Abstract

In one example, we describe a device for Crutches and Sitting Device as an improvement of the basic crutch to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries, and who frequently require using crutches for mobility. Normally, the conventional crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. We have solved all these problems here. Many other different variations are shown here, as well, such as walkers and specially curved handles for better grip and less/no injury. Also, we show crutch support in sitting position that works as a simple and handy decompression system for herniated or bulged discs and injured/weak back muscles.
