       [0001]    This application claims the benefit of U.S. Provisional Patent Application No. 62/045,309 filed Sep. 3, 2014. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    This invention relates to a device for use in facilitating or assisting a user in enhancing proprioception during breathing exercises. This invention also relates to an associated method utilizing the device. 
         [0003]    The majority of the U.S. population is obese (55% plus another 20% is overweight) which means that a majority have elevated cortisol levels . In addition, many emotional afflictions find their roots in spinal misalignment and improper nerve stimulation owing to tense back muscles and imbalances from extra weight. 
       OBJECTS OF THE INVENTION 
       [0004]    An object of the present invention is to provide a device for use by an individual during breathing exercises giving a traction like effect from the pressure and stimulation and a massage action to the spine. 
         [0005]    A related object of the present invention is to provide such a device that furnishes feedback to the user&#39;s ribcage and spine during inspiration and expiration, facilitates a relaxation and recovery effect. 
         [0006]    The present invention seeks in part to provide a device and a related spinal massage method that favorably acts on spinal nerves, assists in spinal adjustment and alignment, and has beneficial effects on the parasympathetic nervous system. 
         [0007]    These and other objects of the present invention will be apparent to one skilled in the art from the drawings and descriptions herein. Although every feature of the invention is attained in at least one embodiment of the invention, there is not necessarily any one embodiment that achieves all of the objects of the invention. 
       SUMMARY OF THE INVENTION 
       [0008]    A device for facilitating or enhancing proprioceptive feedback particularly during breathing exercises comprises, in accordance with the present invention, two elongate resiliently compressible members so coupled together as to remain in parallel relation during use of the device when positioned against the back of a user. The device further comprises a fastening or coupling element configured for attachment to a user so that the resiliently compressible members are held against the user&#39;s back parallel to the user&#39;s spine and on opposites thereof. 
         [0009]    The device is provided in two main versions, each configured for a respective mode of use. One version is adapted for use in a sitting posture, while the other version is designed for a supine posture. 
         [0010]    In the wearable sitting-posture version of the proprioception feedback device, the user attachment element may include a pair of shoulder straps. Alternatively, the user attachment element may take the form of a vest, e.g., a collection of straps that effectively encircle the thorax of the user. In another alternative, the user attachment element may take the form of a strap, band or belt that is fastened about the rib cage or torso of the user, below the breasts or pectoral muscles. 
         [0011]    In the supine version of the present device, the user attachment element preferably takes the form of a strap, band or belt (e.g., with releasable VELCRO™ fasteners) that wraps around the torso of the user, especially, about the rib cage below the breasts or pectoral muscles. 
         [0012]    Pursuant to another feature of the present invention, the proprioception assist device, particularly the upright or sitting-posture version, may further comprise a flexible elongate tensile member attachable at respective ends in regions about respective hands of the user, for instance, via loops and so coupled directly or indirectly to the resiliently compressible members so as to extend behind or in front or to the sides of the user during use of the device. Where the user attachment element comprises straps, buckles, and flexible cords or ties in an arrangement having a back portion, a front portion and side portions, the resiliently compressible members are connected to the user attachment element or assembly at the back portion thereof. Likewise, the tensile member is coupled to the back portion of the user attachment element. 
         [0013]    Pursuant to more particular features of the present invention, the tensile member is slidably attached to the resiliently compressible members or the user attachment element (e.g., via one or more loops) and is at least partially elastic. The tensile member may take the form of a bungee cord or stretchable rubber tubing provided at opposite ends with a pair of loops or handles releasably securable to respective hands of the user. 
         [0014]    The resiliently compressible members are preferably made of a foam material and more preferably of a closed cell foam material such as EVA. The cylindrical sections may be cut longitudinally through the center axis so that the resiliently compressible members are semi-cylindrical with a first, cylindrical, outer surface and a second, flat or planar, outer surface contiguous therewith. 
