Spinal cord injury (SCI), damage to spinal cord, influences the ability of the subjects to stand and walk. Moreover, they have some problems such as osteoporosis, muscle spasm, joint contracture and bowel and bladder function. These subjects use various orthoses and undergo different rehabilitation programmes to restore their ability. It is controversial whether use of aforementioned methods improves the physiological health of SCI individuals and improves their ability to ambulate or not. Therefore, the aim of this review was to investigate the effectiveness of assistive devices to restore their physiological health and their functional ability in patients with SCI.
