Certain features of the slow leg tremor observed in chronic alcoholic ataxia were established by electromyographic recordings. In standing (Romberg's test) the recordings from the flexor and extensor muscles of the feet showed a 3 Hz regular, alternating tremor of high intensity. The tremor activity was synchronous in the right and left legs. A similar slow tremor could also, in certain attitudes, be recorded from other muscle groups in the legs and, rarely, in the upper limbs.