         [0015]    The proprioception assist device, whether the upright sitting version or the supine version, may include a pair of slip covers or casings (different from the user attachment elements) that receive the resiliently compressible members, for purposes of providing a more pleasing and warming contact with the user, if a neoprene material or similar fabric is used. Alternatively, a single cover or casing may contain both resiliently compressible members. In that case, the covers or casings may serve in part to hold the resiliently compressible foam members in parallel to one another with space between for spinous process. 
         [0016]    A method for facilitating or enhancing proprioceptive feedback comprises, in accordance with the present invention, (i) providing two elongate resiliently compressible members coupled to one another so as to maintain a mutually parallel configuration, (ii) attaching the resiliently compressible members to a user, so that the resiliently compressible members are disposed against the user&#39;s back in parallel to the user&#39;s spine and on opposite sides of the spine, and (iii) moving the user&#39;s back against the resiliently compressible members. Preferably, the resiliently compressible members are positioned at least alongside the thoracic region of the spine. Where the user assumes a sitting posture, the resiliently compressible members are disposed only in contact with the thoracic region of the spine. 
         [0017]    Where the user assumes a supine posture (and dons the supine version of the device described above), the compressible members may extend to the head of the user. In that case, a third resiliently compressible member may be provided, attached to one end of the spinal members and extending perpendicularly thereto, for forming a head abutment providing resistance to a rearward pressing of a user&#39;s head. This assists the user in applying traction to the spine, particularly if the supine version of the device is provided also with ankle straps. 
         [0018]    The movement of the back against the elongate compressible spinal members during use of the device may result naturally from breathing, particularly via an expansion and contraction of the diaphragm and rib cage. The method enables users to bring awareness to the posterior part of the trunk while mobilizing the interior of the body, allowing trunk stabilization and respiration into the posterior rib cage, which stimulates the parasympathetic nervous system. The method and device of the present invention facilitates a cognitive component that can work the brain in tandem with the body. 
         [0019]    It is contemplated that the stimulation of the parasympathetic nervous system reduces the concentration of cortisol in the user&#39;s body and leads over a long term to weight reduction. 
         [0020]    In the wearable or sitting-posture embodiment of the proprioception assist device, the disposing of the resiliently compressible members against the user includes attaching the resiliently compressible members to the user via a body assembly, such as shoulder straps and optionally one or more chest straps or bands. Where the device includes an elongate tensile member (bungee cord or stretchable rubber tubing) coupled to the body assembly, the attaching to the user may include disposing the elongate tensile member on the back side of the user. The method then further comprises attaching ends of the at least one elongate tensile member to the user&#39;s hands and exerting tension on the elongate tensile member (e.g., bungee cord, rubber tubing). 
         [0021]    During performance of the method, the user may lie on a horizontal surface (reclining position) or a seat back (sitting position). The principal motion of the user&#39;s back against the resiliently compressible members arises from the breathing process. 
         [0022]    A back massage/stimulation and feedback assist device comprises, in accordance with the present invention, two elongate resiliently compressible members, at least one first coupling element connected to the resiliently compressible members so as to hold the resiliently compressible members in parallel relation to one another and at a predetermined distance from one another (preferably about ¼ inch so that the rollers rest on the ribs and not on the shoulder blades), and at least one second fastening or coupling element for removably attaching the resiliently compressible members to a user. The first coupling member may take the form of one or more straps that are connected (e.g., glued) to the outer surfaces of the resiliently compressible members. Alternatively, the first coupling member may take the form of a casing or envelope that surrounds and encloses the resiliently compressible members. The casing or envelope may have a pair of chambers, one for each of the resiliently compressible members, with the chambers being spaced a predetermined distance (preferably approximately ¼ inch). 
         [0023]    The use of two resiliently compressible members in parallel with one another creates an effective spacing enabling the spinous processes of the vertebrae to fit comfortably in between without pressure on them. The resiliently compressible members may engage one another along their lengths, with the protection to the spine being afforded by the tapering cross-sections of the compressible members. 
