The invention relates to a system and method for providing feedback to a user on his or her running style or running technique. The system employs a pressure sensitive surface to record a gait line of the center of pressure exerted by the user's foot on an underlying surface during a footstep period. In case of a fore or mid-foot landing the gait line may be observed to move backwards with respect to the sagittal plane. From a backwards-going gait line two time stamps are determined. The first timestamp T1 is the time that the foot strikes the ground. The second timestamp T2 is the time that the gait line reaches the most backward position. From the time difference between these two timestamps a loading time dT is determined. The reactivity of the running style describes the viscoelastic behavior of the muscle-tendon unit and may be calculated as a function of this loading time and / or the distance moved by the centre of pressure backwards towards the heel. Correspondingly, a feedback signal may be provided to the user about his running reactivity.

A flexor tendon repair device has a sheet of mesh material of rectangular shape with four edges: two longitudinal edges and two lateral edges perpendicular to the longitudinal edges. Each pair of edges is mutually parallel and spaced apart. Each edge is also folded inwardly for two smooth edges upon which the healing tendon rests and two smooth edges where the sheet mutually joins. Along with the sheet, the invention includes sutures, typically doubled, and one at each lateral edge. The lateral edges generally support the healing tendon while the sheet wraps around the tendon with the longitudinal edges generally parallel to the length of the tendon. A surgeon, during use of the invention, tightens each suture along the longitudinal edges, closing the device, and then upon the laterals to tie the suture. Upon tying, the mesh attains an ovoid shape similar to the natural cross section of a tendon.

An anchor for fixing a ligament or tendon replacement in a bore formed in a bone has two parts. A first partially cylindrical part has a semi-circular bore therethrough extending along an axis. The bore tapers conically inwardly with respect to the axis from a larger radius at a first end to a smaller radius at second end. The outer surface of the partially cylindrical part is spaced at a constant radius from the axis between the first and second ends. The first and second parts have side walls formed between the bore and the outer surface which walls extend along a plane which forms an angle with respect to the central axis. When the two parts are engaged along their side wails and slide with respect to the axis the outer diameter of the two parts enlarges.

A handheld resistance exercise device is contemplated for exercise, rehabilitation, warm-up and the like, which provides resistance to muscles, tendons, joints, and fasciae in the upper body and lower back as it is actuated by a user standing a distance away from a vertical surface that is engaged with the device. Actuation thereof by the user in performing various exercise protocols provides stability for one or more muscles of the hand, elbow, shoulder girdle, shoulder blade, rib cage, as well as the inner core muscles, while also providing improved mobility for one or more of the wrist, forearm, elbow, shoulder joint, and muscles that rotate and bend the spine sideways.

A functional exercise glove includes a dorsal-side layer having in-plane resistance to stretch in the longitudinal direction of the glove that is greater than its in-plane resistance to stretch transverse to the longitudinal direction. At least one fingertip member transfers an extension / flexion force from a user's finger to the dorsal-side layer upon flexion of the finger. The glove is configured to react the extension / flexion force from the dorsal-side layer into at least one of the heel of the user's hand or the user's wrist. The dorsal-side layer resists extension from flexion of the fingers thereby working finger, hand, wrist, forearm muscles, tendons, ligaments, bones, and nerves specific to natural movement patterns. The exercise glove can be used during a job function, regular activity, and while playing a sport like golf, tennis, etc.

A system and method of knee-ACL support breeches for supporting the knees against non-contact anterior cruciate ligament (ACL) injuries, without interfering in desired movement, by resisting anterior translation of the proximal end of the tibia, thereby reducing stress on the ACL and other knee components. A pair of calibrated-elastic bands are attached at one end to a belt about the waist and at the other end to a strap around each lower knee. The calibrated-elastic bands are incorporated into a pair of breeches or pants which hold the bands tightly against the buttocks and backs of the thighs.
