- Brief Summary
This project involves two sub-parts:
Study 1: Effect of lab-based Functional Balance Intervention (FBI) for physical and cognitive symptoms of Multiple Sclerosis.
Study 2: Feasibility of home-based FBI for physical and cognitive symptoms of Multiple Sclerosis.
Each study involves a 2-arm, Phase-1, randomized controlled clinical trial to evaluate the effect of FBI on physical, cognitive function, and daily living among people with MS (PwMS). Study 1 is conducted in a lab setting, while Study 2 is conducted at home with additional safety measures. A total of 150 people with multiple sclerosis will be recruited and telephone screened, with an expected enrollment of 120 (60 per phase). After in-person screening, 96 eligible participants (48 per phase) will undergo pre-training assessment and randomization into FBI or Stretching groups. Training sessions will occur twice a week for four months. Anticipating a 15-17% attrition rate, the target sample size is 80 (40 per phase) for completion of the study. Post-training assessments will be conducted after four months to evaluate FBI's impact on physical and cognitive functions. This evidence-based protocol, previously successful with neurological and older adult populations, intends to provide a low-cost, safe, and effective intervention for PwMS in clinical and community settings, including rural areas.
- Detailed Description
1.0 BACKGROUND/SCIENTIFIC RATIONALE (Study 1 and 2) Of the 1 million adults living with multiple sclerosis (MS) in the United States, over 80% have physical impairment, an estimated 45-60% have cognitive impairment and 20-30% will develop severe dementia. Physical deficits include muscular weakness, spasticity, sensorimotor dysfunction, and imbalance, which co-occur with cognitive dysfunction and directly impact community mobility and overall quality of life. Cognitive deficits include slowed processing speed and reaction time, poor executive functions like planning and problem-solving, and learning and memory deficits. Physical and cognitive deficits rarely remit after onset and are associated with secondary problems with mobility and balance, resulting in increased fall-risk. Whereas treatments targeting restoration of physical function in PwMS have been established, research informing effective management of cognitive dysfunction is in its early stages. Further, there is limited evidence for pharmacological and rehabilitation approaches that can target both physical and cognitive dysfunction. Yet, there have been recent calls for greater focus on unique modes of exercise training as the most promising approach.
Exercise training interventions have yielded modest, but consistent improvements in physical function, walking ability, and fatigue in PwMS. Whereas there is extensive evidence on exercise training targeting physical function, there is comparatively much less known about exercise training targeting cognitive function in PwMS, and this literature is not yet conclusive. Additionally, previous interventions among PwMS have rarely incorporated components of functional balance for treating physical and cognitive dysfunction. Interventions like aerobic and/or strength training are effective in improving physical function, yet effects on cognitive dysfunction might not be very robust. Indeed, cognitive improvements after protocols of aerobic and/or strength-based exercise training might be limited because these modalities might share limited brain resources with physical domains and cognitive tasks, resulting in only a minor transfer of improvements to physical and cognitive performance. On the other hand, there is more evidence of common neural resources shared between cognitive tasks and balance control (e.g., vestibular, visuospatial processing, executive function, attention). Thus, focusing on functional balance training could have a greater activation of the central nervous system (CNS) integrative frameworks for treating cognitive dysfunction in PwMS. It could further have secondary benefits of improving fall efficacy, physical activity, and community mobility thereby mediating change in measures of quality of life among PwMS. Thus, the investigators propose a novel, multicomponent exercise intervention named Functional Balance Intervention (FBI) for improving physical and cognitive function and other measures of daily living among PwMS. The effects of FBI will be tested in a laboratory setting (Study 1) and then tested in a home-based setting (Study 2) in parallel. For both studies, the FBI will be compared to a control group, who will complete an equivalent dosage of stretching. Results from the proposed Phase-I Randomized Controlled Trial (RCT) will inform the research community to launch a line of larger Phase-II RCT examining the comparative effectiveness of the FBI program among PwMS. The findings from this project can also serve as preliminary groundwork for conducting large-scale clinical trials to assess comparative effectiveness of FBI with other pre-established interventions particularly for individuals with restricted mobility and/or restricted access to onsite healthcare services.
2.0 OBJECTIVES (Study 1 and 2) The two-study project is an alternative, non-pharmacological intervention, which represents an important avenue for treating physical and cognitive symptoms of MS and aims to impact measures of mobility and quality of life. Through this project, the investigators will simultaneously examine the effects of FBI compared to stretching among PwMS in a lab-based setting (Study 1) and home-based setting (Study 2). Study 1 and 2 will run in parallel i.e., all data collection, analysis, and dissemination activities will occur simultaneously. For both studies, the investigators first postulate that a Functional Balance Intervention (FBI) can result in immediate improvements in physical function, possibly mediated via improvements in secondary endpoints of dual-task balance, functional mobility, and gait. Secondly, the investigators postulate the possibility that cognition shares more similar neural processes with balance control than with other functional domains, such that CNS adaptations induced by functional balance training could translate into immediate in cognition40. The improvements in physical and cognitive function will mediate improvements in other measures of daily living.
Below are the combined specific aims for Study 1 and 2:
Aim 1: Examine the effect of the FBI (Intervention Group) on physical function in PwMS compared to a stretching program (Control Group).
Hypothesis 1: After 4 months of training, the FBI will show significantly higher improvements in physical function compared to the stretching.
Aim 2: Examine the effect of a multicomponent FBI on cognitive function compared to PwMS in the stretching program.
