abstract
PURPOSE: Examination of the hip provides information regarding risk for pre-arthritic hip disorders, knee injuries, and low back pain. The purpose of this study was to report a hip screening examination of asymptomatic female soccer athletes and to test the hypothesis that these findings vary by competition experience. METHODS: Asymptomatic females from a youth soccer club, a college, and a professional team were evaluated. Passive hip range of motion, hip abduction strength, and hip provocative tests were assessed. Data were compared for the grade/middle school, high school, college, and professional athletes. RESULTS: One hundred and seventy-two athletes with a mean age of 16.7 ± 5 years (range 10-30) participated. Professional athletes had less flexion (HF) for both hips (p < 0.0001) and less internal rotation (IR) for the preferred kicking leg (p < 0.05) compared to all other groups. Grade/middle school athletes had more external rotation in both hips as compared to all other groups (p < 0.0001). For the preferred kicking leg, collegiate athletes had less hip abduction strength as compared to other groups (p < 0.01). Positive provocative hip tests were found in 22 % of all players and 36 % of the professionals. In professionals, a positive provocative test was associated with ipsilateral decreased HF (p = 0.04). CONCLUSION: Asymptomatic elite female soccer athletes with the most competition experience had less bilateral hip flexion and preferred kicking leg IR than less-experienced athletes. Positive provocative hip tests were found in 22 % of athletes. Future studies are needed to show whether these findings link to risk for intra-articular hip or lumbar spine and knee disorders. LEVEL OF EVIDENCE: III.
