Hignett & McAtamney [10] developed the Rapid Entire Body Assessment (REBA) method. Unlike
RULA method that focused on sedentary tasks, REBA method assesses the whole body. The risk
calculates into the score with five action levels. A REBA sheet consists of body posture diagrams
and three scoring tables. The human body is divided into two parts, which are part A for Neck,
Trunk and Leg analysis while part B is for Arm and Wrist Analysis. A scoring system is used to
assign scores at every step. The process depends on the specific body position, showing higher
scores for more awkward postures. Both methods have categorized action levels to indicate
action requirement. Table 1 and 2 show the action levels for each score.