         [0024]    The maximum distance between the resiliently compressible members may be ¼ inch (the distances between the points of maximum thickness or height of the compressible members is naturally greater). The shapes of the resiliently compressible members in that event channel the user&#39;s weight (reclining mode) or applied pressure away from the spinal column itself to the supporting musculature on opposite sides of the spine. 
         [0025]    The coupling element or elements binding the resiliently compressible members to one another serve to hold the resiliently compressible members together in opposition to a spreading or dislocating force naturally exerted by the user&#39;s back during use of the device. 
         [0026]    The resiliently compressible members are preferably made of a foam material and have an at least partially cylindrical outer surface. At least one casing or cover may be provided to enclose one or both of the resiliently compressible members. 
         [0027]    The proprioception assist device may further comprise a flexible elongate tensile member coupled to the resiliently compressible members and the coupling element for extending behind/in front/to the sides of the user during use of the device, the tensile member being attachable at respective ends in regions about respective hands of the user. The tensile member may include a pair of loops or handgrips releasably securable about respective hands of the user. 
         [0028]    A device in accordance with the present invention may be used in massaging the back, particularly the muscles and nerves in the thoracic region, on opposite sides of the spine. Using the device favorably acts on spinal nerves, assists in spinal adjustment and alignment, and has beneficial effects on the parasympathetic nervous system, allowing better relaxation and digestion by reducing stress which in turn reduces cortisol production. The method using the device of the present invention may assist in spinal nerve adjustment, posture correction and/or equilibration of the parasympathetic nervous system. 
         [0029]    The device and method of the present invention may be used by an individual in breathing exercises and light-pressure back massage action. The device furnishes feedback to the user&#39;s ribcage and spine during inspiration and expiration, which facilitates a coordination of cognitive with the physical body. Moreover, use of the device increases the flow of oxygen through the system and improves the functioning of the trunk muscles. Supine versions of the resiliently compressible members allow trunk support from head to tailbone and the head rest, rib wrap and ankle restraint provide a traction like effect, that magnifies the breathing facilitating a beneficial and pleasurable effect on the parasympathetic nervous system. 
         [0030]    The device and method of the present invention may additionally assist in massaging organic tissues located along and adjacent to the spine, improving nerve response and stabilization. A double foam member system provides comfort and support allowing longer and/or more frequent breathing and massage exercise routines, which helps with trunk stabilization and respiration into the posterior rib cage, enhancing oxygen circulation. Frequent use of the device increases the ability of the ribs to expand, allowing more oxygen to enter the lungs and become absorbed onto the blood. In addition, muscles of the pelvic floor are stabilized and the spine is strengthened, protecting the bones and improving alignment. This in turn increases the cognitive coordination of physical performance during functional activities and stimulates healthier posture.

     DETAILED DESCRIPTION 
       [0051]    As illustrated in  FIGS. 1 and 2 , a wearable proprioception assist device  10  particularly for use during breathing exercises in a sitting posture comprises a pair of elongate resiliently compressible members  12  and  14  each approximately 7 inches in length and a fastening assembly  16  including three coupling elements  18 ,  20  and  22  in the form of thin flexible bands attached to and encircling the resiliently compressible members so as to maintain the resiliently compressible members in parallel relation to one another and at a predetermined maximum spacing, exemplarily about ¼ inch. Coupling bands  18 ,  20 , and  22  may be attached via adhesive to the elongate resiliently compressible members  12  and  14 . 
         [0052]    Compressible members  12  and  14  are preferably made of a foam material and more preferably of a closed cell foam material such as polyethylene or ethylene vinyl acetate (EVA). Members  12  and  14  are exemplarily half sections of polymeric foam cylinders. In that case the cylindrical sections are cut longitudinally through center axes  24  and  26  so that compressible members  12  and  14  are semi-cylindrical each with a first, cylindrical, outer surface  28  and  30  and a second, flat or planar, outer surface  32  and  34  contiguous therewith. Alternatively, resiliently compressible members  12  and  14  may be manufactured by casting or molding polymeric (PE, EVA) foam material into the final shape, accordingly without use of a preform. 
