Treatment of myofascial trigger points of the infraspinatus is effective in relieving shoulder pain and improving shoulder functions: A randomized clinical trial [post]

2020 unpublished
This study aimed to investigate the effects of ischemic compression treatment (ICT) and low-level laser therapy (LLLT) applied on the trigger points of the infraspinatus muscle on shoulder pain and function in patients with shoulder pain. Methods Thirty patients with shoulder pain were randomly categorized into the ICT group (n = 15) and LLLT groups (n = 15). ICT was performed on three myofascial trigger points (MTrPs) of the infraspinatus muscle twice a week for 4 weeks (eight sessions), with

Shoulder pain was assessed using the visual analogue scale (VAS) and pain pressure threshold (PPT), and shoulder function was assessed using the Korean Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, rotator cuff strength, and range of motion (ROM) of shoulder flexion and abduction. Results Significant changes in VAS score and PPT were found after the intervention in both groups (p < 0.05). Significant changes were observed in the Korean DASH score, rotator cuff strength, and ROM of shoulder flexion (p < 0.05) but not in the ROM of shoulder abduction (p < 0.05). There were no significant differences between the two groups. Conclusion This study showed that both ICT and LLLT applied on the MTrPs of the infraspinatus muscle were effective for relieving shoulder pain and improving shoulder functions in patients with shoulder pain.
