Anthropometry of Wheeled Mobility Project: Final Report

3.3.9 Toe Clearance Depth, minimum

Toe clearance depths for the standards range from 150 mm (6 in.) in the U.S. to 230 mm (9 in.) in Canada (Figure 3‒9). None of the comparison studies used for this report provided anthropometric information about toe clearance depth. While the Canadian standard accommodates over 85% of our WhMD users, the U.S. standard accommodates fewer than 50% of our sample.

* Indicates data plotted in the graph.

** Does not include individuals with a below-knee right leg amputation (n=10) or with the right leg constrained in fully extended position (n=3) such as in an orthopedic cast.
