Does physiotherapy plus cognitive training improve balance in Parkinsons disease? Randomized clinical trial

Abstract Aims: Postural instability is intrinsically related to cognitive dysfunctions in Parkinson's disease (PD), which supports the importance of multimodal treatments. The purpose of this study was to investigate the effectiveness of adding cognitive training to motor physiotherapy in comparison with motor physiotherapy in the balance of individuals with PD. Methods: randomized clinical trial, where the individuals were randomized to two treatments: Physiotherapy Group (PG; n=29; M=12; HY= 2.5 [2-3]) executed balance training; Physiotherapy plus Cognitive Training Group (PCG; n=29; 10M; HY= 2.5 [1.5-3]), balance training plus a cognitive training at the end of the therapy. Evaluation instruments: Balance Evaluation Systems Test (BESTest); Unified Parkinson Disease Rating Scale (UPDRS). Results: The intragroup analysis revealed that both groups presented improved balance and UPDRS total score after execution of the protocols, but without statistically significant intergroup differences. The effect sizes were small for all the comparisons. Conclusion: There was no difference between the proposed treatments (PCG and PG). However, both interventions benefitted the individuals' balance and signs and symptoms of PD, when considered the time effect.

Efficacy of neurofunctional versus resistance training in improving gait and quality of life among patients with Parkinson's disease: a randomized clinical trial

Abstract AIMS to compare the efficacy of neurofunctional training versus resistance training in improving gait and quality of life among patients with PD METHODS This randomized controlled trial included 40 participants randomly assigned to two groups through random number table generator: resistance training (RT) (n=19) and neurofunctional training (NT) (n=21). The RT group performed resistance exercises emphasizing the lower limbs and trunk, while the NT group sessions were focused on gait, functional independence and balance training. Trained physical therapists supervised both groups. The training sessions lasted 60 minutes in each group and were performed twice a week, totalizing 24 sessions. The outcomes, gait and quality of life, were measured using video gait analysis and footprint analysis; and PDQL and PDQ-39 questionnaires, respectively RESULTS intra-group comparison revealed all gait variables (stride length, step length, number of steps, time of distance walked, gait speed and cadence) improved after the NT intervention with large effect size, while only stride length improved in the RT group with moderate effect size. The between group analyses means (Δ) shows that all the variables presented statistically significant differences in the NT group. Additionally, both groups showed significant improvements in quality of life. CONCLUSIONS The application of specific neurofunctional training, directed and enriched with sensorial resources, resulted in superior gait performance among individuals with PD when compared to those in the resistance training group; both treatments were efficacious in improving quality of life.

Desempenho cognitivo-perceptual de indivíduos com doença de Parkinson submetidos à fisioterapia / Cognitive-perceptual performance of subjects with Parkinson's disease submitted to physiotherapy

Objetivo: Verificar a efetividade da fisioterapia no sistema cognitivo-perceptual de indivíduos com doença de Parkinson (DP). Métodos: Trata-se de série de casos prospectiva, composta por 16 indivíduos com DP, entre os estágios 1,5 a 3 na escala de Hoehn e Yahr modificada (HY), avaliados antes, ao final e três meses pós-intervenção (follow up) utilizando-se os seguintes instrumentos: Escala Unificada para Avaliação da DP, Escala de Estadiamento HY modificada, Escala de Depressão Geriátrica (GDS), Mini-exame do estado mental (MEEM), Índice de Katz e duas ilustrações visomotoras. Receberam intervenção fisioterapêutica totalizando 20 sessões visando a melhora do sistema cognitivo-perceptual. Resultados: Foram encontradas diferenças estatisticamente significantes entre os valores pré e pós (P=0,03) e entre o pós e o follow up (P=0,03) para a execução das duas ilustrações visomotoras. Quanto aos demais desfechos não foram encontradas diferenças significantes. Conclusão: A intervenção realizada foi efetiva para o sistema perceptual em indivíduos com DP. Entretanto, não foram observadas diferenças estatisticamente significantes entre os valores dos três momentos de avaliação nas escalas MEEM, GDS e Índice de Katz.

Objective: To investigate the effectiveness of physiotherapy in the cognitive-perceptual system of individuals with Parkinson's disease. Methods: This is a prospective case series, consisting of 16 individuals with PD between stages 1.5 to 3 on the Hoehn and Yahr scale, assessed before, at the end, and later than three months after the intervention (follow up) using the following instruments: Unified Parkinson's Disease Rating Scale, Degree of Disability Scale of Hoehn and Yahr, Geriatric Depression Scale, Mini Mental Test, the Katz Index, and two visuomotor graphics. A physiotherapy intervention, totaling 20 sessions targeting the improvement of cognitive-perceptual system, was received. Results: Statistically significant differences were found between pre and post (P=0.03) and between post and follow up (P=0.03) for the implementation of the two visuomotor graphics. As for the other outcomes, no significant differences were found. Conclusion: The intervention was made effective for the perceptual system in individuals with PD. However, no statistically significant differences were found between the values of the three evaluation moments in the MMSE scale, GDS and Katz Index.

Efetividade da fisioterapia associada à dança em idosos saudáveis: ensaio clínico aleatório / Effectiveness of physical therapy in association with dance in healthy elderly: a randomized clinical trial

Objetivo: verificar a efetividade da fisioterapia associada à dança em idosos saudáveis nos desfechos "equilíbrio", "flexibilidade" e "agilidade". Métodos: ensaio clínico aleatório, no qual a amostra foi composta por 22 indivíduos e posteriormente aleatorizada em dois grupos: controle (GC; 7M/4H; idade= 74,1±7,3; n=11) e intervenção (GI; 9M/2H; idade= 75,7±7,8; n=11). Os grupos foram submetidos às seguintes avaliações realizadas no período pré e pós-intervenção: avaliação do equilíbrio pela Escala de Berg, agilidade pelo Timed Up and Go test e flexibilidade pelo Banco de Wells (janela aberta e fechada). Foi proposto um programa de intervenção fisioterápica associada à dançaterapia composto por 16 terapias com duração de 60 minutos e frequência de duas vezes semanais. A intervenção seguiu um protocolo de evolução baseado na complexidade dos exercícios e teve como principais objetivos estimular equilíbrio, independência funcional e alongamento muscular. A análise estatística foi realizada pelo programa SPSS 15.0. Foram utilizados os testes de Mann-Whitney para a comparação dos grupos e Wilcoxon para comparar os momentos pré e pós-intervenção, com significância estatística de 5%. Resultados: o grupo intervenção apresentou melhora do equilíbrio (p=0,04), flexibilidade (p=0,01) e agilidade (p=0,03) em relação ao grupo controle. O grupo controle apresentou melhora nos níveis de flexibilidade (p=0,01). Conclusão: o programa proposto se mostrou efetivo para melhora do equilíbrio, flexibilidade e agilidade nos indivíduos submetidos à intervenção.
