These were previously referred to as "deep tendon reflexes" and are usually examined with the use of a reflex hammer. Kayring1. ment of respirations, deep tendon reflexes, and urine out-put is adequate to monitor for maternal toxicity without the need to determine the actual maternal serum magne-sium levels" (p. 174). Each tendon reflex is subserved by specific spinal cord segments: Reflex. The diagnosis requires that the patient have: Elevated blood pressure (systolic 140 or diastolic 90 mm Hg, the latter measured using the fifth Korotkoff sound) Previously normal blood pressures Hyperreflexia is generally caused by an overreaction of the involuntary nervous system to stimulation. 0-4: Deep tendon reflexes, of which the knee-jerk is the best known, are spinal reflexes triggered by hitting certain tendons. In normotensive pregnant women the patellar reflex was cross-sectionally recorded using SEMG at four time points during the following gestational age periods: 12-14 weeks, 26-28 weeks, 32-34 weeks, 36-40 gestational weeks and 6-8 weeks postpartum. .
