Effectiveness of high-voltage radiofrequency on suprascapular nerve for the treatment of chronic shoulder pain.

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: Chronic omalgia, which often results from a rotator cuff injury, is a common musculoskeletal condition. The literature supports the effectiveness of 45V pulsed radiofrequency for treating painful shoulders, as well as the effectiveness of high-voltage for certain painful conditions. Objective: Our main aim was to conduct a study investigating the use of 100V high-voltage pulsed radiofrequency in patients with chronic omalgia. Methods: We conducted a pre-post quasi-experimental study including 31 patients with chronic omalgia due to a muscle-tendon injury that did not respond to pharmacological treatment. Patients had to be over 18 years old, understand the invasive technique, and have previously experienced an effective suprascapular nerve block. During the initial consultation, we assessed pain levels using the Visual Analogue Scale (VAS) and the Shoulder Pain and Disability Index (SPADI). We then administered radiofrequency at 42° and 100V for 360s. Patients were re-evaluated using the VAS and SPADI scales at two, four, and six months. Results: The mean VAS score at the initial visit was 9.16 (95% CI: 8.90-9.42) out of 10 points. At two months, the mean score was 3.4 (1.15-5.65, 95% CI); at four months, it was 4.6 (2.54-6.66, 95% CI). At six months, the mean VAS score was 5.21 (4.40-6.02; 95% CI). The observed differences were statistically significant (p < 0.05). An initial assessment was performed using the SPADI scale, yielding a total pre-intervention score of 82.6%. Subsequently, at the six-month follow-up, the total SPADI score was 47%. The difference in the total SPADI score (pain and disability) was also statistically significant (p < 0.05). Conclusion: High-voltage pulsed radiofrequency (100V) applied to the suprascapular nerve is an innovative treatment that offers very promising results for treating chronic shoulder pain.