         [0053]    Fastening assembly  16  of wearable proprioception assist device  10  may include user attachment elements such as a pair of shoulder straps  40  and  42  each fastened (e.g., via adhesive or stitching) to coupling bands  18  and  22 . Shoulder straps  40  and  42  hold the assist device  10  and particularly compressible members  12  and  14  against the user&#39;s back so that the compressible members are parallel to the user&#39;s spine—preferably the thoracic region of the spine—and on opposites thereof. 
         [0054]    Fastening and user attachment assembly  16  may be optionally provided with componentry, for instance, a pair of belt segments  44  and  46  having cooperating buckle parts  48  and  50 , for suitably fixing the assembly about the thorax or torso of the user, with the belt straps buckled to one another across the front of the user&#39;s chest. Thus, fastening and user attachment assembly  16  may be configured for positioning and maintaining resiliently compressible members  12  and  14  along the thoracic part of the spinal column thus increasing the effect. 
         [0055]    Wearable proprioception assist device  10  optionally further comprises a flexible elongate tensile member  52  such as a bungee cord or stretchable rubber tubing having loops or rings  54  and  56  at opposite ends for coupling the bungee cord (or tubing) to respective hands of the user. Bungee cord  52  is coupled to fastening and user attachment assembly  16  so that the bungee cord extends behind the user&#39;s back. As shown in  FIGS. 1 and 2 , bungee cord  52  may slidably traverse an elongate fabric tube  58  attached to compressible members  12  and  14  along a front or rear side thereof. Tube  58  may be attached to band  20  by glue or stitching and extend therealong transversely to compressible members  12  and  14 . (Alternatively, tube  58  may be removably attached to compressible members  12  and  14  exemplarily via VELCRO type hook and loops fasteners or by snap-lock fasteners. This option may be used in other embodiments as well.) Bands  18 ,  20 , and  22  of fastening and user attachment assembly  16  together with opposite end portions of shoulder straps  40  and  42  and proximal end portions of belt segments  44  and  46  constitute a back side of fastening and user attachment assembly  16 , while middle portions of shoulder straps  40  and  42  and distal end portions of belt segments  44  and  46 , together with buckle parts  48  and  50  constitute left and right sides and a front side of the fastening and user attachment assembly  16 . 
         [0056]    As depicted in  FIGS. 3 and 4 , another wearable proprioception assist device  110  also particularly for use during breathing exercises in a sitting posture comprises a pair of elongate resiliently compressible members  112  and  114  each approximately 7 inches in length and a fastening and user attachment assembly  116  which in turn comprises a slip cover assembly  118  including a pair of fabric casings or bags  120  and  122  defining a pair of chambers  124  and  126  that receive and enclose respective compressible members  112  and  114  and maintain the resiliently compressible members in parallel relation to, and at a maximal distance from, one another. Casings or bags  120  and  122  are connected to one another by one or more fabric strips  128  and  130  that are typically stitched to the casings. 
         [0057]    As described hereinabove with respect to the embodiment of  FIGS. 1 and 2 , compressible members  112  and  114  are preferably made of a polymeric foam material and more preferably of a polymeric closed cell foam material. Compressible members may be made from cylindrical preforms that are cut longitudinally through center axes  132  and  134  so that compressible members  112  and  114  are semi-cylindrical each with a first, cylindrical, outer surface  136  and  138  and a second, flat or planar, outer surface  140  and  142  contiguous therewith. Compressible members  112  and  114  optionally have longitudinal grooves  144  and  146  in the respective flat surface  140  and  142 . 
