Assessing the Quality of Consumer Health Information Within the Realm of Shoulder Injuries on TikTok.
Article in Orthopaedic journal of sports 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
Background: Shoulder pain and injury are among the most prevalent musculoskeletal presentations in primary care. With the rise of consumer health information on TikTok, it is pivotal to assess and determine whether the information produced by content creators can serve as a supplement for shoulder rehabilitation and injury prevention. Hypothesis: It was hypothesized that content creators with professional degrees and extensive knowledge within the realm of shoulder injuries would yield valuable and accurate health information. Study Design: Cross-sectional study. Methods: On June 18, 2025, #ShoulderInjury was used as the search item under the TikTok search engine. A total of 9286 videos appeared after the initial search. The authors applied an inclusion criteria of at least 100 likes. Exclusion criteria removed irrelevant, non-English, and duplicate videos, resulting in 209 eligible videos for further analysis. These were evaluated using the DISCERN questionnaire, an instrument used to assess consumer health information on a 1 to 5 scale. Two independent raters scored the videos, and interrater reliability was calculated using weighted Cohen kappa. Results: The 209 analyzed videos garnered 1,408,268 likes and 12,536 comments, with a mean DISCERN score of 2.61. Physicians' videos (n = 41) had the highest mean score (3.52), significantly outperforming nonprofessionals (2.18), physical therapists (2.87), and other professionals (2.79) in critical DISCERN areas ( Conclusion: This study highlights the potential of TikTok as an effective educational tool when used by qualified professionals. Professionally produced content consistently scored higher on the DISCERN scale. Although the findings are promising, it is important to note limitations, like potential biases in DISCERN scoring due to nonblinded raters, the influence of TikTok's algorithm, and the exclusion of videos with <100 likes. Future research should explore social media's role in medical education and assess how to optimize content delivery and engagement.
