Evaluation of ergonomic dental stools through clinical simulation.
Work-related musculoskeletal pain occurs commonly within the dental community. Three stool designs were utilized in this study: a standard dental stool, a stool with dual arm supports, and a stool with dual arm supports and chest support. Electromyographic data from four muscle groups were collected on 13 clinicians during a simulated crown preparation procedure. Clinical simulation suggests that a potential musculoskeletal benefit to the clinician exists through utilization of dental stool designs which incorporate static arm supports.
