1. Neurophysiology has shown that both subclinical 1 Myers;B, D.;Arch Phys Med Rehabil; grip function in polymyositis and abnormal muscular fatigability are common in rheumatoid arthritis.8 ' Fatigue in itself is an index of muscle training and is likely to be prolonged in muscular wasting, whether due to primary disease or secondary changes following disuse and' reflex inhibition. In short term studies there is therefore likely to be little change in this variable, and on the whole the results of this study patients with rheumatoid arthritis,1980
