Area of Science:

  • Medical Education
  • Surgical Training
  • Biomechanics

Background:

  • Motion analysis provides objective data for surgical skill assessment.
  • Evaluating hand movements is key to improving surgical technique and precision.
  • Accelerometer-based sensors offer a novel method for quantifying surgical performance.

Purpose of the Study:

  • To analyze hand motions during endoscopic sinus surgery training using accelerometer sensors.
  • To quantify motion characteristics differentiating surgical expertise levels.
  • To enhance objectivity and effectiveness of surgical training feedback.

Main Methods:

  • 24 participants (senior, specialist, resident) performed procedures on sheep heads.
  • Bluetooth Accelerometer WitMotion sensors tracked hand movements.
  • Procedural time, path length, and acceleration were analyzed using statistical tests (Shapiro-Wilk, Kruskal-Wallis).

Main Results:

  • Significant differences (p<0.001) in procedural time, acceleration, and path length were found across experience groups.
  • Senior surgeons exhibited shorter procedural times and less hand movement compared to specialists and residents.
  • Distinct differences in hand motion patterns were observed between dominant and non-dominant hands.

Conclusions:

  • A clear learning curve exists in endoscopic sinus surgery, from resident to senior levels.
  • Surgical residents demonstrate less efficiency (more time, greater motion) than experienced surgeons.
  • Findings support tailoring surgical training programs to enhance efficiency and economy of motion.
