Simplified, low cost below-knee prosthesis

Simplified, low cost below-knee prosthesis.

Problems are encountered in using standard prostheses in developing countries, especially when the prostheses need repair and the amputees cannot come back to the workshop. Very simple, low cost and durable prostheses can solve this problem. The solution described has worked well with villagers in some rural areas of Thailand, where the inexpensive prosthesis permits walking bare-foot and throu...

Prosthesis-free solution for below-knee amputations.

The Ilizarov fixator can be used as a bone regenerator to correct limb-length discrepancies in patients who require limb lengthening.A 17-year-old man presented with 12 cm of left lower-limb shortening and amputation at the left mid-forefoot region, which was the result of severe burns of the left lower limb at 2 years of age. The burns damaged the distal femoral, proximal, and distal tibial ph...

Dynamics of a Running Below-Knee Prosthesis Compared to Those of a Normal Subject

The normal human running has been simulated by two-dimensional biped model with 7 segments. Series of normal running experiments were performed and data of ground reaction forces measured by force plate was analyzed and was fitted to some Fourier series. The model is capable to simulate running for different ages and weights at different running speeds. A proportional derivative control algorit...

Dynamic testing of below-knee prosthesis: assembly and components.

Prosthetic assemblies for lower limb amputees are highly engineered and consist of several components each with its own failure mechanism. This paper describes the dynamic testing of HDPE rotational moulded sockets in a specially designed machine which mimics normal gait. Thus the components are subjected to all main loadings occurring during a stride such as axial loading and A-P bending about...
