Efeito agudo da marcha em esteira com estímulo auditivo sobre parâmetros cinemáticos da marcha e mobilidade em Parkinsonianos

Abstract

ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOO objetivo do presente estudo foi verificar o efeito agudo da marcha em esteira com estímulo auditivo sobre parâmetros cinemáticos da marcha e mobilidade em Parkinsonianos. Participaram 14 indivíduos com Parkinsonismo idiopático, os quais foram divididos em 2 grupos: grupo intervenção e grupo controle. Foi realizada avaliação, composta por dois testes que avaliam a mobilidade funcional, nomeados Short Physical Performance Battery (SPPB) e Timed up and go (TUG); avaliação da velocidade de marcha através do teste de 10 metros e análise do comprimento de passo em um circuito de 16 metros, em seguida os participantes foram submetidos a uma sessão de marcha em esteira, sendo o grupo intervenção com auxílio de estímulos sonoros e o grupo controle sem estímulos. Ao final da intervenção os indivíduos foram reavaliados. Os resultados mostraram que ambos os grupos apresentaram melhora da mobilidade no teste TUG (p=0.003), da velocidade de marcha no teste de 10 metros (p=0.004) e do comprimento de passo (p=0.029), porém não houve diferença estatística entre os grupos. O SPPB não apresentou diferença significativa após o protocolo de marcha (p=0.118). Conclui-se que uma sessão de marcha em esteira foi efetiva na melhoria dos parâmetros cinemáticos da marcha e mobilidade em estudo, porém a associação do estímulo auditivo não influenciou as variáveis analisadas.Palavras-chave: doença de Parkinson, marcha, esteira ergométrica, estímulo auditivo ABSTRACT The aim of this study was to investigate the acute effect of treadmill training with auditory stimulation on gait kinematic parameters and mobility in Parkinsonians. Participants were 14 individuals with idiopathic Parkinsonism, which were divided into 2 groups: intervention and control group. All patients were assessed through two tests that assess functional mobility, named Short Physical Performance Battery (SPPB) and Timed up and go (TUG); gait speed evaluation by the 10 meters test; and analysis of the step length on a 16-meter circuit, then participants were subjected to a treadmill gait session, intervention group with sound stimuli support and control group without stimuli. At the end of the intervention subjects were reassessed. The results showed that both groups improved mobility in the TUG test (p=0.003), gait speed in the 10 meters test (p=0.004) and step length (p=0.029), but there was no statistical difference between groups. The SPPB did not change significantly after the gait protocol (p=0.118). It is concluded that one treadmill gait session was effective in improving the gait kinematic parameters and mobility study, but the combination of auditory stimuli did not significantly changed the analyzed variables.

Acute effect of partial body weight suspension on the level of cocontraction and gait biomechanics in women with knee osteoarthritis

“…Studies show that gait training with SPPC can effectively modify the gait pattern of various populations, including neurological and orthopedic patients. However, most studies observe 20-30 minutes of walking on the treadmill, per session [16,24]. In the present study, the volunteers walked for three minutes for each proposed condition, which may have been insufficient to modify the biomechanical gait pattern, with no significant differences for the electromyographic and kinematic variables.…”

“…This mechanism induces an increase in the step length because, while the lower limb is brought back, the hip flexors are stretched, activating the muscle spindles, and consequently maximizing this muscle group performance and contributing to a more regular gait pattern. [16].…”

“…For the collection of kinematic data, two Sony ® cameras were used, positioned 1.5 m lateral and posterior to the treadmill and with a sampling frequency of 60 Hz, and photoreflexive markers were fixed at the following anatomical points: the lateral malleolus, the base of the second toe of both feet, and the calcaneus [16].…”

“…The step length was determined as the distance between the marker placed on the second toe and heel, and the step width calculated by the distance between the markers placed on the heel [16].…”
