Biomechanical evaluation of wrist-driven flexor hinge orthosis in persons with spinal cord injury

Yeoun-Seung Kang, MD, PhD, CPO, et al.

A wrist-driven flexor hinge orthosis (WDFHO) is a device used to restore hand function in persons with paralyzed hands. The device is inexpensive and easy to use by persons with impaired hand function caused by spinal cord injury. We analyzed the effectiveness of a WDFHO in persons with spinal cord injury. For this, we introduced mathematical equations to model operating principles and evaluated the effectiveness of the WDFHO. Our results confirmed that pinch force significantly improved after using the WDFHO. In addition, we found that the device requires better alignment for persons with greater wrist strength.
