Rapid Upper Limb Assessment (RULA) is a method to identify postural stress of upper limbs that
was originally developed by McAtamney & Corlett [16]. The risk is calculated into scores and
classified into four action levels. A RULA sheet consists of body posture diagrams and scoring
tables. Based on the RULA method, the human body is divided into two parts, which are part A
for Arm and Wrist analysis while part B for Neck, Trunk and Leg Analysis. A scoring system is
used to assign scores at every step, depending on the body position, with the higher scores for
more awkward postures. RULA method is widely used in ergonomic field.
