About

Adaptive gait assessements will be evaluated as a potential new marker for tracking locomotor recovery throughout rehabilitation of spinal cord injury subjects. To this end, controls, subacute and chronic patients will be assessed at two timepoints with 3 month standard rehabilitation inbetween. The specific assessments will require the participant to acitvely modulate their gait pattern to fullfill specific task constraints. Their performance will be assessed via 3D kinematics, kinetics and EMG and these measures will be used to describe the adaptive capacity that the patient retains. Sensitivity and specificity of these markers will be determined. With more sensitive descriptors of gait function and quality, locomotor rehabilitation for SCI can be better designed and smaller effects can be accurately measured.
