Simulation-based Training for Ultrasound-guided Popliteal Sciatic Nerve Block

The goal of this study is to evaluate whether remote asynchronous feedback is non-inferior to direct synchronous feedback during simulation-based training for ultrasound-guided popliteal sciatic nerve block performance. The main questions it aims to answer are: Does asynchronous feedback achieve technical skill acquisition outcomes comparable to direct synchronous feedback? Can asynchronous feedback optimize teaching resources without compromising training quality? Researchers will compare two feedback modalities within a simulation-based training program for deliberate practice of ultrasound-guided popliteal sciatic nerve block techniques. Participants will: Receive training with either direct synchronous feedback or remote asynchronous feedback Perform simulation-based deliberate practice sessions Be assessed using validated instruments for technical skill performance
