“…Compared with straight-line gait speed at a comfortable speed, circular gait time at a comfortable speed may be a more sensitive tool to detect the decline in mobility of older adults. A previous study reported that older adults aged >80 years had greater trunk and pelvis sway during walking on a foam surface compared with an old group aged up to 75 years, 24 suggesting that the disability of postural control during walking seems to progress even in old age. In the present study, it is considered that older individuals aged >75 years could not control their posture and coordinate their legs smoothly, 25 resulting in a slower circular gait speed.…”

The present study aimed to investigate the age-related changes in gait speeds and asymmetry during circular and straight-line gaits among older adults aged 60-79 years. Methods:The study included 391 community-dwelling older adults aged >60 years, who participated in the Nagahama cohort study. They were assigned to four age groups: 60-64 years (early 60s), 65-69 years (late 60s), 70-74 years (early 70s) and 75-79 years (late 70s). For the circular gait test, the time required to walk twice around a 1-m diameter circle for right and left rotations were measured. The average time of the two trials was measured as the circular gait time, and the side-to-side difference in the circular gait times was calculated as an asymmetry index. Walking speed, asymmetry of step length, and asymmetry of stance duration time during straightline gait at comfortable and maximal walking pace were measured.Results: Circular gait time in older women in the late 70s group was significantly slower than that in other age groups; however, no age-related change was observed in older men. Maximal gait speeds in the early and late 70s groups were significantly slower than those in the early 60s group.Conclusions: Age-related decline in circular gait speed was observed in older women aged ≥75 years, but not in older men. Maximal straight-line gait speed decreased significantly in both genders after the age of 70 years.

“…Gait speed may be used to identify elderly adults at increased risk of early mortality. Slower gait speed is associated with increased risk for falls, and each 10 cm/s decrease in gait speed was associated with a 17% increased risk of falls [ 32 ]. Gait speed is associated with survival among the elderly and reflects health and functional status.…”

BackgroundA robotic exoskeleton device is an intelligent system designed to improve gait performance and quality of life for the wearer. Robotic technology has developed rapidly in recent years, and several robot-assisted gait devices were developed to enhance gait function and activities of daily living in elderly adults and patients with gait disorders. In this study, we investigated the effects of the Gait-enhancing Mechatronic System (GEMS), a new wearable robotic hip-assist device developed by Samsung Electronics Co, Ltd., Korea, on gait performance and foot pressure distribution in elderly adults.MethodsThirty elderly adults who had no neurological or musculoskeletal abnormalities affecting gait participated in this study. A three-dimensional (3D) motion capture system, surface electromyography and the F-Scan system were used to collect data on spatiotemporal gait parameters, muscle activity and foot pressure distribution under three conditions: free gait without robot assistance (FG), robot-assisted gait with zero torque (RAG-Z) and robot-assisted gait (RAG).ResultsWe found increased gait speed, cadence, stride length and single support time in the RAG condition. Reduced rectus femoris and medial gastrocnemius muscle activity throughout the terminal stance phase and reduced effort of the medial gastrocnemius muscle throughout the pre-swing phase were also observed in the RAG condition. In addition, walking with the assistance of GEMS resulted in a significant increase in foot pressure distribution, specifically in maximum force and peak pressure of the total foot, medial masks, anterior masks and posterior masks.ConclusionThe results of the present study reveal that GEMS may present an alternative way of restoring age-related changes in gait such as gait instability with muscle weakness, reduced step force and lower foot pressure in elderly adults. In addition, GEMS improved gait performance by improving push-off power and walking speed and reducing muscle activity in the lower extremities.Trial registration NCT02843828.

“…Em contrapartida, os melhores achados em relação ao Conceito Balance também podem ser atribuídos a postulação de maiores esforços para a manutenção da estabilidade corporal, considerando parte de sua execução em superfície instável, o que garante maior necessidade de informações sensoriais 24 . Tal estudo também acrescenta ao referenciar que o treinamento em áreas complacentes favorece o tratamento de neuropatias periféricas, além de distúrbio sensório-motores relativos ao envelhecimento, assim como auxilia na detecção dos mesmos.…”

Resumo Objetivo: Avaliar sensibilidade, equilíbrio e qualidade de vida em diabéticos neuropatas, comparando os efeitos de dois protocolos de Fisioterapia. Método: Dez voluntários divididos em dois grupos -Grupo Fisioterapia Convencional (GC) e Grupo Balance (GB), submetidos a dois protocolos distintos com duração de 1 hora/dia, totalizando 12 sessões, avaliados em dois momentos pelos instrumentos: Teste de Marcha Tandem (TMT) e Escala de Equilíbrio de Berg (EEB) para o equilíbrio; estesiometria, a fim de delinear a sensibilidade periférica e a escala Neuroqol, para qualidade de vida (QV). A análise estatística foi realizada por meio dos testes T de Student e Qui-quadrado no pré e pós-tratamento (p≤0,05). Resultados: O GC obteve resultado significante no pós-tratamento somente na avaliação da EEB (p=0,03), enquanto o GB apresentou valores maiores no período pós-tratamento em todas as variáveis avaliadas, com melhoras quantitativas na sensibilidade (p=0,02), equilíbrio pelo TMT (p=0,03) e EEB (p=0,04), além da QV (p=0,04). No que diz respeito à comparação entre os grupos, os resultados significativos foram apenas para variáveis EEB (p=0,03) e TMT (p=0,04) no pós-tratamento. Conclusão: A Fisioterapia possui grande valia no tratamento da neuropatia diabética, interferindo sobre as disfunções de sensibilidade e equilíbrio, perpassando pela qualidade de vida. Dessa forma, a utilização de novas técnicas, como o Balance, apresenta boa efetividade e deve ser estimulada, a fim de prevenir complicações inerentes à doença e garantir qualidade de vida aos indivíduos diabéticos. ARTIGO DE Descritores: Diabetes Mellitus; neuropatias diabéticas; reabilitação.Summary Objective: To evaluate sensitivity, balance and quality of life in neuropathic diabetics, comparing the effects of two Physiotherapy protocols. Method: Ten volunteers divided into two groups -Group: Conventional Physical Therapy (GC) and Balance Group (GB), submitted to two different protocols with duration of 1 hour/day, totaling 12 sessions, evaluated in two moments by the instruments: Tandem Testing (TT) and Berg Balance Scale (BSE) for balance; In order to delineate the peripheral sensitivity and the Neuroqol scale, for quality of life (QoL). Statistical analysis was performed using the Student's T and Chi-square tests in the pre and posttreatment (p≤0.05). Results: The GC had a significant post treatment result only in the evaluation of BSE (p = 0.03), while GB presented higher values in the post-treatment period in all the variables evaluated, with quantitative improvements in sensitivity (p = 0 (P = 0.03) and BSE (p = 0.04), in addition to the QOL (p = 0.04). Regarding the comparison between the groups, the significant results were only for BSE variables (p = 0.03) and TMT (p = 0.04) in post treatment. Conclusion: Phy...
