RESUMO

OBJECTIVES: This study compared electroencephalography microstates (EEG-MS) of patients with Parkinson's disease (PD) to healthy controls and correlated EEG-MS with motor and non-motor aspects of PD. METHODS: This cross-sectional exploratory study was conducted with patients with PD (n = 10) and healthy controls (n = 10) matched by sex and age. We recorded EEG-MS using 32 channels during eyes-closed and eyes-open conditions and analyzed the four classic EEG-MS maps (A, B, C, D). Clinical information (e.g., disease duration, medications, levodopa equivalent daily dose), motor (Movement Disorder Society - Unified Parkinson Disease Rating Scale II and III, Timed Up and Go simple and dual-task, and Mini-Balance Evaluation Systems Test) and non-motor aspects (Mini-Mental State Exam [MMSE], verbal fluency, Hospital Anxiety and Depression Scale, and Parkinson's Disease Questionnaire-39 [PDQ-39]) were assessed in the PD group. Mann-Whitney U test was used to compare groups, and Spearman's correlation coefficient to analyze the correlations between coverage of EEG-MS and clinical aspects of PD. RESULTS: The PD group showed a shorter duration of EEG-MS C in the eyes-closed condition than the control group. We observed correlations (rho = 0.64 to 0.82) between EEG-MS B, C, and D and non-motor aspects of PD (MMSE, verbal fluency, PDQ-39, and levodopa equivalent daily dose). CONCLUSION: Alterations in EEG-MS and correlations between topographies and cognitive aspects, quality of life, and medication dose indicate that EEG could be used as a PD biomarker. Future studies should investigate these associations using a longitudinal design.

RESUMO

Background: Self-reported clinical worsening by people with Parkinson's disease (PD) during social distancing may be aggravated in Brazil, where the e/tele-health system is precarious. Objectives: This study aims to investigate self-reported changes in motor and non-motor aspects during social distancing in people with PD living in Brazil and to investigate the factors that might explain these changes. Methods: In this multicenter cross-sectional trial, 478 people with a diagnosis of idiopathic PD (mean age = 67, SD = 9.5; 167 female) were recruited from 14 centers distributed throughout the five geographical regions of Brazil. The evaluators from each center applied a questionnaire by telephone, which included questions (previous and current period of social distancing) about the motor and non-motor experiences of daily living, quality of life, daily routine, and physical activity volume. Results: Self-reported clinical worsening in non-motor and motor aspects of daily life experiences (Movement Disorder Society-Unified PD Rating Scale-parts IB and II-emotional and mental health, and fear of falling) and in the quality of life was observed. Only 31% of the participants reported a guided home-based physical activity with distance supervision. Perceived changes in the quality of life, freezing of gait, decreased physical activity volume, daily routine, and fear of falling explained the self-reported clinical worsening (P < 0.05). Conclusions: Self-reported clinical worsening in people with PD living in Brazil during social distancing can also be aggravated by the precarious e/tele-health system, as perception of decreased physical activity volume and impoverishment in daily routine were some of the explanatory factors. Considering the multifaceted worsening, the implementation of a remote multi-professional support for these people is urgent.

RESUMO

Patients with Parkinson's disease (PD) have difficulties while performing dual-task activities, a condition present in everyday life. It is possible that strategies such as transcranial Direct Current Stimulation (tDCS) can be associated with motor training enriched with dual-task training to improve the performance of two concurrent tasks. Currently, it is unclear whether specific tasks and clinical conditions of PD patients have different results after the intervention. Therefore, the proposed randomized controlled trial will examine task-dependency in enhancing the effects of tDCS-linked rehabilitation training on PD and the relationships between baseline outcomes in responders and non-responders to therapy. Fifty-six patients with Parkinson's disease will be recruited to participate in this controlled, double-blind randomized multicentric clinical trial. Patients in modified Hoehn & Yahr stage 1.5-3, age between 40 and 70 years will be included. Subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform treadmill gait training associated with dual task exercises+tDCS, while the CG will only engage in treadmill gait training+tDCS. Blinded testers will assess patients before and after 12 intervention sessions and after a 4-week follow-up period. All patients will undergo a screening and an initial visit before being assessed for primary and secondary outcomes. The primary outcome measure is functional mobility measured by Timed Up and Go Test. Secondary outcomes include cognitive function, participation, motor function and body function and structure. This study will evaluate the effectiveness of an intervention protocol with tDCS, dual-task training and gait training in patients with PD. The study will also highlight the clinical factors and variability between individuals that could interfere in the training of a specific task and influence the therapeutic effect.

