Fig. 3From: HAL® exoskeleton training improves walking parameters and normalizes cortical excitability in primary somatosensory cortex in spinal cord injury patientsPaired-pulse suppression in spinal cord injury. The bars present mean amplitude ratios (A2s/A1) before and after the training period and of healthy controls. Error bars indicate standard error of the mean. * = significant p < 0.05.
