Delivering Multidisciplinary Rehabilitation Care in Parkinson's Disease: An International Consensus Statement.

BACKGROUND: Parkinson's disease (PD) is a complex neurodegenerative disorder impacting everyday function and quality of life. Rehabilitation plays a crucial role in improving symptoms, function, and quality of life and reducing disability, particularly given the lack of disease-modifying agents and limitations of medications and surgical therapies. However, rehabilitative care is under-recognized and under-utilized in PD and often only utilized in later disease stages, despite research and guidelines demonstrating its positive effects. Currently, there is a lack of consensus regarding fundamental topics related to rehabilitative services in PD. OBJECTIVE: The goal of the international Parkinson's Foundation Rehabilitation Medicine Task Force was to develop a consensus statement regarding the incorporation of rehabilitation in PD care. METHODS: The Task Force, comprised of international multidisciplinary experts in PD and rehabilitation and people directly affected by PD, met virtually to discuss topics such as rehabilitative services, existing therapy guidelines and rehabilitation literature in PD, and gaps and needs. A systematic, interactive, and iterative process was used to develop consensus-based statements on core components of PD rehabilitation and discipline-specific interventions. RESULTS: The expert-based consensus statement outlines key tenets of rehabilitative care including its multidisciplinary approach and discipline-specific guidance for occupational therapy, physical therapy, speech language pathology/therapy, and psychology/neuropsychology across all PD stages. CONCLUSIONS: Rehabilitative interventions should be an essential component in the comprehensive treatment of PD, from diagnosis to advanced disease. Greater education and awareness of the benefits of rehabilitative services for people with PD and their care partners, and further evidence-based and scientific study are encouraged.

A pilot study to investigate shoulder muscle fatigue during a sustained isometric wheelchair-propulsion effort using surface EMG.

OBJECTIVE: The primary aim of this pilot study was to develop a testing protocol for gathering shoulder muscle surface electromyography (EMG) data during a sustained submaximal isometric wheelchair-propulsion effort. Of special interest was analysis of the median frequency of the surface EMG signal power spectrum; a negative median frequency shift during a sustained effort is an indicator of muscle fatigue. The long-term goal is to improve our understanding of how fatigue and muscle imbalance might play a role in the development of a broad array of upper-extremity overuse syndromes. METHOD: Participants were a convenience sample of seven male manual-wheelchair users with spinal cord injury and 14 able-bodied males. Surface EMG in six right-side shoulder muscles was recorded while subjects resisted a static force equal to 60% of their maximum wheelchair-propulsion strength until fatigued. Percent of maximum voluntary contraction and the median frequency shift for each muscle were analyzed. RESULTS: The able-bodied group used a higher percent of maximum than the manual-wheelchair group (p< .05), and a more pronounced negative median frequency shift was evident in the able-bodied group (p < .10). CONCLUSION: Patterns that emerged suggest that spectral analysis of the surface electromyographhic signal has promise as a clinically useful tool to authenticate muscle fatigue in the upper extremities during occupational performance. Such data in the future could be used to justify the need for and benefits of adapted performance techniques and assistive technology.
