head  208 . The core  214  may also be constructed at least partially of a sponge material, metal, and/or stone. 
       FIG. 3  illustrates a side view of an example myofascial release tool  300 . Tool  300  may comprise the same or similar components as tool  100 . For example, tool  300  may comprise a post  302  having a distal end  304  and a proximal end  306 , and a head  308  having a first portion  310  and a second portion  312 . Tool  300  may also comprise a design that differs from tool  100 . For example, the first portion  310  of head  308  may be substantially cylindrical, while the second portion  312  of head  308  may be angled such that one side of the second portion  312  is higher than another side of the second portion  312 . The length and diameter of the first portion  310  may vary given a desired treatment application of the head  308 . In an example, the first portion  310  may be approximately two inches in length and approximately an inch and a half in diameter. In further examples, the first portion  310  may be between 0.1 inches and 0.5 inches in length, between 0.5 inches and 1.0 inches in length, between 1.0 inches and 1.5 inches in length, between 1.5 inches and 2.0 inches in length, between 2.0 inches and 3.0 inches in length, or more than 3.0 inches in length. In further examples, the first portion  310  may be between 0.1 inches and 0.5 inches in diameter, between 0.5 inches and 1.0 inches in diameter, between 1.0 inches and 1.5 inches in diameter, between 1.5 inches and 2.0 inches in diameter, between 2.0 inches and 3.0 inches in diameter, or more than 3.0 inches in diameter. In should be noted that the dimensions of the first portion  310  may be measured in terms of radius instead of or in addition to diameter. Additionally, while the units of measurement used herein include inches, those units of measurement are not exclusive. To the contrary, the metric equivalent of these measures is also included. Specifically, the first portion  310  may be measured in terms of centimeters, is some examples. 
     In an example, the second portion  312  may resemble a pointed or substantially pointed end. Tool  300  may be used, for example, for myofascial release on an area of the body that requires more focused pressure than tool  100 , wherein the substantially pointed end of the second portion  312  contacts the patient. Tool  300  may be used, for example, on portions of a patient&#39;s neck, on or around a patient&#39;s clavicle, and on areas where muscle connects to bone. The diameter of tool  300  may be the same as the diameter of tool  100 , or tool  300  may have a different diameter. In an example, tool  300  has a smaller diameter to allow for further pinpointed pressure to be applied to the patient. In an example, the design of the second portion  312  creates a sloped end of the head  308 . 
     A health care provider may use tool  300  by contacting the patient with the sloped portion of the head  308  instead of, or in addition to, the substantially pointed portion. By treating a patient with the sloped portion of the head  308 , pressure created during treatment may be partially deflected away from the area of treatment. The health care provider may adjust the angle at which the head  308  contacts the patient to increase or decrease contact with the sloped portion of the head  308 . This design may allow for in-treatment control and adjustment of myofascial release pressure in response to patient feedback and reaction. 
     The angle of the second portion  312  of the head  308  may vary. In an example, the angle may be only slightly greater than 0° to allow for a flatter surface to apply to a patient. In other examples, the angle may be any angle between approximately 0° and approximately 90°, such as, for example, between 0° and 15°, between 15° and 30°, between 30° and 45°, between 45° and 60°, between 60° and 75°, or between 75° and 90°, which may allow for a more pointed surface to apply to a patient. In an example, the angle of the second portion  312  may be approximately 45°. In this example, the substantially pointed portion created by the angled design may be used to contact the patient, and/or the sloped portion may be used during the same treatment session, for example. The substantially pointed portion may have a substantially straight edge or may be slightly rounded. 
