Persistent muscle inhibition of the fibularis longus and soleus muscles and altered joint arthrokinematics may play a role in chronic ankle instability (CAI). Joint mobilization has been shown to improve ankle joint motion, but effects on surrounding musculature is unknown. The purpose of this study was to determine the change in fibularis longus and soleus activation following tibiofibular joint manipulation in individuals with CAI. Forty-three subjects were randomized to one of three groups (proximal tibiofibular manipulation, distal tibiofibular manipulation, or control). A two-way mixed model ANOVA was used to compare changes in the ratio of the maximum H-reflex and maximum M-wave measurements (H/M ratio) of the fibularis longus and soleus between groups over time (pre, post 0, 10, 20, 30 min). The distal tibiofibular joint manipulation group demonstrated a significant increase (P<.05) in soleus H/M ratio at all post-intervention time periods except 20 min post-intervention (P=.48). The proximal tibiofibular joint manipulation and control groups did not demonstrate a change in soleus H/M ratios. All groups demonstrated a decrease (P<.05) from baseline values in fibularis longus (10-30 min post-intervention) and soleus (30 min post-intervention) H/M ratios. Interventions directed at the distal tibiofibular joint acutely increase soleus muscle activation.
腓骨长肌和比目鱼肌持续的肌肉抑制以及关节运动学的改变可能在慢性踝关节不稳定（CAI）中起作用。关节松动术已被证明可以改善踝关节运动，但对周围肌肉的影响尚不清楚。本研究的目的是确定 CAI 患者胫骨腓骨关节操作后腓骨长肌和比目鱼肌激活的变化。43 名受试者随机分为三组（胫骨腓骨近端操作、胫骨腓骨远端操作或对照组）。使用双向混合模型 ANOVA 比较各组之间腓骨长肌和比目鱼肌最大 H 反射和最大 M 波测量值（H/M 比）在时间上（干预前、干预后 0、10、20、30 分钟）的变化。除干预后 20 分钟（P=.48）外，胫骨腓骨远端关节操作组在所有干预后时间点的比目鱼肌 H/M 比均显示出显著增加（P<.05）。胫骨腓骨近端关节操作组和对照组的比目鱼肌 H/M 比没有变化。所有组在干预后 10-30 分钟（干预后）和比目鱼肌（干预后 30 分钟）的腓骨长肌和比目鱼肌 H/M 比均显示出降低（P<.05）。针对胫骨腓骨远端关节的干预措施可急性增加比目鱼肌的肌肉激活。
