Background: Participation in sports place specific demands on the musculoskeletal system that, over time, may cause modifications in soft-tissue. These modifications may result in alterations in range of motion that ultimately may compromise performance and/or contribute to injury. Although there is evidence in the literature regarding side-to-side joint range of motion differences in overhead athletes, it is unknown if a similar modification occurs in the lower extremity. Purpose: Examine bilateral, passive hip rotation range of motion in LPGA golfers. Methods: 31 right-handed LPGA Tour golfers (mean age 32 6.8 yrs, ht. 167.6 6.9 cm, wt. 65.4 9.4 kg) had passive hip rotation (ROM) measured prone using a goniometer. Results: Eight golfers had a side-to-side difference of five degrees or more for internal rotation range of motion. Ten golfers had a side-to-side difference of more than five degrees for external rotation range of motion. Conclusion: Almost one-third of the LPGA golfers had asymmetrical external rotation hip rotation range of motion. Additionally, one-fourth of them had asymmetrical internal rotation range of motion. As previous studies have established, a correlation between hip rotation range of motion asymmetry and low back pain, these findings may have considerable clinical relevance. These results suggest that professional golfers complaining of low back pain need to have an evaluation of their hip rotation range of motion, and employ appropriate interventions to restore and maintain symmetrical ROM.
