Title: Message device with pressure dispersing edge

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to massage devices, and more particularly to a preventive and/or therapeutic massage device having a fine contact edge and a pressure dispersing edge to provide alternative modes of stretching to body tissues, such as skin, muscles, fascia, and/or tendons of a user. 
     BACKGROUND 
     The use of instrument assisted massage or soft tissue work to treat muscle injuries has existed in some form for roughly 5,000 years. In particular, ancient Chinese practitioners utilized tools to assist with tissue therapy. Such tools are typically carved out of jade stone or out of an animal horn. These tools are used by a doctor or acupuncturist to treat injuries by scraping a tool over tight muscles (also referred to as trigger points). 
     Recently, tools having a similar structure and function as these prior tools were developed. These more recent tools have been formed from stainless steel or ceramic materials. As these tools are scraped over the tight muscle, or unhealthy tissue, the metal or ceramic vibrates. There is no analogous vibration when the tools are scraped over healthy tissue. In this manner, the tool acts not only as an instrument for treating dysfunctional tissue, it also acts as a diagnostic tool. 
     One common feature among these instruments is that they include only a single, sharp and narrow contact edge. The narrow contact edge tapers down into an essentially sharp, pointed edge. When pressure is applied via the tool and this edge is scraped over tissue, a patient may experience pain or discomfort. Another feature of these instruments is that they are intended to be used solely to treat tissue after an injury has already occurred, and not for preventative tissue therapy. 
     Accordingly, a preventive and/or therapeutic massage device having a fine contact edge and a pressure dispersing edge to provide alternative modes of stretching to the body tissue of a user is disclosed that avoids the problems of known massage tools. 
     SUMMARY 
     A massage device in accordance with the present disclosure may be used as a preventive and/or therapeutic device to reduce the occurrence of tight muscles and tendons, or to relieve the symptoms associated with tight muscles. 
     The massage device includes a main body portion having first and second opposed surfaces defined between lower and upper portions and first and second ends. A fine contact edge is formed along the lower portion of the main body. An upper handle portion is formed between the first and second opposed surfaces along the upper portion of the main body. In an exemplary embodiment, the upper handle portion can form a bulbous portion that extends away from, and has a greater width than, the first and second opposed surfaces at the upper portion of the main body. A first pressure dispersing edge extends from the first opposed surface. In particular exemplary embodiments, the pressure dispersing edge can extend from the first opposed surface at an angle between 1 and 90 degrees. 
     The massage device includes first and second handles which extend from the first and second ends of the main body. In a variation, the first and second handles may extend from the first and second ends of the upper handle. 
     In addition to the lower fine contact edge, a first handle fine contact edge having a first length is defined along an end of the first handle and a second handle fine contact edge having a second length is defined along an end of the second handle. In an exemplary embodiment, the first length is longer than the second length and the first and second handle fine contact edges are arranged to apply materials, such as moisturizer, lubricant, and ointments to a skin surface. 
     In a further variation, first and second enhanced grip portions are provided along the first handle and third and fourth enhanced grip portions are provided along the second handle. The enhanced grip may be provided by adding texture to the surfaces of the handles, either in the material of the handles themselves or with additional, coating materials. 
     In a further variation, similar texturing can be provided along the upper handle portion. 
     Additionally, raised indicia can be provided on the opposed surfaces to create gripping surfaces to aid with holding the massage device and/or to provide suitable information to a user, such as sales or marketing information, or instructional information on the use of the device. 
     In a further alternate embodiment, the fine contact edge and the first pressure dispersing edge are formed as a bifurcated extension of the second and first opposed surfaces, respectively. 
     In further variations, more than one pressure dispersing edge may be utilized. For example, a first and second pressure dispersing edge can extend from the first opposed surface. Alternatively, first, second, and third pressure dispersing edges can extend form the first opposed surface. Of course, any suitable number of pressure dispersing edges may be utilized. 
     In still a further variation, a pressure dispersing bumper can be positioned on one or both of the first and second end handles of the massage device. Additionally, a contact edge of one of the first or second end handles can be rounded or curved. 
