Abstract: A system includes a first device having a handle, a head coupled to the handle, a bumper supported by a first end of the head and adapted to be used to strike a patient tendon, a force sensor coupled to the bumper and adapted to generate force data in response to force encountered by the bumper and to generate force data, a first accelerometer coupled to generate head acceleration data in response to movement of the head, and first circuitry to capture the force data and acceleration data. The system may further include second device having a housing adapted to be coupled to the patient limb, a second accelerometer supported by the housing to generate limb acceleration data, and second circuitry to capture the acceleration data.

Abstract: A shoulder harness recoil restraint clip comprising a clip member having first and second engagement portions flexibly connected by a flex hinge that allows the first and second engagement portions to rotate in a manner such that a first surface of the first engagement portion covered with a first plurality of gripping ridges is rotatable into a position contacting a second surface of the second engagement portion covered with a second plurality of gripping ridges. The first and second engagement portions are lockable to a section of shoulder harness strap material adjacent the recoil mechanism by a locking tab positionable with a locking tab receiving channel formed through one of the engagement portions. The locking tab is held in place by locking tab ridges positioned on either side of a locking tab receiving channel. The locking tab has an engagement head adapted to seat between adjacent locking ridges.
