Stemming the Tide: The Proactive Role of Allied Health Therapy in Parkinson's Disease

Abstract

Motor and nonmotor symptoms occur in early Parkinson's disease (PD), or even in the prodromal stage. Many of these symptoms can be addressed by allied health therapies, including physical therapy, occupational therapy, speech therapy, and psychological therapies. However, referrals to these services early in the disease are low. We provide a review summarizing the efficacy of proactive allied health interventions on motor and nonmotor symptoms and daily function in prodromal and early disease. We also highlight areas for additional research and provide recommendations to improve care for individuals with early PD within each discipline. We recognize the overlapping roles of the allied health disciplines and support integrated or transdisciplinary care beginning soon after diagnosis to help stem the tide in the progression of PD symptoms and disability. Plain Language Summary Many people with Parkinson's disease start having symptoms years before their diagnosis. These symptoms can affect movement, communication, mood, work, and other aspects of daily life. Allied health therapies can be used soon after diagnosis, or even when diagnosis is suspected, to address these challenges proactively. This article reviews the roles of physical, occupational, speech, and psychological therapies. We highlight interventions for early Parkinson's disease that are strongly supported by research, such as exercise and self-management.
