Ergonomics Leg Prosthetic Redesign Using An Anthropometric Approach

Abstract

There are several factors and conditions that need attention such as patient health, different sizes and components used in manufacturing leg prosthetic. During this time, Mr.X has used prosthetic leg but with an inappropriate size, the prosthetic leg is longer than the original size of MR.X's foot so that it results in discomfort when use until complaints of injury. One ergonomic approach that can be applied in the design of an equipment to produce optimal products according to the dimensions of the user's body is anthropometry. Measurement of anthropometric data according to the body dimensions of Mr.X for the redesign of prosthetic leg by paying attention to the work activities of the user including the body dimension of D6 of 87.5 cm, D7 of 64 cm, D11 of 38 cm, D12 of 11.8 cm, D13 of 39 cm, D14 of 37 cm, D15 is 52 cm,D16 of 40.2 cm, D30 is 20.5 cm and D31 of 8 cm. In the trial redesign of Leg Prosthetic obtained a better sense of comfort, lighter than the previous prosthetic leg, and no need to use tools in the form of sticks when walking.
