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.
