美国矫形足踝协会建议，在考虑对痛跟综合征进行手术干预之前，至少要进行6个月的非手术治疗。跟腱拉伸运动一直被报道为治疗痛跟综合征的更有效的非手术方式之一。然而，练习的最佳持续时间和频率尚未报道。本研究的目的是评估和比较持续和间歇性跟腱拉伸对缓解与疼痛足跟综合征相关的疼痛的有效性。这项前瞻性、随机、盲法研究于1997年5月至2000年7月进行。共有94人（122个患足）符合纳入标准，并初步同意参加治疗研究组。为了达到我们的目的，研究参与者被随机分为两个拉伸组。一组进行持续的跟腱拉伸（3分钟，每天3次），另一组进行间歇拉伸（5组，每次20秒，每天2次）。在诊断后的四个月里，参与者每月接受一次评估。在每个月的访问中，参与者完成关于他们疼痛的主观问卷。此外，一位物理治疗师测量了每位参与者的跟腱柔韧性。该研究确定，持续和间歇的跟腱拉伸运动都能增加跟腱的柔韧性。灵活性的增加与疼痛的减轻有关。持续拉伸组和间歇拉伸组的结果没有显著差异。数据表明，持续和间歇的跟腱拉伸运动都是治疗足跟疼痛综合征的有效非手术治疗方法。
The American Orthopaedic Foot and Ankle Society recommends at least six months of nonsurgical treatment before considering surgical intervention for painful heel syndrome. Achilles tendon stretching exercises are consistently reported to be one of the more effective nonsurgical modalities for treatment of painful heel syndrome. However, the optimal duration and frequency of the exercises has not been reported. The purpose of this study was to evaluate and compare the effectiveness of sustained and intermittent Achilles tendon stretching for the relief of pain associated with painful heel syndrome. This prospective, randomized, blinded study was performed from May 1997 to July 2000. A total of 94 people (122 affected feet) fit the inclusion criterion and agreed initially to participate in a treatment study group. To achieve our purpose, study participants were randomized into two stretching groups. One group performed sustained Achilles tendon stretches (three minutes, three times daily), the other performed intermittent stretches (five sets, 20 seconds each, two times daily). Participants were evaluated once a month for a period of four months subsequent to diagnosis. At each monthly visit, participants completed subjective questionnaires about their pain. Also, a physical therapist measured each participant's Achilles tendon flexibility. The study determined that both sustained and intermittent Achilles tendon stretching exercises increase Achilles tendon flexibility. This increase in flexibility correlated with a decrease in pain. There was no significant difference in outcome between the sustained and intermittent stretching groups. The data suggest that both sustained and intermittent Achilles tendon stretching exercises were effective nonsurgical treatments for painful heel syndrome.
