Objective: To explore the effects of Dance Therapy (DT) and Traditional Rehabilitation (TR) on both motor and cognitive domains in Parkinson's Disease patients (PD) with postural instability.
Methods: Sixteen PD patients with recent history of falls were divided in two groups (Dance Therapy, DT and Traditional Rehabilitation, TR); nine patients received 1-hour DT classes twice per week, completing 20 lessons within 10 weeks; seven patients received a similar cycle of 20 group sessions of 60 minutes TR. Motor (Berg Balance Scale - BBS, Gait Dynamic Index - GDI, Timed Up and Go Test - TUG, 4 Square-Step Test - 4SST, 6-Minute Walking Test - 6MWT) and cognitive measures (Frontal Assessment Battery - FAB, Trail Making Test A & B - TMT A&B, Stroop Test) were tested at baseline, after the treatment completion and after 8-week follow-up.
Results: In the DT group, but not in the TR group, motor and cognitive outcomes significantly improved after treatment and retained after follow-up. Significant changes were found for 6MWT (p = 0.028), TUG (p = 0.007), TMT-A (p = 0.014) and TMT-B (p = 0.036).
Conclusions: DT is an unconventional physical therapy for PD patients which effectively impacts on motor (endurance and risk of falls) and non-motor functions (executive functions).
