Os efeitos da atividade física baseada em movimentos de dança no movimento, funções executivas, episódios depressivos e qualidade de vida de pessoas com doença de Parkinson

Abstract

Parkinson's disease is considered the second most frequent neurodegenerative disease in the world and is characterized by being chronic and progressive. Motor symptoms are understood, but non-motor symptoms may be present and appear at different temporal stages of the disease. Although pharmacological treatments are important to alleviate PD symptoms, they are still limited and most often trigger side effects. Therefore, therapeutic approaches that complement the pharmacological approach are increasingly being investigated to assess their possible beneficial effects on symptomatology and disease progression. Physical activity based on dance movements is emerging as a therapeutic approach to a range of PD symptoms as it is a multidimensional activity that requires rhythmic synchronization and more neuromuscular functions. To evaluate the effects of physical activity based on dance movements on movement, executive functions, depressive episodes and quality of life in individuals diagnosed with PD. 13 individuals with PD (8♀ 5♂), aged 65.9 ± 6.5 years (mean ± SD), Hoehn & Yahr stages I to III, MDS-UPDRS 67.62 ± 20.83 (mean ± SD) performed two weekly sessions (50 min/session) of physical activity based on dance movements for six months. The assessment protocols were performed pre and post-intervention, applying the POMA test to assess movement, the FAB test to assess executive function and subdomains, the MADRS test to assess depressive episodes, the PDQ-39 questionnaire to assess the perception of quality of life and, finally, the MDS-UPDRS scale to assess the severity of PD. Student's t test was used to compare pre- and post-intervention results of physical activity based on dance movements. The significance level was 95% (p < 0.05). We observed significant improvement in balance and gait by the POMA test, t (12) = 2.283, p = 0.0207. Executive function by the FAB test, t (12) = 2.840, p = 0.0074, abstract reasoning and inhibitory control by the subdomains of the FAB Conceptualization test, t (12) = 2.941, p = 0.0062, and Inhibitory Control, t (12) = 2.920, p = 0.0064, showed significant improvements between the pre- and post-intervention periods of physical activity based on dance movements. Depressive episodes assessed by the MADRS test significantly reduced, t (12) = 2.264, p = 0.0214, and the perception of quality of life by the PDQ-39 had a significant increase after physical activity based on dance movements, t (12) = 4.239, p = 0.0006. We did not observe significant changes in PD severity. Physical activity based on dance movements has shown to have attenuating potential in movement, executive functions, depressive episodes and quality of life in PD, and may be effective in future rehabilitation. The characteristic elements of physical activity based on dance movements such as rhythmic synchronization, more cognitive-motor integration and social skills may have contributed to the results obtained in this study.
