Abstract
A pelvic support and walking assistance device is disclosed which includes a trunk support member and a thigh lifting member coupled to each other at a pivot joint positioned opposite a hip joint of a user. The device functions to prevent pelvic sway. With a spring coupled with said pivot joint, the device further provides a thigh lifting torque to partially compensate for proximal leg weakness. The spring assistance pivot device includes a winding device that can be adjusted in use for varying forward torque for varying situations.
