RESUMEN
To compare the effects of low level laser therapy (LLLT) and corticosteroid injection in patients with moderate carpal tunnel syndrome (CTS). Eighty-seven patients (143 wrists) with moderate CTS were randomized to the corticosteroid or LLLT groups. 40 mg of triamcinolone acetate solution was applied to carpal tunnel of 44 patients (74 wrist). LLLT was applied to 43 patients (70 wrist) five times a week, for a total of 15 sessions (fluence of 6 j/cm2 for 1 min per point at a wavelength of 830 nm). Outcome measures were numbness and pain, QuickDASH questionnaire, grasping tests, Tinel and Phalen tests, electrophysiological tests and MRI evaluations, which were tested at the baseline and 1st and 6th months after the treatment. Eighty patients (133 wrists) completed the study at the end of 6 months. VAS and Quick DASH scores were better in the corticosteroid group in the 1st month, but there were no significant differences between groups in the 6th month. Phalen and Tinel tests, strength tests, and motor distal latency improved significantly and similarly in both groups at the 1st and 6th months. Sensory distal latency and sensory nerve conduction velocity showed significant improvements in the 1st and 6th months only in the corticosteroid group. In both groups, median nerve intensity rate and palmary spring rate improved significantly after the treatment. Based on this study, corticosteroid injection and LLLT groups showed statistically significant difference at the 1st month (short-term), whereas there was no significant difference at the 6th month (intermediate-term).

The aim of this study was to compare the efficacy of low-level laser treatment (LLLT) and extracorporeal shock wave therapy (ESWT) in the treatment of subacromial impingement syndrome (SIS). Seventy-one patients with subacromial impingement were randomly assigned to LLLT (n = 37) and ESWT (n = 34) groups. The patients received a total of 15 sessions of LLLT or once a week for 3 sessions of ESWT. All patients, before treatment, at the end of treatment, and 3 months after treatment, were evaluated with range of motion (ROM), visual analogue pain scale (VAS pain), Shoulder Pain and Disability Index (SPADI), Beck Depression and Anxiety Inventories, the Short Form Health Survey (SF-36), and Pittsburgh Sleep Quality Index (PSQI). In both groups, there was a significant improvement in all outcome measures (p < 0.05) except the mental health score in the LLLT group. ESWT group showed more improvements in terms of SPADI disability and total scores, PSQI, and physical-mental health scores at the end of treatment (p < 0.05). The improvement in VAS pain day and SPADI scores at the third month was significantly more evident in the ESWT group (p < 0.05). Both LLLT and ESWT treatments are effective in the treatment of SIS in the short-medium term and can be used in clinical practice. Future larger prospective clinical trials are needed to investigate the long-term efficacy and optimal treatment protocol of LLLT and ESWT in SIS.
