Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them.
To achieve best practice design, Ergonomists use the data and techniques of several disciplines:
Low Back Pain (LBP) is an immense burden to the industry. Prolonged postures, awkward postues, repetitive lifting, heavy lifting, lifting in wrong posture, sedentary life style/occupation, personal risk factors of the person may all contribute to LBP (or back pain). Click Here.
Knees, ankles, elbows should all be at an angle little more than 90 deg (i.e relaxed). Arms should be straight or at 20 degree. Ankles should be in front of knees.

Leave a gap of 4 to 6 inches in front of your desk to rest your wrists while your type. Place a wrist rest if needed, to keep your wrists straight.
- Anthropometry: body sizes, shapes; populations and variations
- Biomechanics: muscles, levers, forces, strength environmental
- Physics: noise, light, heat, cold, radiation, vibration
- Body systems: hearing, vision, sensations
- Applied psychology: skill, learning, errors, differences
- Social psychology: groups, communication, learning, behaviours. Click Here.
