Nerve conduction studies of lower extremities in pes planus subjects.

ABSTRACT

Pes planus is a condition in which the medial longitudinal arch is depressed. Pedoscop, eyeball visualization, ink mat and roentgenography were used in clinical evaluation. We performed nerve conduction studies on both feet of 28 pes planus subjects. Our results demonstrated mild prolongation distal latency of the medial and lateral plantar sensory nerves, and delayed sensory conduction velocity of the medial plantar sensory nerve. The presence of electrodiagnostic abnormalities in this study population helps to substantiate the presence of compression neuropathy of the medial or lateral plantar nerve in pes planus subjects.
