Optimization in measurement of MVC and active stiffness in wrist using the quick release method

다국어 초록 (Multilingual Abstract)

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