1. A mobility assistance apparatus, comprising:
first and second frames positioned on left and right sides of a user;
a fixed arm coupled to the first and second frames; and
a harness coupled to the frames with an angled surface mostly contacting the ischial tuberosities and adapted to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand, walk or work on a working surface for an extended period without requiring the user's arms to hold the frame;
a wheel coupled to the first and second frames;
a brake coupled to the wheel to provide friction to the wheel when actuated; and
a tensioner coupled to the brake to adjust cable brake tension by hand without a tool.
