Effectiveness of repeated ultrasound-guided suprascapular nerve blocks in hemiplegic shoulder pain: A randomized controlled trial.
Trial report in Medicine, 2026. 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
backgroundHemiplegic shoulder pain (HSP) is a common complication after stroke, significantly impairing rehabilitation. While suprascapular nerve block (SSNB) has shown promise in pain management, its long-term efficacy, especially with repeated applications, remains unclear.
objectiveThis study aimed to evaluate the effectiveness of ultrasound-guided repeated SSNB in reducing pain, improving range of motion (ROM), and enhancing motor function in patients with HSP.
methodsThis double-blind, randomized controlled trial included 42 patients with HSP, allocated to either the SSNB group or the control group in a 1:1 ratio. The SSNB group received ultrasound-guided injections of levobupivacaine and triamcinolone at baseline, 3 weeks, and 6 weeks, while the control group received sham injections. All participants followed a standardized physiotherapy program. Pain was assessed using the visual analog scale, ROM with a goniometer, spasticity with the Ashworth scale, and motor recovery with the Brunnstrom scale. Assessments were conducted at baseline, 1, 4, and 7 weeks.
resultsThirty-nine patients completed the study. The SSNB group showed significant reductions in visual analog scale scores at 1, 4, and 7 weeks compared to the control group (P < .05). ROM for abduction and flexion significantly improved in the SSNB group at 7 weeks (P < .05). However, there were no significant differences between groups in Ashworth or Brunnstrom scores at any time point.
conclusionRepeated SSNB effectively reduces pain and improves ROM in patients with HSP when combined with physiotherapy. However, it does not significantly impact spasticity or motor function. Further research with longer follow-ups and active comparators is needed to determine its long-term benefits.
