Learning surgical technical skills.
Training issues raised by the recent introduction of laparoscopic surgical techniques led to this analysis of motor-skill learning principles as they apply specifically to the learning of technical surgical skills. The most accepted theories of motor-skill learning are presented, not as opposing views, but as complementary constructs. The behaviourist school of thought's main contribution is the executive routine or knowledge of the steps of a procedure. Schmidt's schema theory and MacKay's node theory suggest that perceptual information may play an important role in the quality of the performance. The conclusions reached from neuropsychologic testing experiments on surgeons are that visuospatial perceptual skills (the ability to represent mentally the physical environment and the movement to be performed) are the major determinants of surgical technical performance. Learners should make use of learning strategies that improve mental representation of a skill and the corresponding anatomy. Specific strategies discussed include imagery, mental practice and a systematic review of performance that focuses on the perceptual feedback received by the learner.
