ABSTRACT:
There is disclosed an orthotic device adapted for use with a hand of a user to restore grasping function. The device includes a finger retaining member and thumb support. The finger retaining member is pivotally moveable from a first open or non-grasping position when the finger retaining member is spaced from the thumb support, to a second position where the two are adjacent. The device achieves this function by incorporating a suitable shape memory alloy suitably associated with the finger retaining member and thumb support.
