To determine the efficacy of a fixed dose of ultrasound energy to treat acute lateral ligament sprains of the ankle joint.
Double-blind randomised controlled trial.
Accident and Emergency department of University Teaching Hospital.
Patients presenting at Accident and Emergency with ankle injuries.
Ultrasound or placebo, and Tubigrip.
Pain measured with visual analogue scales, swelling using a tape measure, range of movement using a fluid-filled goniometer, and weight bearing using two scales simultaneously.
Patients in both groups improved symptomatically. There were no statistically significant differences between groups in any outcome measure. Within groups, statistically significant differences were detected in pain perceived, and range of movement (dorsiflexion).
At the dose and duration used, ultrasound therapy is no better than placebo in the management of lateral ligament injuries.
确定固定剂量的超声能量治疗踝关节急性外侧韧带扭伤的疗效。
双盲随机对照试验。
大学教学医院急诊科。
因踝关节损伤到急诊科就诊的患者。
超声或安慰剂，以及弹力绷带。
采用视觉模拟量表测量疼痛，用卷尺测量肿胀程度，使用充满液体的角度计测量活动范围，同时使用两个秤测量负重情况。
两组患者症状均有改善。在任何观察指标上，两组之间均无统计学显著差异。在组内，在疼痛感知和活动范围（背屈）方面检测到统计学显著差异。
在所使用的剂量和持续时间下，超声治疗在外侧韧带损伤的管理中并不比安慰剂更好。
