Self-efficacy training as an adjunct to exercise in a person with progressive multiple sclerosis: a case report.

Background: Increasing self-efficacy to exercise and minimizing disease-related barriers has been shown to improve physical activity levels and quality of life (QOL) in persons with multiple sclerosis (MS). Currently, little research has examined exercise self-efficacy in persons with more advanced MS. Purpose: Explore the effects of a self-efficacy plus exercise intervention on physical activity endurance and level, QOL, and fatigue in an individual with advanced MS and low self-efficacy.

Methods: The participant was a 60-year-old, severely disabled female with secondary progressive MS and an Expanded Disability Status Score (EDSS) of 8. The 8-week intervention consisted of weekly discussions and MS-related education; four one-on-one sessions with a MS "mentor;" daily journal to record sleep quality, fatigue level, and physical activity. Outcomes included a modified 5-meter walk test (5MWT), MS Impact Scale (MSIS-29), Exercise Self-Efficacy Scale (EX-ES), Modified Fatigue Impact Scale (MFIS), MS Self-Efficacy Scale (MS-SES), Patient Health Questionnaire-9 (PHQ-9), and daily physical activity monitoring. Outcomes were assessed at baseline (week 0), post-intervention (week 8), and 8 weeks post intervention (week 16). The participant continued her regular exercise routine independently throughout the study period.

Results: There were notable improvements in EX-ES, MFIS, PHQ-9, MSIS-29 psychological subscale, sleep quality, and morning fatigue ratings post intervention, some of which were retained at follow up.

Conclusion: The findings illustrate that an 8-week self-efficacy intervention increased exercise self-efficacy, QOL, and reduced perceived fatigue in a severely disabled individual with progressive MS. Future research should examine self-efficacy interventions in a larger sample size of persons with progressive MS.
