The objective of this study is to measure elements of quantitative sensory testing including temperature pain threshold, temperature pain tolerance, and thermal and mechanical temporal summation for patients with opioid use disorder on medication-assisted treatment (MAT), and compare these results to gestational age matched controlled pregnant patients not on MAT.
The hypothesis is that women requiring maintenance opioids during pregnancy will have a significant difference in pain sensitivity in the third trimester and immediately postpartum as compared to women who did not require maintenance opioids during pregnancy.
