Effectiveness of neuromuscular stretching with symmetrical biphasic electric currents in the cavus foot.

Background: Pes cavus is a structural deformity in which the increased plantar arch can lead to greater metatarsal verticality with the consequent excess of pressure under the forefoot zone (especially the metatarsal zone), causing pain and significant loss of functional capacity. We sought to determine whether neuromuscular stretching with symmetrical rectangular biphasic currents can reduce the pressure supported by this zone.

Methods: This prospective, nonrandomized, longitudinal, analytical, and experimental controlled trial included 34 patients with pes cavus.
