Abstract:

Introduction: Research on healthy pregnant women's reflexes is almost unheard of, even if an estimation of reflexes is a conventional part of the physical examination of preeclamptic patients, and hyperreflexia is generally considered to be a warning sign of eclampsia. The aim of the present study was to investigate the possible impact of gestation on tendon reflexes and the Babinski response, as examined in a clinical bed-side manner. Material and Methods: A prospective, single-blind, cross-sectional study. Three study groups comprised non-pregnant (n = 20), 14–18 weeks (n = 16), and 34–38 weeks (n = 15) healthy pregnant women respectively. Two experienced neurologists examined separately each participant's patellar reflexes, Achilles reflexes, and Babinski response and rated them on two different scales, National Institute of Neurological Disorders and Stroke (NINDS) scale and Mayo Clinic Scale for Tendon Reflex Assessment. Inter-observer estimations between the patient groups and the neurologists were made by mixed effect model methodology. Results: The patellar and Achilles reflexes´ strengths were rated similarly in all three groups (p > 0.05). The inter-observer difference was non-significant between the neurologists´ estimations (p > 0.05). The neurologists estimated the Babinski response in a few cases as neutral (0), otherwise down (normal). Conclusions: The patellar and Achilles reflex strengths are not affected in uncomplicated pregnancy. There is good concordance between neurologists´ estimations of tendon reflex strengths rated on the NINDS and Mayo scales.
