Assessment of Fetal Knee Angular Velocity as a Possible Method to Determine the Effect of Prenatal Exposure to Cocaine

Measurement of fetal join angular velocity may be beneficial in assessing the effect on the fetus of maternal use of drugs. The effect of maternal cocaine and other drug use on the fetus is not well defined. The ability to measure the effect of maternal drug use on the fetus in a safe, accurate, and reliable way is challenging. A method of measuring fetal knee joint angular velocity is described. Clinical implications for use of the method are discussed.
