OBJECTIVE: To investigate the effectiveness of thermal and sub-thermal capacitive-resistive monopolar radiofrequency at 448 kHz plus exercising compared to sham radiofrequency plus exercising on pain, functionality, and quality of life in patients with subacromial pain. DESIGN: Randomized, controlled, parallel, double-blind, three-arm clinical trial. SETTING: Hospital and Primary Care. SUBJECTS: Eighty-one participants with subacromial pain in three intervention groups. INTERVENTIONS: Three interventions with capacitive-resistive radiofrequency (thermal, sub-thermal, and sham) over 9 sessions (3 per week) plus an exercising protocol identical for all groups over 15 sessions (5 per week). OUTCOME MEASURES: Visual analogue scale and pressure pain threshold for pain, Shoulder Pain and Disability Index and Quick-Disabilities of the Arm, Shoulder and Hand for functionality, and quality of life via the European Quality of Life-Five Dimensions were assessed at baseline, immediately posttreatment, and 1 month and 3 months post-intervention. RESULTS: No between-group differences were found in the pain visual analogue scale (F = 1.0; = 0.37), Shoulder Pain and Disability Index (F = 1.0; = 0.36), European Quality of Life-Five Dimensions (F = 0.76; = 0.47), and pressure pain (F = 0.14; = 0.86) outcomes, with a statistical power < 0.30 for all comparisons. Between-group differences were found in the Quick-Disabilities of the Arm, Shoulder and Hand (F = 3.4; < 0.038), with an improvement of -14.1 points (confidence interval at 95% (95% CI) -28.1 to -0.1) in the thermal versus the sham group at 1 month follow-up. The mobility dimension of European Quality of Life-Five Dimensions improved in a greater proportion of participants in the thermal group (22.2% thermal, 7.4% sub-thermal, and 0.0% sham; = 0.02). CONCLUSION: Adding thermal radiofrequency to exercising can further improve slightly functionality and mobility in people with subacromial pain in the short term, but not pain perception. Future studies with larger sample sizes are warranted to increase statistical power.
目的：探究与假射频相比，448kHz 热和亚热电容电阻单极射频联合运动疗法对肩峰下疼痛患者的疼痛、功能和生活质量的疗效。 设计：随机、对照、平行、双盲、三臂临床试验。 设置：医院和初级保健。 受试者：三组干预组中各有 81 名肩峰下疼痛患者。 干预措施：三组接受电容电阻射频（热、亚热和假）治疗共 9 次（每周 3 次），所有组均接受相同的运动方案治疗共 15 次（每周 5 次）。 结局测量：治疗前、治疗即刻、治疗后 1 个月和 3 个月时采用视觉模拟评分法和压力痛阈评估疼痛，采用肩痛和残疾指数以及手臂、肩和手快速残疾评定量表评估功能，采用欧洲生活质量五维度量表评估生活质量。 结果：三组间疼痛视觉模拟评分（F=1.0； =0.37）、肩痛和残疾指数（F=1.0； =0.36）、欧洲生活质量五维度量表（F=0.76； =0.47）和压力痛阈（F=0.14； =0.86）差异均无统计学意义，所有比较的统计效能均<0.30。三组间手臂、肩和手快速残疾评定量表（F=3.4； <0.038）差异有统计学意义，治疗 1 个月随访时，热组与假组相比，改善程度为-14.1 分（95%置信区间（95%CI）为-28.1 至-0.1）。热组中欧洲生活质量五维度量表的活动维度改善的参与者比例更高（热组 22.2%、亚热组 7.4%、假组 0.0%； =0.02）。 结论：在运动治疗的基础上增加热射频治疗，可在短期内略微改善肩峰下疼痛患者的功能和活动能力，但不能改善疼痛感知。需要更大样本量的进一步研究来提高统计效能。