RESUMO

OBJECTIVE: To understand the perception of children with disabilities and their families regarding factors that interfere with participation in leisure activities in Brazil. METHODS: This qualitative study included 14 focus groups, involving a total of 80 participants (40 children with disabilities and 40 family members). Discus-sions were recorded and transcribed. Coding was based on the International Classification of Functioning Disability and Health, following linking rules. RESULTS: A total of 80 individuals participated in the study. For parents and children the most-cited barriers to participation in leisure activities were relat-ed to environmental factors. For children, the main barriers were the attitudes of their nuclear family, acquaintances, and friends. Access to products and technology for personal mobility were also important obstacles. For them, support from immediate family was both a facilitator and barrier. Other barriers identified by family members were open-space planning services and assets. As facilitators, the atti-tudes and support of people in positions of authority also were reported by this group. CONCLUSION: For parents and children, most disabling barriers were related to environmental factors, such as access to products and technology, support, and attitudes. Some differences in perception were observed between comments from children and parents; for example, regarding barriers due to immediate family. Parents showed greater awareness of barriers and facilitators to participation in leisure activities.

RESUMO

OBJECTIVE: The aim of the study was to evaluate the effects of adding load to restrain the nonparetic lower limb during gait training on weight-bearing and temporal asymmetry after stroke. DESIGN: Thirty-eight subjects were randomized into treadmill training with load (5% of body weight) on the nonparetic limb (experimental group) and treadmill training without load (control group). Interventions lasted 30 mins/d for 2 wks (9 sessions). Both groups performed home-based exercises and were instructed to increase the use of paretic limb in daily life situations. Ground reaction force was obtained by a force plate during standing position (static) and gait (dynamic). Temporal gait parameters were assessed by a motion system analysis. Outcome measures were evaluated at baseline, posttraining, and after a 40-day follow-up. RESULTS: The experimental group increased static ground reaction force of the paretic limb at posttraining (P = 0.037) and the control group increased dynamic ground reaction force of the paretic limb at posttraining (P = 0.021), both with maintenance at follow-up. Neither group showed a change in the swing time symmetry ratio after training (P = 0.190). CONCLUSIONS: Treadmill training associated with behavioral strategies/home-based exercises seemed to be useful to minimize weight-bearing asymmetry, but not to improve temporal gait asymmetry. Load addition did not show additional benefits.

RESUMO

BACKGROUND: Gait disorders in individuals with Parkinson's disease (PD) may be associated with alterations in the motor control system and aggravated by psychoemotional and cognitive issues. Therapeutic strategies aimed at self-perception and motor regulation seem to be promising. Motor imagery (MI) has been shown to be one of these strategies, but there is still no clear evidence of its applicability in this population. The aim of this trial is to determine the effects of motor-imagery training on the gait and electroencephalographic activity of individuals with PD. METHODS/DESIGN: The sample will consist of 40 individuals, aged between 45 and 75 years, in the mild and moderate phase of the disease, with the ability to generate voluntary mental images. They will be assessed for cognitive level, degree of physical disability, mental-image clarity, kinematic gait variables, electroencephalographic activity and mobility. Next, subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform motor imagery and gait, while the CG will only engage in gait exercises. Twelve training sessions will be conducted lasting up to 90 min each, three times a week, for 4 weeks. The subjects will be reassessed on the kinematic variables of gait, electroencephalographic activity and mobility at 1, 7 and 30 days after the final training session. DISCUSSION: The results may provide an important advance in neurological rehabilitation where an easy-access and low-cost intervention may help to improve gait, electroencephalographic activity and mobility in individuals with PD.

