Outline of Final Research Achievements

Although human infantile movement patterns have been well characterized, little is known about the characteristics of motor output and sensory feedback during their movements. Firstly, we developed multi-channel surface electromyogram electrode made from silicon material for delicate skin of human neonate/infant. Secondly, we combined the measured kinematics and infantile musculoskeletal model, and found that calculated pair-wise correlations of muscle lengths between each two muscles were higher in infant than neonate, especially in upper and lower limbs muscle.
