Theory Based Intervention Program to Support Physical Activity for Individuals With Multiple Sclerosis: a Case Series

Study Overview
=================
Brief Summary
-----------------
This study evaluates the effectiveness of personalized physical activity coaching combined with the use of a physical activity monitor to support increased levels of daily physical activity in individuals with multiple sclerosis. All five participants will receive the intervention over the four week intervention phase.

Detailed Description
-----------------
Individuals with multiple sclerosis engage in less daily physical activity than the general population for a variety of reasons. This research project is intended to evaluate whether individualized coaching combined with the use of a Fitbit physical activity wristband monitor will improve physical activity levels in individuals with multiple sclerosis. Following admission into the study, participants will be visited once a week for four weeks at home by a physical therapist. The participants in consultation with the physical therapist will set daily physical activity goals for the following week and the participants will be taught how to monitor their daily activity using a Fitbit physical activity wristband. The goals of this study are to determine whether this intervention is effective in helping participants increase their levels of daily physical activity and their confidence that they can successfully engage in daily physical activity. In addition, there will be an evaluation of changes from pre-intervention to post-intervention in quality of life measures.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Single Arm<br>All five participants in the study will receive this intervention. The participants will be visited in their homes by a physical therapist once a week. The physical therapist will use a coaching technique called motivational interviewing to help the participant develop personal physical activity goals. The participant will discuss their physical activity challenges, and with the help of the physical therapist the participant will set up personal physical activity goals for the following week. The participant will be given a wristband physical activity monitor to wear during the day for four weeks to track their progress in meeting their activity goals. | Behavioral: Motivational Interviewing<br>* The participant will describe their unique physical activity challenges and their physical activity goals with the physical therapist. Using the technique of motivational interviewing, the physical therapist will work with the participant to help identify potential solutions to challenges and set realistic activity goals for the next week. Each week, the participant and the physical therapist will review the previous week's activity data, and the participant's reports of any challenges or problems they encountered in meeting their physical activity goals the previous week. The participant will identify new activity goals for the next week.<br>* Other names: Coaching;Device: Wristband physical activity monitor<br>* The participant will wear a Fitbit wristband which will track the participant's daily steps and minutes of physical activity.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Steps Taken Over Course of the Study | Wristband physical activity monitor recorded steps taken by participant over the 4 weeks of the study. No minimum or maximum. No baseline taken so cannot compare pre-intervention to post intervention. | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Exercise Self-Efficacy Questionnaire | The Exercise Self-Efficacy Scale is the participant's self-reported confidence in their ability to engage in exercise throughout the day. Each of the 6 items is scored from 0% confidence to 100% confidence. All items are summed and the score is divided by 6 Minimum score: 0 Maximum score:100 Higher scores mean a better outcome. | baseline and at end of 4-week intervention | 
| Multiple Sclerosis Self-Efficacy Scale | The Multiple Sclerosis Self-Efficacy Scale is a self-report of impact of multiple sclerosis on quality of life. The 14 statements are answered by selecting one of six options from strongly disagree to strongly agree. Minimum value: 14 Maximum value: 84 Higher scores reflect mean a better outcome. | baseline compared to end of 4-week study | 
| Multiple Sclerosis Impact Scale | The Multiple Sclerosis Impact Scale is a self-report on how multiple sclerosis has impacted day-to-day life during the past 2 weeks. The 29 items are graded by the participants on a 5 point scale rating from not at all to extremely. Minimum score: 29 Maximum Score:145 Higher scores mean worse outcome. | baseline compared to end of 4-week study |
