Abstract: | The quick release method was used for measurement of Biomechanical parameters in the wrist joints. Wrist joint was previously studied in many researches for its biomechanical characteristics. However, more automation in measurement process has been discussed. In this research, a new test rig with a specified control unit was fabricated. Measurement of parameters in few seconds after the release was considered in the design of the new test rig. Based on reliability tests performed, the fabricated test rig showed firmly reliable measurements for maximum voluntary contraction, and active stiffness. These were true for both cases of left and right wrists during flexion and extension. |
