BACKGROUND: Resistance exercise is considered first-line management for lateral elbow tendinopathy (LET). TikTok enables sharing of short-form videos with algorithms distributing videos with higher engagement (e.g., views/likes).
PURPOSE: To assess resistance exercise video quality for LET on TikTok between general users and self-identified health care professionals and explore associations between engagement and video quality.
STUDY DESIGN: Social media review using a systematic review framework.
METHODS: TikTok was searched using five hashtags. Included videos were in English and focused on resisted exercise. Creator and video engagement metrics were extracted, with viewing index and engagement rate calculated. The DISCERN and Tennis Elbow Exercise Education Score (TEEES) were used to assess video quality. A Kruskal-Wallis test examined differences between general users and self-identified health care professionals and Spearman's rho (rs) correlations explored associations between video quality and engagement metrics. Median (interquartile range) were reported.
RESULTS: Ninety-eight videos were included with no significant differences in engagement between general users and self-identified health care professionals. Overall, resistance exercise video quality was poor with no significant differences between general users (DISCERN 26 [22-29] out of 75, TEEES 8 [5-10] out of 25) and self-identified health care professionals (DISCERN 25 [21-27], TEEES 7 [5-9]; p = 0.37 and p = 0.35, respectively). Video quality was weakly correlated with video likes, favourites, and viewing index (rs = 0.23, p = 0.03; rs = 0.23, p = 0.02; rs = 0.21, p = 0.04, respectively).
CONCLUSIONS: The quality of resistance-based exercise videos for LET on TikTok was poor, regardless of user profile. While some engagement metrics were associated with video quality, viewers should not rely on these metrics to indicate video quality.
