Epidemiology of strain/sprain injuries among cheerleaders in the United States

Abstract

Objective The aim of this study is to describe the epidemiology of cheerleading-related strain/sprain injuries by type of cheerleading team and type of event. Methods Athlete exposure (AE) and injury data were collected from 412 United States cheerleading teams via the Cheerleading Reporting Information Online surveillance tool, and injury rates were calculated. Results Strains/Sprains were the most common injury (53%; 0.5 injuries per 1000 AEs) sustained by cheerleaders during our 1-year study. The lower extremities (42%), particularly the ankles (28%), were injured most often. Most injuries occurred during practice (82%); however, the rate of injury was higher during competition (0.8 injuries per 1000 AEs; 95% confidence interval [CI], 0.6-1.0) than during practice (0.6 injuries per 1000 AEs; 95% CI, 0.5-0.6) for all team types. Injuries were sustained most frequently by high school cheerleaders (51%), although college cheerleaders had the highest injury rate (1.2 injuries per 1000 AEs). Strains/Sprains occurred most frequently while attempting a stunt (34%) or while tumbling (32%). Spotting/Basing other cheerleaders (19%) was the most common mechanism of injury and was more likely to result in a lower back strain/sprain than other mechanisms of injury (odds ratio, 3.38; 95% CI, 1.41-8.09; P < .01). Conclusions Cheerleaders should increase their focus on conditioning and strength-building training, which may help to prevent strain/sprain injuries. Spotters and bases should additionally focus on proper lifting technique to help avoid back injury. Guidelines may need to be developed for return-to-play after cheerleading-related strain/sprain injuries.
