This review evaluated the efficacy of dual-task training in patients with Parkinson's disease and found that it is associated with significant improvement in motor and balance abilities.
Objective Parkinson's disease is one of the most common neurodegenerative diseases in the world, which seriously damages motor and balance ability. Dual-task training is discussed as an appropriate intervention. The aim of this review was to synthesize the existing research findings on the efficacy of dual-task training for people with Parkinson's disease. Data resources A systematic search on PubMed, CENTRAL, Embase, Web of Science, and PEDro, randomized-controlled trials (RCTs) of dual-task training for individuals with Parkinson's disease. Methods Articles published until 1 November 2022 were included. Our search identified 7 RCTs with a total of 406 subjects. Review Manager 5.4 software was used for bias evaluation and to process the results of the outcome measures collected from the investigations. Results Dual-task training was associated with significant improvement in most motor and balance outcomes including gait velocity (standard mean difference (SMD) = 0.62; 95% CI, 0.37-0.87; I-2 = 31%; P = 0.21), cadence (SMD = 0.29; 95% CI, 0.05-0.53; I-2 = 0%; P = 0.71), timed-up-and-go test (mean difference (MD) = -2.38; 95% CI, -3.93 to -0.84; I-2 = 32%; P = 0.22) and mini-balance evaluation systems test (MD = 2.04; 95% CI, 1.05-3.03; I-2 = 0%; P = 0.92). Conclusion Evidence from meta-analyses suggests that dual-task training may improve motor and balance abilities in Parkinson's disease patients. Future research should focus on finding the most appropriate dual-task treatment model for patients with different degrees, in order to further improve the rehabilitation treatment of Parkinson's disease.