Hypothesis 2: After 4 months of training, the FBI will show significantly higher improvements in cognitive function compared to the stretching.
Aim 3: Examine the effects of the multicomponent FBI compared to the control group among PwMS on measures of daily living (dual task performance, balance confidence community mobility, and quality of life).
Hypothesis 3: After 4 months of training, the FBI will show significantly higher improvements in measures of daily living compared to stretching.
3.0 Research Design Both sub-studies included in this project (i.e., Study 1 and 2) involve a randomized controlled trial design to establish the feasibility and initial effect of a multicomponent, Functional Balance Intervention (FBI) for immediate improvements in physical and cognitive function, and measures of daily living among persons with multiple sclerosis (PwMS). Study 1 will include training sessions in the lab, and Study 2 will include training sessions at home. Data collection procedures for Study 1 and 2 will run in parallel.
A total sample of 120 participants with Multiple Sclerosis (60 in each study) will be enrolled in this project. The investigators expect \~20% in-person screening failures. Hence, the investigators expect that \~96 PwMS will be eligible to be included in the study, undergo pre-training assessment, and then randomized into 2 groups. The Interventional Group (n=24 for Study 1 and n=24 for Study 2) will undergo a multi component Functional Balance Intervention for 4 months, whereas in the Control Group (n=24 for Study 1 and n=24 for Study 2) will receive a stretching intervention for 4 months.

- Primary Outcome Measures
Name Time Method Change in self-reported community mobility Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) The University of Alabama at Birmingham (UAB) has established a paper pencil questionnaire named "Lifespace Scale Questionnaire" will be used to assess change in self-reported community mobility. The Lifespace scale questionnaire measures a person's mobility in five areas: outside the bedroom, outside the house, in the neighborhood, outside of the neighborhood but in town, and outside town during the past four weeks. Higher scores indicate greater community mobility.
Change in physical function Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Physical function will be assessed via the Short Physical Performance Battery (SPPB). This batter includes tests for standing balance and muscle strength and is widely used among older adults and people with multiple sclerosis. Higher scores indicate better performance.
Change in dual task balance performance Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Dual task balance performance will be assessed via the limits of Stability with the letter number sequencing test. The Limits of Stability test assesses balance on a computerized balance system, which requires participants to shift weight without losing balance. Maximum excursion will be the outcome assessed using the Limits of Stability test. The Letter Number Sequencing test will be performed simultaneously. This test includes cognitive task involving generating alternating number-letter sequences. The accuracy and total responses will be the outcome measures recorded via this test. Higher values for accuracy and responses indicate better performance.
Change in measured community mobility Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) The investigators will use the ActiGraph sensor to assess change in measured community mobility. Participants will be asked to wear the accelerometer device for the following 7 days for at least 12 hours per day. Participants will be asked to always wear the watch except during bathing, charging it, and sleeping. All of these are reliable and sensitive measures for assessing community mobility among people with multiple sclerosis. Greater number of steps per day indicate greater community mobility.
Change in self-reported quality of Life Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) This will be assessed using the MS Impact Scale (MSIS-29), a self-reported measure that includes both physical (20 items) and psychological (9 items) aspects of life quality. Higher scores indicate better quality of life.
Change in cognitive function Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Cognitive function will be assessed by the Brief International Cognitive Assessment (BICAMS) The BICAMS is widely used in people with MS and consists of 3 sub-tests including the Symbols Digit Modalities test for assessing processing speed, the California Verbal Learning Test-II for assessing verbal learning and memory and the Brief Visuospatial Memory also for assessing learning and memory as a part of the BICAMS. All these tests are paper pencil questionnaires to assess different domains of cognitive function. Higher scores indicate better performance.
Change in dual task gait performance Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Dual task gait performance will be assessed via the Timed-up and Go test with the letter number sequencing test. The Timed-up and Go test evaluates functional mobility among individuals with multiple sclerosis. Participants will be asked to stand from a chair, walk 3 meters, and sit back. Lesser time to complete indicates better performance. The Letter Number Sequencing test will be performed simultaneously. This test includes cognitive task involves generating alternating number-letter sequences. The accuracy and total responses will be the outcome measures recorded via this test. Higher values for accuracy and responses indicate better performance
- Secondary Outcome Measures
Name Time Method Change in balance confidence Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Balance confidence will be assessed using the Activities-Specific Balance Confidence Scale (ABC), which asks individuals to rate their level of confidence (0-100%) that they will not lose their balance while performing various activities of daily living, such as getting onto an escalator or reaching into a cabinet. This measure has also been shown to be reliable for assessing people with multiple sclerosis. Higher percentage scores indicate better confidence.
Change in walking speed Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Walking endurance will be assessed using the Timed 25-Foot Walk test. This test measures mobility and leg function performance and is a reliable assessment of used commonly among people with multiple sclerosis over time. Lesser time to complete the test indicates better performance.
Change in walking performance Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Walking performance will be assessed via the the Dynamic Gait Index (DGI). This test examines dynamic balance through various functional tasks performed in daily living and is a commonly used test among individuals with multiple sclerosis. Higher scores indicate better performance.
Change in functional independence Week 3 (Pre-training Assessment), Week 21 (Post-training assessment) Functional independence will be assessed via the Functional assessment measure (FAM). This test is a 12-item assessment measure to assess functional independence among people with Multiple Sclerosis. The items include self-care items, sphincter control, mobility items, locomotion, communication and psychological adjustment and cognitive function. Higher scores indicate more independence.
