It is recognized that the locomotor-like EMG activity of the lower leg muscles can be observed by imposing passive stepping movement in persons with spinal cord injury (SCI). In the present study, we observed the EMG activities in 22 able bodied, 15 stroke, and 8 complete SCI subjects during passive locomotive leg motions. Although the imposed leg motion is almost identical, each group shows different character of the EMG activity. Namely, some able bodied subject showed no EMG activity or larger extent of the fluctuation of the EMG magnitude which has strong relationship between each of limbs. On the other hand, there are less fluctuation in SCI group, and less relationship between right and left limbs in stroke group. Given the pathology of the SCI and stroke patients, such differences can attribute to the connection to the higher nervous center.
