title: Bilateral inversion-eversion range of motion comparisons among college athletes.
abstract: The purpose of this study was to compare bilateral passive inversion-eversion ROM values in the ankles of individuals with no prior history of ankle trauma. Thirty-seven intercollegiate athletes, 25 males and 12 females, participated in this study. Passive inversion-eversion ROM was measured on an ankle stability test instrument, with the ankle positioned at 0 degrees plantarflexion. The ANOVA results demonstrated a significant bilateral difference in inversion ROM at the 0.01 level of confidence and a significant left/right eversion difference at the 0.05 confidence level. These results suggest that many of the assessment procedures utilized by physical therapists in the treatment of ankle ligamentous injuries may be inaccurate, if their validity is dependent upon contralateral comparisons. Factors related to limb dominance and athletic participation may have influenced the findings in this study. J Orthop Sports Phys Ther 1990;11(11):543-546.
