Effects of upper and lower limb preference on torque production in the knee flexors and extensors.

The purpose of this study was to examine the phenomena of foot preference and its relationship to hand preference and torque production in the knee flexors and extensors. Fifty-four college aged students participated in the study. Each subject's hand and foot preference was determined. Torque production in the knee flexors and extensors was evaluated isokinetically at three speeds. Chi-square analysis revealed a very weak relationship between foot preference and hand preference. Paired t-tests demonstrated no significant differences in torque production when the preferred leg was tested against the nonpreferred leg or when the left leg was compared to the right. The authors conclude that there was a tendency for the subjects to prefer their right leg. However, one cannot predict foot preference from hand preference. Implications for future research and practice were presented. J Orthop Sports Phys Ther 1989;11(5):202-207.