     In a particular exemplary method for using a preventative and/or therapeutic massage device to stretch body tissue, a massage device is provided having any of the suitable features described above. Either the fine contact edge, or both the fine contact edge and the pressure dispersing edge are arranged at an angle along, and in contact with, a portion of body tissue. Pressure is applied through the main body portion to a portion of body tissue and the fine contact edge is slid or scraped along a portion of body tissue to provide a first stretch of the body tissue having a first magnitude, or the fine contact edge and the pressure dispersing edge are slid or scraped along a portion of body tissue to provide a second stretch of the body tissue having a second magnitude, lesser than the first magnitude. 
     In an exemplary method, the fine contact edge or both the fine contact edge and the pressure dispersing edge are arranged along and in contact with a portion of body tissue at approximately a 45 degree angle. 
     In another exemplary method, the first or second stretches are performed to treat carpal tunnel syndrome symptoms. 
     In a further exemplary method, the massage device includes first and second handles that extend from the first and second ends of the main body and have respective first and second fine contact edges. The first or second fine contact edges can be arranged in contact along a portion of body tissue. The first and second fine contact edges can be slid along a portion of body tissue to apply a moisturizer thereto, or to stretch the portion of body tissue. 
     The numerous other advantages, features and functions of embodiments of a preventative and/or therapeutic massage device with a pressure dispersing edge will become readily apparent and better understood in view of the following description and accompanying drawings. The following description is not intended to limit the scope of the massage device, but instead merely provides exemplary embodiments for ease of understanding.

     DETAILED DESCRIPTION 
     A. Environment and Context of the Various Embodiments 
     Different embodiments of a massage device are described herein in the context of providing preventative and/or therapeutic treatment to body tissues such as skin, muscle, fascia, and tendons. The massage devices can easily be used, by both practitioners and patients themselves, in order to apply either a deep, penetrating stretch, or a less intense, gentler stretch. The gentler stretch may be used to treat acute injuries or for persons having lower pain tolerance thresholds. The massage devices can be utilized to massage any part of the user&#39;s body, for example, feet, hands, arms, legs, back, shoulders, and chest. 
     The stretches are performed by applying pressure to the body tissue through the massage device, and sliding or scraping the massage device along the body tissue. The deeper and gentler stretches may be performed daily, or prior to competitive games or practices, as part of a preventative regimen to avoid tissue injury. The stretches may also be performed as a therapeutic treatment for injured tissue. 
     Accordingly, embodiments and variations of a preventative and/or therapeutic massage device for providing a deep stretch and/or a gentle stretch are described below. 
     B. Description of a Whole Body Massage Device 
     A first embodiment of a preventative and/or therapeutic massage device  10  is shown in  FIGS. 1-7 . The massage device  10  includes a main body  12  which may be formed from any suitable material. Exemplary materials include, but are not limited to, metals, such as aluminum, titanium, and stainless steel, plastics, such as polymers, resins, polyethylene, and polyvinylchloride, ceramics, and glass and/or carbon fiber epoxy composites. The massage device  10  may be formed in any suitable manner, such as by forging, casting, machining, injection molding, layering, or any other appropriate process. 
     When materials having good thermal conductivity are used, additional therapeutic treatment may be achieved by applying temperature differentials to the body tissue to be treated by heating or cooling the massage device prior to use. 
     In this exemplary embodiment, the main body  12  has a generally elongated, half ellipsoid shape. The main body  12  has upper and lower portions and first and second ends. The main body  12  further defines first and second opposed surfaces  24 ,  22 . The first opposed surface  24  defines the gentler stretch side and the second opposed surface  22  defines the deeper stretch side, as will be discussed in more detail below. 
     The massage device  10  includes three handle portions. An upper handle portion, or top handle,  14  is formed at the upper portion of the main body  12 . The top handle may have any suitable shape and is disclosed as having an arcuate shape extending along the upper portion of the main body  12 . Edges of the upper handle  14  can extend generally perpendicularly away from the opposed surfaces  22 ,  24  of the main body  12 . 
