The goals of this project are to 1)determine the responsiveness of the 6 Minute Push Test
(6MPT) to change accompanying an intervention known to increase peak volume of oxygen (VO2)
in persons with spinal cord injury (SCI) and 2) explore the relationship between 6MPT
distance and measures of handicap, wheelchair satisfaction, depression, and self-reported
avoidance of environmental features.

The 6 minute walk test is a widely used assessment of aerobic capacity, function, and
functional change in the ambulatory population. A similar clinical and research outcome
instrument that is responsive to changes in aerobic capacity and function are lacking for
persons with spinal cord injury (SCI). A 6 minute push test, adapted from the 6 minute walk
test may fill the void. The primary aim of this project is to assess if distance traveled in
6 minutes of wheelchair propulsion changes after an increase in aerobic capacity. We
hypothesize that participants will push farther in 6 minutes after their aerobic capacity
increases. The secondary aim is to explore the correlation between 6MPT distance and
handicap, depression, wheelchair satisfaction, and self-reported avoidance of environmental
features. We hypothesize increasing 6MPTdistance will be correlated with decreasing
depression, decreasing handicap, decreasing self-reported avoidance of environmental
features, and increasing wheelchair satisfaction. This is a low risk, high benefit study.
