Depending on the training format and workplace activities, our Musculoskeletal Injury Prevention Training addresses important concepts including:
- What musculoskeletal injuries are.
- How musculoskeletal injuries can develop.
- Common workplace MSI hazards.
- The relationship between ergonomics and MSI prevention.
- Force and physical exertion.
- Repetitive movements.
- Awkward working positions.
- Static and sustained postures.
- Manual material handling.
- Lifting and lowering.
- Carrying materials.
- Pushing and pulling.
- Workplace and workstation design.
- Tool and equipment considerations.
- Vibration and other contributing factors.
- Recognizing early signs and symptoms.
- The importance of early reporting.
- Hazard identification and assessment.
- Eliminating or reducing unnecessary manual handling.
- Mechanical lifting and material-handling aids.
- Workplace design and engineering controls.
- Administrative controls and work practices.
- Safe manual handling principles.
- Worker responsibilities.
- Supervisor responsibilities.
- Workplace-specific MSI prevention.
The training emphasizes understanding the conditions creating the exposure, rather than relying exclusively on worker behaviour.
Common Musculoskeletal Injury Risk Factors
Musculoskeletal injuries usually aren’t caused by a single risk factor.
Several physical demands may occur together and increase the overall stress placed on the body.
Force
Force refers to the physical effort required to complete a task.
Workers may exert force while lifting, lowering, carrying, pushing, pulling, gripping, holding, or operating tools and equipment.
As the amount of force increases, so does the physical demand placed on muscles, joints, and other tissues.
Repetition
Repeatedly performing the same or similar movement can increase musculoskeletal stress.
The concern becomes greater when repetitive work is also forceful, performed from an awkward position, or completed with limited opportunity for recovery.
Awkward Postures
Bending, twisting, reaching, kneeling, squatting, working overhead, or performing tasks away from a comfortable body position can increase physical demands.
The amount of time spent in the position and how frequently the worker must assume it are also important.
Static or Sustained Postures
A worker doesn’t need to be moving continuously to experience musculoskeletal stress.
Remaining in the same position for an extended period can fatigue muscles and tissues.
This can affect workers performing physical jobs as well as employees who spend long periods sitting or using computers.
Manual Material Handling
Manual material handling can include lifting, lowering, carrying, pushing, pulling, holding, or moving materials.
The weight of a load is only one consideration.
Its size, shape, stability, location, grip, carrying distance, frequency of handling, and surrounding work environment can all affect the demands placed on the worker.
Vibration
Workers may be exposed to vibration through powered hand tools, machinery, vehicles, and other equipment.
Vibration can contribute to musculoskeletal concerns and may interact with other physical demands.
Multiple Risk Factors
The greatest concern often occurs when several risk factors exist at the same time.
For example, repeatedly lifting an object may involve force.
If the material is stored near floor level, the task may also involve bending.
If the worker needs to turn while lifting, twisting is added.
If the activity continues throughout the shift, repetition and duration also become factors.
Effective MSI prevention looks at the complete task rather than considering each movement in isolation.
