Medical Advisability of Youth Pitching Recommendations on the Internet

BACKGROUND: As the incidence of youth pitching injuries and surgical procedures attributed to overuse has drastically increased, there are quality concerns about popular internet resources regarding arm care for youth pitchers. PURPOSE/HYPOTHESIS: To assess the medical advisability of online arm care recommendations for youth pitchers. It was hypothesized that websites contain misleading arm-care information that is discordant with medical advice. STUDY DESIGN: Cross-sectional study. METHODS: We reviewed the first 100 websites populated after a Google search for youth pitching recommendations. Websites were categorized by type (athletic organization, commercial, or educational) and content quality (medically advisable, discordant, or neutral), the latter with respect to the Pitch Smart guidelines used by Major League Baseball. Chi-square tests of independence and z tests of independent proportions were used to compare column proportions among categories of website content quality for each type of website source. Given the small sample sizes in some instances, the Fisher-Freeman-Halton exact test was performed to assess the relationship between website source type and quality of information. RESULTS: Of the 99 qualifying websites, 76 were categorized as medically advisable, 16 as discordant, and 7 as neutral. In addition, 92% of educational websites and 94.7% of athletic organization websites featured exclusively advisable content, whereas only 54.8% of commercial websites were advisable. Of the 16 discordant websites, 15 were commercial sites. Educational websites were significantly more advisable and neutral in content when compared with discordant information, while commercial websites were significantly predictive of discordant content. Among the first 50 websites populated according to Google, 42 (84%) were advisable, 6 (12%) discordant, and 2 (4%) neutral. The remaining websites (n = 49) featured 34 (69.4%) that were advisable, 10 (20.4%) discordant, and 5 (10.2%) neutral. CONCLUSION: Study findings indicated that websites of an educational nature are predictive of medically advisable content, while commercial websites (eg, blogs) are associated with discordant information. The abundance and availability of inaccurate internet information should be appreciated by medical professionals and parents/coaches of youth baseball players.
