A Guide to Rapid Entire Body Assessment (REBA)

Musculoskeletal disorders (MSDs) cover a wide range of injuries and pain affecting your body’s movement system – the bones, muscles, joints, ligaments and tendons. Anyone can experience MSDs, from office workers to athletes, and they often stem from factors in our work and daily lives. In the UK in 2022/23, 1.8 million workers suffered from new or long-standing work-related illnesses, of which 27 per cent were MSDs. MSDs might seem like minor annoyances at first but, left unchecked, they can lead to chronic pain, decreased mobility and even lost time at work. In 2022/23 6.6 million working days were lost due to the disorder in the UK. Similarly, in 2021/22, there were 976,090 MSD cases that resulted in employees having days away from work, job restrictions or job transfers, with a further 502,380 cases where they took days off work as a result. It is clear that MSDs can have adverse effects on organizations and employees, both physically and financially; however, understanding the risks of MSDs is the first step towards prevention. This is where rapid entire body assessment (REBA) comes into play. The following guide is a tool to help organizations understand REBA in detail and how it can be used to foster healthier and safer workplace environments around the world.

What is rapid entire body assessment (REBA)?

Developed by Hignett and McAtamney, REBA became a means of assessing the entire body posture for risk of work-related musculoskeletal disorders. REBA was developed to fill a perceived need for a practitioner’s field tool, specifically designed to be sensitive to the type of unpredictable working postures found in healthcare and other service industries. Today, it serves as an invaluable tool in ergonomics, offering a swift and comprehensive evaluation of physical strain that workers can encounter when performing certain tasks across a wide range of sectors. REBA implements a systematic approach to analyze body postures and movements that are associated with biomechanical and musculoskeletal risks. Through a straightforward scoring system, practitioners can promptly identify any potential ergonomic hazards and enforce timely interventions. By combining observational data with a standardized algorithm, REBA facilitates a holistic examination of an individual’s entire body, ensuring a nuanced understanding of occupational biomechanics. As a user-friendly and efficient protocol, REBA stands as a vital resource for organizations committed to optimizing ergonomic conditions and prioritizing the well-being of their workforce.

By following the simple steps below, the entire team can work together to effectively prepare for the assessment. This can enhance the effectiveness and efficiency across the complete process to ensure a healthier workplace.

Select a qualified assessor: While anyone can technically attempt a REBA by following the standardized scoring system and instructions available online, using a qualified professional is highly recommended. Selecting a trained and certified REBA assessor is crucial to gaining a holistic understanding and recommendations. They will possess the necessary expertise to accurately assess postures, assign scores and interpret the final risk level. Professionals with the relevant qualifications can be found from ergonomics or occupational health organizations such as the Board of Certification in Professional Ergonomics in the US and The Chartered Institute of Ergonomics and Human Factors in the UK.

Identify tasks for assessment: Prioritize tasks with high risk factors for MSDs, such as those involving repetitive movements, awkward postures or heavy lifting. Speak to employees or safety representatives to gain insights into potential problem areas.

Gather information and resources: Provide the assessor with relevant background information about the tasks being assessed, including job descriptions, work procedures and any existing risk assessments. Additionally, ensure the assessor has access to any necessary equipment, such as observation checklists or scoring sheets. It’s also useful for the organization and employees to familiarize themselves with the REBA scoring system and guidelines to enhance the efficiency of the assessment. 

Engage with employees: Communicate openly and be transparent with employees about the purpose and benefits of the assessment. Encourage them to participate actively by providing their insights and experiences of the tasks being evaluated.

Employee preparation

Be informed: Familiarize yourself with REBA’s purpose and process. Understanding the benefits of these evaluations can foster a more positive and collaborative environment.

Be prepared to answer questions: The assessor might enquire about your experiences with the tasks being assessed, any discomfort you’ve encountered and suggestions for improvement. Providing accurate and honest information is crucial for a thorough evaluation.

What happens during a rapid entire body assessment?

A qualified professional will observe an employee performing a specific task, focusing on their posture, muscle activity, forced exertion, coupling with objects and other risk factors associated with potential MSDs during the REBA process. A score is then assigned to each aspect of the task being observed based on standardized criteria. The scores are then combined to generate a total REBA score, which corresponds to a risk level and suggested actions required. The REBA Employee Assessment Sheet can be viewed here.

Observing the body’s entire process provides a comprehensive understanding to identify potential hazards. This process allows early intervention and proactive measures to mitigate the risk of MSDs and incidents.

Interpreting the results of a REBA

After conducting the assessment using the predetermined scoring criteria, the REBA results provide valuable insights for both the employee and the organization. The final score, ranging from 1 to 15, directly translates to a risk level. Lower scores (typically below 4) indicate a minimal risk of MSDs associated with the evaluated task. This signifies a more ergonomic and comfortable work environment for the employee.

However, scores in the higher range (above 4) suggest a need for intervention. The REBA system doesn’t simply provide a single number; it offers a breakdown of the contributing factors through the individual posture scores. This detailed information empowers safety professionals and ergonomists to identify specific areas of concern. For instance, a high score for trunk posture in a construction worker might indicate awkward bending while lifting heavy objects. By analyzing these body-specific scores alongside the overall risk level, targeted recommendations can be formulated. These might include implementing lifting techniques that emphasize leg strength, utilizing mechanical assistance for heavy objects or providing padded knee pads for tasks requiring frequent kneeling. By addressing these specific concerns, the organization can minimize discomfort and optimize the employee’s well-being, ultimately fostering a safer and healthier work environment for everyone.
