Purpose <p>To explore the effects of plantar–sensory stimulation on dynamic postural control, confirm body loadings, and determine whether plantar–sensory stimulation can alter sensory strategies and sensory reweighting in individuals with chronic ankle instability (CAI).</p> Methods <p>Thirty individuals with unilateral CAI were recruited and underwent plantar–sensory stimulation at 100%, 110% and 120% body weight loadings for 10&#xa0;min. Plantar light-touch thresholds were assessed using the Semmes–Weinstein Monofilament. Four postural assessments including motor control test, adaptation test, limit of stability test and sensory organization test were conducted using the NeuroCom Balance Manager System to evaluate postural stability and sensory reweighting before and after treatments.</p> Results <p>There was no significant difference in plantar light-touch thresholds before and after stimulation (<i>p</i> &gt; 0.05). However, postural stability significantly improved in adaptation and sensory organization tests (<i>p</i> &lt; 0.05), and vestibular ratio increased following stimulation (<i>p</i> &lt; 0.05). At baseline, a moderate negative correlation was observed between the light-touch threshold at the big toe and the toes-up sway energy in the adaptation test (<i>p</i> = 0.03). After stimulation, several moderate correlations were found between thresholds at various test sites and adaptation, sensory organization, and motor control tests (<i>p</i> &lt; 0.05).</p> Conclusion <p>Ten-minute plantar–sensory stimulation may enhance reactive postural control and facilitate both inter-sensory (increased vestibular use) and intra-sensory (improved weights of ankle proprioception and plantar sensation) reweighting in individuals with CAI.</p>
