Dual-task exercise as a therapy for executive motor function in Parkinson's disease

Abstract

Purpose. To evaluate the effects of aerobic exercise with dual-task on the motor function in patients with Parkinson's disease. Methods. Clinically evaluated by the Unified Parkinson's Disease Rating Scale -III and the Senior Fitness Test battery, 20 patients with Parkinson's disease were randomly divided into a control and an experimental group, with the latter performing a 4-week program of water-walking in a deep pool while executing dual-tasks. Evaluations were made before and after 4 weeks in both groups. Results. Patients with Parkinson's disease revealed significant improvements in pre-/post-exercise motor function, with a moderate effect (p < 0.001; d = 0.44). Bradykinesia (p < 0.001) and agility (p < 0.001) exhibited significant changes individually. Conclusions. Regular exercise combined with executive challenge such as dual-task may counteract the advanced motor symptoms of Parkinson's disease neurodegeneration.
