Objectives/Hypothesis To evaluate muscle fatigue and participant pain in the upper back, cervical, and arm muscles associated with microlaryngeal surgery (MLS) in standardized favorable and unfavorable ergonomic positions. Study Design Individual randomized counterbalanced design. Methods Electromyographic sensors were placed on targeted muscles involved with performing MLS on 18 otolaryngology residents/fellows. Subjects were randomly counterbalanced in both favorable and unfavorable positions while completing simulated laryngeal microsurgical tasks. Participants reported their extent of muscle discomfort in targeted muscle regions on a standardized survey. Results Muscle fatigue and self-reported pain were reduced, and productivity was improved in the favorable position. In the lower trapezius, significantly less muscle activation (P = 0.025) and less pain (P |
