The effects of Brazilian dance, deep-water exercise and nordic walking, pre- and post-12 weeks, on functional-motor and non-motor symptoms in trained PwPD.

BACKGROUND: Motor and non-motor symptoms affect functional autonomy, mobility and daily life activities in People with Parkinson's Disease (PwPD). Brazilian Dance (BD), Deep-water exercise (DWE), and Nordic Walking (NW) are well-accepted, low-cost, and safe non-pharmacological strategies for untrained PwPD. However, no previous studies have investigated and compared the effects of these interventions on trained PwPD. OBJECTIVE: To describe and compare the effects of BD, DWE and NW, pre- and post-12 weeks, on functional-motor and non-motor symptoms in trained PwPD. METHODS: Eighty-three trained PwPD were randomly assigned into three groups: BD (n = 31), DWE (n = 21) and NW (n = 31), that participated in one of the interventions for 12 weeks. We applied Timed up and go at two speeds (self-selected and fast); 6-min and 10-meter walk test; Sit-to-Stand and handgrip test; Unified Parkinson Disease Rating Scale - III; Falls Efficacy Scale; Montreal Cognitive Assessment questionnaire; and Parkinson's Disease Questionnaire-39. The main (group and time) and interaction effects were analyzed using GEE analysis (p<0.05). RESULTS: Statistical differences were found between groups in the handgrip test (p<0.01), the time (p = 0.04), and interaction group*time (p< 0.01) in the Sit-to-stand test. While BD improved the Sit-to-stand test performance (ES=1.00; large effect size), DWE and NW remained unchanged (ES=0.16 and ES=0.14; low effect size). CONCLUSION: BD, DWE, and NW maintained most of the functional-motor and non-motor symptoms in trained PwPD. BD was shown to be more effective at improving strength in the lower limbs, when compared to NW and DWE.

Samba, deep water, and poles: a framework for exercise prescription in Parkinson's disease.

Parkinson's disease is a brain disorder that leads to tremor, slowness, muscle stiffness, and other movement disorders. The benefits of exercise for reducing disability in individuals with Parkinson's disease are numerous. However, not much is known about the designing and prescription of exercise in neurodegenerative diseases. A brief review and indications for exercise prescription and evaluation are discussed throughout. In this scoping review, we specifically aimed to describe the applicability of walking tests (6-min/10-m) for the prescription of exercise in individuals with Parkinson's disease and to propose training (undulating periodized) designs in three exercise modalities, Brazilian dance rhythms (Samba and Forró), deep-water exercises, and Nordic walking. These training models and evaluation methods may assist coaches and therapists in organizing exercise programs adequate to people with Parkinson's disease, and are essential steps toward a comprehensive and more detailed understanding of the training loads in motor disorders and disease states.

Can Samba and Forró Brazilian rhythmic dance be more effective than walking in improving functional mobility and spatiotemporal gait parameters in patients with Parkinson's disease?

BACKGROUND: Parkinson's disease (PD) causes motor and nonmotor disorders in patients. Unlike aerobic training, potential adaptations from the practice of dance are less understood in PD, particularly compared with better known exercise modes. This study aimed to verify and compare the effects of a Brazilian dance program, inspired by Samba and Forrró rhythms, and a walking program on functional mobility and spatiotemporal gait parameters in patients with PD. METHODS: Eighteen participants with PD were divided into a dance group (DG) and a walking group (WG) and were assessed before and after an intervention period of 24 1-h sessions, performed twice per week for 12 weeks. The timed-up-and-go test (TUG) and walking kinematics at self-selected speed (SSS) and fast speed (FS) were determined. The generalized estimating equation method was used to compare the DG and WG pre- and post-intervention and to evaluate the group*time interaction (α <  0.05). RESULTS: Both groups demonstrated a significant improvement in TUG test at SSS (p = 0.02; effect size [ES] = 0.42) and FS (p = 0.02; ES = 0.24). In general, spatiotemporal parameters remained unchanged, except at SSS, in which the DG increased the stride frequency (p = 0.011; ES = 0.72). At FS, the swing time demonstrated a significant group*time interaction (p <  0.001; ES = 1.10), in which the two groups exhibited different behaviors: DG decreased (p = 0.015) and WG increased (p = 0.012). CONCLUSIONS: Functional mobility improved similarly in both groups. The results suggest that a 12-week program of Brazilian dance was sufficient to produce improvements in functional mobility and gait in individuals with PD.
