Tridandani found in pregnant women that though the superficial reflexes, with the exception of the abdominal, were diminished, the deep and tendon reflexes were markedly increased, especially that of the knee, these changes being more marked in primiparæ than in multiparæ, and more pronounced as pregnancy advanced, the normal condition returning with ten days after labor.
