Using Motion Tracking to Analyze Forceps Paths During Simulated Forceps-Assisted Vaginal Deliveries.

Area of Science:

• Medical simulation
• Surgical training
• Obstetrics and Gynecology

Background:

• Forceps-assisted vaginal delivery is a critical obstetric skill.
• Objective assessment of surgical technique is essential for training.
• Variability in provider experience may impact delivery outcomes.

Purpose of the Study:

• To evaluate motion tracking's ability to distinguish differences in forceps paths.
• To compare forceps technique between experienced and inexperienced obstetric providers during simulated deliveries.

Main Methods:

• Pilot study with 24 residents and 6 faculty using high-fidelity models.
• Motion tracking software analyzed forceps shank paths.
• Key metrics included path length, displacement, and final angle.

Main Results:

• Significant differences found in total path length and y-plane displacement between groups.
• Faculty demonstrated distinct paths compared to postgraduate year 1 and 2 residents.
• No significant differences observed in x-plane displacement or final angle.

Conclusions:

• Motion tracking can objectively identify skill variations in forceps-assisted vaginal delivery.
• This technology offers potential for developing targeted educational interventions for residents.
• Improving forceps technique through objective feedback can enhance obstetric care.
