"[We say] movement is medicine. Find what you love, or maybe it's an opportunity to try something you've never tried before. There are some trials going on right now. [For example], the SPARX3 trial is looking at levels of intensity of aerobic activity that may be necessary to drive potentially disease modification. We're learning every day—how much, when to start—but until we have everything dialed in, get moving.”
Parkinson disease (PD) is among the fastest-growing neurodegenerative disorders worldwide, with rising prevalence, increasing disability, and significant impact on mortality.1 Alongside pharmacological treatments, there has been expanding interest in nonpharmacological interventions aimed at managing the motor and nonmotor symptoms associated with the disease. These approaches include therapies targeting speech, swallowing, and respiratory function, which can contribute to daily functioning and quality of life. Ongoing research continues to evaluate the effectiveness and broader applicability of these interventions across diverse patient populations.
Among these interventions, Lee Silverman Voice Treatment (LSVT LOUD) has emerged as a validated and widely used therapy. Following a standardized protocol of intensive, high-effort speech exercises, LSVT LOUD is designed to improve communication and vocal loudness in individuals with PD.
Research has shown that, in addition to enhancing voice, standard LSVT LOUD therapy may also produce positive “spread effects,” improving swallowing and cough function.2 Complementing voice therapy, LSVT BIG is an exercise program developed specifically for patients with PD. A recently published review suggested that LSVT BIG may be more effective than general exercise in improving gait speed and overall motor function in patients with mild to moderate PD.3
At the 4th Annual Advanced Therapeutics in Movement and Related Disorders (ATMRD) Congress, held by the PMD Alliance from June 27-30, 2025, speech language pathologist Cynthia Fox, PhD, CCC-SLP, CEO and co-founder of LSVT Global, highlighted the benefits of evidenced-based speech and physical therapies including LSVT LOUD and LSVT BIG for PD.4 In an interview with NeurologyLive® at the meeting, Fox emphasized that these structured, high-intensity programs aim to help patients regain functional abilities, improve posture, gait, and vocal volume. She shared meaningful outcomes observed in an older patient case, underscoring the value of combining exercise, occupational therapy, and behavioral interventions to enhance the patient’s quality of life.

Clinical Perspective — Dr. Vikram Patel, Neurology
Workflow: As I incorporate speech and movement therapy into my practice, I'm finding that I now routinely recommend therapies like LSVT LOUD and LSVT BIG to my patients with Parkinson's disease. With research showing that these therapies can improve communication, vocal loudness, and motor function, I'm adjusting my treatment plans to include these evidenced-based approaches. For example, I'm considering referring patients to programs like the SPARX3 trial to explore the benefits of aerobic activity.
Economics: The article doesn't address cost directly, but I'm considering the potential long-term savings of nonpharmacological interventions like LSVT LOUD and LSVT BIG. By improving motor and nonmotor symptoms, these therapies may help reduce the need for other treatments or interventions down the line, potentially leading to cost savings.
Patient Outcomes: I'm seeing tangible benefits for my patients with Parkinson's disease who undergo therapies like LSVT LOUD and LSVT BIG. Research has shown that LSVT LOUD can improve swallowing and cough function, and LSVT BIG may be more effective than general exercise in improving gait speed and overall motor function in patients with mild to moderate PD, which can significantly impact their quality of life.
