Relaxation guided imagery reduces motor fluctuations in Parkinson's disease.

BACKGROUND

Motor fluctuations in Parkinson's disease (PD) cause major disabling symptoms.

OBJECTIVE

We aimed to assess the efficacy of relaxation guided imagery in PD patients with motor fluctuation.

METHODS

In a prospective pilot, case cohort, PD patients underwent (i) a relaxation session with relaxation guided imagery, and (ii) a control session of relaxing music. Three-day diaries were completed at baseline and after each intervention. Subsequently, patients received discs for home listening-a relaxation guided imagery disc and a relaxing music disc. After three months the patients were interviewed by phone.

RESULTS

Twenty one PD patients participated and 19 completed this study. There was a significant increase in the percent of "on" time after listening to the relaxation guided imagery disc as compared with baseline (from 47.7% to 62.8%, 95% CI 5.26-25.03, p = 0.005). Relaxing music caused no significant change in percent of "on" time from baseline (from 47.7% to 53.0%, p = 0.161). Although all sessions were performed in "on" state, there was a significant decrease in UPDRS motor subscores after each of the two sessions as compared with the UPDRS score before the session (relaxation guided imagery mean reduction -3.81 p = 0.0002 and after relaxing music mean reduction -1.95, p = 0.001), significantly more so after the relaxation guided imagery (p = 0.020). After 3 months listening to the relaxation guided imagery disc increased "on" time from baseline by 12.6% (95% CI 3.19-28.39, p = 0.111) but this did not reach statistical significance.

CONCLUSION

In this pilot study we showed that relaxation guided imagery is a promising treatment for PD.
