RESUMEN
Objectives: Parkinson's disease (PD) is a neurodegenerative disorder that impacts the dopaminergic neurons of the substantia nigra, leading to motor and non-motor symptoms, as well as changes in activities of daily living (ADL) and quality of life (QoL). Aquatic physical exercises and dual-task physical exercises have been used to manage PD symptoms. The aim of this study was to investigate the effects of a dual-task aquatic exercise program on the ADL, motor symptoms, and QoL of individuals with PD. Methods: A randomized controlled trial with a parallel group design was employed, and participants were randomized into 2 groups: a control group and an experimental group. The intervention was a 10-week program consisting of twice-weekly 40-minute aquatic dual-task exercises. Pre-intervention evaluations of ADL, motor function, and QoL were conducted at baseline (AS1), immediately after the intervention (AS2), and 3 months post-intervention (follow-up-AS3). The Unified Parkinson's Disease Rating Scale (UPDRS) II and III sections and the Parkinson's Disease Questionnaire 39 (PDQ-39) were utilized for outcome measures. Results: A total of 25 individuals completed the study. The experimental group showed significant improvements in both the UPDRS II (ADL) and III (motor function) sections (P's < .05), but there was no significant difference in PDQ-39 scores. Additionally, significant differences were observed in the experimental group between the AS2 and AS3 time periods (P < .05) for both UPDRS II and III scores (P < .05). Conclusions: Aquatic dual-task training may be effective in improving both ADL and motor functions in individuals with PD. Furthermore, the combination of aquatic environment and dual-task exercises may represent a promising approach to maintaining and improving the functionality of individuals with PD.
RESUMEN
OBJECTIVE: Analyze the effects of a multicomponent aquatic exercise program on motor aspects, functional mobility, muscle function and aquatic motor skills of people with PD. METHODS: Eighteen people with a PD diagnosis were assessed before and after a 12-week multicomponent aquatic exercise program, twice a week, with each session lasting 50 min. The terrestrial variables analyzed were motor aspects, through the Unified Parkinson Disease Rating Scale (UPDRS); functional mobility, through the Five Times Sit to Stand Test (FTSST); Peak Torque (PT) and Mean Power (MP) of hip, knee and ankle flexors and extensors, assessed using an isokinetic dynamometer. In water, aquatic motor skill levels were assessed by means of the Aquatic Functional Assessment Scale (AFAS). RESULTS: Significant improvements were found after the intervention in the following outcomes: motor aspects (p = 0.038, Δ = 5-61); MP of knee flexors at 90°/s on the most affected side (p = 0.026, Δ = 5.14), MP of knee extensors at 90°/s on the most affected side (p = 0.008, Δ = 8.69), MP of knee extensors at 120°/s on the most affected side (p = 0.005, Δ = 8.35), and AFAS in the domain of specialized therapeutic exercises (p = 0.014, Δ = 1.28). CONCLUSIONS: The completed multicomponent aquatic exercise program promoted changes in muscle function and terrestrial and aquatic functional outcomes in people with PD.
