OBJECTIVE: To determine whether a primary fitness program utilizing arm crank ergometry would cause increased shoulder pain in persons with spinal cord injury (SCI).
DESIGN: Cohort study.
SETTING: Clinical research center.
PARTICIPANTS: People (N=23) with chronic SCI (>1 y) who were participating in a weight loss study to compare the effectiveness of diet only (1000 kcal/d for 12 wk) versus diet with arm crank ergometry (1000 kcal/d and arm crank ergometry 3 times a week for 12 wk).
INTERVENTION: Arm crank ergometry.
MAIN OUTCOME MEASURE: Changes in shoulder pain intensity using the Wheelchair User's Shoulder Pain Index (WUSPI).
RESULTS: After adjusting for baseline scores, there was no significant difference between the 2 groups on postintervention WUSPI scores (F(1,20)=.85, P=.37, partial eta2=.04). The strength of the relationship between group assignment (diet only vs diet and arm crank ergometry) and final WUSPI score was weak, as assessed by a partial eta2, with group assignment accounting for 4% of the variance on the WUSPI. The adjusted means were lower in the diet and arm crank ergometry group (mean, 7.84) than in the diet only group (mean, 12.22); however, these differences did not appear to be clinically significant.
CONCLUSIONS: A primary fitness program using arm crank ergometry does not increase shoulder pain in people with SCI who use wheelchairs. Further investigation with a larger group and what constitutes clinically significant changes on the WUSPI is warranted to confirm our results.
