Brief Summary
The goal of this study is to 1) identify motion capture variables that can be used to differentiate surgical experience level and 2) evaluate if these variables can be used in a surgical education setting to improve resident performance.

Outcome Measures
Primary Outcomes (7)
Completion time
Time to complete each task measured in seconds
1 year
Instrument pathlength
Pathlength of surgical instrument tip measured in cm
1 year
Motion smoothness
Motion smoothness of surgical instrument tip measured by the number of changes in acceleration (m/s\^2)
1 year
Instrument orientation
Orientation of surgical instrument tip measured in the three planes of motion (depth, pitch, roll, yaw), quantified in degrees relative to the surgical trainer box's local coordinate system.
1 year
Fundamentals of Laparoscopy Skill (FLS) score
\- A numbered score is calculated following procedures outlined in the Fundamentals of Laparoscopy Skills (FLS) modules
1 year
Objective Structured Assessment of Technical Skills (OSATS) score
\- A numbered score is computed from a global rating system based evaluation grid.
1 year
Participant classification
Blinded reviews will classify participants as junior residents, senior residents, fellows/staff based on their perception of participant skill level.
1 year
Secondary Outcomes (3)
Muscle Electromyography
1 year
Muscle activation symmetry
1 year
Upper body kinematics
1 year

Objective Feedback (Motion Capture)
OTHERParticipants in the objective feedback group will receive a report that compares their performance in Set 1 to that of the staff surgeons' using the target interval as a reference. Participants receiving objective feedback will then complete Sets 2 and 3 knowing what factors to improve upon.
No Feedback
NO INTERVENTIONParticipants receiving no feedback will complete all sets with no intervention.
Interventions
Participants assigned to the objective feedback group will be given a report after completing Set 1 and Set 2. This report will outline their performance for each significant factor (identified in Phase 1) relative to a target interval, derived from the staff surgeon group average (± one standard deviation). Participants assigned to the objective feedback group will then be able to repeat the tasks knowing which variables to improve.
Eligibility Criteria
You may qualify if:
