Abstract

• The tremulousness observed with voluntary muscle contraction in patients with chronic denervating illness has long been described but has been given misleading and confusing labels. The phenomenon is generally attributed to the nonsmooth contraction of a muscle populated by motor units decreased in number and enlarged. Contraction pseudotremor of chronic denervation may be a more appropriate label for this useful clinical sign.
