Effect of group exercise on quality of life for Parkinson disease: systematic review and meta-analysis

PurposeMotor and non-motor symptoms can negatively affect quality of life (QoL) for people with Parkinson Disease (PD). Our purpose was to investigate the effects of group exercise (GE) compared to individual exercise (IE) and usual care (UC) on QoL for people with PD. A systematic review and meta-analysis were performed with randomized controlled trials that studied the effects of GE compared to IE and UC on QoL for people with PD.Materials and methodsThe systematic search was performed in EBSCO, PubMed, and Science Direct databases. Quality of methodology was assessed using the Cochrane GRADE approach. Thirteen studies met all inclusion criteria and were included in the analysis.ResultsNo significant difference was found on QoL between GE and IE; however, QoL was significantly improved with GE compared to UC. Results were based on low to moderate quality of evidence.ConclusionsBased on low to moderate quality of evidence, GE has a similar effect on QoL when compared to IE and has a small and statistically significant effect when compared to UC, regardless of the patient reported outcome measure used or the total volume of exercise prescribed. GE may be an appropriate option for people with PD to improve their QoL.
