Neck pain is a common complaint resulting from disorders of any muscles, nerves and bones in the neck. The pain can be work-related (e.g. due to neck muscles that are strained due to poor work postures such as hunching over a computer or work bench) and non-work-related (e.g. due to a driving accident in which a car is rear-ended, resulting in whiplash). IWH research seeks to determine the work-related risk factors for neck pain, how many workers report it, and how to best treat it to ensure a safe and timely recovery and return to work.