     End handles  16  are formed extending from the first and second ends of the main body  12 . The end handles  16  may have any suitable shape, and are disclosed as generally cylindrically shaped handles oriented to extend generally perpendicularly to the opposed surfaces  22 ,  24  of main body  12  of the massage device  10 . A user may utilize any one or two of the three handles to manipulate the massage device  10 . 
     The opposed surfaces  22 ,  24  of the main body  10  are slightly angled towards each other, such that the opposed surfaces come together at the lower end of the main body  10  to define a fine contact edge  18 . The edge may be generally rounded off or tapered, so as not to be so sharp as to cause cutting or slicing injuries to the body tissue. 
     As shown in  FIGS. 5 and 6 , the fine contact edge  18  can be scraped over body tissue to provide a deep, penetrating stretch. This is accomplished by first applying a moisturizer, such as shea butter, lubricant, ointments, or other suitable material to the skin  26  in the area of the body tissue to be treated. The fine contact edge  18  of the massage device  10  is then placed in contact with the skin  26  of a portion of the body. The massage device  10  can be positioned at an angle (any suitable angle between 1 and 90 degrees may be used, 45 degrees is illustrated) to the body tissue and a pressure P is applied through the massage device  10  to the body tissue. Next, the massage device  10  is slid or scraped over the body tissue in the stretching direction S. This process is repeated over the same area of body tissue for a number of minutes until the desired amount stretching is achieved. 
     Due to the shape of the fine contact edge  18 , a deep, penetrating stretch of the body tissue, such as skin  26 , muscles, fascia, and/or tendons is achieved. The shape of the fine contact edge  18  intensifies and focuses the force applied to the massage device  10  into a deep, penetrating stretch. This stretch can be used as a preventative measure to avoid injuries to the body tissue. 
     As shown in  FIG. 3 , as an alternative, or to treat injuries to the body tissue, a pressure dispersing edge or bumper  20  is formed along, and extending approximately perpendicularly from, the first opposed surface  24  near the lower end thereof. As illustrated, the pressure dispersing bumper  20  is formed along substantially the entire length of the massage device  10 . It will be recognized that the pressure dispersing edge  20  may also be formed along only a portion of the first opposed side  24 , or in segments along the first opposed side  24 , or in any other suitable configuration. The profile of the pressure dispersing edge  20  may be any suitable shape in order to provide the necessary stretching, while also dispersing pressure to provide a less penetrating stretch. 
     As shown in  FIG. 7 , a less aggressive, gentler stretch can be achieved by utilizing the fine contact edge  18  in combination with the pressure dispersing edge  20 . The stretch is performed in a similar manner as discussed above, with the exception that both the fine contact edge  18  and the pressure dispersing edge  20  are placed in contact with the skin  26 . Also, when the massage device  10  is used to treat injured body tissue, additional moisturizer and/or lubricant, such as shea butter may be used. Again, a pressure P is applied to the body tissue through the massage device  10 , via both the fine contact edge  18  and the pressure dispersing edge  20 , and the massage device is slid or scraped along the skin  26  in the stretching direction S. 
     Since the pressure P applied through the massage device  10  is divided between the fine contact edge  18  and the pressure dispersing edge  20 , a less aggressive, gentler stretch of the body tissues is achieved. This type of stretch is beneficial to use with persons having low pain thresholds, or in order to provide therapeutic treatment to body tissues with acute injuries. Again, the process is repeated for several minutes over the same area of tissue in order to achieve the desired results. 
     The processes discussed above can be used to treat the tissue of any suitable part of the body, for example the thigh, gluteal, hamstring, and leg muscles. Additionally, the muscles located above and below the knee may also be treated. Further, the arms, forearms, pectorals, chest, and neck can be treated using the processes discussed above. 
     The massage device  10  can be used in combination with traditional stretching protocols to enhance such protocols for preventing and treating injuries to body tissue. The use of the massage device  10  on soft tissue, in particular around a joint of the body, will stretch the soft tissue and allow the joint to become more loose and flexible. 
