A reliable, low-cost screening tool to identify high-risk cephalopelvic disproportion (CPD) patients is of paramount importance especially in resource-limited areas where a timely referral to a medical facility for assisted delivery or cesarean section would make the difference between saving the life of mother and child and potential loss of both patients. To address this pressing need we propose to develop and test a simple, ultra-low cost portable technology using off-the-shelf Microsoft Kinect sensor to quantify an obstructive score to identify women at high risk for CPD.
