Reciprocal inhibition of the H‐reflex in the forearm flexor muscles was studied in 11 patients with essential tremor and in 10 normal controls. Whereas patients and controls had a similar first, disynaptic phase of reciprocal inhibition, patients had a significantly reduced second phase. Patients with more severe functional impairment had more pronounced abnormalities of reciprocal inhibition. Abnormalities of reciprocal inhibition may play a role in the pathophysiology of essential tremor and probably arise from defective suprasegmental control. © 1998 John Wiley & Sons, Inc.