         [0058]    Fastening and user attachment assembly  116  of wearable assist device  110  includes a pair of shoulder straps  148  and  150  each fastened (via adhesive or stitching) to casings or bags  120  and  122 . Shoulder straps  148  and  150  hold the assist device  110  and particularly compressible members  112  and  114  in position along the user&#39;s back so that the compressible members are parallel to the user&#39;s spine and on opposites thereof. Shoulder straps  148  and  150  may be supplemented by a belt or strap attached to casings or bags  120  and  122  so as to be disposable about the torso of the user, exemplarily just below the pectoral muscles or breasts. For instance, fastening and user attachment assembly  116  may be provided with componentry, for instance, a pair of belt segments  152  and  154  having cooperating buckle parts  156  and  158 , for suitably fixing the assembly about the torso of the user, with the belt straps buckled to one another across the front of the user&#39;s chest. Thus, fastening and user attachment assembly  116  may be configured for positioning and maintaining resiliently compressible members  112  and  114  along the thoracic part of the user&#39;s spinal column. 
         [0059]    Wearable proprioception assist device  110  further comprises a flexible elongate tensile member  160  such as a bungee cord or stretchable rubber tubing having loops  162  and  164  at opposite ends for coupling the bungee cord to respective hands of the user. Bungee cord  160  extends behind the user&#39;s back during use of the device. As shown in  FIGS. 3 and 4 , bungee cord  160  may slidably traverse an elongate fabric tube  166  attached to casings or bags  120  and  122  (and thus to compressible members  112  and  114 ) along a front or rear side thereof. Tube  166  may be attached to assembly  118  by glue or stitching. Casings  120  and  122  of fastening and user attachment assembly  116  together with opposite end portions of shoulder straps  148  and  150  and proximal end portions of belt segments  152  and  154  constitute a back side of the user attachment assembly  116 , while middle portions of shoulder straps  148  and  150  and distal end portions of belt segments  152  and  154 , together with buckle parts  156  and  158  constitute left and right sides and a front side of the user attachment assembly. 
         [0060]    As illustrated in  FIGS. 5 and 6 , a proprioception assist device  210  for preferred use during breathing exercises in a supine position of the user (see  FIG. 7 ) comprises a pair of elongate resiliently compressible members  212  and  214  each approximately 40 inches in length. Four coupling elements  218 ,  220 ,  222  and  224  in the form of thin flexible bands are attached to and encircle the resiliently compressible members  212  and  214  so as to maintain the resiliently compressible members in parallel relation to one another. Coupling bands  218 ,  220 ,  222 , and  224  may be attached via adhesive to outer surfaces of the elongate resiliently compressible members  212  and  214 . 
         [0061]    Members  212  and  214  are cylinders of polymeric foam material with respective center channels or lumens  236  and  238 . Optionally, a pair of stiff thermoplastic or polymeric tubes  240  and  242  may be inserted into center channels or lumens  236  and  238 , respectively. In addition to or in place of bands  218 ,  220 ,  222 , and  224 , an endless connecting cord  244  may traverse tubes  240  and  242  in a loop to hold compressible members  212  and  214  relative to one another. 
         [0062]    Supine proprioception assist device  210  may include a cover or casing  216  made of plastic film or fabric material that encases and holds compressible members  212  and  214 . Cover or casing  216  and coupling bands  218 ,  220 ,  222 ,  224  (and/or cord  244 ) provide compressible members  212  and  214  with a maximum spacing or distance D. That distance is preferably about ¼ inch. 
         [0063]    As illustrated in  FIGS. 8 and 9 , a further wearable proprioception assist device  310  for preferred use during breathing exercises in a sitting position comprises a pair of elongate semi-cylindrical resiliently compressible members  312  and  314  each approximately 7 inches in length. Compressible members  312  and  314  are preferably made of a foam material and more preferably of a closed cell foam material. One or more coupling elements  318  in the form of flattened strips or flanges or webs are attached to the resiliently compressible members  312  and  314  along flat sides  340 ,  342  thereof so as to maintain the resiliently compressible members in parallel relation to one another and at a substantially fixed spacing or separation (about ¼ inch). Coupling web(s)  318  may be attached via adhesive to flat outer surfaces  340 ,  342  of the elongate resiliently compressible members  312  and  314 , opposite convex or cylindrical surfaces  344  and  346  thereof. Alternatively, compressible members  312  and  314  and web(s)  318  may be integrally molded as a unitary object. 
