Abstract

OBJECTIVES:

To compare the energy efficiency of straight-line wheeling using Spinergy wheels as compared with standard steel-spoke wheels, and to assess the 2 wheels in terms of user comfort and wheeling preference during a wheeling course with multiple turns and surfaces.

DESIGN:

Nonblinded randomized crossover trial.

SETTING:

Rehabilitation center.

PARTICIPANTS:

Twenty persons with paraplegia (neurologic level T6 and below).

INTERVENTION:

Wheeling a straight line and obstacle course with Spinergy or standard spoke wheelchair wheels.

MAIN OUTCOME MEASURES:

Velocity and Physiological Cost Index (PCI) while wheeling over ground at a self-selected pace, and the User Preference Questionnaire after wheeling an obstacle course, using Spinergy or standard spoke wheelchair wheels.

RESULTS:

There was no significant difference in wheeling energy efficiency between the Spinergy and the steel-spoke wheels as measured by PCI ( P =.975). When rated for overall comfort, the Spinergy wheels were preferred over steel-spoke wheels ( P =.002).

CONCLUSIONS:

Spinergy wheels provided a more comfortable ride, but did not differ from standard steel-spoked wheels in terms of energy efficiency. The increased comfort may have important implications in patient management of pain and spasticity.
