ABSTRACT:
Apparatus (1') for measurement of both the grip strength of a person's hand and pinch strength of two digits of the hand comprises two parallel grip handles (2', 3') extending at right angles from a third member (4'). Handle (3') is rigidly fixed to third member (4') and has two pairs of strain gauges mounted thereon to measure the force applied to the handles irrespective of where that force is applied. Handle (2') is adjustable with respect to handle (3') to alter the distance between the two handles, and the ends of the handles terminate in flat portions (6', 7') to be used for measurement of pinch strength.