         [0064]    Compressible members  312  and  314  are each provided at respective opposing ends with loops or eyelets  320 ,  322  and  324 ,  326  for attachment, to the compressible members, of a user attachment assembly in the form of two shoulder straps  328  and  330 . Straps  328 ,  330  may be elastic strips or non-elastic belts. If straps  328 ,  330  are made of inelastic material such as fabric, buckles (not shown) may be attached to the straps for adjusting the lengths thereof. 
         [0065]    Wearable proprioception assist device  310  optionally includes a cover or casing  316  made of plastic film or fabric material that encases and holds compressible members  312  and  314 . Straps  328 ,  330  pass through slits in the cover or casing  316 . 
         [0066]    An elongate tensile member  352  such as a bungee cord or stretchable rubber tubing is coupled to compressible members  312 ,  314  and extends behind the user during use of the device. Bungee cord  352  has loops  354  and  356  at opposite ends for coupling the bungee cord to respective hands of the user. Bungee cord  352  slidably traverses channels  358 ,  360  in compressible members  312  and  314 . 
         [0067]    Coupling web  318  (assuming one such connector strip) (and optionally casing  316 ) provides compressible members  212  and  214  with a maximum spacing or distance D. Coupling web  318  has a width to define distance D between members  312  and  314  of no more than about ¼ inch. Compressible members  312  and  314  is typically manufactured by casting or molding polymeric foam material, without use of a preform. Web connector  318  may be integrally molded together with compressible members  312  and  314 . Eyelets or loops,  320 ,  322 ,  324 ,  326  are anchored in the foam material of compressible members  312  and  314  and embedded therein during the molding process. Channels  358  and  360  may be bored by high speed drills after curing of the foam material. 
         [0068]    In general, use of a proprioception assist device  10 ,  110 ,  210 ,  310 ,  502  ( FIGS. 19 and 20 ) as described herein entails placing resiliently compressible members  12 ,  14 ;  112 ,  114 ;  312 ,  314 ;  212 ,  214 ;  504 ,  506 ; etc., against a back BCK or a user USR ( FIG. 7 ), so that the resiliently compressible members are disposed in parallel to the user&#39;s spine and on opposite sides of the spine. Where the compressible members  12 ,  14 ;  112 ,  114 ;  312 ,  314 ;  212 ,  214 ;  504 ,  506 ; etc., have a convex surface and a flat surface, the convex surface is placed against the user&#39;s back while the flat side engages a flat support surface, such as a seat back. 
         [0069]    In use of a wearable device  10 ,  110 ,  310 , the user sits at a desk hunched over a computer and once an hour leans back against the compressible tubes  12 ,  14 ; 
         [0070]      112 ,  114 ;  312 ,  314 ; and breathes and pulls the hand held bungees  52 ,  160 ,  352  forward to intensify the effect of stimulating the parasympathetic nervous system and release back tension. 
         [0071]      FIG. 7  particularly illustrates the use of a supine proprioception assist device  210  or  502  ( FIGS. 19 and 20 ). The USR is in a supine position and a generic compressible member  500  (about 40 inches long) is disposed against the user&#39;s back BCK. The user USR breathes into her or his back against the resiliently compressible members  212 ,  214  or  504 ,  506  so that the those members exert a traction like action on muscular tissues along the user&#39;s spine, providing proprioceptive feedback enhancing the user&#39;s respiration. Typically, the movement is a natural by-product of breathing exercises whereby the chest is alternately expanded and contracted, with the contact of the compressible members  212 ,  214 ;  504 ,  506  against the tissues flanking the spine providing the user USR with proprioceptive feedback. 
