Impact Testing

Impact loading of the FlexRim was studied for a wide range of impact intensities.

The FlexRim was found to consistently reduce impact loading by 10%.

Propulsion Testing

In lab testing, wheelchair users pushed with both a standard pushrim and the FlexRim on a research treadmill. Grip muscle activity, oxygen demand and power generated were all measured during propulsion and compared across pushrims.

Results of the testing were:

• Users required 12% less grip force to push with the FlexRim.

• Overall grip exertion was reduced by 15%.

• On average users required 12% less oxygen to push with the FlexRim than with a standard pushrim.

• Users generated 13% more power when using the FlexRim.
