What is the difference between Rula and Reba?

In order to compare the differences between REBA and RULA scores, it was necessary to normalize the absolute values as the two methods are based on different scales: RULA has four risk levels that categorize scores from 1 to 7, while REBA is based on five levels of risk that categorize scores from 1 to 15.

How is RULA score calculated?

What is Reba and RULA?

RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) are the two easiest methods for postural risk assessment in the workplace. Few studies investigated postural risk in forestry sector with regard to human–machine interaction, in particular manually fed wood-chippers.

Which is better Reba or RULA?

In the comparison of the normalized numerical indices, all of the RULA scores were higher than the corresponding REBA scores for all of the tasks (Table 3). The application of RULA showed to be more precautionary than REBA for all the tasks, as it returned a higher score value in each loading.

What is Reba worksheet?

This ergonomic assessment tool uses a systematic process to evaluate whole body postural MSD and risks associated with job tasks. A single page worksheet is used to evaluate required or selected body posture, forceful exertions, type of movement or action, repetition, and coupling.

How do you use Reba worksheet?

REBA is a screening tool that assesses biomechanical and postural loading on the whole body….REBA has six steps:

  1. Observe the the task.
  2. Select the postures for assessment.
  3. Score the postures.
  4. Process the scores.
  5. Establish the REBA score.
  6. Confirm the action level with respect to the urgency for control measures.
