Reliability of Inversion and Eversion Peak- and Average-Torque Measurements from the Biodex System 3 Dynamometer

Thomas W. Kaminski and Geoff C. Dover

Objective:

To determine the reliability of inversion and eversion concentric isokinetic-strength measurements from the Biodex System 3 isokinetic dynamometer.

Setting:

University biomechanics research laboratory.

Subjects:

Thirty-five volunteers free from any lower leg and ankle injuries within the preceding year.

Measurements:

Peak (PT) and average (AT) isokinetic torque at 30°/s and 120°/s for subtalar-joint inversion and eversion.

Results:

PT intraclass correlation coefficients (ICC2,1) ranged from .54 to .92. AT ICC2,1 ranged from .55 to .91. These ICCs were good to excellent for both PT and AT at each speed and motion tested, except for fair ICCs produced from right-foot-eversion measurements at 30°/s.

Conclusions:

Inversion and eversion subtalar-joint strength measurements from the Biodex System 3 isokinetic dynamometer are reliable.

athletic circles, only 2 studies to our knowledge have examined the effects of these exercises on IFM function. 16 , 20 Because little is known regarding the effects of toe-posture exercises as a modality in the treatment of the ankle–foot complex or for fitness, it is important that these interventions

Ankle proprioception provides essential information to enable adjustment of ankle positions, and ankle plays a major role in the maintenance and correction of postural control in different directions during both
