Relationship between Range of Motion and Isometric Shoulder Strength in Elite Team Handball Players.
Article in International journal of sports physical therapy, 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: The prevalence of overuse shoulder injuries is unfortunately common in team handball, potentially impacting sport participation and quality of life after players' professional careers. Shoulder rotational strength and glenohumeral range of motion have been proposed to influence the development of shoulder injuries. Purpose: This study aimed to compare external and internal shoulder rotation range of motion and isometric strength among elite male and female handball players with current shoulder pain, previous shoulder pain, and no shoulder pain. Study design: An explorative cross-sectional study. Methods: Maximal isometric shoulder internal and external rotator strength and shoulder internal and external rotation range of motion were measured and compared between sexes and among players with current shoulder pain, previous shoulder pain, and no shoulder pain. All data distributions were tested for normality with the Shapiro-Wilk test, histograms, and qq plots. An ANOVA was used to compare the internal and external shoulder range of motion and strength. Results: A total of 136 elite team handball players, 57 women (1.74±0.06 m, 72.4 ± 8.3 kg, and 22.4±4.9 years) and 79 men (1.89±0.08 m, 90.8 ± 11.8 kg, and 22.3 ± 5.2 years) participated. A significant difference in maximal internal (p<0.001) and external (p=0.004) shoulder rotator strength was found between sexes, with no significant difference in range of motion. When categorized by groups, male athletes in the no-pain group had greater internal rotator strength than males in the current and previous pain groups (p<0.042). Furthermore, female athletes in the no-pain group showed significantly less internal and external rotation range of motion compared to those playing with shoulder pain and those with previous pain. Conclusion: Greater maximal isometric shoulder strength was found for men than women, primarily of the internal rotators, among all three groups. However, the men in the no-pain group had greater strength of the internal rotators than the two other groups. Range of motion was comparable between sexes, but the women without shoulder pain demonstrated significantly less internal and external rotation range of motion compared to those playing with shoulder pain and those with previous pain. Level of evidence: 3.
