Nerve or motor point block with 7% phenol solutions for the relief of the spasticity that had resulted from a number of causes was tried 238 times in 72 patients. 37 patients were cerebral palsy, which was most common, 11 patients were cerebrovascular accident or traumatic brain injury, 11 patients were spinal cord injury, 3 patients were tumor of central nervous system. Most common injection sites were biceps brachii and pronator teres muscles in upper extremity for the relief of flexion synergy in the cerebrovascular accidents patients, and medial head of gatrocnemius and tibialis posterior muscles in the lower extremity for the relief of equinovarus deformity in spastic diplegia type cerebral palsy patients. Total dose injected in each patient was 0.8 to 20.2cc(average 6.4±4.1cc) and which was far below the toxic dosage. We have not encountered any serious side effects except for few local induration or pain and mild dizziness. Ease, simplicity, safety, therapeutic benefits, and economic advantages of nerve or motor point block with 7% phenol solutions warrant its more widespread use.
