Chronic Achilles tendinopathy is a painful condition and there are often unsatisfactory results with conservative treatment. Extracorporal shock-wave therapy (ESWT) has been introduced for the management of various soft tissue conditions. The objective of the study was to compare the effect of supplementing conservative treatment of chronic Achilles tendinopathy with ESWT or placebo.
This was a randomized, double-blind, placebo-controlled trial. Patients assigned to nonoperative treatment of chronic achilles tendinopathy were randomized to receive either active ESWT or sham ESWT over 4 weeks. There were 48 patients (28 men) with a mean age of 47 (19-80) years. American Orthopaedic Foot and Ankle Society (AOFAS) score and pain were assessed before treatment, during the 4-week treatment period, and at 4, 8, and 12 weeks of follow-up.
Both groups improved during the treatment and follow-up period. The mean AOFAS score increased from 74 (SD 12) to 81 (16) in the placebo group and from 70 (6.8) to 88 (10) in the intervention group (p = 0.05). Better results were seen in the intervention group at 8 and 12 weeks of follow-up (p = 0.01 and p = 0.04, respectively). Interpretation Extracorporal shock-wave therapy appears to be a supplement for the treatment of chronic Achilles tendinopathy.
慢性跟腱病是一种疼痛性疾病，保守治疗效果往往不尽人意。体外冲击波疗法（ESWT）已被用于治疗各种软组织疾病。本研究的目的是比较用ESWT或安慰剂辅助治疗慢性跟腱病的效果。
这是一项随机、双盲、安慰剂对照试验。被分配接受慢性跟腱病非手术治疗的患者被随机分为两组，在4周内分别接受主动ESWT或假ESWT治疗。共有48例患者（28例男性），平均年龄47岁（19 - 80岁）。在治疗前、4周治疗期间以及随访的4周、8周和12周时评估美国矫形足踝协会（AOFAS）评分和疼痛情况。
两组在治疗和随访期间均有改善。安慰剂组的平均AOFAS评分从74（标准差12）增至81（16），干预组从70（6.8）增至88（10）（p = 0.05）。在随访的8周和12周时，干预组的效果更好（分别为p = 0.01和p = 0.04）。解读：体外冲击波疗法似乎是治疗慢性跟腱病的一种辅助手段。
