Myofascial Pain Syndrome causes disability in daily life activities and despite all efforts, it continues to be a challenge, perpetuating suffering, overloading services and costs. New treatment options need to be tested.
We aimed to quantify the rESWT short-term analgesic effect and identify the predictors of success through comparing results achieved in MPS and Articular Pain (AP).
Retrospective cohort study of 1,580 patients with Myofascial Pain Syndrome or Articular Pain underwent two weekly radial Extracorporeal Shock-wave Therapy sessions. The pain intensity was measured by Visual Analog Scale before and one week after the end of the treatment (3 weeks).
The therapy decreases pain by 62.50% (p< 0.0001), with a high success rate (91.59%) and a low worsening of baseline conditions rate (2.1%). The best recommendation is for patients with intense myofascial pain (Visual Analog Scale ⩾ 70 mm), using high shock-wave frequency (⩾ 15 Hz).
Two rESWT sessions promote pain relief, with a high success rate and low rates of treatment abandonment and worsening. The best results are obtained in myofascial pain patients with high pain intensity, treated with high-frequency dosage.
肌筋膜疼痛综合征导致日常生活活动障碍，尽管付出了一切努力，它仍然是一个挑战，使痛苦持续存在，使服务和成本负担过重。需要测试新的治疗选择。
我们旨在通过比较肌筋膜疼痛综合征和关节痛（AP）的结果来量化 rESWT 的短期镇痛效果，并确定成功的预测因素。
对 1580 名肌筋膜疼痛综合征或关节痛患者进行回顾性队列研究，每周接受两次径向体外冲击波治疗。治疗结束后一周（3 周）前后通过视觉模拟量表测量疼痛强度。
该治疗可使疼痛减轻 62.50%（p<0.0001），成功率高（91.59%），基础条件恶化率低（2.1%）。对于疼痛强度高（视觉模拟量表 ⩾70mm）的肌筋膜疼痛患者，建议使用高冲击波频率（⩾15Hz）。
两次 rESWT 治疗可缓解疼痛，成功率高，治疗中断和恶化率低。在高疼痛强度、高频剂量治疗的肌筋膜疼痛患者中获得最佳效果。
