Key Concepts

• Neutral posture (GOOD)– Halfway zone – Person’s ability to flex and extend– Comfortable working posture– Reduces risk of musculoskeletal

disorders

Key Concepts

• Static positions (BAD)– A working position with no motion– Muscles become fatigued.– Blood flow is reduced.

Computer Work Area

• Workstation guidelines– Top of monitor at or below eye

level– Align head and neck. – Relax shoulders.– Align wrists and hands

with forearms.

Computer Work Area

• Choose a chair with maximum adjustments. – Height– Seat depth– Seat angle– Lumbar support– Arm rests– Tilt

Computer Work Area

• Sit properly– Head balanced naturally over

shoulders – Shoulders relaxed, not hunched – Forearms and thighs parallel to the

floor

(Not like this)
