A person with lower limb disability may have to use a wheel chair for the entire life. In a conventional wheelchair the user spends time in a seated position all the time. This constraint gives rise to many physical as well as mental health related issues such as sore body, building of pressure points leading to pressure sores, lowered blood circulation, and dependence on other people for basic needs. One solution to this problem is to provide mechanisms in the wheel-chair to assist the person to stand.
