Clinical Trial Summary

Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) affecting roughly 900,000 people in the United States that frequently results in impaired mobility. The majority of people with MS express that impaired mobility the most difficult aspect of living with the disease. Ataxia is one aspect of impaired mobility experienced by approximately 80% of persons with MS. Despite $9 billion in drug costs to patients with MS in the U.S., in 2012 alone, standard pharmacological treatment for MS is ineffective in restoring mobility and decreasing ataxia. The PI designed a targeted ballet program requiring motor learning of complex movements that mitigated ataxia and improved balance in patients with MS in a pilot study. The improvements obtained were approximately five times larger than those reported by other physical rehabilitation interventions. However, understanding these changes requires determining whether there are underlying changes in the brain after participation in the targeted ballet program.

This project involves persons with mild-to-moderate MS that present ataxia in their movement. We will compare the brain connectivity of participants in the targeted ballet program before and after the 16-week, twice per week, hourly participation intervention. Brain images will be obtained with magnetic resonance imaging while each participant rests with the eyes open. As a secondary outcome, measures of movement quality, ataxia, and balance will be taken to better understand the effects of the targeted ballet program on motor function, wellness, and the brains of persons with mild to moderate MS. Test on movement will include a 10 meter walk with motion tracking, a balance test using a force plate, and clinical tests of ataxia, balance, and walking speed. We will also assess changes in wellness with standard questionnaires.

Description:

Multiple sclerosis (MS) is an autoimmune-mediated disease with brain demyelination and axonal loss that result in impaired mobility, which affects an estimated 75% of people with MS and is reported as the most difficult aspect of living with MS. An estimated 900,000 people in the U.S. suffer from MS, which has no known cure. In 2012 alone, drug costs to patients with MS in the U.S. were $9 billion. Despite the high costs, pharmacological interventions do not induce myelination so motor impairments persist. The PI designed a ballet-based program for complex motor learning delivered in a group setting. Our previous work provides evidence that the targeted ballet program increased balance and walking scores by 42% and decreased clinical ataxia scores by 58% over a period of 16 weeks and 32 hours of instruction. However, understanding these changes requires determining whether there are underlying changes in the brain after participation in the targeted ballet program.

The goal of this proposal is to provide evidence of improvements in brain connectivity measures after participation in the targeted ballet program in persons with MS. As secondary outcomes, we will assess motor function and wellness after participation in the targeted ballet program in persons with MS.

Intervention

Behavioral:
• Targeted Ballet Program
All classes will be offered in a set schedule convenient for all participants. Classes will be taught by the PI, who has extensive dance training expertise. The targeted ballet program consists of an initial period of dance movements while sitting in chairs (20min), followed by exercises holding onto the ballet barres mounted to the walls in the Neuroscience of Dance on Health and Disability Laboratory (20min), followed by locomotive dance movements (20min). The dance moves are based on the Ballet I Syllabus of the Royal Academy of Dancing and the Cecchetti Council of America, designed for eight-year-old students with no necessary previous training in ballet.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Structural Connectivity	Mean strength, global efficiency, and mean clustering coefficient for the networks seeded from the regions of interest: the fornix, supplemental motor area, corpus callosum, orbitofrontal cortex, putamen, and cerebellum. Using Probtrackx2 in network mode, the output is a connectivity martix, which contains the number of streamlines from each seed volume (e.g., all voxels in insula cortex) that reached all other target regions. Structural connections will be normalized by the average volume of each region of interest (ROI) comprising the particular pathway to eliminate bias induced from larger ROI's. Additionally, the structural connectomes will be symmetrized by averaging the two connections in the connectivity matrix corresponding to the pair of ROI's (where one connection is ROI 1 as seed and ROI 2 as target, and the other connection flips the seed and target labels).	Before and after the 16-week intervention period
Primary	Resting-State Functional Connectivity	We will acquire one 8 minute scan for resting state functional connectivity analysis, during which participants will be instructed to maintain their eyes open and focus on a fixation point as was done in Bollaert et al. 2018. We will use a modified version of the Duke Brain Imaging and Analysis Center's (BIAC) resting-state functional connectivity to find the correlation coefficients of the resting-state blood oxygen level-dependent activation of the 68 regions from Freesurfer's parcellation and the 34 regions of the cerebellum from the spatially unbiased atlas template of the cerebellum and brainstem (SUIT) parcellation. We will use the brain connectivity toolbox (BCT) to form graph-theoretical measures of the network for evaluating changes in connectivity.	Before and after the 16-week intervention period
Secondary	International Cooperative Ataxia Rating Scale (ICARS)	The ICARS is the leading comprehensive clinical measure of ataxia for persons with MS, which has strong inter-evaluator reliability and validity.	Before and after the 16-week intervention period
Secondary	Mini Balance Evaluation Systems Test (Mini-BESTest)	This test consists of a shorter list of evaluations on six factors that may impair balance in patients with MS: biomechanics, stability limits, postural responses, anticipatory postural adjustments, sensory orientation, and dynamic balance during gait.	Before and after the 16-week intervention period
Secondary	10-Meter Walk Test (10MWT)	A clinical test of walking ability by time to complete a 10-meter long walk.	Before and after the 16-week intervention period
Secondary	World Health Organization Disability Assessment Schedule (WHODAS)	Questionnaire-based assessment of wellness and quality of life as related to disability. 36 items are used to assess disability-related wellness. Difficulty in the past 30 days for each item is scored between 1 (none) and 5 (extreme or cannot do). Six domains are assessed: Understanding and communicating (6 to 30), Getting around (5 to 25), Self-care (4 to 20), Getting along with people (5 to 25), Life activities (8 to 40), and Participation in society (8 to 40) The minimum sum score of 36 indicates no disability-related wellness problems and the maximum score of 180 indicates extreme disability-related wellness problems.	Before and after the 16-week intervention period
Secondary	World Health Organization Five Well-Being Index (WHO-5).	Questionnaire-based assessment of wellness and quality of life over the last two weeks. A minimum sum score of 0 (0 on each of five questions) indicates minimal well-being. A maximum score of 25 (5 on each of five questions) indicates maximum well-being.	Before and after the 16-week intervention period
Secondary	Smoothness Index	Quantitative measure of smoothness of movement will be obtained for walking by computing a standard smoothness index on velocity data of body landmarks such as wrists, elbows, shoulders, hips, knees, toes, ankles, and top of head in a 5 meter walk using a motion capture system (Qualisys, Sweden).	Before and after the 16-week intervention period
Secondary	Step-to-Stand Stabilization Task	Participant will step onto and stand still on a force plate to quantitatively measure static and dynamic balance.	Before and after the 16-week intervention period
