The Computer Modelling of the Human Gait Cycle for the Determination of Pressure Distribution and Ground Reaction Force Using a Below Knee Sockets

In this research, many composite configurations were presented employing perlon, kevlar, and carbon fibres in addition to the kenaf fibres, which were used to create the original below-knee (B.K.) prosthesis. These modifications were made for convenience and to lengthen the useful life of our prosthesis. The study used a layered experimental design, with some layers containing kenaf and others without. The ideal strength-to-weight ratio (E/ρ) and the desired modulus of elasticity were sought, together with the effective lamination employed in the production of sockets. They prepared the socket produced from natural kenaf fibres and analyzed its performance throughout the gait cycle comprising the experimental phase. A kenaf prosthetic socket was provided to a 58-year-old man who lost his right Leg to diabetes and weighed 80 kg. This socket took group D-f. Tests of the ground reaction force (G.R.F.) showed that the difference between the stance and swing phases did not exceed (−5.3%), or 5.3% improvement over a different instance, signifying a 20.8% improvement.
