摘要： 目的 探讨在拉伸和收缩干预后小腿肌肉状态对踝关节本体感觉的影响。方法 选取健康男性志愿者20名，以右足为参考足，采用对照、拉伸、收缩3种方式干预右小腿肌肉后，通过足匹配试验检测踝关节本体感觉，对不同干预方式与不同目标角度时的左侧踝足匹配角度与双侧踝关节角度绝对匹配误差进行统计分析。结果 左侧踝足匹配角度未出现显著的肌肉状态×目标角度交互作用（P > 0.05）。不同的小腿肌肉状态和目标角度对左侧踝足匹配角度有显著主效应（P < 0.001）。小腿肌肉拉伸状态下的足匹配角度显著低于对照状态和收缩状态的足匹配角度（P < 0.001）。不同目标角度对双侧踝关节角度绝对匹配误差有显著主效应（P < 0.05），不同的小腿肌肉状态对双侧踝关节角度绝对匹配误差无显著主效应（P > 0.05），但小腿肌肉状态×目标角度对双侧踝关节角度绝对匹配误差有显著交互作用（P < 0.05）。结论 在小腿肌肉拉伸状态下踝关节本体感觉显著向跖屈方向偏倚，而小腿肌肉收缩状态对踝关节的本体感觉无显著影响。

Abstract: Objective To investigate calf muscle conditioning in terms of ankle proprioception after stretch and contraction interventions. Methods A total of 20 healthy male volunteers were recruited in this study. The right foot was designated as the reference foot, and ankle proprioception was tested by performing the foot matching task after interventions were carried out on the right calf muscle in three ways, namely, control, stretch, and contraction. After data collection, the left ankle matching angle and average matching error of bilateral ankle joint angles in different interventions and target positions were statistically analyzed. Results Based on the results, no significant interaction was observed between muscle condition and target angle in the left ankle matching angle(P > 0.05). However, the main effects of various calf muscle conditions and target angles on the left ankle matching angle were evident(P < 0.001). The left ankle matching angle of the stretch group was significantly lower compared with that of the control and contraction groups(P < 0.001). In addition, it was noted that the target angle had significant main effects on the average matching error of bilateral ankle joint angles(P < 0.05). In comparison, muscle conditioning showed no significant main effects on the average matching error of bilateral ankle joint angles(P > 0.05). Lastly, significant interactions were observed in the average matching error of bilateral ankle joint angles(P < 0.05). Conclusion Findings of this study suggest that under calf muscle stretch conditioning, ankle proprioception tends to significantly favor plantar flexion. On the contrary, calf muscle contraction conditioning had no significant effects on ankle proprioception.
