About this trial
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

Treatments tested in this trial
Asynchronous distance feedback
Other interventionThe experimental group practiced with ASYNC. Residents sched- uled their sessions and attended the simulation laboratory alone. The resident logged in to the C1DO1 platform. In the platform, the second 4 stages were practical exercises. The student recorded himself, performing the observed technique.9 The instructor was not present and provided feedback asynchronously via a C1DO1 platform. The ASYNC included texts, audio recordings, drawings annotating the trainee's video, and short example error videos from a library. In addition to the specific feedback in response to residents' videos, instructors also provided an objective assessment based on scores using a 9-item global rating scale (GRS). The student reviewed their feedback in the platform and identified the skills to improve for the next session.
Synchronous direct feedback
Other interventionThe control group practiced with SYNC. The SYNC group attended the simulation laboratory for practice sessions. Residents were scheduled to practice with the instructor in a one-to-one ses- sion. The instructor was present during all the sessions and gave instructions and feedback in real time throughout all sessions (traditional face-to-face feedback modality).

Trial outcomes
Primary outcomes
Performance assessment
The PRE and POST assessments were videotaped for evaluation by 2 independent and blinded reviewers. The simulation center staff recorded the assessment videos for a standard vision of the participant's hands and the ultrasound image. Two reviewers rated each resident's performance using an specific GRS previously validated. The reviewers were different from the instructors.
Secondary outcomes
ICSAD measurement
Two sensors of a tracking motion device were attached to the operator's hands, during the assess- ment. The Imperial College Surgical Assessment Device (ICSAD) is a device that tracks hand motion during a procedure using sensors placed on the back of the operator's hands. In this study, the ICSAD device recorded the total distance traveled by both hands (TPL). The simulation center staff installed the device in the operators' hands and recorded the data.
