Examining the Neural Effects of a Behavioral Intervention for Physical Activity in Multiple Sclerosis

Not Applicable

Completed

• Conditions: Multiple Sclerosis
• Interventions: Behavioral: Behavioral Intervention for Physical Activity in MS (BIPAMS); Behavioral: Wellness for MS (WellMS)

• Registration Number: NCT04496804
• Lead Sponsor: University of Alabama at Birmingham

Brief Summary

Multiple sclerosis \[MS\] is a prevalent neurological disease that is the leading cause of irreversible neurological disability among young women and the second leading cause of disability among young men in the United States. This disease results in the progressive loss of walking mobility and substantial worsening of cognition, symptoms, and quality of life over time. There is evidence that physical activity is beneficially associated with aerobic fitness and brain structure and function in persons with MS. Nevertheless, this population is strikingly sedentary and physically inactive. This highlights a vital opportunity to improve aerobic fitness and brain health by developing behavioral interventions that increase physical activity. To that end, this project is a Phase-II randomized control trial for examining the efficacy of a behavioral intervention that is based on social-cognitive theory and delivered through the Internet for increasing physical activity and, secondarily, improving aerobic fitness and brain structure and function in persons with MS.

Arm && Interventions

Group	Intervention	Description
Behavioral Intervention for Physical Activity in MS (BIPAMS)	Behavioral Intervention for Physical Activity in MS (BIPAMS)	The current behavioral intervention consists of two primary components; an Internet website and one-on-one video chats with a behavioral coach. The Internet website involves content delivered through interactive video courses. The interactive video courses are based on elements of social cognitive theory. Each courses consists of an introduction, the primary content, and a take home message. The interactive courses include embedded, supplementary options such as videos on content and worksheets related to the topic. A pedometer is provided for tracking steps, and these steps will be entered into the website so progress can be monitored. The chats support adherence to the intervention, discussion of website material, supportive accountability, and reporting of adverse events/injuries. The chats are conducted face-to-face through Skype. The chats occur 7 times during the first 2 months, 4 times during the second 2 months, and twice during the final 2 months of the intervention.
Wellness for MS (WellMS)	Wellness for MS (WellMS)	Provides an Internet website and one-on-one video chats that discuss materials about self-managing multiple sclerosis (MS) consequences and health indicators through methods other than physical activity. The materials are transformations of brochures provided by the National MS Society, including Gait or Walking Problems: The Basic Facts; MS and Your Emotions; Pain: The Basic Facts; Solving Cognitive Problems; Taming Stress in MS; Food for Thought: MS and Nutrition; and Vitamins, Minerals, and Herbs: An Introduction. The delivery of the Internet materials and chat sessions will occur on the same time schedule and frequency as the intervention condition, and will have a comparable time commitment. The control condition will not involve tracking steps and a pedometer with not be provided.

Primary Outcome Measures

Name	Time	Method
Minutes of moderate to vigorous physical activity - Baseline	Assessment will be conducted before the intervention	Activity monitors are Actigraph accelerometers that participants will wear on an elastic belt around their waist for 7 days. These activity monitors measure how frequently and how much an individual moves.
Minutes of moderate to vigorous physical activity - Post intervention	Assessment will be conducted immediately after the intervention	Activity monitors are Actigraph accelerometers that participants will wear on an elastic belt around their waist for 7 days. These activity monitors measure how frequently and how much an individual moves.

Secondary Outcome Measures

Name	Time	Method
resting state functional brain connectivity - post intervention	Assessment will be conducted immediately after the intervention	An MRI will be conducted to measure brain function.
cardiorespiratory fitness; oxygen consumption during exercise - baseline	Assessment will be conducted before the intervention	A graded exercise test on a treadmill. Participants will walk at a quick pace on the treadmill and the incline will increase every 2 minutes until the participant is no longer able to keep pace with the treadmill.
distance walked - baseline	Assessment will be conducted before the intervention	The six-minute walk test will be used to measure walking endurance. The test involves walking for 6 minutes without stopping.
distance walked - post-intervention	Assessment will be conducted immediately after the intervention	The six-minute walk test will be used to measure walking endurance. The test involves walking for 6 minutes without stopping.
information processing speed; cognitive function - baseline	Assessment will be conducted before the intervention	The symbol digit modalities test will be used to measure information processing speed. The test involves matching numbers to symbols.
volume of subcortical grey matter brain structures - baseline	Assessment will be conducted before the intervention	An MRI will be conducted to measure brain structure.
cardiorespiratory fitness; oxygen consumption during exercise - post intervention	Assessment will be conducted immediately after the intervention	A graded exercise test on a treadmill. Participants will walk at a quick pace on the treadmill and the incline will increase every 2 minutes until the participant is no longer able to keep pace with the treadmill.
