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.
