There is only antidotal literature that the choice of seating equipment and wheelchair wheels play an important part in the management of spasticity and perceived comfort by decreasing the amount of whole body vibration felt by the individual with a SCI when traversing over rough surfaces such as bumps in sidewalks or rumpled carpets (Vorrick et al., 2008).
Spinergy wheels have a triple-cavity rim, alloy hubs with one piece construction and carbon-fiber spokes that originate from the hub (reverse spoking) and claim to absorb 25% more road shock than conventional steel- spoked wheels (Spinergy, Inc. San Diego, California). In the study completed by Vorrick et al. (2008), the study reported no significant differences in self-reported spasticity or vibration (measured by accelerometers) when examining the effect of two different wheel choices, Spinergy wheels verses standard steel-spoked wheels.
There is level 2 evidence (from one randomized controlled trial; Vorrink et al. 2008) that the use of Spinergy wheels verses standard steel-spoked wheels was no more effective in reducing spasticity by absorbing vibration forces when wheeling.
- There is insufficient evidence to determine if Spinergy wheels are more effective in reducing spasticity by absorbing vibration forces when wheeling.
