Abstract
Context: Valid and reliable measurements of ankle-complex motion have been reported using the Hollis Ankle Arthrometer. No published normative data of ankle-complex motion obtained from ankle arthrometry are available for use as a reference for clinical decision making. Objective: To describe the distribution variables of anklecomplex motion in uninjured ankles and to establish normative reference values for use in research and to assist in clinical decision making. Design: Descriptive laboratory study. Setting: University research laboratory. Patients or Other Participants: Both ankles of 50 men and 50 women (age = 21.78 +/- 2.0 years [range, 19–25 years]) were tested. Intervention(s): Each ankle underwent anteroposterior (AP) and inversion-eversion (I-E) loading using an ankle arthrometer. Main Outcome Measure(s): Recorded anterior, posterior, and total AP displacement (millimeters) at 125 N and inversion, eversion, and total I-E rotation (degrees) at 4 Nm. Results: Women had greater ankle-complex motion for all variables except for posterior displacement. Total AP displacement of the ankle complex was 18.79 +/- 4.1 mm for women and 16.70 +/- 4.8 mm for men (U= 3742.5, P<.01). Total I-E rotation of the ankle complex was 42.1° +/- 9.0° for women and 34.13° +/- 10.1° for men (U = 2807, P <.001). All variables were normally distributed except for anterior displacement, inversion rotation, eversion rotation, and total I-E rotation in the women’s ankles and eversion rotation in the men’s ankles; these variables were skewed positively. Conclusions: Our study increases the available database on ankle-complex motion, and it forms the basis of norm-referenced clinical comparisons and the basis on which quantitative definitions of ankle pathologic conditions can be developed.
