Long-term effects of partial limb amputation in man.

Ten patients with amputation of part of one arm have been studied electrophysiologically. In each patient the ulnar nerve was stimulated electrically in the amputation stump and at a corresponding level in the intact limb. Control observations were also made on 15 normal subject. In the partially-amputated (PA) limbs the amplitudes of the centripetal ulnar nerve compound action potentials, after maximal stimulation of fast-conducting fibres, …
