Purpose: A novel exoskeleton with use four-bar linkage mechanisms for hand rehabilitation was recently
developed by Marmara University Mechatronics-Rehab-Lab researchers. The aim of our study is to asses the
usability of the designed exoskeleton for hand rehabilitation.
Methods: In-dept interviews with focus group (the designer of device, one experienced hand therapist and one
physiotherapist researcher who is working technology rehab) were conducted. Our open-ended interview
queries with participants encouraged them to describe their experience while designing the device or usability
of the prototype exoskeleton for hand rehabilitation. The focus group discussed the ten topics (mechanical
design, passive and active joint angle, tendon gliding mechanism, passive motion, active motion, resistive
motion, advantages and disadvantages for clinical uses etc.). The focus group members use the exoskeleton
while interview was going on. We took notes and audiotaped interviews from the focus group. After in-dept
interview we coded the major topics.
Results: Compared to others, a simple mechanism is designed and produced suitable for the hands bio
dynamics. The physiotherapists specified that the linkage mechanism is a great idea for flexor tendon gliding
after flexor tendon injury repair for clinical hand rehabilitation. A minimal traction error found while doing active
Conclusions: A novel exoskeleton with use four-bar linkage mechanisms useful for hand rehabilitation for flexor
tendon injuries and has a great advantage for supporting hand exercisers at home. Only some ergonomic
designs needed before developing last version of device.
