Analysis of the obstetrician's posture and movements during a simulated forceps delivery.

Background: The objective of this study was to identify and qualify, by means of a three-dimensional kinematic analysis, the postures and movements of obstetricians during a simulated forceps birth, and then to study the association of the obstetricians' experience with the technique adopted.
Method: Fifty-seven volunteer obstetricians, 20 from the Limoges and 37 from the Poitiers University hospitals, were included in this multi-centric study. They were classified into 3 groups: beginners, intermediates, and experts, beginners having performed fewer than 10 forceps deliveries in real conditions, intermediates between 10 and 100, and experts more than 100.
Article Synopsis
- The study investigates the effect of episiotomy suture angles on the risk of obstetric anal sphincter injuries (OASIs) during operative vaginal deliveries (OVDs).
- Out of 2,620 patients, 219 met the criteria for evaluation, and the results showed no significant difference in OASI rates between those with acute (≤45°) and obtuse (>45°) suture angles.
- While higher birth weights and certain delivery methods were linked to increased OASI risk, the findings suggest that a >45° angle episiotomy doesn’t significantly lower OASI risk, although the overall occurrence of OASIs was low in the study group.
Introduction: The number of deliveries by forceps decreases significantly in favour of the vacuum. Now, when the use of forceps is necessary, physicians less experimented with this procedure are likely to induce serious and preventable perineal or foetal injuries. Training therefore becomes essential.

Our secondary objective was to examine the association between the elastic properties of pelvic floor muscles (PFM) and perineal tears at childbirth.
Methods: This was a prospective monocentric study, including nulliparous women.
The H-test is commonly used during return-to-sport decisions after hamstring muscle injury. The primary aim was to evaluate the reliability of two-dimensional (2D) video analysis for the H-Test. The second aim was to assess its validity compared to an electronic gyroscope (gold standard), and the third aim was to establish normative values.
