The aim of this study was to analyse and compare the effects of gait training on a treadmill associated with partial body weight support (PBWS) or auditory stimulus (AS) and the kinematic variables of gait and quality of life (QOL) in patients with Parkinson's disease (PD). Twenty-one volunteers with PD participated and were divided into: group with PBWS (GPBWS) with AS (GAS), and control group (CG). Soil step length (SL), SL variability (SLV), step width (SW), SW variability (SWV), gait speed (GS), and QOL were evaluated by the Parkinson’s Disease Questionnaire-39 (PDQ-39). The training was performed for six weeks, with three weekly sessions of 30 minutes. The results showed homogeneity of groups (p> 0.05). There was an increase of SW in the GPBWS (p= 0.006) and GS in the GAS (p= 0.048) and decreased PDQ-39 in the CG (p= 0.005) and GAS (p= 0.006). For groups, regardless of evaluation, there were differences in SWV between the GPBWS and GAS (p= 0.030); for evaluations, independently of groups, there were differences in GS (p= 0.048) and PDQ-39 (p= 0.002). It was concluded that, among the studied conditions, there was a significant improvement for the groups: AS in GS and QOL, CG in QOL and GPBWS did not improve. Thus, considering the clinical effect, treadmill training, independently of the stimuli, is clinically advantageous for gait improvements and QOL.

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.
Introduction: Soccer is the most played sport in the world and the one that causes more injuries. Imbalance between knee flexor and extensor is the main cause of muscle injuries in soccer players. Objective: The aim of this study was to verify the asymmetry and the correlation between the strength and flexibility of knee flexor and extensor as well as the difference of these variables between the right and left limbs in youth soccer players. Method: The sample consisted of 45 male youth soccer players for at least a year, aged between 13 and 16 years (14.7+0.86). The athletes underwent an assessment of flexibility of the posterior chain through the sit and reach test on Wells' Bench and an assessment of flexibility of the quadriceps using the Ely's test, with measurement of passive range of motion by goniometry. The peak of muscle strength was measured using a load cell (EMG System, Brazil). Results: Data analysis showed difference between the values obtained in the Ely's test of right and left leg (p=0,03), which did not happen for flexion strength (p=0.45), extension (p=0.41) and H:Q ratio (p = 0.40) when comparing the two members. It was observed a significant negative correlation between the H:Q ratio and the flexibility of the posterior chain test either for the right side (r=-0.40; p=0.006) or left side (r=-0.50; p=0.0004). Also a significant positive correlation was observed between quadriceps strength and flexibility of the posterior chain, both for the right (r=0.31; p=0.03) and the left side (r=0.32; p=0.02). Just for the left side a significant positive correlation was observed when compared the flexor muscle strength with the flexibility of the quadriceps (r=0.30; p=0.03). Conclusion: We conclude from this study that the flexibility of the posterior chain may be related to the strength of the antagonists, however, when the two physical qualities were compared in the same muscles, it showed no correlation.
ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOA esteira ergométrica vem sendo utilizada para análise da marcha em muitos estudos, porém, torna-se necessário verificar se a marcha em esteira pode reproduzir de modo similar a marcha em solo. O objetivo do presente estudo foi comparar as variáveis cinemáticas da marcha em esteira e em solo em pacientes com Doença de Parkinson. A amostra foi constituída por sete indivíduos de ambos os gêneros, com diagnóstico de Parkinsonismo idiopático que realizassem marcha independente. Foi realizada avaliação biomecânica da marcha em solo com velocidade de preferência por cinco vezes consecutivas. Os participantes caminharam em um circuito para garantir uma marcha contínua. A análise da marcha em esteira foi realizada por 30 minutos após protocolo de familiarização. Não foram encontradas diferenças significativas nas variáveis analisadas entre a marcha em solo e em esteira dos participantes. A marcha em solo é semelhante, em relação às variáveis cinemáticas analisadas, à marcha em esteira após período de familiarização. Palavras-chaves: Doença de Parkinson, marcha, solo, esteira ergométrica. ABSTRACTThe treadmill has been used for gait analysis in many studies, however, it is necessary to check whether the treadmill gait can reproduce similarly to gait on soil. The aim of this study was to compare gait kinematic variables on a treadmill and on soil in patients with Parkinson's disease. The sample consisted of seven individuals of both genders, diagnosed with idiopathic Parkinsonism who performed independent walking. Gait biomechanical analysis on soil with preferred speed for five consecutive times was performed. Participants walked on a circuit to ensure continuous walk. Gait analysis on the treadmill was realized for 30 minutes after familiarization protocol. No significant differences were found on the variables between gait on soil and on the treadmill of the participants. The gait in soil is similar, in relation to the kinematic variables analyzed, to the treadmill gait after familiarization period.
