Abstract
A piston finger technique (PFT) was developed for restoring the motor function of chronic plegic fingers, with good treatment outcomes, including reduced spasticity and improved muscle shortening. Before developing a piston finger device (PFD) simulating the PFT, we analyzed the PFT by using a motion capture system. The motion of a chronic plegic index finger was investigated after administering two types of PFT-based treatment. The ranges of motion of the proximal interphalangeal and metacarpophalangeal joints of the index finger, and the vibration width and frequency during treatment were measured. These results will be useful for developing a PFD.
