Summary
A new system, EvalLap EMG-ACC, objectively measures muscle activity during laparoscopy. Expert surgeons exhibit less muscle activity than novices, indicating skill development.
Area of Science:
- Surgical Simulation
- Biomedical Engineering
- Motor Control
Background:
- Laparoscopic surgery requires specialized skills.
- Objective assessment of surgical skill is crucial for training.
- Current assessment methods may lack objective physiological data.
Purpose of the Study:
- Introduce EvalLap EMG-ACC, a novel physical laparoscopy simulator.
- Quantify muscle activity using electromyography (EMG) and accelerometry.
- Objectively evaluate laparoscopic skills based on muscle activity and experience levels.
Main Methods:
- 14 participants (6 experts, 8 students) performed tasks on a laparoscopic box trainer.
- EMG and ACC signals recorded from upper extremity muscles using wireless sensors.
- Seven evaluation metrics compared between novice and expert surgeons.
Main Results:
- Proximal and distal arm muscles (trapezius, deltoids, biceps, forearms) showed significant activity.
- Laparoscopic experience correlated with differences in EMG amplitude, muscle activity, hand acceleration, user movement, and fatigue.
- Deltoid, bicep, forearm EMG amplitude, and user movement differed significantly between experience groups.
Conclusions:
- Muscle activation patterns during laparoscopy vary with surgical experience.
- Expert surgeons demonstrate reduced muscle activity compared to novices.
- EvalLap EMG-ACC shows potential for differentiating surgical skill levels in basic cutting tasks.
