Diabetic amyotrophy: a follow-up study.

A clinical follow-up study of 12 patients with diabetic amyotrophy is reported. Re-examination after an interval indicated that improvement had occurred in all but one instance, and had been maintained over an average follow-up period of four and a half years. Improvement in the neurological syndrome appeared to follow improvement in diabetic control or institution of treatment in those whose diabetes had not previously been diagnosed.Seven patients made a good functional recovery, three no longer having any muscular weakness. Five showed significant residual disability.