     In order to aid with self use of the massage device  10 , a fully detailed instruction manual may be provided therewith with explanations of use of the massage device  10  for self stretching and massage. A kit may also be provided that can include a carrying pouch, the massage device  10 , an instructional video (any suitable format), and moisturizer and/or lubricant, such as shea butter. 
     While the above description of the massage device  10  provides an exemplary configuration of a massage device having a pressure dispersing edge, additional embodiments, configurations, and variations are described below. 
     C. Description of a Carpal Tunnel Massage Device 
     While the massage device  10  discussed above may be utilized on any part of the body, the massage device  30  shown in  FIGS. 8-10  is particularly arranged for use in the treatment of carpal tunnel injuries, pain, and symptoms. Of course, it will be recognized that the massage device  30  can also be used to treat any body part or tissue. 
     The massage device  30  resembles the massage device  10  discussed above. Therefore, a detailed explanation of features previously discussed is not provided. The massage device  30  may have a generally similar shape to the massage device  10 , including a main body  32 , an upper handle  34 , and first and second opposed sides  44 ,  42 . Like the massage device  10 , a fine contact edge  38  and a pressure dispersing edge  40  are provided along the lower portion of the massage device  30 , the use of which is discussed above in detail. 
     Since the massage device  30  is designed to treat carpal tunnel symptoms/injuries, the overall size of the device may be smaller, as would be appropriate to massaging the wrist, hand, and finger joints. 
     The first and second end handles  46 ,  50  have longitudinal portions extending from the main body portion  32  in a substantially parallel manner with respect to the fine contact edge  38 . The first and second end handles  46 ,  50  have first and second contact edges  48 ,  52  respectively formed thereon, and perpendicularly to the longitudinal portions thereof. The first contact edge  48  can be longer than the second contact edge  52  to provide contact edges appropriate for use with differing areas of the body. 
     For example, the second contact edge  52  may be used, in a manner described above, to provide a deep penetrating stretch to the body tissues around, and between the fingers of the hand, while the first contact edge  48  can be used on the body tissues around the palm and the back of the hand. 
     The first and second contact edges  48 ,  52  can also be used as applicators to apply lubricants, ointments, and moisturizers, such as shea butter. A small amount of material can be placed upon the contact edge, which may then be drawn across the skin to apply the material. 
     Since the massage device  30  will be generally smaller in shape, it may be more difficult to maintain an appropriate grip. Additionally, the use of lubricants, ointments, and moisturizers, such as shea butter, may make the smooth surfaces of the massage device  30  difficult to grip. Accordingly, enhanced gripping portions  36  utilizing a texture feature can be provided. 
     The enhanced grip portions can be positioned in any suitable location on the main body portion  32 , or on opposed first and second end handles  46 ,  50 . The enhanced grip portions  36  can be provided on both of the surfaces of each of the first and second end handles  46 ,  50 , corresponding to the opposed surfaces  42 ,  44  of the main body portion  32 . The texture feature of the enhanced grip may be formed in any suitable manner, such as by applying a friction tape or other coating to the surfaces, providing integral texture on the surfaces, providing dimples or drilled holes in the surfaces, or any other appropriate structure. 
     In addition to the grip portions  36 , indicia  54  can be provided on the opposed surfaces  42 ,  44  of the main body  32  below or near the upper handle  34  in order to provide information to a user and/or to enhance the gripping of the opposed surfaces  42 ,  44 . Such indicia  54  may be printed or painted directly on the opposed surfaces  42 ,  44 . Alternatively, the indicia  54  may be a printed label attached to the opposed surfaces  42 ,  44  via a suitable adhesive. The indicia  54  may also be raised or depressed lettering integrally formed with the main body portion  32 . While the indicia  54  is exemplarily shown as lettering, it will be recognized that the indicia may be numbers, letters, any graphical illustration, or any other design It will also be recognized that the enhanced grip features and indicia of the massage device  30  can also be provided to the massage device  10 . 
     The massage device  30  is used in the same manner as discussed above with respect to massage device  10  in order to treat the symptoms of carpal tunnel syndrome, such as pain and numbness of the hand and fingers. Further, the fine contact edge  38  and the pressure dispersing edge  40  can be used to stretch the tissues in the wrist, forearm, and arm. Further, while massage device  30  is designed to treat carpal tunnel syndrome symptoms, it can also be used to stretch the tissues of any other part of the body as well. 
