About

Ranah Lim is a pioneering researcher in the field of surgical ergonomics, with a specific focus on robotic colorectal surgery. Her work addresses the critical issue of surgeon well-being and performance by investigating the physical factors that contribute to musculoskeletal strain during minimally invasive procedures. Lim’s major contributions include identifying key determinants of suboptimal hand positioning, such as patient anatomy and console setup, which can lead to ergonomic risk. She also introduced the concept of visual perception mismatch (VPM), demonstrating that surgeons’ hand positions often do not align with their visual field, a finding that has reshaped training protocols. Her randomized controlled study on forearm compression sleeves showed a statistically significant reduction in muscle fatigue, offering a practical intervention for surgical teams. With over 11 citations across her most-cited papers, Lim’s work is gaining traction among surgeons and ergonomics specialists. Notably, her 2023 study on upper limb ergonomics has become a foundational reference for designing safer robotic surgery environments, highlighting her impact on both clinical practice and occupational health.
