Introduction of a functional below-elbow prosthesis which assumes elbow-joint movement as a power source

Abstract

A purpose of this thesis is to introduce a functional below-elbow prosthesis which does not use a harness. The problem with this functional arm in our examination process was the control of the terminal device and suspension of the functional arm. The control of the terminal device was improved by four phases of lever-type locking mechanisms. The suspension of the functional arm was improved by using a silicone liner. The improved functional arm was used in activities of daily living by a patient for 21 months and led to the improvement of a damaged part. Finally, the functional arm that we made was approved as an exceptional prosthesis in Okayama and was a candidate for the public funding.
