Community-based Multimodal Rehabilitation Improves Function and Performance in Postural Orthostatic Tachycardia Syndrome (POTS)

BackgroundIndividuals with neurologic impairment, such as brain injury, are more likely to have autonomic dysfunction, including POTS, but often experience a lack of treatment options and access to quality care.ObjectiveExamine the feasibility and outcomes of a group-based multimodal rehabilitation training program.MethodsNineteen females, ages 18-53 (M = 28.6) completed the outpatient training program. The intervention included eight 50-min weekly sessions using an interdisciplinary, multimodal approach, including education, movement, and mindful self-compassion. Participants completed demographic and medical history and assessment for baseline orthostatic intolerance. At pre-training, post-training, and follow-up, participants completed the Modified Fatigue Impact Scale (MFIS), Lower Extremity Functional Scale (LEFS), Rand 36-Item Health Survey 1.0 (RAND-36), Trail Making Test (A and B) (TMT-A, TMT-B), 10-Meter Walk Test (10MWT), and grip strength testing.ResultsAt baseline, participants were significantly below norms in daily function (p < 0.001), grip strength (p ≤ 0.001) gait speed (p < 0.001), fatigue (p < 0.001), and quality of life (p < 0.001). Between pre-training and follow-up, participants showed significant improvement across function in daily life tasks (p < 0.01); grip strength in the dominant (p < 0.01) and non-dominant (p < 0.01) hands; gait speed (p < 0.05); levels of fatigue (p < 0.05); cognitive performance (p < 0.05); and quality of life (p < 0.05).ConclusionIndividuals with POTS face functional challenges that can be significantly and objectively improved through multimodal rehabilitation. There is a need for provider education and further research to optimize care and quality of life for individuals with POTS.
