Question 1 Report
The diagram shows an ergonomic computer workstation.
(a) Using the diagram, describe two causes of back problems associated with prolonged computer use. [2]
(b) State three features of an ergonomic chair designed to prevent back problems. [3]
(c) Give one other piece of furniture or equipment that can help prevent back problems when using a computer. [1]
Answer Details
(a) Two causes of back problems associated with prolonged computer use, as illustrated in the diagram:
- Sitting in a chair that does not provide adequate lower back (lumbar) support allows the spine to curve unnaturally, leading to muscle strain and long-term spinal problems. [1]
- Sitting at an incorrect height relative to the desk causes the user to hunch forward or lean back awkwardly, straining the neck, shoulders and back. [1]
(b) Three features of an ergonomic chair designed to prevent back problems:
- Adjustable seat height so the user's feet can rest flat on the floor (or on a footrest) with thighs parallel to the ground. [1]
- Adjustable lumbar support that fits the natural inward curve of the lower spine, maintaining correct posture. [1]
- Adjustable armrests that allow the forearms to rest level with the desk surface without raising or tensing the shoulders. [1]
(c) One other piece of furniture or equipment that helps prevent back problems:
A footrest to support the feet if the chair height means the user's feet cannot reach the floor comfortably. The footrest, shown in the diagram, ensures the thighs remain horizontal. [1]
