 In the recent 2015 MS Society of Canada MS Wellness Survey almost 25 of people indicated that they think physical activity is the most important area of wellness, yet physical inactivity is still common in individuals with multiple sclerosis MS. While some of this may be due to factors related to MS such as fatigue, pain, and physical restrictions, research has shown that exercise has beneficial effects on mobility, strength, balance, and overall quality of life. However, because the symptoms of MS vary, there is not one optimal exercise program that exists. Pilates may be a good exercise option for MS. Pilates focuses on body positions and movement, with specific attention on the core stomach or trunk muscles. Very few researchers have studied Pilates in MS, but those that have, noticed some improvements in walking, balance, and strength. There were no negative effects reported from the Pilates exercises, and the exercises can be adapted for all levels of ability in MS. We are interested in studying the effect of Pilates in MS. To do this, we will recruit 30 people with MS to participate in this study. Participants will be randomly put into either the Pilates group or the control group. Those individuals in the Pilates group will attend two 50-minute Pilates classes twice weekly, plus receive a weekly 1-hour massage therapy session. Individuals in the control group will only receive the weekly massage therapy session. At the end of the study 12 weeks, we will look to see if there are any differences between the two groups in walking ability. We will also compare other important outcomes such as muscle strength, balance, and quality of life between the two groups. Results from this study may provide individuals with another exercise option to help manage their MS and improve their wellness. Results will also be useful for organizations such as the MS Society to help make decisions about which programs and services to offer to individuals with MS.
