Musculoskeletal Assessment in ERA

Initial Ergonomic Risk Assessment is assessed by looking at seven (7) ergonomic risk factors classified in the Guidelines of Ergonomics Risk Assessment at the Workplace 2017. Ergonomics risk factors are factors or hazards that may cause ergonomic-related issues such as body discomfort, sickness, pain as well as injuries due to improper working behavior that may affect the muscle, joints, or bones.


Ergonomic Risk Factors consist of different elements which are:


Ergonomic risk factors (Awkward posture, static posture, forceful exertions, repetitive motion, vibration, contact stress, environmental factors)
Ergonomic Risk Factors (ERF)

The 7 Ergonomic Risk Factors in the Initial Ergonomic Risk Assessment (INERA)

The Ergonomic Risk Factors are based on the Guidelines of Ergonomics Risk Assessment at the Workplace 2017.


1. Awkward / Poor Posture

Doing work-related tasks that require a body position other than neutral, such as twisting, bending, overreaching, arm abduction, head bending and others.


2. Static and Sustained Posture

Working for an extended amount of time while maintaining a specific position with little to no movement, such as continuous standing or sitting for a long period of time.


3. Forceful Exertions

Forceful exertions are where high-level force is applied when moving or supporting any weight, including when lifting, lowering, carrying, pushing, pulling and moving it with one's hands or by using one's body.


4. Repetitive Motions

Working for a long time which involves repetitive sequences of movement using joints and muscle actions.


5. Vibration

Performing tasks that expose the workers to kinetic energy from vibrating surfaces or tools, such as hand-arm vibration (HAV) and whole-body vibration (WBV).


6. Contact stress

Refers to either internal contact stress, where a tendon, nerve, or blood vessel is stretched or twisted around a bone or tendon, or external contact stress when a portion of the body scrapes against a component at the workplace.


7. Environmental risk factors

People's comfort, activity, and health might be impacted by working in a poor environment such as inadequate lighting or air ventilation, extreme temperature and excessive noise.



It is important to monitor ergonomic-related issues especially Ergonomic Risk Factors (ERF) at your workplace to ensure your employees are always in a healthy and productive condition.
