The purpose of this study is to examine motor ability of infants using by surface electromyography (EMG). Subjects were 9 healthy infants. Subjects were divided to two groups (high ability group and low ability group) based on performance test. Surface EMG was recorded from calf muscles in infants during jumping. Integrated EMG was calculated as index of muscle activation. EMG discharges were seen not only during jumping, but also during standing at rest in low ability group, indicating the muscle activation during standing at rest. The EMG discharges from tibialis anterior and gastrocnemius corresponding to motion were seen during jumping in high ability group. The integrated EMGs were larger in the high ability group than in the low ability group during jumping. The integrated EMGs were smaller in the high ability group than in the low ability group during standing at rest. These results suggest that infants in the high ability group can achieve motor task according to regulate the muscle output, and that surface EMGs are useful as the noninvasive index of motor performance in infants.
