RULA / REBA

RULA / REBA Ergonomic Risk Score Calculator

RULA = Rapid Upper Limb Assessment  |  REBA = Rapid Entire Body Assessment. Both are validated observational tools for scoring musculoskeletal disorder (MSD) risk from posture, force, and muscle activity — RULA focuses on the upper body for seated/desk-based tasks, REBA covers the whole body for a wider range of static and dynamic tasks. Select posture options from live observation, photos, or video; the calculator applies the official scoring tables automatically.