     Variations of the carpal tunnel massage device are discussed next. 
     D. Description of a Variation of a Carpal Tunnel Massage Device 
     A variation of a carpal tunnel massage device  60  is shown in  FIGS. 11 and 12 . Of course, the variations described herein can also be applied to the whole body massage device. The massage device  60  is comparable in form and function to those previously discussed and includes a main body portion  62  with upper and lower portions, and first and second ends. An upper handle  64  is positioned along the upper portion and first and second end handles  76 ,  80  are positioned at the respective ends. The first end handle  76  has a larger first contact edge  78 , and the second end handle  80  has a smaller second contact edge  82 . Enhanced grip portions  66  can be provided on each of the first and second end handles  76 ,  80 . 
     As in previous embodiments, the main body portion  64  has first and second opposed sides  74 ,  72 . The first and second opposed sides  74 ,  72  can include indicia  84  to engage the fingers  86  of the user to enhance the user&#39;s grip and/or to provide information. 
     As shown in  FIG. 12 , the lower portion of the main body  62  is bifurcated to form the fine contact edge  68  and the pressure dispersing edge  70 . The fine contract edge  68  extends from the second opposed side  72  and is formed in an elongated, narrow, pointed shape in order to provide a deeper penetrating stretch. The pressure dispersing edge  70  extends from the first opposed side  74  and is formed with a wider, more blunted shape in order to provide a gentler, less aggressive stretch. 
     The use of the fine contact edge  68  and the pressure dispersing edge  70  to provide the two different types of stretching is the same as described above with respect to massage device  10 . 
     Another variation of a carpal tunnel massage device is discussed next. 
     E. Description of a Second Variation of a Carpal Tunnel Massage Device 
     A second variation of a carpal tunnel massage device  90  is shown in  FIGS. 13 and 14 . This variation is like the massage device  30 , and includes a main body portion  92  with upper and lower portions and first and second ends. An upper handle  94  is formed at the upper portion and first and second end handles  106 ,  110  are formed extending from the first and second ends. The first end handle  106  has a larger first contact edge  108 , and the second end handle  110  has a smaller second contact edge  112 . Enhanced grip portions  96  can be provided on each of the first and second end handles  106 ,  110 . 
     Like previous embodiments, the main body portion  92  has first and second opposed sides  104 ,  102 . The first and second opposed sides  104 ,  102  can include indicia  114  to engage the fingers of the user to enhance the user&#39;s grip and to provide information. 
     A fine contact edge  98  is formed at the lower portion between the first and second opposed sides  104 ,  102 . The use of the fine contact edge  98  is the same as described above in detail. 
     In a variation from previous embodiments, a magnetic strip of material  116  may be embedded near the lower portion along the second opposed surface  102 . Such a magnetic strip can provide therapeutic effects by altering the magnetic fields of the tissue as the massage device  90  is scraped or slid along the body tissue. While an embedded magnetic strip is disclosed, it will be recognized than any suitable configuration may be used. For example, a magnetic strip attached to the surface, or a number of magnetic segments embedded or attached to the surface in a spaced apart manner may be used. 
     In a further variation, more than one pressure dispersing edges  100  extend from the first opposed side  104 . The use of the pressure dispersing edges is the same as described above with respect to massage device  10 . The difference being that the three disclosed pressure dispersing edges each increase in height or extension from the lower edge toward the upper portion. Thus, the edges  100  will act in the following manner, when stretching the body tissue, the tissue that is not caught by the shortest edge, will be caught by the second or the tallest edge, such that all of the body tissue will be appropriately stretched, in the gentler manner previously discussed. 
     It will be recognized that more than or less than three pressure dispersing edges may be utilized. 
     Another variation of a carpal tunnel massage device is discussed next. 
