Which method does NOT help in assessing the adequacy of uterine contractions?

The method that does not help in assessing the adequacy of uterine contractions is external toco monitoring. This technique involves placing a pressure-sensitive device on the mother's abdomen, which measures the tension of the uterine wall during contractions. While it can detect when contractions occur, it does not provide detailed information about the strength, duration, or effectiveness of the contractions themselves.

In contrast, intrauterine pressure catheter (IUPC) monitoring directly measures the intrauterine pressure, offering precise data about the intensity of contractions. Visual palpation allows healthcare providers to feel the uterine firmness and frequency of contractions, providing practical insights into their adequacy. Additionally, calculating Montevideo Units (MVUs) combines the strength and frequency of contractions to assess overall uterine activity quantitatively, which is vital in evaluating whether contractions are sufficient for labor progression.
