RESUMO
O arco longitudinal medial (ALM) desempenha funções na biomecânica do pé. O estudo teve como objetivo comparar os resultados da avaliação do ALM do complexo articular do tornozelo entre índice do arco plantar (IAP) e índice de Staheli, classificação de Viladot e linha de Feiss. Trata-se de um estudo transversal, onde a amostra experimental foi constituída de sujeitos do sexo feminino com idade entre 13 a 19 anos, praticantes de futebol. As mensurações foram realizadas por meio da plantigrafia, excetuando-sea linha de Feiss. Os testes que mais compatibilizaram foram o IAP e a classificação de Viladot, porém sem significância estatística, considerando o coeficiente de Kappa de 0,32 e 0,30 para os pés direito e esquerdo. Na comparação do IAP, linha de Feiss e índice de Staheli, o coeficiente de Kappa foi de baixa concordância, pois, não pode ser calculado pela ausência de pé plano nos dois últimos testes. Conclui-se que ocorreu incompatibilidade entre os métodos de avaliação.
The longitudinal plantar arch (LPA) perform biomechanics functions in the foot. The aim of this study was to compare the relationship between different index to measure the LPA of the foot. The arc index, Staheli index, Viladot classification and Feiss line were compared. In the transversal study, the experimental samples were soccer players females with age between 13 to 19 years. The measure were performed by plantigraphy, with out Feiss line. Although non significant the higher agreement was reached between the arch index and Staheli index. This comparison presented a Cohen's Kappa coefficient of 0,32 and 0,30 for right and left foot respectively. The comparison between arch index either with Feiss line or Staheli index presented low agreement. In conclusion this study showed low agreement between methods to measure the LPA.

OBJECTIVE: To compare muscle activity and joint moments in the lower extremities during walking between subjects with stroke and control subjects. METHOD: We compared fifteen healthy volunteers and fifteen stroke patients, with the same age gender and weight data had been compared by electromyography. The system of signals acquisition used consisted of five pairs of electrodes of surface, beyond one electrogoniometer on the axis articulate of rotation of the joint of the ankle in study. RESULTS: Onset times with respect to heel-strike for the medial gluteus, tibialis anterior, soleus, rectus femoris and medial hamstring muscles were significantly earlier during the gait cycle in subjects with stroke than in control subjects. The cessation times of soleus, tibialis anterior, rectus femoris, and medial hamstring muscles were significantly prolonged in subjects with stroke. CONCLUSION: Subjects with stroke showed more co-contractions of agonist and antagonist muscles at the ankle and knee joints during stance phase. These gait changes and co-contractions may allow subjects with stroke to adopt a safer, more stable gait pattern to compensate for diminished sensory information from the ankle.
