    ABSTRACT: In this randomized controlled trial, 169 persons with multiple sclerosis were randomly assigned to an immediate intervention group or a delayed control group using a crossover design. The outcome measures (Fatigue Impact Scale and SF-36 Health Survey) were measured four times before and after courses. This study investigated whether the immediate benefits of a 6-week, community-based, energy conservation course for persons with multiple sclerosis were maintained at 1-year follow-up. We performed intent-to-treat and compliers-only analyses using mixed effects analysis of variance models. Results showed that the beneficial effects were maintained 1-year postcourse compared with immediate postcourse. In addition, there were significant improvements in all three subscales of the Fatigue Impact Scale and in four subscales of SF-36 Health Survey 1-year postcourse compared with precourse. Together, these results provide strong evidence that the beneficial effects of the energy conservation course taught by occupational therapists were maintained up to 1-year postcourse.

    ABSTRACT: To assess the short-term efficacy and effectiveness of a six-week energy conservation course on fatigue impact, quality of life and self-efficacy for persons with multiple sclerosis (MS). In this randomized controlled trial, we randomly assigned 169 persons with MS to an immediate intervention group or a delayed control group using a crossover design. The outcome measures: Fatigue Impact Scale, SF-36 Health Survey and Self-Efficacy for Performing Energy Conservation Strategies were measured before and after courses and no intervention control periods. We performed intent-to-treat analysis and compliers-only analyses using mixed effects analysis of variance models. Taking the energy conservation course had significant effects on reducing the physical and social subscales of Fatigue Impact Scale and on increasing the Vitality subscale of the SF-36 scores compared with not taking the course. Additional subscales were significant depending on methods of analyses. Self-Efficacy for Performing Energy Conservation Strategies Assessment increased significantly (P <0.05) postcourse compared to precourse. Results support the efficacy and effectiveness of the energy conservation course to decrease fatigue impact, and to increase self-efficacy and some aspects of quality of life.
