Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the investigators examine the cognitive load (CL) and performance of a laparoscopic procedure in immersive virtual reality and controlled virtual reality in a randomized, controlled setup. Virtual reality (VR) simulators combined with head mounted displays (HMDs) enable highly immersive virtual reality (IVR) for surgical skills training, potentially bridging the gap between the simulation environment and real-life operating room (OR) conditions. However, the increased complexity of the learning situation in IVR could potentially induce high CL thereby inhibiting performance and learning.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

A single-center randomized trial was designed according to the CONSORT statement
Primary Study Purpose

OTHER

Blinding Strategy

NONE

Participants and the principal investigators were blinded to performance metrics by the simulator during the supervised procedure and the three test procedures. Participants and the data collector could not be blinded to the allocation/intervention. The investigator in charge of the statistical analysis was blinded to participants' group allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Immersive virtual reality

Completing the procedures in immersive virtual reality

Group Type OTHER

Immersive virtual reality

Intervention Type OTHER

In the IVR environment, four different 360-degrees videos were in sequence played as backdrop during the procedure. The videos reflected real life situations in the operating room with two videos representing calm periods, one video representing a light stressor and one video representing a severe stressor with a bleeding (2 ml/s) being triggered in the simulation. Participants complete the procedures while wearing the head mounted device.

Conventional virtual reality

Completing the procedures in conventional virtual reality
