Exercise for People with Parkinson's Disease: Updates and Future Considerations.

Parkinson's disease (PD) is now the world's fastest-growing neurological disorder with rapidly rising prevalence and increasing demand for effective health services. Recent research has focused on the importance of early diagnosis and proactive management of physical function. Accumulating evidence indicates that reduced physical activity levels and mild pre-clinical disability are present in many people prior to a clinical diagnosis, perhaps developing over years. Early referral to a physiotherapist at the time of diagnosis is now recommended in global guidelines. Multiple forms of exercise have been found to have benefits in early and mid-stage disease across a range of motor and non-motor symptoms. Evidence from longitudinal studies confirms that disability is delayed when regular exercise is sustained over long periods. Exercise is now recognized as an essential component of treatment, in combination with medical therapies. Contemporary physiotherapy interventions now combine health behavior change techniques with physical exercise to promote the development of long-term exercise adherence. Advances in technology and digital health have progressed quickly and now offer opportunities for remote assessment and monitoring, remote exercise supervision, and support adherence through feedback and motivational strategies. Recent biomedical discoveries forecast improved earlier and more accurate diagnosis of PD, allowing opportunities for earlier interventions. Current research in progress will provide important insights into the dose and intensity of aerobic exercise in PD. Physiotherapists have important roles in advocacy and education in conjunction with care delivery to support access to evidence-based care for all people with PD.
