In this paper, a simple simulation is discussed for verifying the adjustment techniques of the Bowden cable system on a transhumeral prosthesis. The prosthetic arm is modeled as a 2-D two-joint link model with a cable to relate the shoulder and elbow joint movements. By solving the equation and applying the numeric values of Japanese male adult's arm dimensions, the simulation results were computed. The results of the sequential procedure in the problem solving strategies, which are provided in the prosthetics text books, were reasonable and showed that moving the lift bar (Elbow Flexion Attachment) and base plate in the stated direction are effective to gain better performance of the cable system. However, the simulation showed more successful solutions to instantly gaining better performance. Further study will be needed to confirm the simulation result and correspond to force problem in the adjustment of the cable control system.
