Patent ID: 8523792

Claim:
A finger rehabilitative training device for use by a patient comprising: a base; a first arm platform assembly that is coupled to the base and includes a support surface for a first arm of the patient to be placed; a second arm platform assembly that is coupled to the base and includes a support surface for a second arm of the patient to be placed, wherein the first and second arm platform assemblies are disposed adjacent one another in a side-by-side manner; a first finger restrainer for being coupled to at least one finger of a non-affected hand of the patient; a second finger restrainer for being coupled to at least one finger of an affected hand of the patient; a first support that is fixed to the first arm platform assembly; a first cross bar that is pivotally attached to the first support at a pivot point and extends across at least a portion of the first and second arm platform assemblies; a first cable attached between the first finger restrainer and a first end portion of the first cross bar such that when the respective finger of the non-affected hand on which the first finger restrainer is coupled is moved by the patient, the first cross bar pivots about the first pivot point; a second cable attached between the second finger restrainer and a second end portion of the first cross bar such that when the first cross bar pivots in either a counterclockwise or clockwise direction, the first end portion pivots in one direction, while the second end portion pivots in an opposite direction resulting in synchronized movement between the at least one finger of each of the non-affected and affected hands of the patient in that the fingers of the left and right hands that are contained within the first and second finger restrainers, respectively, move together in a same direction; and a counter force mechanism that provides resistance and provides a return force that counters pivoting of the first cross bar and returns the first cross bar to a rest position, the counter force mechanism including a linkage that is connected between the second finger restrainer and a pivotable lever, the pivotable lever being attached to the base with a biasing member that generates the return force to: (1) return the lever to a rest position after the lever pivots upwards due to pivoting of the first cross bar, and (2) return the second finger restrainer to a rest position.
