To investigate the overall effect of repeated ultrasound treatment in carpal tunnel syndrome (CTS).
Patient-blinded, placebo-controlled, before-after treatment trial.
University hospital PM&R department outpatient clinic and neurology department electromyography laboratory.
Eighteen women with diagnosis of CTS in 30 hands.
Three groups, each with 10 cases of CTS, were randomly established. Continuous ultrasound therapy, with intensities of 1.5W/cm2 (group A), 0.8W/cm2 (group B), and 0.0W/cm2 (group C), was applied to palmar carpal tunnel area for 5 minutes, 5 days a week, for 2 weeks.
Patients were evaluated clinically and electrophysiologically before and after the treatment.
At the end of treatment, statistically significant improvement was obtained in clinical parameters in all groups: pain (p < .05), pain/paresthesia at night/day (p < .05), and frequency of awakening at night (p < .05). Although there was no statistically significant before-after difference in electrophysiologic studies, slightly decreased motor nerve conduction velocity and increased motor distal latency were noted in groups A and B, but not in group C.
Ultrasound therapy in CTS was comparable to placebo ultrasound in providing symptomatic relief, and the probability of a negative effect on motor nerve conduction needs to be considered.
探讨重复超声治疗对腕管综合征（CTS）的总体疗效。
患者盲法、安慰剂对照、治疗前后试验。
大学医院物理医学与康复科门诊及神经科肌电图实验室。
18名女性，共30只手被诊断为CTS。
随机分为三组，每组10例CTS患者。对掌侧腕管区域分别施加强度为1.5W/cm2（A组）、0.8W/cm2（B组）和0.0W/cm2（C组）的连续超声治疗，每周5天，每次5分钟，共2周。
治疗前后对患者进行临床和电生理评估。
治疗结束时，所有组的临床参数均有统计学意义的改善：疼痛（p <.05）、夜间/白天疼痛/感觉异常（p <.05）和夜间觉醒频率（p <.05）。虽然电生理研究前后无统计学意义上的差异，但A组和B组的运动神经传导速度略有下降，运动远端潜伏期增加，而C组未出现此情况。
超声治疗CTS在缓解症状方面与安慰剂超声相当，且需要考虑对运动神经传导产生负面影响的可能性。
