Spasms of amputation stumps.

Two patients are presented with muscle spasms in an amputation stump. Neither patient experienced neuropathic pain nor phantom sensations, though phantom sensory phenomena, severe pain, and lack of response to treatment is characteristic of reported cases. One patient, a 75 year old man, has had myoclonic activity of the stump for more than two years, and the other, a 79 year old woman, recovered spontaneously after three months and is symptom free after a one year follow up. We emphasise the lack of association with pain and the need to consider spontaneous improvement when therapy is evaluated.
