Prosthetics Suffering Limb Loss doesn't have to be painful.  Modern dayprosthesis devices can help return life to normal.


Prosthetic devices are used to replace missing extremities, such as arms , hands, fingers, legs, feet and even toes.

There are several levels of lower limb amputation, including partial foot, ankle disarticulation, transtibial (below the knee), knee disarticulation, transfemoral (above the knee), and hip disarticulation. The most common are transtibial (mid-calf) and transfemoral (mid-thigh). The basic components of these lower limb prostheses are the foot-ankle assembly, shank, socket, and suspension system.

or assists the musculo-skeletal system particularly the

Lower Extremity

Orthotics are known to help improve balance and proprioception, enhance muscle function, reduce leg length inequality, lower extremity overuse injury, and help patients with sacroiliac syndrome, heel spurs, low back pain, patellofemoral pain syndrome and a host of other conditions. A new study in the Journal of Manipulative and Physiological Therapeutics attempted to determine if orthotics could create positive structural skeletal changes in the foot. The results showed that the custom made orthotics not only improved biomechanical support, but were also comfortable and effective.
