Abstract
Patients who had previously undergone amputation of the arm (n = 2) or leg (n = 2) were treated with botulinum toxin type B injections at several trigger points of their stump musculature. We administered a total dose of 2500 IU of botulinum toxin type B (Neurobloc, Elan Pharma, Munich, Germany) to the arm amputation stumps, 5000 IU for one amputation of the lower leg, and 2500 IU to the other lower leg amputation of a patient with a very low baseline body weight. Two patients reported that the injection was very painful. All patients experienced a reduction in stump pain, which lasted for many weeks. Other reports included a reduction in the frequency of pain attacks, cessation of "balloon feelings," improvement in stump allodynia, and decreased occurrence of involuntary stump movements. In addition, quality of sleep at night significantly improved in one patient. Botulinum toxin type B can therefore be regarded as a new treatment option for possible improvements in the rehabilitation of amputees.
