“…46 In another study, there were no numerical values of temperature response reported, but the authors stated that there was no significant change in maternal temperature in response to acute vigorous exercise in the second and third trimesters (online supplementary table 1). 48 Results from three other studies showed that compared with rest, maternal temperature after exercise of any intensity did not increase core body temperature by more than 0.5°C37 39 or 1°C49 (online supplementary table 1). At both points of measurement (first and third trimesters), maternal core temperature did not exceed our thresholds for hyperthermia 49.…”

ObjectiveTo investigate the relationships between exercise and incidence of congenital anomalies and hyperthermia.DesignSystematic review with random-effects meta-analysis .Data sourcesOnline databases were searched from inception up to 6 January 2017.Study eligibility criteriaStudies of all designs were eligible (except case studies and reviews) if they were published in English, Spanish or French, and contained information on population (pregnant women without contraindication to exercise), intervention (subjective or objective measures of frequency, intensity, duration, volume or type of exercise, alone [“exercise-only”] or in combination with other intervention components [e.g., dietary; “exercise + co-intervention”]), comparator (no exercise or different frequency, intensity, duration, volume or type of exercise) and outcome (maternal temperature and fetal anomalies).ResultsThis systematic review and meta-analysis included ‘very low’ quality evidence from 14 studies (n=78 735) reporting on prenatal exercise and the odds of congenital anomalies, and ‘very low’ to ‘low’ quality evidence from 15 studies (n=447) reporting on maternal temperature response to prenatal exercise. Prenatal exercise did not increase the odds of congenital anomalies (OR 1.23, 95% CI 0.77 to 1.95, I2=0%). A small but significant increase in maternal temperature was observed from pre-exercise to both during and immediately after exercise (during: 0.26°C, 95% CI 0.12 to 0.40, I2=70%; following: 0.24°C, 95% CI 0.17 to 0.31, I2=47%).Summary/ConclusionsThese data suggest that moderate-to-vigorous prenatal exercise does not induce hyperthermia or increase the odds of congenital anomalies. However, exercise responses were investigated in most studies after 12 weeks’ gestation when the risk of de novo congenital anomalies is negligible.

BackgroundMaternal counting of fetal movement is a popular and valuable screening tool of fetal wellbeing, however it is still not known what percentage of healthy pregnant women who gave birth to healthy term newborns had experienced decreased fetal movements during gestation and what maternal and fetal factors are associated with this maternal perception of decreased fetal movements. The aim of this study was to assess the associations between maternal perception of decreased fetal movements and maternal and fetal factors in normotensive singleton pregnancies with good pregnancy outcome.MethodsThis study was conducted on 729 normotensive singleton pregnant women who had referred for prenatal visit and on follow up gave birth to healthy term newborns. A questionnaire was completed for the participants and ultrasound imaging was performed. Participants were asked to count their fetal movements for one hour/3times/day. Participants were followed till delivery to exclude mothers with preterm and/or small for gestational age delivery from the study.ResultsPerception of decreased fetal movement was independently associated with maternal employment (Odds Ratio (OR), 2.66; 95% Confidence Interval (95% CI), 1.35–5.23), not having daily exercise (OR, 4.38; 95% CI, 1.56-8.08) and maternal supine position (OR, 3.85; 95% CI, 1.71–8.83).Conclusions8.1% of healthy pregnant women who have good pregnancy outcome report perception of decreased fetal movement when asked to count their fetal movement in third gestational trimester which is independently associated with maternal employment, supine position on counting and not having daily exercise.

“…However, level of maternal physical activity does not correlate with increased fetal movement and may even result in decreased fetal movement and breathing activity. 36 Finally, decreasing the time spent in fixed position with early orthopedic rehabilitation may improve long-term outcomes. Orthopedics should be involved and physical therapy initiated as soon as possible to improve range of motion.…”

After completing this CME activity, physicians should be better able to define arthrogryposis and identify a classification framework to approach prenatal diagnosis, develop a differential diagnosis for a fetus who demonstrates arthrogryposis, formulate an action plan for prenatal diagnosis and assess the importance of a multidisciplinary approach to counseling and care when a fetus is identified to have arthrogryposis.
