To determine if peroneus longus (PL), peroneus brevis (PB), medial gastrocnemius (MG) and tibialis anterior (TA) muscle activation patterns during inversion perturbation and running tasks are suppressed following lidocaine injection to the anterior talofibular (ATF) and calcaneofibular (CF) ligament regions.
Fourteen recreationally active male subjects (age, 24.8 ± 2.9 years; height, 177.0 ± 6.0 cm; mass, 77.7 ± 6.7 kg) participated. Testing was performed under five injection conditions to the ATF and CF regions: 1 ml saline, 1 ml lidocaine, 3 ml saline, 3 ml lidocaine or no injection. Following injection condition, traditional ankle taping was applied. Electromyography patterns of the PL, PB, MG and TA were collected while subjects performed continuous lateral jumps on a custom-built device which elicited an ankle inversion perturbation and treadmill running (3.35 m s(-1), 0.5 % incline).
No significant differences were demonstrated in muscle activation patterns of the PL (n.s.), PB (n.s.), MG (n.s.) or TA (n.s.) for any variable across injected conditions during both tasks. Statistical power was 0.214-0.526 for the PL, 0.087-0.638 for the PB, 0.115-0.560 for the MG and 0.118-0.410 for the TA.
Injection of lidocaine up to 3 ml to the ATF and CF regions did not suppress muscle activity of the PL, PB, MG or TA during the inversion perturbation or running tasks. Injection up to 3 ml of 1 % lidocaine to the ATF and CF regions may be used without sacrificing the muscle activation patterns about the ankle. This finding is clinically relevant since the use of the injection does not put the patient at any higher risk of reinjury to the site.
确定在距腓前韧带（ATF）和跟腓韧带（CF）区域注射利多卡因后，在进行内翻干扰和跑步任务时，是否会抑制腓骨长肌（PL）、腓骨短肌（PB）、内侧腓肠肌（MG）和胫骨前肌（TA）的肌肉激活模式。
14 名有休闲运动习惯的男性受试者（年龄 24.8 ± 2.9 岁；身高 177.0 ± 6.0 cm；体重 77.7 ± 6.7 kg）参与了这项研究。在 ATF 和 CF 区域接受以下 5 种注射条件：1 ml 生理盐水、1 ml 利多卡因、3 ml 生理盐水、3 ml 利多卡因或不注射。注射后，对踝关节进行传统的胶带包扎。当受试者在一个定制的设备上进行连续的侧向跳跃时，收集 PL、PB、MG 和 TA 的肌电图模式，该设备会引起踝关节内翻干扰和跑步机跑步（3.35 m/s，0.5%坡度）。
在任何注射条件下，在两种任务中，PL（n.s.）、PB（n.s.）、MG（n.s.）或 TA（n.s.）的肌肉激活模式均无显著差异。PL 的统计功效为 0.214-0.526，PB 为 0.087-0.638，MG 为 0.115-0.560，TA 为 0.118-0.410。
在 ATF 和 CF 区域注射高达 3 ml 的利多卡因不会抑制内翻干扰或跑步任务中 PL、PB、MG 或 TA 的肌肉活动。在 ATF 和 CF 区域注射高达 3 ml 的 1%利多卡因可能不会影响踝关节周围的肌肉激活模式，且不会增加对该部位的再损伤风险。这一发现具有临床意义，因为这种注射不会使患者面临更高的再受伤风险。
