Abstract

Achilles reflex speed was determined by measuring the valley-peak (V-P) interval in 152 pregnant and 90 nonpregnant women. In pregnant patients, mean reflex speed was slightly slower, a difference which was highly significant statistically. When 42 gravidas were studied again six weeks’ postpartum and mean reflex speed compared to that during pregnancy, again a statistically significant slowing of reflex speed was found to exist during pregnancy. Since this test has been used as an adjunct in diagnosing thyroid abnormalities, the change produced by pregnancy alone should be recognized. The relation to known changes in circulating thyroid hormone concentration and thyroid activity during pregnancy arc discussed. A normal range of values for serum PBI during pregnancy is suggested.
