The purpose of this study was to investigate the controllability of several pursuit movements of the arm muscles. Three subjects in a sitting position were studied for elbow flextion and extension. Three wave forms (sinusoidal, sawtooth and rectangular) on VDT were followed by the subjects, and 5 work loads were given at 0.3 Hz frequency.The following results were obtained.1.There was phasic delay in the order : sinusoidal (-10°),sawtooth (-15°),rectangular (-20°).2.An overshoot phenomenon was observed for each wave form during the flexion phase at a work load under 10% of the maximum strength.At a work load of over 10% of the maximum strength,an undeshoot phenomenon was observed.3.With regrd to controllability,the error area increased in the order : sinusoidal (4〜7%),sawtooth (6〜12%),rectangular (15〜25%).4.There was a significantly smaller EMG output from antagonists during both the flexion and extension phases at workloads of 4 and 8 kg.
