Effectiveness of ultrasonography-guided pericapsular nerve group block in patients with adhesive capsulitis resistant to conservative treatment: A prospective observational study.

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
This prospective observational study aimed to evaluate the effectiveness of ultrasonography-guided pericapsular nerve group block (PENG-b) in shoulder pain, function, and kinesiophobia in patients with adhesive capsulitis (AC) resistant to conservative treatment. Sixty-one patients diagnosed with resistant AC were included in this study. Thirty-one patients received PENG-b followed by mobilization (Group 1), while 30 received only mobilization therapy (Group 2). All patients underwent mobilization therapy thrice a week for 6 weeks, targeting ≥80% shoulder range of motion (ROM). Pain was assessed using the Visual Analog Scale, function using the Disabilities of the Arm, Shoulder, and Hand questionnaire and Modified Constant-Murley Score, ROM via goniometry, and kinesiophobia using the Tampa Scale. Group 1 reached the targeted ROM in 10.3 ± 1.6 sessions (range 6-12), whereas all patients in Group 2 required 18 sessions (P < .001). Both groups showed significant posttreatment improvements in Visual Analog Scale, ROM, Modified Constant-Murley Score, Disabilities of the Arm, Shoulder and Hand, and kinesiophobia scores (P < .001). However, Group 1 demonstrated significantly superior outcomes across all measures compared to Group 2 (P < .001). Pain relief was also observed within 24 hours after injection in Group 1. PENG-b provided rapid pain relief and enhanced the effectiveness of subsequent mobilization therapy, resulting in better functional recovery and reduced kinesiophobia within a shorter timeframe. These findings suggest that PENG-b is a safe and effective pre-rehabilitation intervention for patients with AC who are unresponsive to conventional treatments.
