An Eight-week RCT of Home-based Pilates for Symptoms of Anxiety, Depression, and Fatigue Among People With MS

Study Overview
=================
Brief Summary
-----------------
This study will investigate the effects of eight-weeks home-based Pilates on symptoms of anxiety, depression, and fatigue among people with Multiple Sclerosis. Half of participants will perform two weekly home-based Pilates sessions guided by a DVD, while the other half will maintain their regular daily activities.

Detailed Description
-----------------
This will be a home-based, single blind, randomised, controlled trial comparing immediate-start home-based Pilates with a delayed-start control group. The study protocol was approved by the University Research Ethics Committee. Participants will provide written informed consent prior to testing. The home-based setting promotes national recruitment of participants through the MS Society of Ireland, via distribution of posters and participation information leaflets on social media and text alerts to members. Interested participants will be invited to contact the lead researcher via phone or email, who will answer any study-related questions. Potential participants will be screened for selection criteria over the phone and provided with Participant Information Sheet (PIS), informed consent, Physical Activity Readiness Questionnaire (PAR-Q), and Patient Determined Disease Steps (PDDS) form via post or email. Following screening and initial baseline testing, eligible participants will be randomized to immediate-start home-based Pilates, or delayed-start control, by an independent researcher who will not be involved in outcome assessments, using a computer-generated randomisation tool (www.randomizer.org). The Home-based Pilates group will perform two weekly sessions for eight weeks, completed with at least 48-hours between sessions, in their own home, supported by a DVD developed and previously implemented and evaluated by the lead researcher in a feasibility trial among people with Multiple Sclerosis. The instructor on the DVD is a certified Pilates Instructor. Each participant will receive documented details of the Pilates protocol, along with the DVD which will operate on a DVD player or participant's laptop computer. On activating the DVD, participants will be provided with an opening screen, offering four options to choose from; Play all plays the entire contents of the DVD from start to finish; Warm Up, provides introductory teaching points on the core principles of Pilates along with teaching and demonstration of the Pilates' warm-up exercises; Main Phase provides demonstrations and key teaching points of the fourteen Pilates exercise routine, and Post Stretch demonstrates and teaches the post-stretch exercises. Each Pilates session will last approximately one hour and is comprised of seven Pilates warm-up exercises and fourteen mat-based beginner's level exercise. Four repetitions of each Pilates movement will be performed during sessions in the first two weeks, with intensity being self-regulated by the participant based on level of physical condition. Repetitions will gradually progress at biweekly intervals, resulting in ten repetitions being performed for the final two weeks of the trial (Weeks 7 and 8). Six post-training stretches will be maintained for a minimum of thirty seconds. Fidelity, adherence, dose and compliance shall be monitored via self-report exercise diaries containing session date, number of repetitions completed per exercise, and session RPE (Rate of perceived exertion), recorded by the participant immediately following session completion. Exercise diaries will be supplemented by a weekly telephone call consisting of direct questions about the frequency, intensity, and duration of the Pilates they have completed and whether they have experienced difficulties with exercise completion, any adverse events or relapses. The Delayed-Start Control group be instructed to maintain their pre-intervention physical activity levels during the trial and will be contacted by the lead researcher by email or telephone to ensure timely completion of the on-line outcome assessments at biweekly intervals. Following the 8-week intervention, Delayed-Start participants will be provided with the Pilates DVD for their own use, but no data will be collected. For both groups, participants who experience a relapse will be immediately withdrawn from the study, which will be recorded by the lead researcher.

| Modified Fatigue Impact Scale (MFIS) | The 21-item MFIS is a recommended core outcome measure in exercise studies in people with Multiple Sclerosis, that measures physical, cognitive and psychosocial components of fatigue. Participants respond to how often fatigue has affected you in this way during the past 4 weeks, using a 5-point Likert scale ranging from 0 (Never) to 4 (Almost Always). Physical subscale scores range from 0 to 36, Cognitive from 0 to 40, and Psychosocial from 0 to 8. Total MFIS scores (0 to 84), is computed by summing physical, cognitive, and psychosocial subscale scores, with a higher score indicating greater impact of fatigue on participant activities. A total fatigue cut-off score of ≥38 distinguishes between fatigued and non-fatigued individual. It has been proposed by the Multiple Sclerosis Council for Clinical Practice Guidelines as a reliable assessment tool of perceived fatigue (1998), with excellent test-retest reliability, and good correlation with the Fatigue Severity Scale. | Baseline |