RESUMO

OBJECTIVES: To identify the factors affecting the use of physiotherapy services among individuals with Parkinson's disease (PD) living in Brazil. METHODS: Overall, 479 individuals with idiopathic PD, of both sexes, at any stage of the Hoehn & Yahr (HY) scale, and from seven capital cities in Brazil were recruited from 2014 to 2016. Multivariate logistic regression was the main statistical tool. For the construction of the logistic model, the association of the dependent variable "physiotherapy" with the independent sociodemographic/economic and clinical variables: age, education, family income, time of PD since onset, HY, the activities of daily living and motor subscales of the Unified Parkinson's Disease Rating Scale, cognitive aspects, depressive symptoms, fear of falling, freezing gait, history of falls, physical activity level, gait speed, walking performance and balance, were verified. RESULTS: The 479 individuals had an average age of 65.2 ± 11.0 years, 88% were in the HY I-III stages and 43.4% were under physiotherapy treatment. The analysis identified two determinant variables related to the use of the physiotherapy service: level of education (OR = 1.24) and walking performance (OR = 0.82). Decreased walking performance and a higher educational level increased the use of a physiotherapy service in individuals with PD living in Brazil. CONCLUSIONS: The present study shows that individuals with PD, residents from different regions of Brazil, have limited access to physiotherapy services. In addition, the Brazilian Public Health Care System, as well as local programs, need to target PD individuals with a low educational level to improve their access to physiotherapy services. Goals should aim towards the development of physical exercise programs to improve the patients' functional performance for a longer period.

RESUMO Descrever a utilização do serviço de fisioterapia e identificar os fatores que determinam o uso desse serviço entre indivíduos com doença de Parkinson (DP) que vivem no Brasil. Métodos: No total, 479 indivíduos com DP idiopática, de ambos os sexos, em qualquer estágio da escala de Hoehn & Yahr (HY) e de sete capitais do Brasil foram recrutados durante 2014 a 2016. A análise de regressão logística multivariada foi a principal ferramenta de análise estatística. Para a construção do modelo logístico foi investigada a associação da variável dependente "fisioterapia" com variáveis independentes sociodemográficas, econômicas e clínicas: idade, educação, renda familiar, tempo de DP desde o início, HY, domínio motor e atividade de vida diária da Unified Parkinson´s Disease Rating Scale, aspectos cognitivos, sintomas depressivos, medo de queda, congelamento marcha, história de quedas, nível de atividade física, velocidade de marcha, capacidade de caminhar e equilíbrio. Resultados: 479 indivíduos apresentaram média de 65,2 ± 11,0 anos, 88% tiveram HY = I-III e 43,4% faziam fisioterapia para a DP. A análise identificou duas principais variáveis determinantes do uso da fisioterapia: educação (OR = 1,24) e capacidade de caminhada (OR = 0,82). A diminuição da capacidade de caminhar e maior nível educacional aumentam o uso da fisioterapia em indivíduos com doença de Parkinson vivendo no Brasil. Conclusões: O presente estudo mostra que indivíduos com DP, residentes de diferentes regiões do Brasil, têm acesso limitado aos serviços de fisioterapia. Além disso, o Sistema Brasileiro de Saúde Pública, bem como os programas locais, precisam atingir pessoas de DP com baixo nível educacional para melhorar seu acesso aos serviços de fisioterapia. Os objetivos devem ser para o desenvolvimento de programas de exercícios físicos para melhorar o desempenho funcional dos pacientes por um período mais longo.
