Abstract
An apparatus and method for measuring abduction strength of a patient's thumb. The apparatus includes a frame for receiving the patient's hand thereupon in a longitudinal direction, enabling the thumb of the patient to move freely upwardly and downwardly about the joint at the base of the thumb. A thumb engaging means is pivotally mounted to the frame for engaging the patient's thumb assuring the upward and downward movement thereof. The thumb engaging means is pivotal about a transverse axis. A force transducer means is mounted to the thumb engaging means for detecting the force transmitted between the thumb engaging means and the patient's thumb. The force transducer means produces an output representative of the detected force. A display means is provided for displaying the received output.
