Summary
Trunk muscle endurance training improved laparoscopic task performance by reducing discomfort and errors. This training enhances postural control, benefiting surgeons in simulated laparoscopy.
Area of Science:
- Surgical Education
- Biomechanics
- Exercise Physiology
Background:
- Laparoscopic surgery demands sustained postural control.
- Fatigue in trunk muscles can negatively impact surgical performance and lead to errors.
- Objective assessment of fatigue and its impact on novice laparoscopic skills is crucial.
Purpose of the Study:
- To determine the effect of trunk muscle endurance training on perceived back postural fatigue.
- To evaluate the impact of this training on simulated laparoscopic task performance.
Main Methods:
- Thirty-one novice medical students were randomized into a training or control group.
- The training group completed a 6-week trunk endurance program.
- Laparoscopic task performance was assessed under postural fatigue before and after the intervention.
Main Results:
- The training group demonstrated significant improvements in trunk endurance (P<0.05).
- This led to reduced perceptions of discomfort (P<0.001) and fewer laparoscopic task errors (P<0.02).
- The control group showed no significant changes.
Conclusions:
- Enhanced trunk muscle endurance positively influences the perception of postural fatigue.
- Improved trunk endurance correlates with better laparoscopic task performance and reduced errors.
- Trunk endurance training may be a valuable strategy for managing surgical errors in laparoscopy.
