Area of Science:

  • Surgical Education
  • Medical Simulation
  • Cognitive Training

Background:

  • Mental practice (MP) shows potential for refining surgical skills but is cognitively demanding.
  • The efficacy of MP may depend on an individual's ability to form mental images.

Purpose of the Study:

  • To investigate if interactive 3D visual aids enhance surgical skill performance during mental practice.
  • To compare the effectiveness of 3D-assisted MP with MP alone and a control group.

Main Methods:

  • 20 surgical trainees were assigned to three groups: 3D-MP (n=5), MP-Only (n=5), or a control group (n=10).
  • Intervention groups underwent 25-minute MP sessions, with one group using interactive 3D visual aids.
  • A control group watched a didactic video; all participants performed a simulated Laparoscopic Cholecystectomy (LC).

Main Results:

  • The 3D-MP group completed the procedure faster than the control group (p=.002).
  • The 3D-MP group made fewer movements (p=.001) and traveled shorter distances (p=.004) compared to controls.
  • No significant differences in safety metrics were observed across groups.

Conclusions:

  • Mental practice (MP) can improve surgical performance.
  • Interactive 3D visual aids may further enhance surgical skills beyond MP alone.
  • Findings support future randomized controlled trials on 3D-assisted MP for surgical preparation.
