The REBA Method
The Rapid Entire Body Assessment (REBA) method uses a systematic process to assess the risks of MSD (Musculoskeletal Disorders) for the whole body and the risks associated with ergonomic design associated with work. It is an observation method sensitive to MSDs in different varieties of task. It divides the body into segments so that it can be noted individually, relative to the plane of movement. The REBA method provides a scoring system for muscle activity caused by static, dynamic, changing or unstable postures. It gives an intervention threshold with an indication of the emergency.

The REBA method is used to assess the different body postures required, energetic efforts, the type of movement or action, repetition and difficulty of taking. A score is assigned to each of the following body regions: wrists, forearms, elbows, shoulders, neck, trunk, back, legs and knees. The method tables are then used to compile the risk factor variables generating a single score representing the risk level of MSD.
Restrictions et limites
- The REBA method is not recommended for evaluating manual handling tasks.
- The REBA method examines strengths and activity, but it mainly focuses on work postures.
- It does not take into account the duration of the activity, the recovery period, or the vibrations.
- It is only designed to assess the right side and the left side of the body separately, and there is no method for combining scores to obtain a result for the whole body.
- The cumulative effects of all activities performed in the course of a job or task are not taken into account.
- The REBA method does not allow precise evaluation of the tasks linked to small manipulations of objects with the hands.
- It does not make it possible to assess tasks requiring long travel or very varied and unpredictable tasks.
- The REBA method lacks precision in analyzing the frequency of efforts or certain postures very specific to production.
STEP 1 - PREPARE
Determine the work cycle to be observed.
STEP 2 - OBSERVE
Select the posture to be evaluated. Decide which side of the body will be assessed or if too complex, assess both sides at the same time.
STEP 3 - ASSESS
Determine the score for each side of the body. Obtain the overall score and the associated risk level.
STEP 4 - ANALYSE
Review the scoring for each part of the body to determine where actions are needed.
STEP 5 - IMPROVE
Adapt the workstation and introduce improvements to the ergonomic risks identified.
STEP 6 - REASSESS
Once the changes have been made, reassess with the REBA grid to validate the results.
