Abstract

A method for analyzing muscle function and comprising the steps of: forming a plurality of electrodes each having a pair of elongated, substantially parallel detection surfaces; locating in a human body a muscle activatable to product a given torque; fixing each of the electrodes over a different muscle in the group with the detection surfaces oriented substantially perpendicular to muscle fiber direction in the muscle; activating each of the different muscles to generate therein myoelectric signals detected by the electrodes; and processing the myoelectric signals detected by the electrodes. Myoelectric signal quality is enhanced by orienting the detection surfaces peripendicular to the direction of muscle fiber.
