A Prospective Randomized Study Comparing the Efficacy of Electrotherapy to Ultrasound - Guided Intra-Articular Steroid Injections for Frozen Shoulder.
Article in Journal of orthopaedic case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Frozen shoulder (adhesive capsulitis) is a disabling condition marked by pain and restricted range of motion (ROM). This study compares the effectiveness of electrotherapy (ET) and ultrasound-guided intra-articular steroid injections (UG-IASI), two common non-operative treatments. Materials and Methods: In this prospective, randomized trial, 60 patients with unilateral Frozen shoulder were assigned to either ET (n = 30) or UG-IASI (n = 30). Outcomes were assessed at baseline, 1, 3, and 6 months, and 1 year using the shoulder pain and disability index (SPADI) and ROM measurements. Statistical analyses included mixed-effects models and subgroup analysis for diabetes. Results: UG-IASI resulted in significantly greater SPADI and ROM improvements than ET at 1, 3, and 6 months (P < 0.05). By 1 year, the difference was no longer significant. UG-IASI showed notable gains in abduction and flexion. Diabetic patients experienced reduced improvements across both groups. Conclusion: UG-IASI provides superior early and mid-term outcomes in pain relief and shoulder function compared to ET. While long-term differences narrow, early intervention with UG-IASI supports faster recovery. A tailored approach, considering comorbidities and patient needs, is recommended for optimal care.
