OBJECTIVE: To compare the efficacy of rotator interval (RI) vs posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS). DATA SOURCES: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science, and Cochrane Central, up to January 2023 was conducted. STUDY SELECTION: Randomized controlled trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS. DATA EXTRACTION: The primary outcome was pain, and the secondary outcomes were function, and range of motion (ROM). Two authors independently assessed the risk of bias using the Cochrane risk-of-bias tool version 2. A random-effects model and generic inverse variance method were performed. Effect sizes were estimated using mean difference (MD) and standardized mean difference (SMD). DATA SYNTHESIS: A total of 5 clinical trials involving 323 subjects were included for the meta-analysis. US-guided corticosteroid injections into the RI revealed significant pain relief (MD 1.33 [95% confidence interval (CI) 0.20 to 2.46]; P=.02) and significant functional improvement (SMD 1.31 [95% CI 0.11 to 2.51]; P=.03) compared with the PA after 12 weeks. CONCLUSION: The results suggest the injection of corticosteroid into RI space is more effective than PA after 12 weeks in improving both pain and functional scores in patients with PFS.

STUDY DESIGN: Single arm, quasi-experimental study design. BACKGROUND: To describe the effects of whole-body cryotherapy on pain, disability, and serum inflammatory markers in patients with chronic low back pain. METHODS: A quasi-experimental trial was performed on adult patients between 18 and 65 years with chronic low back pain. After obtaining informed consent, participants underwent 20 sessions of whole-body cryotherapy (at -160 °C) during a 5-week time span. Patient reported pain and disability measures (Pain Numerical Rating Scale [PNRS], Oswestry Disability Index [OSI], and Roland Morris Questionnaire [RMQ]) were obtained at each of the twenty sessions. Blood samples were obtained to analyze serum inflammatory markers at baseline, 10th and 20th session. RESULTS: Forty-one participants were included in the study. A significant decrease was observed between the initial and final PNRS, ODI, and RMQ scores (p < 0.001). A significant reduction in the PNRS was found after 4 sessions of whole-body cryotherapy (p < 0.001). We observed decreasing values of pro-inflammatory serum marker IL-2 (p = 0.046) and a significant increase in the anti-inflammatory serum marker IL-10 (p = 0.003). No adverse events were reported during the study. CONCLUSIONS: Whole-body cryotherapy is an effective therapy for pain and disability treatment in chronic low back pain. It also produces changes in serum markers of inflammation, decreasing pro-inflammatory markers and increasing anti-inflammatory markers.
