摘要： An apparatus may be employed for determining the relaxation rate of a muscle which has been caused to contract in response to an electrical stimulus. The relaxation rate may be used in evaluating a person's nutritional status. The apparatus has support for supporting the forearm and wrist of a person in a palm-up position with the wrist extended. An electrical stimulus is applied to the person's ulnar nerve, and the force exerted upon a load cell by the person's thumb is measured. A computer is employed for receiving, storing, plotting and analyzing the force data collected by a transducer.
