Comparing the effects of physical practice and mental imagery rehearsal on learning basic surgical skills by medical students.
OBJECTIVE
The purpose of this study was to test the effects of varying the amount of physical practice and mental imagery rehearsal on learning basic surgical procedures.


METHODS
Using a sample of 65 second-year medical students, 3 randomized groups received either: (1) 3 sessions of physical practice on suturing a pig's foot; (2) 2 sessions of physical practice and 1 session of mental imagery rehearsal; or (3) 1 session of physical practice and 2 sessions of imagery rehearsal. All participants then performed a surgery on a live rabbit in the operating theater of a veterinary college under approved conditions. Analysis of variance was applied to pre- and post-treatment ratings of surgical performance.


RESULTS
Physical practice followed by mental imagery rehearsal was statistically equal to additional physical practice.


CONCLUSIONS
Initial physical practice followed by mental imagery rehearsal may be a cost-effective method of training medical students in learning basic surgical skills.
