Wrist extension strength changes after extensor carpi radialis brevis release in the lateral epicondylitis.

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
purposeLateral epicondylitis (LE) is often attributed to degenerative changes and microscopic ruptures in the extensor carpi radialis brevis (ECRB). Surgical procedures, such as arthroscopic or open ECRB release, are commonly used to address this condition. However, there is limited research on changes in wrist muscle strength and their clinical impact after ECRB release. This study aims to investigate the changes in wrist extension strength following ECRB release in patients with lateral epicondylitis.
methodsA retrospective study was conducted involving thirty-six right-handed patients who underwent open ECRB release at a single institution. Wrist extension strength was measured using a Biodex system during both the initial and two-year follow-up clinical visits. Additionally, clinical outcomes were assessed using the Disabilities of the Arm, Shoulder, and Hand (DASH) score, pain visual analog scale (pain VAS), grip strength, and wrist extension strength. Correlations among these factors were analyzed to explore potential associations.
resultsSignificant improvements were observed in all clinical outcomes, including grip strength and wrist extension strength, following ECRB release. However, at the two-year follow-up, a statistically significant decrease in wrist extension strength was noted compared to the unaffected arm. Despite this decrease, there were no adverse effects on the clinical outcomes (DASH, pain VAS) or grip strength.
conclusionOur study demonstrated a decrease in wrist extension power following ECRB release, which did not significantly impact clinical outcomes. Therefore, we recommend that clinicians inform patients about the potential reduction in wrist extension strength and incorporate wrist extension strengthening exercises into postoperative rehabilitation protocols to facilitate recovery to normal levels. LEVEL OF EVIDENCE: III.
