Subacromial impingement syndrome (SAIS) is a painful condition resulting from the entrapment of anatomical structures between the anteroinferior corner of the acromion and the greater tuberosity of the humerus.
The aim of this study was to evaluate the short-term effectiveness of high-intensity laser therapy (HILT) versus ultrasound (US) therapy in the treatment of SAIS.
The study was designed as a randomized clinical trial.
The study was conducted in a university hospital.
Seventy patients with SAIS were randomly assigned to a HILT group or a US therapy group.
Study participants received 10 treatment sessions of HILT or US therapy over a period of 2 consecutive weeks.
Outcome measures were the Constant-Murley Scale (CMS), a visual analog scale (VAS), and the Simple Shoulder Test (SST).
For the 70 study participants (42 women and 28 men; mean [SD] age=54.1 years [9.0]; mean [SD] VAS score at baseline=6.4 [1.7]), there were no between-group differences at baseline in VAS, CMS, and SST scores. At the end of the 2-week intervention, participants in the HILT group showed a significantly greater decrease in pain than participants in the US therapy group. Statistically significant differences in change in pain, articular movement, functionality, and muscle strength (force-generating capacity) (VAS, CMS, and SST scores) were observed after 10 treatment sessions from the baseline for participants in the HILT group compared with participants in the US therapy group. In particular, only the difference in change of VAS score between groups (1.65 points) surpassed the accepted minimal clinically important difference for this tool.
This study was limited by sample size, lack of a control or placebo group, and follow-up period.
Participants diagnosed with SAIS showed greater reduction in pain and improvement in articular movement functionality and muscle strength of the affected shoulder after 10 treatment sessions of HILT than did participants receiving US therapy over a period of 2 consecutive weeks.
肩峰下撞击综合征（SAIS）是一种因肩峰前下角与肱骨大结节之间的解剖结构受卡压而导致疼痛的病症。
本研究旨在评估高强度激光治疗（HILT）与超声（US）治疗在SAIS治疗中的短期疗效。
本研究设计为一项随机临床试验。
研究在一家大学医院进行。
70例SAIS患者被随机分配至HILT组或US治疗组。
研究参与者在连续2周的时间内接受10次HILT或US治疗。
结局指标为Constant-Murley量表（CMS）、视觉模拟量表（VAS）和简易肩部测试（SST）。
对于70例研究参与者（42名女性和28名男性；平均[标准差]年龄 = 54.1岁[9.0]；基线时平均[标准差]VAS评分为6.4[1.7]），VAS、CMS和SST评分在基线时组间无差异。在2周干预结束时，HILT组参与者的疼痛减轻程度明显大于US治疗组参与者。与US治疗组参与者相比，HILT组参与者在接受10次治疗后，从基线开始在疼痛、关节活动、功能和肌肉力量（力产生能力）（VAS、CMS和SST评分）变化方面观察到统计学上的显著差异。特别是，仅组间VAS评分变化差异（1.65分）超过了该工具公认的最小临床重要差异。
本研究受样本量、缺乏对照组或安慰剂组以及随访期的限制。
与连续2周接受US治疗的参与者相比，被诊断为SAIS的参与者在接受10次HILT治疗后，患肩的疼痛减轻、关节活动功能和肌肉力量改善更为明显。