         [0072]    Where a fastening and user attachment assembly  16  or  116  is coupled to the resiliently compressible members  12 ,  14  or  112 ,  114 , the disposing of the resiliently compressible members against the user&#39;s back includes attaching the fastening and user attachment assembly  16  or  116  about the user&#39;s rib cage or thorax THX. Where the fastening and user attachment assembly  16 ,  116  includes an elongate tensile member  52 ,  160 , the attaching of the fastening and user attachment assembly to the user&#39;s thorax THX includes disposing the tensile member  52 ,  160  along the back side of the user USR. The method then further comprises attaching ends ( 54 ,  56 ;  162 , 164 ) of the tensile member  52 ,  160  to the user&#39;s hands HND and exerting tension on the elongate tensile member. 
         [0073]    A proprioception assist device  502  shown in  FIGS. 19 and 20  is particularly adapted for supine use and comprises two elongate resiliently compressible members  504  and  506  each approximately 40 inches in length and at least one coupling element such as a fabric strip  508  connected along longitudinal edges to a pair of casings  510  and  512  that contain compressible members  504  and  506 , respectively. Casings  510  and  512  together with coupling strip  508  hold compressible members  504  and  506  in parallel relation to one another and at a maximum distance from one another. The maximum spacing is preferably no more than approximately ¼ inch (between the closest surfaces of the compressible members) so that members  504  and  506  (and casings  510 ,  512 ) engage the user over the ribs but not on the shoulder blades. 
         [0074]    Compressible members  504  and  506  are preferably made of a polymeric foam material such as polyethylene (PE) or EVA foam and have at least partially cylindrical outer surfaces  514  and  516 . Proprioception assist device  502  further comprises a user attachment component in the form of a belt or strap  518  that may be provided with VELCRO type hook and loop fasteners  520  and  522  for securing the belt or strap tightly about a user&#39;s rib cage, preferably just south of the pectoral muscles or breasts. Belt or strap  518  is loosely and adjustably coupled to compressible members  504  and  506  via a strip  524  that is sewn or glued at its ends  526  and  528  to coupling strip  508  to form a passageway  530  traversed by belt or strap  518 . Belt or strap  518  extends behind the user during use of the device. The longitudinal position of belt or strap  518  relative to compressible members  504  and  506  may be adjusted to suit individual users by sliding the belt orthogonally relative to strips  524  and  508 . Strip  524  has a length sufficient to accommodate users of all sizes. 
         [0075]    Proprioception assist device  502  further comprises a head support/rest assembly  532  at one end of compressible member  504  and  506  for enabling or facilitating a user&#39;s pressing downward of the head HD ( FIG. 7 ) to provide for spinal traction and an enhancement of proprioception awareness. Head support  532  includes a resiliently compressible member  534  attached to compressible members  504  and  506  via an elastic loop or band  536  which is sewn or glued or otherwise attached to casings  510  and  512 . Compressible member  534  may be a segment of the same material as compressible elements  504 and  506  and covered in neoprene or another stretchy “warming” fabric. 
         [0076]    User USR of a supine device  210  or  502  lies on rollers or compressible members  212 ,  214  or  504 ,  506  and breathes into the rib wrap  518  while depressing the head rest  532  and pushing against an ankle restraint  540  to stimulate the parasympathetic nervous system and reduce cortisol (a hormone which prevents weight loss). This process will take approximately five minutes per day. The user USR may take his or her feet out of the restraint  540  and lengthen the legs one at a time and lift the arms overhead. Use of ankle restraint  540  intensifies the traction effect. Ankle restraint  540  may take the simple form of a loop that is connected to an end of device  502  opposite head support  532  and long enough to extends to the feet. 