       FIG. 4  illustrates a side view of an example myofascial release tool  400 . Tool  400  may include the same or similar components as tool  100 . For example, tool  400  may comprise a post  402  having a distal end  404  and a proximal end  406 , and a head  408 . Tool  400  may comprise a design that differs in some respects from the design of tool  100  and/or tool  300 . For example, the head  408  of tool  400  may comprise a first end  410  that is at least partially convex. In an example, the second end  412  may be substantially cylindrical. The length and diameter of the second end  412  may vary given a desired treatment application of the head  408 . In an example, the second end  412  may be approximately two inches in length and approximately an inch and a half in diameter. In further examples, the second end  412  may be between 0.1 inches and 0.5 inches in length, between 0.5 inches and 1.0 inches in length, between 1.0 inches and 1.5 inches in length, between 1.5 inches and 2.0 inches in length, between 2.0 inches and 3.0 inches in length, or more than 3.0 inches in length. In further examples, the second end  412  may be between 0.1 inches and 0.5 inches in diameter, between 0.5 inches and 1.0 inches in diameter, between 1.0 inches and 1.5 inches in diameter, between 1.5 inches and 2.0 inches in diameter, between 2.0 inches and 3.0 inches in diameter, or more than 3.0 inches in diameter. In an example, the second end  412  may have a partially conical shape such that the end of the head  408  nearest the post  402  has a smaller diameter than the end of the head opposing the post  402 . The difference between the diameters on either end of the head  408  may vary given a desired application of the head  408 . In should be noted that the dimensions of the second end  412  may be measured in terms of radius instead of or in addition to diameter. Additionally, while the units of measurement used herein include inches, those units of measurement are not exclusive. To the contrary, the metric equivalent of these measures is also included. Specifically, the second end  412  may be measured in terms of centimeters, is some examples. 
     For example, when treatment of a thicker muscle group or an athletically-built patient is desired, the difference between the diameters may be negligible or slight. This may provide a head  408  with additional weight and durability, which in turn may provide the health care provider with the ability to increase pressure of tool  400  during treatment. In an example, such as when treating thinner muscle groups, the diameter of the head  408  nearest the post  402  may be, sometimes substantially, smaller than the diameter of the head  408  on the end opposing the post  402 . This may provide a head  408  with less weight, which may be desired when the surface area of treatment is comparatively large but increased pressure is not desired, such as when treating a less athletically-built patient. 
     The degree of protuberance of the convex-shaped first end  410  may also vary. In an example, the degree of protuberance may be slight, such that the surface of the head  408  that contacts the patient is only slightly convex. In other examples, the degree of protuberance may more pronounced, such that the surface of the head  408  that contacts the patient is appreciably convex, which may resemble a more rounded surface. 
     The overall size of the head  408  may be similar to the head sizes of tool  100  and/or tool  300 , or the size of the head  408  may vary from tool  100  and/or tool  300 . For example, the head  408  may be larger than head  108  or head  308  in one or more respects. The head  408  may have an overall diameter of more than 1 inch, more than 1.5 inches, more than 2 inches, more than 2.5 inches, more than 3 inches, more than 3.5 inches, more than 4 inches, more than 4.5 inches, or more than 5 inches. Additionally, the length of the head  408  may be more than 1 inch, more than 1.5 inches, more than 2 inches, more than 2.5 inches, more than 3 inches, more than 3.5 inches, or more than 4 inches. Furthermore, the curvature of the convex first end  410  may vary by the inverse length of the radius of the first end  410 . In should be noted that the dimensions of the head  408  may be measured in terms of radius instead of or in addition to diameter. Additionally, while the units of measurement used herein include inches, those units of measurement are not exclusive. To the contrary, the metric equivalent of these measures is also included. Specifically, the head  408  may be measured in terms of centimeters, is some examples. 
       FIG. 5  illustrates a side view of an example myofascial release apparatus  500 . Apparatus  500  may comprise the same or similar components as tool  100 . For example, apparatus  500  may comprise a post  502  having a distal end  504  and a proximal end  506 , and a head  508 . Apparatus  500  may also comprise an oscillating device  510 , and the post  502  and head  508  may collectively represent a tip  512 . As shown in  FIG. 5 , the proximal end  506  of the post  502  may be sized to be received by the oscillating device  510 . The proximal end  506  of the post  502  may contain grooves and/or slots configured to allow the post  502  to fit into a common oscillating device such as, for example, a reciprocating device. In other examples, the receptacle portion of the oscillating device  510  may be configured to specifically receive post  502  as described herein. 
