Evidence-Based Physiotherapeutic Interventions Enhancing Hand Dexterity, Activities of Daily Living and Quality of Life of Parkinson's Disease Patients: A Systematic Review.

ABSTRACT

OBJECTIVES: This systematic review primarily aims to identify the optimal physiotherapeutic intervention to improve hand dexterity in Parkinson's Disease (PD) patients. The secondary objectives were to identify the hand dexterity physiotherapeutic interventions available for PD patients, and to determine the quality of these interventions. REVIEW METHODS: Eight electronic databases were systematically searched to identify relevant randomized controlled trial full-text articles using the established search strategy. The primary outcomes of interest were measurements for hand dexterity and activities of daily living (ADL). RESULTS: A total of 11 studies comprising 647 participants with PD were included. Most studies had a high risk of performance bias and an unclear risk of selection bias. The intervention training period ranged from a single session to 12 weeks. Compared to their respective control group, eight out of 11 studies revealed significant results in hand dexterity, two out of three studies reported positive effects on ADL, four of seven studies showed significant improvements in upper limb motor performance, and two studies perceived positive benefits in terms of overall quality of life. Five out of 11 studies that recorded the occurrence of adverse events reported no adverse events post-intervention. CONCLUSION: The dearth of evidence made it difficult to support any one intervention as the best intervention when compared to the other PD treatments in upper limb rehabilitation. Regardless, a home-based dexterity rehabilitation programme is still a promising approach to enhance dexterity-related functional abilities.
