Abstract
STUDY DESIGN
Retrospective chart review.
OBJECTIVES
To determine the prevalence of fatigue in an outpatient spinal cord injury population and to examine the clinical variables contributing to that fatigue.
SETTING
GF Strong Rehabilitation Centre, Vancouver, British Columbia, Canada.
METHODS
Medical charts of 76 individuals admitted to the GF Strong Outpatient SCI Program between December 2004 and December 2005 were reviewed. Data collected included information on clinical characteristics, demographics and Fatigue Severity Scale (FSS) scores. Multivariable analysis was completed to determine the independent association between these variables and fatigue severity.
RESULTS
A total of 57% (95% confidence interval (CI)=45-67%) of the sample were found to have fatigue severe enough to interfere with function. People that were admitted for medical reasons; had pain, spasticity, incomplete injuries, and/or were on more that one medication with a known side effect of fatigue had significantly higher FSS scores. Multivariable analysis indicated incomplete injury was the only statistically significant predictor of a higher FSS scores; pain approached significance (P=0.07, CI=-0.09, 2.06). Together these variables account for 18% of the variance in FSS scores in this sample.
CONCLUSION
Fatigue among individuals with spinal cord injury who are seeking outpatient rehabilitation is very common. The severity of fatigue was greater for individuals with incomplete lesions. Pain was also a potentially important covariate of fatigue. Further research is required to determine what else contributes to fatigue severity beyond these clinical variables as only minimal variance was accounted for in our model.
