Can Dance Improve Turning in People With Parkinson's Disease?

Objective: To investigate the effects of a dance intervention on selected functional parameters during the 180 degrees turning phase of the Timed Up & Go (TUG) test in people with Parkinson's Disease (PwPD). Methods: Fifteen adults clinically diagnosed with idiopathic PD were allocated into dance intervention (DIG; n = 7 ; age 73 +/- 2 years) and control (CG; n = 8; age 64 +/- 5 years) groups. The dance intervention lasted for 3 months (1 hour, twice a week). At baseline, all participants completed the Unified PD Rating Scale-part III, the International Physical Activity Questionnaire-short form, and the Hoehn & Yahr scale. Pre- and post-intervention, the primary outcomes were measured (number of steps and time to complete the 180 degrees turning phase of the TUG test) at 2 speeds (comfortable walking and as quickly and safely speed) while using the Xsens (R) 3D motion suit. The secondary outcome (girdle dissociation) was assessed by calculating the difference between pelvis and affected shoulder orientation in the transverse plane (dissociation angles) at each data point during the TUG test's 180 degrees turning phase. Results: At participant's comfortable walking speed, the functionality during the 180 degrees turning remained unaffected following the dance intervention. However, at participant's fast speed, the dance intervention group significantly reduced the number of steps with a large effect size, and the total time taken to complete the 180 degrees turning with a medium effect size. Post-intervention, most participants in the dance intervention group reduced the affected shoulder and pelvic girdle dissociation and turned more "en bloc." Conclusion: Dance can improve selected functional parameters during the 180 degrees turning at fast speed in PwPD. The current results should be considered in rehabilitation programs.
