Effects of acute fatigue of the tibialis anterior due to a weight-bearing muscle activity on the ankle joint position sense in healthy subjects

ABSTRACT

Background: Joint position sense [JPS] is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. If the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in JPS. The aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior [ankle dorsiflexor] could alter the ankle JPS
