Wrist driven flexor hinge orthosis (WDFHO) linkage movements were analyzed graphically for existing kit form orthoses and modified orthoses. The graphical analysis indicated improved function by increased torque and resultant pinch force in modified orthoses. A geometric solution to pivot point location which will allow clinicians and orthotists to properly locate the linkage pivot points for WDFHOs was developed. Improved function was documented in 5 orthoses converted from kit form linkages to modified linkages.