     F. Description of a Third Variation of a Carpal Tunnel Massage Device 
     A third variation of a carpal tunnel massage device  120  is shown in  FIGS. 15 and 16 . This variation is similar to the massage device  30 , and includes a main body portion  122  having a broad blade-like shape, like a putty knife, with upper and lower portions and first and second ends. An upper handle  124  is formed at the upper portion and first and second end handles  136 ,  140  are formed extending from the first and second ends. Enhanced grip portion  126  is formed on the upper handle  124 , which may be somewhat cylindrical in shape. The first end handle  136  has a larger first contact edge  138 , and the second end handle  140  has a smaller second contact edge  142 . 
     As with previous embodiments, the main body portion  122  has first  134  and second opposed sides. A fine contact edge  128  is formed at the lower portion between the first and second opposed sides. The use of the fine contact edge  128  is the same as described above in detail. 
     Again, similarly to previously discussed embodiments, a pressure dispersing edge  130  extends from the first opposed side  134  and functions in a manner as described above. 
     The larger upper handle portion  124  and the enhanced gripping portion  126  thereon increase the ability of the user to manipulate the massage device  120 . 
     Next, variations of pressure dispersing edges are discussed. 
     G. Variations of Pressure Dispersing Edges 
     Three variations of pressure dispersing edges are shown in  FIGS. 17-19 . 
     As shown in  FIG. 17 , the massage device  150  has a main body portion  152  with end handles having a contact edges  158  in a manner previously discussed. As also previously discussed, a fine contact edge  154  is formed between first and second opposed side surfaces. 
     In the variation shown in  FIG. 17 , the pressure dispersing edge  156  extends away from the first opposed side at a downward angle, as opposed to perpendicularly as previously discussed. The angle can be any angle between 1 and 90 degrees, and is shown at an approximately 45 degree angle in  FIG. 17 . The variation of this angle may be used to alter the effects of the pressure dispersing edge  156 . 
     In another variation, as shown in  FIG. 18 , a pressure dispersing edge  156  extends substantially perpendicularly from each of the first and second opposed sides of the main body. Thus, the massage device  150  can be used in back and forth motion to apply a gentler stretch to the body tissue, without having to remove the massage device  150  from contact with the body tissue. 
     In a still further variation, a pressure dispersing edge  156  extends substantially perpendicularly from each of the first and second opposed sides of the main body in an offset manner. Thus, in addition to allowing the back and forth massage motion just discussed, the magnitude of the gentle stretch can be varied from one direction to the other. 
     While these variations are described in the context of a carpal tunnel massage device, it will be recognized that they are equally applicable to a whole body massage device. 
     Next, a further embodiment of a carpal tunnel massage device is described. 
     H. Description of a Fourth Variation of a Carpal Tunnel Massage Device 
     A fourth variation of a carpal tunnel massage device  160  is shown in  FIGS. 20-22 . This variation resembles the massage device  30 , and includes a main body portion  162  with upper and lower portions and first and second ends. An upper handle  164  is formed at the upper portion. The upper handle  164  is formed as a bulbous portion having an enlarged width for enhanced comfort and fit for the user&#39;s hand  186 . 
     First and second end handles  176 ,  180  are formed extending from the first and second ends. The first end handle  176  has a larger first contact edge  178 , and the second end handle  180  has a smaller second contact edge  182 . Enhanced grip portions  166  can be provided on each of the first and second end handles  176 ,  180 . 
     Similarly to previous embodiments, the main body portion  162  has first and second opposed sides  174 ,  172 . The first and second opposed sides  174 ,  172  can include indicia  184  to engage the fingers of the user to enhance the user&#39;s grip and to provide information. 
     A fine contact edge  168  is formed at the lower portion between the first and second opposed sides  174 ,  172 . The use of the fine contact edge  168  is the same as described above in detail. The first and second opposed sides  174 ,  172  define a narrow width at the formation of the fine contact edge  168  and may define a slightly larger width at the upper portion thereof. 
     As shown in  FIG. 22 , a pressure dispersing edge  170  of the type previously described is positioned along the lower portion of the first opposed side  174  for use in the manner as detailed above. 
