Hyperpronation is a risk factor associated with medial tibial stress syndrome, patellar femoral pain syndrome, and ACL injuries. Previous research with site-specific electrical stimulation to the plantar sole has shown significant alterations in activity of muscles associated with those sites. The purpose of this study was to examine the effects of sensory-level electrical stimulation to the medial longitudinal arch on foot contact pressure-time-integral (PTI) and contact area associated with hyperpronation during two barefoot conditions, one electrode pad only and one electrical stimulation condition. No significant differences were found between conditions for midfoot and rearfoot PTI. Midfoot contact area was greater for electrode pad only and electrical stimulation than both barefoot conditions, which is likely due to the thickness of the pads attached to the plantar surface touching down before the sole would without them. No significant difference was found between electrode pad only and electrical stimulation.
