Hand held electrical impedance myography (EIM) of hand muscles was used to test muscle atrophy after traumatic peripheral nerve injury. EIM reactance and phase values of the affected muscles were consistently lower than those of healthy muscles. Severity of peripheral nerve injury determines the extent of muscle atrophy.
