Method for Estimating Tensiomyography Parameters from Motion Capture Data

Tensiomyography is a muscle performance assessment technique that measures its mechanical responses. In this study, we explored the possibility of replacing traditional tensiomyography measurement systems with motion capture. The proposed method allows the measurement of multiple muscle points simultaneously while achieving measurements during a patient's movements. The results showed that approximately 5 mm error was achieved when estimating maximal muscle displacement, while time delay in muscle contraction and contraction time was assessed with up to 20 ms error. As confirmed by physicians, the introduced errors are within the acceptable margin and, thus, the obtained results are medically valid.