     In an example, the oscillating device  510  may oscillate the post  502  in a substantially linear motion from, for example, approximately 1 RPM to approximately 3,000 RPM. In other examples, the RPM may be alternatively defined as strokes per minute. In an example, the oscillating device  510  may oscillate at more than 3,000 RPM. For example, the oscillating device may oscillate at at least 3,000 RPM, at least 3,500 RPM, at least 4,000 RPM, at least 4,500 RPM, at least 5,000 RPM, or more. The post  502  may be tooled to include grooves, indents, and other configurations to allow the proximal end  506  to be received within the oscillating device  510 . The post  502  may be tooled such that, when received by the oscillating device  510 , the post  502  lockedly couples with the oscillating device  510 . Coupling of the post  502  to the oscillating device  510  may be desired during use of apparatus  500  as described more fully herein. The post  502  may be uncoupled from the oscillating device  510  to allow for storage or for additional tips  512  to be used. In an example, the oscillating tool  510  may be a tool sold in home improvement stores, without modification. In other examples, the oscillating tool  510  may be modified to provide, for example, a reconfigured connection mechanism to receive the post  502 , increased control over RPMs, a reconfigured handle, or other components that allow for easier treatment of a patient. 
     Apparatus  500  may be used in connection with a variety of tips  512 , such as, for example, tool  100 , tool  200 , tool  300 , and/or tool  400 . The tips  512  may be interchangeable, such that, for example, tool  100  can be initially received in the oscillating device  510  and can be removed and replaced with, for example, tool  200 , which could be removed and replaced with, for example, tool  300 , which could be removed and replaced with, for example, tool  400 . 
     The tips  512  may also be rotatable about the post  502 , such that the tip  512  and/or the post  502  and/or the head  508  may rotate. In an example, the tips  512  may be freely rotatable by providing a turning force in the desired direction of rotation. A certain threshold of force may be required to rotate the tips  512 . In an example, the tips  512  may include one or more notches that may allow the tips  512  to snap into differing rotatable positions when received by the oscillating device  510 . In an example, the tips  512  may include one or more ball bearing assemblies that may allow the tips  512  to rotate when the ball bearings are disengaged, but may not allow the tips  512  to rotate when the ball bearings are engaged. During a treatment session, the health care provider may rotate the tip  512  received by the oscillating device  510  to promote treatment of a given area of the body. 
     For example, using tool  300 , which includes an angled head design, the health care provider may adjust the tip  512  such that the substantially pointed end is on the left side of the tip  512  when viewed from behind the oscillating device  510  from the perspective of the health care provider. The health care provider may start treatment on a given area on the left side of the patient&#39;s body, such as, for example, the left side of the patient&#39;s neck. The health care provider may then desire to treatment the right side of the patient&#39;s neck and may rotate the tip  512  such that the substantially pointed end is on the right side of the tip when viewed from behind the oscillating device  510  from the perspective of the health care provider. This may allow the health care provider to treat the right side of the patient&#39;s neck in the same manner as treatment on the left side of the neck. Treatment of other areas of the body not provided by way of example may also benefit from the rotatably of the tips  512 . 
     In an example, the tips  512  may have a portion with a first durometer and another portion with a second durometer. For example, the portion of the tip  512  that is nearest the oscillating device  510 , when received therein, may have a greater durometer than a portion of the tip that is opposing the oscillating device  510 . For example, with reference to tool  100 , the first portion  110  of the head  108  may have a first durometer such as, for example, of 50 A. The second portion  112  of the head  108  may have a second durometer such as, for example, of 30 A. The head  108  in these examples have provide a more durable base for the head  108  and allow the head  108  to more securely couple to the post  102  while also providing a softer portion that contacts the patient. The differences in durometer may be present as between different sections of the tip  512 , or tip  512  may have a gradient of differing durometers. 
       FIG. 6  illustrates a plurality of tips of an example myofascial release apparatus  600 . Apparatus  600  may comprise a plurality of tips  602  (labeled  602   a ,  602   b , and  602   c ). The plurality of tips may include 2 tips, 3 tips, or more tips. Each tip of the plurality of tips may be uniform in size, shape, or design, or a tip of the plurality of tips may differ in size, shape, or design from any or all of the other tips of the plurality of tips. In an example, the plurality of tips may comprise the designs of tool  100 , tool  200 , tool  300 , and/or tool  400 . In an embodiment, the plurality of tips  602  may comprise the same or similar features, and be constructed of similar materials as tool  100 , tool  200 , tool  300 , and/or tool  400 . The plurality of tips  602  may be interchangeable, as described above, and the plurality of tips  602  may be rotatable, also as described above. For example, tool  500  may comprise a post  502  having a distal end  504  and a proximal end  506 , and a head  508 . Tool  500  may also be constructed of the same or similar materials as tool  100 , tool  200 , tool  300 , and/or tool  400 . 
