Modeling in Therapy

65
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Mixed Reality

Background:

  • Simulation enhances surgical learning curves and efficiency.
  • A lack of dedicated models for skull base surgical approaches exists.
  • This study addresses this gap by developing a novel training system.

Purpose of the Study:

  • To develop a cost-effective mixed reality system for surgical training.
  • To evaluate the system's efficacy in training the retrosigmoid approach.
  • To assess the impact on surgeon performance and confidence.

Main Methods:

  • Developed an ultrarealistic physical model with augmented reality from patient scans.
  • Incorporated features for cost reduction and model reusability.
  • Conducted pre- and post-test assessments with neurosurgical residents and young surgeons in control and test groups.

Main Results:

  • The control group showed a mean score difference of 4.80 (95% CI: 1.08-9.79).
  • The test group demonstrated a mean score difference of 5.43 (95% CI: 1.67-8.20).
  • Self-satisfaction scores averaged 24.0 (23-25), indicating high relevance and confidence.

Conclusions:

  • The ultrarealistic mixed reality model effectively facilitates retromastoid access to the cerebellopontine angle.
  • A trend towards improved performance was observed in the group utilizing the model.
  • Participants found the model highly relevant for neurosurgical training and confidence building.
