Supraspinatus tendinopathy is one of the most common causes of shoulder pain. Many studies support conservative treatments such as exercise, trigger point dry needling or corticosteroid injections. Otherwise, a minimally invasive approach with percutaneous electrolysis (PE) has also been used successfully in shoulder pain, although evidence about its long-term effects is scarce. The aim of this trial was to determine the effects of PE on supraspinatus tendinopathy compared with trigger point dry needling (TDN). Thirty-six patients with supraspinatus tendinopathy were randomly assigned to either a PE group ( = 18) or a TDN group ( = 18). Both groups also performed eccentric exercises. The main outcome to be measured was the Numerical Pain Rating Scale (NPRS), but the shoulder range of motion (ROM) and trigger point pressure pain threshold (PPT) were also considered. A one-year follow-up was conducted. Significant differences favoring the PE group were found regarding pain at one-year follow-up ( = 0.002). The improvement achieved in the PE group was greater in the NPRS ( < 0.001), proximal PPT, middle PPT, distal PPT (all < 0.001) and ranges of movement. PE seems to be more effective than TDN in relieving pain and improving ROM and PPT supraspinatus values in patients with supraspinatus tendinopathy, both right after treatment and at one-year follow-up.
冈上肌腱病是肩部疼痛最常见的病因之一。许多研究支持运动、触发点干针疗法或皮质类固醇注射等保守治疗方法。此外，经皮电刺激（PE）这种微创方法也已成功用于治疗肩部疼痛，不过关于其长期效果的证据较少。本试验的目的是确定与触发点干针疗法（TDN）相比，PE对冈上肌腱病的疗效。36例冈上肌腱病患者被随机分为PE组（n = 18）或TDN组（n = 18）。两组患者均进行离心运动。主要测量指标是数字疼痛评分量表（NPRS），同时也考虑肩部活动范围（ROM）和触发点压痛阈值（PPT）。进行了为期一年的随访。在一年随访时发现，PE组在疼痛方面有显著优势（P = 0.002）。PE组在NPRS（P < 0.001）、近端PPT、中间PPT、远端PPT（均P < 0.001）以及活动范围方面的改善更大。在治疗后及一年随访时，PE在缓解冈上肌腱病患者的疼痛、改善ROM和冈上肌PPT值方面似乎比TDN更有效。
