Patent ID: 8678984

Claim:
An exercise and therapy apparatus for use on or off a support surface by a user having an arm, flexor and extensor muscle groups, a forearm having a top and bottom, a wrist, a shoulder, an elbow and a hand having a palm and fingers, comprising: a base having a concave wrist support portion that support the user's wrist, said base being arranged and constructed to engage the bottom of the forearm at the user's wrist, said base, when resting on said support surface being of sufficient height to allow both linear and angular wrist movement without the hand contacting said support surface; a push bar pivotally connected to said wrist support portion, said push bar sprung and biased towards a resting neutral position wherein said push bar can be moved through a range of positions by hand movement to a selected position, said push bar movable to be substantially perpendicular in both directions to the orientation of the user's forearm for stretching the wrist beyond the wrist's natural extension range, said push bar's movement being adjustable for providing either a constant or gradual resistance to movement by said user's hand from said neutral position; a tension adjustor for changing the amount of force necessary to move said push bar by said hand's pushing or pulling from said neutral position both in an upwards and downward direction for exercising said flexor and extensor muscle groups, said tension adjustor being able to lock said push bar in a selected position; and further including a plurality of individually sprung finger cams of selected lengths extending from said push bar for exercising individual or multiple fingers, said finger cams can be rotated or locked in any desired combination with the spring tension of each finger cam being independently adjustable in resistance to movement.
