Abstract

Flat foot which is also known as Pes Planus is one of the types of problematic foot. One of the way to treat flat foot problem is by using an orthotic insole as to provide support, correct the deformities and improve the movement of joints and limbs. The customised orthotic insole can fit the patient’s feet perfectly and perform better than off – the – shelf insoles that already available in the market. A mass production is not suitable for the orthotic insole production due to the large range of dimension characteristic for each individual. Thus, another approach is necessary to be considered by implementing additive manufacturing technology to produce the customised orthotic insole. The purpose of this study is to determine the efficacy of customised TPU orthotic insole using EMG testing, to identify the muscle fatigue during repetitive work and to interpret the potential influence on muscle fatigue and suggest optimisation. The efficacy of customised TPU orthotic insole is determined by conducting EMG testing on subject who suffers from flat feet. The experiment is repeated three times and the data is recorded in bar graph. The muscles fatigue with insole and without insole is compared under three different tasks which are walking, running and stair climbing. By analysing the bar graph, the potential external influences for the muscles fatigue is evaluated. The EMG testing proved that the muscles fatigue can be reduce by using customised TPU orthotic insole. The varying assigned tasks affected the muscles fatigue differently depending on some factors. The customised TPU orthotic insole offers a support, correction for deformities on the foot and reduction of muscles fatigue.