       FIG. 7  illustrates a side view of an example myofascial release tool  700 . Tool  700  may comprise the same or similar components as tool  100 . For example, tool  700  may comprise a post  702  having a distal end  704  and a proximal end  706 , and a head  708  having a first portion  710  and a second portion  712 . Tool  700  may also comprise a design that differs from tool  100 . For example, the first portion  410  may have a partially conical shape such that the end of the head  708  nearest the post  702  has a smaller diameter than the end of the head  708  opposing the post  702 . The difference between the diameters on either end of the head  708  may vary given a desired application of the head  708 . In should be noted that the dimensions of the first portion  410  may be measured in terms of radius instead of or in addition to diameter. 
     The second portion  712  of the head  708  may have various indents  714 . In examples, the design of tool  700  may have a double indent  714 , wherein the indent  714  has a portion that is wider than another portion, as shown in  FIG. 7 . Tool  700  may allow a practitioner to situate a portion of a patient&#39;s body in the indent and provide myofascial release as described herein. Certain portions of the patient&#39;s body may be larger, and as such, may fit at least partially within the wider portion of the indent  714 . Certain other portions of the patient&#39;s body may be smaller or thinner, and as such, may fit at least partially within the narrower portion of the indent  714 . This double indent design may allow a practitioner to provide myofascial release to various parts of a patient&#39;s body without interrupting treatment to change tips. 
     As described in  FIGS. 1-7 , various components of tools  100 - 400  and  700 , and apparatuses  500 - 600 , have been described as components of certain examples of the myofascial release tools and apparatuses described herein. However, it should be understood that in some examples each component described herein may be included in any or all of tools  100 - 400  and  700 , and apparatuses  500 - 600 , and the inclusion of a component in one example does not exclude its potential inclusion in other examples. Additionally, multiples of the components of tools  100 - 400  and  700 , and apparatuses  500 - 600 , may also be included. 
     The tools and apparatuses described in  FIGS. 1-7  may alleviate some or all of the shortcomings of current myofascial release techniques by decreasing physical effort required by a health care professional, decreasing pain to the patient, and hindering the ability of the patient&#39;s reflexes to work against the health care provider. Additionally, the myofascial release tools and methods described herein provide treatment for a wider range of body tissues and parts than could be achieved through conventional myofascial release techniques, diversifying myofascial release applicability. 
     Example Methods 
     Also disclosed herein are methods of using a myofascial release tool, such as those described herein.  FIG. 8  illustrates an example method of operating a myofascial release tool, such as described herein. Method  800  is illustrated as a logical flow graph. The order in which the operations or steps are described is not intended to be construed as a limitation, and any number of the described operations can be omitted, modified, or combined in any order and/or in parallel to implement method  800 . 
     In an example, a method of using myofascial release tools may include oscillating at least one of a plurality of potential tips on a desired portion of a patient&#39;s body. The oscillating may be accomplished by operation of an oscillating device with a tip received by the oscillating device. 
     At block  802 , method  800  may include choosing a tip from the plurality of tips that is designed for or otherwise could be used on a specific portion of the patient&#39;s body and/or for treatment of specific tissue (e.g., muscle, tendon, ligament, etc.). 
     At block  804 , method  800  may include connecting the chosen tip to the oscillating device. The tips chosen by the health care provider may comprise a variety of designs and configurations. For example, the tip may comprise a first portion that may be substantially cylindrical in shape and a second portion that may be at least partially concave such that an indent may be defined on the second portion of the tip. In an example, the indent may have a depth gradient such that the indent may be more pronounced on one side of the second portion and less pronounced on another side of the second portion. In other examples, the indent may be substantially uniform in depth across the second portion of the tip. This tip may be used on narrow or small portions of the patient&#39;s body, such as the iliotibial band, forearm muscles, calf muscles, trapezius, triceps, and biceps, for example. 
