Abstract
Methods A meta-analysis was conducted by systematically searching PubMed, Embase, and Cochrane Library databases till August 2020 for studies published in English. The reference lists of eligible studies were also searched. The motor symptoms (UPDRS-Part III), balance function (BBS and BESTest), functional mobility (TUG), anxiety (HADS and BAI), depression (HADS and BDI), and the quality of life (PDQ-39 and PDQ-8) were the primary evaluation indexes. Results Ten studies including 359 participants were included in this meta-analysis. The pooled results showed significant difference between the yoga training group and the control group. Patients in the yoga training group had better functional outcomes in terms of motor status (MD = −5.64; 95% CI, -8.57 to -2.7), balance function (SMD = 0.42; 95% CI, 0.08 to 0.77), functional mobility (MD = −1.71; 95% CI, -2.58 to -0.84), anxiety scale scores (SMD = −0.72; 95% CI, -1.01 to -0.43), depression scale scores (SMD = −0.92; 95% CI, -1.22 to -0.62), and QoL (SMD = −0.54; 95% CI, -0.97 to -0.11). Conclusion Our pooled results showed the benefits of yoga in improving motor function, balance, functional mobility, reducing anxiety and depression, and increasing QoL in PD patients.
Highlights
Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease worldwide, only behind Alzheimer’s disease [1]
The inclusion criteria were as follows: (1) studies designed as randomized clinical trials (RCTs); (2) participants diagnosed with PD, rather than Parkinson’s syndrome; (3) participants should be divided into at least two groups, the experimental group with yoga intervention and the control group; and (4) the study should report at least one preestablished outcome
The results indicated that yoga yielded significant improvement in terms of quality of life (QoL) of PD patients (SMD = −0:54; 95% confidence intervals (CIs), -0.97 to -0.11; P = 0:01)
Summary
PD is the second most prevalent neurodegenerative disease worldwide, only behind Alzheimer’s disease [1]. Previous studies have revealed that rehabilitation therapy, as an adjuvant strategy, could slow down the progression of PD and improve motor function, functional mobility, balance, and the health-related QoL of the patients. There was no consensus on the impact of yoga on PD This meta-analysis is aimed at investigating the effects of yoga intervention on motor function, nonmotor function, and QoL in patients with PD. Patients in the yoga training group had better functional outcomes in terms of motor status (MD = −5:64; 95% CI, -8.57 to -2.7), balance function (SMD = 0:42; 95% CI, 0.08 to 0.77), functional mobility (MD = −1:71; 95% CI, -2.58 to -0.84), anxiety scale scores (SMD = −0:72; 95% CI, -1.01 to -0.43), depression scale scores (SMD = −0:92; 95% CI, -1.22 to -0.62), and QoL (SMD = −0:54; 95% CI, -0.97 to -0.11). Our pooled results showed the benefits of yoga in improving motor function, balance, functional mobility, reducing anxiety and depression, and increasing QoL in PD patients