     In order to enhance the gripping function provided by the upper handle  164 , the width of the bulbous upper handle  164  is larger than the width defined between the first and second opposed sides  174 ,  172  so that the palm of the hand  186  can rest upon the bulbous portion while the fingers wrap around the bulbous portion. 
     An illustration of the use of an end contact edge to apply material is shown in  FIG. 22 . Material  187 , such as moisturizer, lubricant, or ointment is spread over the firs end handle contact edge  178 . This edge is brought into contact with the skin  188  and the user grips the first handle  176  with their hand  186  to spread the material  187  along the skin  188 . Thus, friction between the massage device and the skin can be reduced, and therapeutic benefits of the material can be spread over a large area. 
     Next, a further embodiment of a carpal tunnel massage device is described. 
     I. Description of a Fifth Variation of a Carpal Tunnel Massage Device 
     A fifth variation of a carpal tunnel massage device  190  is shown in  FIG. 23 . This variation is comparable to the massage device  30 , and includes a main body portion  192  with upper and lower portions and first and second ends. An upper handle  194  is formed at the upper portion and first and second end handles  202 ,  206  are formed extending from the first and second ends. The first end handle  202  has a larger first contact edge  204 , and the second end handle  206  has a smaller second contact edge  208 . Enhanced grip portions  196  can be provided on each of the first and second end handles  202 ,  206 . 
     As with previous embodiments, the main body portion  192  has first and second opposed sides that can include indicia  210  to engage the fingers of the user to enhance the user&#39;s grip and to provide information. 
     A fine contact edge  198  is formed at the lower portion between the first and second opposed sides. The use of the fine contact edge  198  is the same as described above in detail. A pressure dispersing edge  200  of the type discussed above is positioned along the lower portion of the first opposed side for use in the manner as previously explained. 
     With regard to the first and second end handles  202 ,  206 , instead of extending in a substantially parallel manner to the fine contact edge  198 , they can be shifted along the perimeter of the main body portion  192  so that they extend off at an angle with respect to the fine contact edge  198 . The angle may be any desired angle, and is shown as an approximately 45 degree angle. 
     In this manner, the comfort and fit of the end handles  202 ,  206  may be modified to accommodate different users or stretches. 
     A further variation of a carpal tunnel massage device is described below. 
     J. Description of a Sixth Variation of a Carpal Tunnel Massage Device 
     A fifth variation of a carpal tunnel massage device  220  is shown in  FIGS. 24 and 25 . This variation is similar to the massage device  160 , and includes a main body portion  222  with upper and lower portions and first and second ends. An upper handle  224  is formed at the upper portion and first and second end handles  230 ,  236  are formed extending from the first and second ends. The first end handle  230  has a straight, fine contact edge  232 , and the second end handle  236  has a curved or rounded contact edge  238 . The straight, fine contact edge  232  functions as previously described. The rounded or curved contact edge  238  allows a user to provide an even deeper and penetrating massage than can be obtained by the use of a straight contact edge. 
     In addition to the fine contact edge  232 , the first end handle  230  also includes a pressure dispersing edge  234  along at least one side thereof, as shown in  FIGS. 24 and 25 . This pressure dispersing edge  234  functions in a manner previously described in detail, and no further discussion is necessary. The pressure dispersing edge  234  allows a user to provide a more relaxed stretch to smaller areas that may not be reached with a larger edge 
     Like previous embodiments, the main body portion  222  has first and second opposed sides that can include indicia  240  to engage the fingers of the user to enhance the user&#39;s grip and to provide information. 
     A fine contact edge  226  is formed at the lower portion between the first and second opposed sides. The use of the fine contact edge  226  is the same as described above in detail. A main pressure dispersing edge  228  of the type previously described is positioned along the lower portion of the first opposed side for use in the manner as previously discussed. 
     With the construction of this embodiment, harder to reach areas, such as between knuckles and fingers, can utilize the benefits of the more relaxed stretch that can be provided by the use of a pressure dispersing edge  234  along a handle. Further, an even deeper stretch can be provided to the harder to reach areas by use of the rounded or curved edge  238  of the second handle  236 .
