Sensorimotor Control During Postural Transitions in CP

Subjects will be asked to perform postural transitions like sit to stand, gait initiation, sit to walk and Timed up and the Go (TUG) functional test. This will entail a subsensory electrical signal with a white noise frequency distribution. Proprioceptive SR electrical stimulation will be delivered by BIOPAC Systems, Inc. stimulators that are current limited to deliver less than 10 milli ampere of current. Electrical stimulation will be delivered to muscles and joints along the legs and hips. The stimulation intensity will be very low, below the sensory threshold of the participant.
