Ergonomic risk for surgeons is elevated during common otolaryngology procedures; current ergonomic interventions lack the ability to provide real-time feedback. The ability to quantify and mitigate ergonomic risk during surgery may reduce work-related musculoskeletal disorders.<\/jats:p><\/jats:sec>Objective<\/jats:title>To quantify the association of vibrotactile biofeedback with intraoperative ergonomic risk to surgeons during tonsillectomy.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>This cross-sectional study was conducted between June 2021 and October 2021 at a freestanding tertiary care children\u2019s hospital and included 11 attending pediatric otolaryngologists.

Assessment tools included the Rapid Upper Limb Assessment, craniovertebral angle, and time spent in an at-risk posture.<\/jats:p><\/jats:sec>Results<\/jats:title>Eleven surgeons (mean [SD] age 42 [7] years; 2 women [18%]) performed 126 procedures with continuous posture monitoring in the presence (80 [63%]) and absence (46 [37%]) of vibrotactile biofeedback. No complications or delays associated with the device were reported. Intraoperative vibrotactile biofeedback was associated with improved Rapid Upper Limit Assessment neck, trunk, and leg scores by 0.15 (95% CI, 0.05-0.25), improved craniovertebral angle by 1.9 (95% CI, 0.32-3.40), and decreased overall time spent in an at-risk posture by 30% (95% CI, 22%-39%).<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>The results of this cross-sectional study suggest that use of a vibrotactile biofeedback device to quantify and mitigate ergonomic risk for surgeons is feasible and safe while performing surgery. Vibrotactile biofeedback was associated with reduced ergonomic risk during tonsillectomy and may have a role in improving surgical ergonomics and preventing work-related musculoskeletal
