Rehabilitation is increasingly benefiting from developments in medical robotics and bio-mechatronics. The growing demand for rehabilitation, mostly due to the rising number of accident injuries and population ageing, also contributes to the need for more optimized treatment methods. To this end, exoskeletons which are wearable robots are designed to enable spinal cord injury (SCI) patients to walk and to improve the treatment process. Robots can equip physiotherapists with detailed data regarding the rate of improvement, and this quantitative feedback will motivate the patient and help the physiotherapist to determine the most effective treatment.
