DETAILED DESCRIPTION

(21) 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.

(22) 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.

(23) 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's back so that the compressible members are parallel to the user's spine—preferably the thoracic region of the spine—and on opposites thereof.

(24) 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'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.

(25) 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'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.

(26) 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.

(27) 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.

(28) 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's back so that the compressible members are parallel to the user'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'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's spinal column.

(29) 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'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.

(30) 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.

(31) 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.

(32) 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.

(33) 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.

(34) 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.

(35) 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.

(36) 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.

(37) 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.

(38) 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'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's back while the flat side engages a flat support surface, such as a seat back.

(39) 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; 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.

(40) 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'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's spine, providing proprioceptive feedback enhancing the user'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.

(41) 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's back includes attaching the fastening and user attachment assembly 16 or 116 about the user'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'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's hands HND and exerting tension on the elongate tensile member.

(42) 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.

(43) 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'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.

(44) Proprioception assist device 502 further comprises a head support/rest assembly 532 at one end of compressible members 504 and 506 for enabling or facilitating a user'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. Compressible member 534 is positioned laterally to and in contact with curved or arcuate sidewall surfaces compressible members 504 and 506. Compressible member 534 extends across and to the side of compressible members 504 and 506 at one end thereof.

(45) 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.

(46) 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.

(47) 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.

(48) 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's spine when the device is placed against the user'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.

(49) 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.

(50) In addition, the device 210 of FIGS. 5 and 6 may be provided with straps, cords or tubing (not shown) acting as shoulder straps.

(51) 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.

(52) 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.

(53) 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.

(54) 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.
