Moreover, hybrid approaches that integrate functional electrical stimulation or spinal cord stimulation appear to provide additional benefits. For lower extremity rehabilitation, ambulatory exoskeletons such as ReWalk, Ekso, Indego, HAL, Rex, Arke, and HANK have been demonstrated to offer safe and feasible gait training, with reported improvements in walking independence, balance, and stride parameters, although enhancements in gait speed remain modest.
