A pilot study has been launched to assess the immediate and enduring benefits of tai chi and mindfulness meditation on the physical balance and mental wellness of people with multiple sclerosis (MS). This community-based study — currently enrolling participants — is being conducted by the Motor Control Lab directed by Richard van Emmerik, PhD, professor of kinesiology at the University of Massachusetts Amherst. The project was awarded a $54,972 one-year grant from the National Multiple Sclerosis Society. While many MS symptoms vary from patient to patient, depending on the extent and location of the damage in the brain and spinal cord, difficulty in maintaining physical balance is a generalized complaint. Several MS symptoms can have an effect on balance, including difficulties with coordination, tremor and muscle weakness, stiffness, or dizziness and vertigo. "Mind-body interventions are beneficial as they train dynamic balance, such as transitioning between postures, turning, reaching, etc., in a manner similar to movements in daily life," Julianna Averill, a doctoral student at van Emmerik’s lab, said in a press release. Postural control and balance confidence is crucial to prevent patients' falls and reduce their fear of falling. Finding strategies that help patients cope and overcome this limitation is crucial, Averill noted. Contrary to other studies, which focus on mental health benefits, this project will look mostly at the effects of mindfulness practice on physical balance. Tai chi also will be evaluated for its potential to improve patients’ balance, both while they are standing and as they move. Participants will be randomly assigned to either eight weeks of free tai chi at YMAA Western Mass Tai Chi or mindfulness meditation classes at Downtown Mindfulness, in Hampshire County, Massachusetts. Tai chi is a Chinese martial art that involves body stretching and slow, focused, flowing postures that keep the body in motion. Mindfulness meditation is based on mindfulness practices, including training on body scan meditation, and loving kindness meditation. Participants will attend classes for 2.5 hours per week, where they will receive training to complete an additional 2.5 hours at home each week. At home, participants are asked to listen to meditation podcasts, or watch tai chi videos via a website that also tracks their activity. “The participants will be trained, and they will be able to practice on their own,” Averill said. Patients' postural sway will be recorded by wearable sensors while performing distinct movements at the study start, at the end of all classes, and two weeks later. On the same visits, participants will be surveyed to assess the frequency of falls, balance confidence, level of fatigue, and ability to cope and adapt. “We’re taking a more holistic look, considering the whole person and overall quality of life,” Averill said. The team plans to enroll 30 participants with mild-to-moderate MS symptoms, aged 21 to 70, and who are able to stand and move without assistance for 15 minutes. For more information about the study and how to participate, contact Averill at [email protected].

Oligodendrocyte precursor cells (OPCs), the cells responsible for myelin production, are unable to migrate into sites of myelin loss in the brain. These cells then cluster and disrupt the blood-brain barrier (BBB), triggering an inflammatory process in the early stages of multiple sclerosis (MS), a study shows. The study, “Aberrant oligodendroglial–vascular interactions disrupt the blood–brain barrier, triggering CNS inflammation,” was published in the journal Nature Neuroscience. MS is an autoimmune disease characterized by the loss of myelin (demyelination) — the fat-rich substance that protects nerve fibers — which leads to neurodegeneration. Along with loss of myelin, researchers have observed that the blood-brain barrier — a highly selective membrane that shields the central nervous system with its cerebrospinal fluid from the general blood circulation — breaks down in the initial stages of disease. A team led by researchers at the University of California, San Francisco, have now discovered that OPCs are involved in the disruption of the blood-brain barrier in MS, according to a press release from the National MS Society, which funded the study. Oligodendrocytes are myelin-producing cells and are responsible for myelinating the nerve cells’ axons — a single oligodendrocyte is capable of myelinating multiple axons. Mature myelin-producing oligodendrocytes develop from more immature, stem cell-like OPCs. In a normal brain, upon myelin loss, OPCs are called into action and travel into the damage site where they mature and generate myelin-producing oligodendrocytes. In this study, the researchers found that OPCs in MS form clusters in blood vessels of the brain-blood barrier, having lost the ability to detach from these vessels and migrate to injury sites. In an animal model of MS, they saw that OPC aggregates altered the location of other cells — called astrocytes — in a competition for space, and contributed to the disruption of blood vessels. Astrocytes are a group of star-shaped cells, belonging to the group of glial cells, that provide neurons with energy, and work as a platform to clean up their waste. They also have other functions within the brain, such as regulating blood flow and inflammation. The team also observed that OPC aggregates trigger an immune inflammatory response, shown by a large number of microglia (the central nervous system immune cells) and immune cells called macrophages around these cell clusters. “We find in several MS cases, in lesion areas with active inflammation, that OPCs can be found clustered on vasculature, representing a defect in single cell perivascular migration and inability to detach from blood vessels,” the researchers wrote. Further molecular analysis revealed that OPCs have high levels of Wnt signaling, and elevated secretion of Wif1 factor to the extracellular space that could explain why OPCs accumulate and destroy the blood-brain barrier. The WiF1 factor is actually a negative regulator of Wnt signaling that is essential for the maintenance of the blood-brain barrier structure. This factor competes with Wnt ligands, and affects the integrity of cellular junctions, making the blood-brain barrier more fragile and permeable. "Evidence for this defective oligodendroglial–vascular interaction in MS suggests that aberrant OPC perivascular migration not only impairs their lesion recruitment but can also act as a disease perpetuator via disruption of the BBB,” the researchers wrote. They suggested that more studies are needed to better understand the interactions between blood vessels and oligodendrocytes, which could help identify new therapeutic targets for promoting myelin repair in MS.
