Bending posture Ergonomics can be defined as aiming to design appliances, technical systems and tasks to improve human safety, health, comfort and performance.

In application, the ergonomic approach aims to adapt the workplace or environment to fit the individual.

Factors that play a role in ergonomics are:
Body Posture and movement – sitting, standing, lifting, pulling and pushing.
Environmental factors – noise, vibration, illumination, climate
Information and operation – information gained visually or through other senses; relation between displays and controls.

Seated posture Both at work and in our leisure pursuits we require our body’s to adopt various postures and produce movement. Our joints, muscles and ligaments are all involved continually in this process.

Poor posture and movement patterns can lead to mechanical stress on our body structures manifesting itself as pain. The most commonly affected areas are the spine, shoulders and wrists but any part of the musculoskeletal system can be affected.

To prevent unnecessary mechanical stress on the body the following factors should be taken into consideration:
  • Joints must be in a neutral position
  • Keep the work close to the body
  • Avoid bending forward
  • A twisted trunk strains the back
  • Lifting must occur as far as possible in an even and gradual manner
  • Alternate postures as well as movements
  • Limit the duration of any continuous muscular effort
  • Prevent muscular exhaustion
  • More frequent breaks are better than a single long one
