Efficacy of an energy conservation course for persons with multiple sclerosis

Arch Phys Med Rehabil. 2001 Apr;82(4):449-56. doi: 10.1053/apmr.2001.22192.


Objective: To evaluate the efficacy of an energy conservation course on fatigue impact, self-efficacy, and quality of life (QOL) for persons with multiple sclerosis (MS).

Design: Repeated measures with control and experimental interventions conducted during a 19-week study.

Setting: Community-based treatment center.

Participants: A convenience sample of 54 individuals from 79 community-dwelling volunteers with fatigue secondary to MS.

Intervention: A 6-session, 2-hr/wk energy conservation course taught by occupational therapists for groups of 8 to 10 participants.

Main outcome measures: Fatigue Impact Scale (self-report measure of fatigue impact on cognitive, physical, social functions), Self-Efficacy Gauge (self-report measure of confidence in ability to perform specific behaviors), and Medical Outcomes Study Short-Form Health Survey (QOL measure).

Results: Participants reported, as predicted, significantly less fatigue impact, increased self-efficacy, and improved QOL (ie, 3 of 4 subscales expected to improve). There were no significant differences, as predicted, in any of the dependent variables after the control (ie, support group) and no intervention periods.

Conclusion: Results provide strong evidence for the efficacy of this energy conservation course for persons with MS.
