本研究旨在评估健康年轻男性和女性在自行选择的速度和步频下步态期间胫骨前肌和腓肠肌外侧肌共同收缩活动的可能差异。统计步态分析方法，允许步态的统计特征的平均空间-时间和表面肌电为基础的参数超过数百步步行试验，应用于30个年龄匹配的主题：15名男性和15名女性。共同收缩被评估为肌肉活动之间的重叠时期。结果显示，两组在步态周期中均出现四种不同的共同收缩。两组之间的激活时刻（开-关）没有检测到显着差异，否则，与男性相比，女性的所有共同收缩都发生在更高的步幅次数（%）中：早期站立（40.7 +/- 18.7% vs. 18.9 +/-11.0%，p
The study aimed to assess possible differences between healthy, young males and females in co-contraction activity of tibialis anterior and gastrocnemius lateralis during gait at self-selected speed and cadence. The Statistical-Gait-Analysis methodology, allowing a statistical characterization of gait by averaging spatial-temporal and sEMG-based parameters over hundreds of strides per walking trial, was applied on thirty age-matched subjects: 15 males and 15 females. Co-contractions were assessed as the overlapping periods between muscular activities. Results showed the occurrence of four different co-contractions during gait cycle, for both groups. No significant differences in activation instants (ON-OFF) were detected between groups, Otherwise, all the co-contractions occurred in higher number of strides (%) in females, respect to males: in early stance (40.7 +/- 18.7% vs. 18.9 +/- 11.0%, p
