OBJECTIVES: To assess whether a specific land-based physical intervention with the inclusion of aquatic therapy is more effective than land-based rehabilitation alone for the treatment of balance dysfunction in patients with Parkinson disease (PD), immediately after therapy and at 6 months' follow-up. DESIGN: Randomized controlled study with 6-month follow-up. SETTING: A PD and brain injury rehabilitation department in a general hospital. PARTICIPANTS: Patients (n = 34) with moderate-stage PD. INTERVENTION: Seventeen patients underwent a land-based rehabilitation protocol called multidisciplinary intensive rehabilitation treatment (MIRT), and 17 underwent MIRT plus aquatic therapy (MIRT-AT). MAIN OUTCOME MEASURES: The primary outcome measure was the Berg Balance Scale (BBS); secondary outcome measures were the Unified Parkinson Disease Rating Scale parts II and III (UPDRS II/III) and the Timed Up and Go (TUG) test. These measures were assessed in both groups at admission, at discharge, and after 6 months. RESULTS: BBS improved after treatment in both groups. Even though no statistically significant difference between groups was observed at each observation time, BBS scores at follow-up were significantly higher than at baseline in MIRT-AT patients. Both groups also showed an improvement in UPDRS II/III and TUG at the end of treatment compared with baseline, but these findings were lost at the 6-month follow-up. CONCLUSIONS: Aquatic therapy added to land-based rehabilitation could provide a contribution to the treatment of balance dysfunction in patients with moderate-stage PD.