         [0077]    As shown in  FIGS. 10-15 , proprioception assist device  310  may comprise a body member  402  which includes elongate semi-cylindrical resiliently compressible members  312  and  314  connected to one another via strip or flange  318 . Compressible members  312  and  314  are formed with respective planar through slots  404  and  406  which receive elongate flat inserts  408  ( FIG. 16-18 ). Inserts  408  are formed at opposite ends with eyelets or loops  410  and  412  that serve as eyelets or loops  320 ,  322 ,  324 ,  326  shown in  FIGS. 8 and 9 . 
         [0078]    At one end—at the lower left in FIG.  10 —through slots  404  and  406  have mouths or openings  414 ,  416  that are of the same cross-section as the major extent of slots  404  and  406 . At an opposite end—upper right in  FIG. 10 , through slots  404  and  406  are defined by beveled shoulders  418 ,  420  which result in mouths or openings  422  and  424  of reduced width. As shown in  FIGS. 16-18 , eyelet or loop  412  of each insert or plate  408  is separated from the body of the insert or plate by a pair of notches  426 ,  428  that receive beveled shoulders  418  or  420  to lock the respective eyelet-bearing insert  408  to the respective compressible members  312 ,  314 . 
         [0079]    Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. For instance, a “user attachment component” as that term is used herein may take any form that enables attachment of the feedback assist device to a user so that the elongate resiliently compressible members are maintained in substantial or approximate parallel relation to one another on opposite sides of the user&#39;s spine when the device is placed against the user&#39;s back and as the user engages in motion of the back in part against a restoring force exerted by the compressible members  12 ,  14  or  112 ,  114  or  212 ,  214  or  312 ,  314 . A user attachment component in a wearable version of the assist device may therefore take the form of a vest, or halter top, with appropriate reinforcement such as leather or canvas bands, to accommodate the stresses exerted by the flexible elastic members during an exercise routine. 
         [0080]    Where the user attachment component consists mainly of shoulder straps such as straps  40 ,  42 ;  148 ,  150 ;  328 ,  330 , those straps may be attached to the resiliently compressible members  12 ,  14 ;  112 ,  114 ;  312 ,  314  in any suitable way. For instance, the straps may cross one another. Each strap may be connected at one end to a top of one compressible member and at an opposite end to the bottom of the other compressible member. In the embodiment of  FIGS. 5 and 6 , shoulder straps may be provided where the straps pass through tubes  240 ,  241 , each strap extending from the top of one compressible member  212  or  214  to the bottom of the other compressible member  214  or  212 . In that case, one length of strap may extend through both tubes  240  and  242  and form the two shoulder straps. The straps may be provided with elastic sections or adjustable buckles for optimal fit. 
         [0081]    In addition, the device  210  of  FIGS. 5 and 6  may be provided with straps, cords or tubing (not shown) acting as shoulder straps. 
         [0082]    Compressible members  12 ,  14 ;  112 ,  114 ;  212 ,  214 ;  312 ,  314  have such a length that the device extends over at least part of the thoracic and optionally part of the lumbar and/or cervical regions of the spine. Preferably, however, where the user USR of the device has to assume a supine posture ( FIG. 7 ), compressible members  12 ,  14 ;  112 ,  114 ;  212 ,  214 ;  312 ,  314  preferably have a length of about 40 inches so that the device extends from the head down to the tailbone of the user. The distance between the middle of the skull, at a point somewhat above the ears, and the tail bone, is approximately 38-40 inches for the large majority of adults. 
         [0083]    Instead of a semi-cylindrical cross-section, compressible members  12 ,  14 ;  112 ,  114 ; and  312 ,  314  may have a cylindrical cross-section, like the compressible members  212 ,  214  shown in  FIGS. 5 and 6 . The various proprioceptive feedback devices disclosed herein, for instance, devices  10  and  210 , may be provided with spacers or buffer elements between the respective compressible members  12 ,  14  and  212 ,  214  to ensure a minimum spacing between the compressible members. 
         [0084]    Proprioception assist device  10  may also include dual chambers that receive the resiliently compressible members  12  and  14 , for purposes of housing the spinous processes. 
         [0085]    Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
