comparison of two community based exercise protocols in people with multiple sclerosis

Conditions: Multiple Sclerosis

Summary: this study will compare the benefits of two community based exercise programs, personal training and whole body vibration on balance and gait in people with multiple sclerosis. anyone with a diagnosis of ms can participate in the personal training. only people who can walk with or without an assistive device with a diagnosis of ms can participate in the whole body vibration. pre testing and post testing will be completed using balance and gait measures and self reporting measures for balance confidence and impact of ms. the program will run two times per week for six weeks.

multiple sclerosis (ms) is a demyelinating disease of the central nervous system (cns) that affects approximately 400,000 persons in the united states, and 1,200,000 persons between 16 and 65 years of age worldwide. it is a neurodegenerative pathology which can be characterized by a course of demyelination-mediated relapses and remissions, superimposed upon gradual neurologic deterioration, resulting in a clinical course that is unpredictable in its progression and severity. the pathophysiology associated with ms is the slowing or stopping of saltatory conduction of action potentials along myelinated axons in the cns. this results in a clinical presentation that is varied and unpredictable in age of onset, disease progression, and the signs and symptoms experienced by each person with ms (pwms). individuals with multiple sclerosis have a variety of symptoms before and after diagnosis. common symptoms include double vision, partial loss of vision, numbness or weakness of the limbs, fatigue, depression, cognitive dysfunction, dizziness, tremor, decreased coordination, and unsteady gait. many symptoms of ms are associated with increased fall risk similar to that found in older individuals. the purpose of this study is to use and compare two different interventions in people with ms in a community setting. the first intervention is an assisted personal training program offered in a community setting to improve functional limitations and reduce risk for falls in people with ms. this exercise program will be provided by personal trainers educated in exercise training in people with ms. the personal training program is an ongoing program supported by the national ms society. the second intervention is the use of whole body vibration (wbv) platforms to improve gait ability and improve balance in people with ms. assisted personal training, circuit training has limited research in people with ms. this method of exercise is similar to exercise healthy individuals would complete in a fitness center setting with guidance from a personal trainer. in this study, the personal training program will be provided by educated personal trainers. these personal trainers completed a 24 hour continuing education course on exercise in people with neurodegenerative diseases. the facility, mindset charities has a strong ongoing personal training program for people with ms, and this program is supported by the national multiple sclerosis society (nmss). the individuals with ms attend 2 personal training sessions each week. the effectiveness of this type of program has not been studied to date. there is a desire to improve training options to increase endurance, gait ability, and balance in people with ms. in the past decade whole body vibration has been studied in athletes, older individuals, people with chronic stroke, people with parkinson disease, and there are a few studies in people with ms. during wbv training, individuals stand on the platform and complete a series of exercises designed to improve gait ability and balance. the vertical vibrations during the session are thought to cause muscle contractions initiated by sensory receptors and reduce the recruitment threshold of motor units possibly resulting in increased activation of high threshold fast twitch muscle fibers. hypothesis:1. individuals with ms who participate in either a personal training class or a wbv exercise protocol will have improvements in gait, balance, endurance, fatigue, and quality of life (qol). 2. individuals in the wbv training group will have a greater improvement in strength.