     The design of the tip may also, or alternatively, comprise a first portion that may be substantially cylindrical, while a second portion may be angled such that one side of the second portion is higher than another side of the second portion. The tip described in this example may be used, for example, for myofascial release on an area of the body that requires more focused pressure than other tips, wherein the substantially pointed end of the second portion contacts the patient. This tip may be used, for example, on portions of a patient&#39;s neck, on or around a patient&#39;s clavicle, and on areas where muscle connects to bone. This design may allow for in-treatment control and adjustment of myofascial release pressure in response to patient feedback and reaction. 
     The design of the tip may also, or alternatively, comprise a first end that is at least partially convex. In an example, the second end may be substantially cylindrical. The second end may have a partially conical shape such that the end of the tip nearest the oscillating device has a smaller diameter than the end of the tip opposing the oscillating device. The difference between the diameters on either end of the tip may vary given a desired application. For example, when treatment of a thicker muscle group or an athletically-built patient is desired, the difference between the diameters may be negligible or slight. This may provide a tip with additional weight and durability, which in turn may provide the health care provider with the ability to increase pressure of during treatment. In other examples, such as when treating thinner muscle groups, the diameter of the tip nearest the oscillating device may be, sometimes substantially, smaller than the diameter of the tip on the end opposing the oscillating device. This may provide a tip with less weight, which may be desired when the surface area of treatment is comparatively large but increased pressure is not desired, such as when treating a less athletically-built patient. The degree of protuberance of the convex-shaped first end may also vary. In an example, the degree of protuberance may be slight, such that the surface of the tip that contacts the patient is only slightly convex. In other examples, the degree of protuberance may more pronounced, such that the surface of the tip that contacts the patient is appreciably convex, which may resemble a more rounded surface. 
     At block  806 , method  800  may include contacting the tip to the body of the patient. The health care provider may place the tip over the desired portion of the patient&#39;s body such that all or a portion of the desired body part rests in the indent, in an example, and is straddled by the side walls of the second portion. This configuration of the tip may allow the health care provider to move the tip up and down a muscle while keeping the tip from vibrating off of the body part of interest. 
     A health care provider may use the angled tip, described above, by contacting the patient with the sloped portion instead of, or in addition to, the substantially pointed portion. By treating a patient with the sloped portion, pressure created during treatment may be partially deflected away from the area of treatment. The health care provider may adjust the angle at which the tip contacts the patient to increase or decrease contact with the sloped portion. 
     At block  808 , method  800  may include enabling the oscillating device such that oscillation of the tip occurs. 
     At block  810 , method  800  may include exerting a certain amount of force during oscillation depending on the chosen tip and desired therapeutic effect. The health care provider may change tips during a treatment session to treat additional areas of the body and/or additional tissues. The health care provider may also rotate the tips during a treatment session to treat additional areas of the body or for in-treatment adjustment to increase efficacy of the treatment. The tips may comprise varying durometers and designs and be interchangeable without substantial effort or time. 
     A health care provider may use the methods described herein for a single treatment or for a treatment regimen, which may include use of one or many of the tips described herein. The length of treatment, pressure used during treatment, choice of tip, oscillation speed, and choice of body part and/or tissue to treat will vary depending on the health of a given patient and treatment goals. 
     The term “about” or “approximate” as used in the context of describing a range of volume, pressure, or temperature is to be construed to include a reasonable margin of error that would be acceptable and/or known in the art. 
     The present description uses specific numerical values to quantify certain parameters relating to the innovation, where the specific numerical values are not expressly part of a numerical range. It should be understood that each specific numerical value provided herein is to be construed as providing literal support for a broad, intermediate, and narrow range. The broad range associated with each specific numerical value is the numerical value plus and minus 60 percent of the numerical value, rounded to two significant digits. The intermediate range associated with each specific numerical value is the numerical value plus and minus 30 percent of the numerical value, rounded to two significant digits. The narrow range associated with each specific numerical value is the numerical value plus and minus 15 percent of the numerical value, rounded to two significant digits. These broad, intermediate, and narrow numerical ranges should be applied not only to the specific values, but should also be applied to differences between these specific values. 
     Furthermore, this disclosure provides various examples, as described and as illustrated in the figures. However, this disclosure is not limited to the examples described and illustrated herein, but can extend to other examples, as would be known or as would become known to those skilled in the art.
