Evidence that focally cooling the ankle joint facilitates soleus and peroneus longus spinal reflex activity in healthy subjects has been reported. This response has been confirmed in individuals with a history of joint pathology for the soleus but not in the peroneus longus and tibialis anterior. The purpose of this study was to identify the effects of ankle cooling on isokinetic eversion and inversion torque and in peroneus longus, tibialis anterior H-reflex (H(max):M(max)) in subjects with functional ankle instability (FAI). Twenty-four college aged subjects volunteered for this study. Peroneus longus and tibialis anterior H(max):M(max), and concentric eversion and inversion torque were recorded prior to and following each session. This protocol was used to compare FAI to healthy ankle group. There were no significant differences between groups. There were weak and no significant relationships between the corresponding muscles motoneuron excitability and their peak torque measurements. Ice application to the joint did not alter the peroneus longus or the tibialis anterior.
有证据表明，局部冷却踝关节可促进健康受试者的比目鱼肌和腓骨长肌的脊髓反射活动。这种反应在有跗关节病史的个体中得到了证实，但在腓骨长肌和胫骨前肌中没有得到证实。本研究的目的是确定踝关节冷却对功能性踝关节不稳定（FAI）患者的等速外翻和内翻扭矩以及腓骨长肌、胫骨前肌 H 反射（H(max):M(max)) 的影响。24 名大学生自愿参加了这项研究。在每次测试前后，记录腓骨长肌和胫骨前肌 H(max):M(max)以及离心外翻和内翻扭矩。该方案用于将 FAI 与健康踝关节组进行比较。组间无显著差异。相应肌肉运动神经元兴奋性与其峰值扭矩测量值之间存在弱相关且无统计学意义。关节冰敷并未改变腓骨长肌或胫骨前肌。
