“…Different combinations of factors including demographic characteristics, disease severity, fall history, fear of falling, other gait and mobility measures, freezing of gait, balance, balance confidence, muscle power, cognition, and depression, have been identified as significant predictors (explaining up to 30-73% of variance) of gait and mobility performance in single and dual task conditions (Varalta et al, 2015; Rochester et al, 2008; Falvo & Earhart, 2009; Lord et al, 2010; Paul et al, 2013; Stegemöller et al, 2014; Lord et al, 2014; Strouwen et al, 2016; Nemanich et al, 2013). All except one of these previous studies measured participants while on anti-parkinson medication, and the single study testing ‘off’ medication included a relatively small sample (Lord et al, 2010).…”

Mobility and gait limitations are major issues for people with Parkinson disease (PD). Identification of factors that contribute to these impairments may inform treatment and intervention strategies. In this study we investigated factors that predict mobility and gait impairment in PD. Participants with mild to moderate PD and without dementia (n=114) were tested in one session ‘off’ medication. Mobility measures included the 6-Minute Walk test and Timed-Up-and-Go. Gait velocity was collected in four conditions: forward preferred speed, forward dual task, forward fast as possible and backward walking. The predictors analyzed were age, gender, disease severity, balance, balance confidence, fall history, self-reported physical activity, and executive function. Multiple regression models were used to assess the relationships between predictors and outcomes. The predictors, in different combinations for each outcome measure, explained 55.7% to 66.9% of variability for mobility and 39.5% to 52.8% for gait velocity. Balance was the most relevant factor (explaining up to 54.1% of variance in mobility and up to 45.6% in gait velocity). Balance confidence contributed to a lesser extent (2.0% to 8.2% of variance) in all models. Age explained a small percentage of variance in mobility and gait velocity (up to 2.9%). Executive function explained 3.0% of variance during forward walking only. The strong predictive relationships between balance deficits and mobility and gait impairment suggest targeting balance deficits may be particularly important for improving mobility and gait in people with PD, regardless of an individual’s age, disease severity, fall history, or other demographic features.

“…Cognitive tasks, when associated with motor tasks, cause major disturbance in PD patients. Such negative cognitive-motor interaction is documented in balance and gait in PD patients 15,16,17,18 . Many studies have found the effect of sensory disturbance in static balance, but few evaluated the cognitive task addition effect.…”

“…Changes on postural control due to sensory disturbance have been well described, such as changes on gait parameters in dual-task conditions, for both healthy elderly and PD patients 16,17 . However, our results add interesting data, because they showed that the competition with a concurrent cognitive activity disrupted posturographic measures in a different manner than visual deprivation.…”

Objectives: To estimate the impact of a sensory-motor-cognitive task on postural balance, in Parkinson disease patients (Hoehn and Yahr 2-3) and to investigate possible relationships between posturography and functional balance clinical scales. Method: Parkinson disease patients (n = 40) and healthy controls (n = 27) were evaluated with fluency tests, Berg Balance scale, Mini Best test and static posturography on the conditions eyes open, eyes closed and dual-task (simultaneous balance and fluency tasks). Results: Posturographic data showed that Parkinson disease patients performed worse than controls in all evaluations. In general, balance on dual-task was significantly poorer than balance with eyes closed. Posturographic data were weakly correlated to clinical balance scales. Conclusion: In clinical practice, Parkinson disease patients are commonly assessed with eyes closed, to sensitize balance. Our study showed that adding a cognitive task is even more effective. Static posturographic data should be carefully overgeneralized to infer functional balance impairments.

Pereira JAC, Gaiad TP, Santos AP. Efeito do treinamento em circuito orientado para tarefa sobre o desempenho motor e a qualidade de vida de pacientes com doença de Parkinson: um estudo de casos. Rev Ter Ocup Univ São Paulo. 2016 set.-dez.;27(3):329-35. RESUMO:Este estudo trata da descrição de dois casos de pacientes com doença de Parkinson (DP) submetidos a um programa de reabilitação diferencial, composto de treinamento em circuito orientado para tarefa. O objetivo foi analisar os possíveis benefícios do tratamento sobre o desempenho motor e a qualidade de vida em indivíduos com DP. O circuito foi constituído por cinco estações direcionadas à funcionalidade, equilíbrio e destreza manual. Foi desenvolvido durante seis semanas. Para a avaliação foram utilizados os testes de Romberg sensibilizado, velocidade da marcha e Timed Up & Go; o questionário PDQ-39 para avaliar a qualidade de vida e a escala unificada para a avaliação da doença de Parkinson (UPDRS). O tempo gasto em cada estação e o tempo total para completar o circuito foi cronometrado nas doze sessões para análise do desempenho dos pacientes. Os dois pacientes apresentaram melhora em todos os testes avaliados, na pontuação do PDQ-39 e na escala UPDRS, além disso, houve melhora no desempenho motor em todas as estações propostas, observada através da qualidade da execução da atividade e da diminuição do tempo para executá-la. O tratamento utilizando circuito pode ser benéfico para pacientes com DP. ABSTRACT: This study deals with the description of two cases of patients with Parkinson's disease (PD) submitted to a differential rehabilitation program compound of taskoriented circuit training. The aim was to analyze the benefits of treatment on motor performance and quality of life in individuals with PD. The circuit consisted of five stations aimed at functionality, balance and manual dexterity. It was developed for six weeks. For the assessment was used Romberg tests sensitized, gait speed and Timed Up & Go; PDQ-39 questionnaire to assess quality of life and the unified Parkinson's disease rating scale (UPDRS) to assess the symptoms of PD were performed before and after treatment. The time spent in each stations and the total time to complete the circuit was timed in twelve sessions for analysis of the performance of patients. Both patients showed improvement in all evaluated tests, the score of the PDQ-39 and UPDRS, moreover, there was an improvement in motor performance in all proposed stations observed by the activity execution quality and decreasing of time to run it. The treatment using the circuit can be beneficial for patients with PD.

Abstract: Different characteristics of gait are related to distinct types of cognitive processing, which may be differentially affected by dual-task walking due to the pathology of PD.
