Abstract

Yoga foot drop is a kind of drop foot, a gait abnormality. It is caused by a prolonged sitting on heels, a common yoga position of vajrasana. The name was suggested by Joseph Chusid, MD, in 1971, who reported a case of foot drop in a student who complained about increasing difficulty to walk, run, or climb stairs. The cause was thought to be injury to the common peroneal nerve, which is compressed and thereby deprived of blood flow while kneeling.

Yoga foot drop is a potential adverse effect of yoga, allegedly unmentioned by yoga teachers and books.
