Neck/shoulder discomfort due to visually demanding near work is influenced by previous neck pain, task duration, astigmatism, eye discomfort and accommodation.
(English)Manuscript (preprint) (Other academic)
Visually demanding near work can cause eye discomfort, and eye and neck/shoulder discomfort during, e.g., computer work are associated. Here, to investigate direct effects of experimental near work on eye and neck/shoulder discomfort, 33 individuals with chronic neck pain and 33 healthy control subjects performed four visual tasks, rating eye and neck/shoulder discomfort at baseline and after each task. The cumulative performance time (reflected in the temporal order of the tasks), astigmatism, concurrent eye discomfort, and extent of accommodation all aggravated neck/shoulder discomfort. There was an interaction effect between the temporal order and eye discomfort: participants with a greater mean increase in eye discomfort also developed more neck/shoulder discomfort with time. Since moderate musculoskeletal symptoms are a risk factor for more severe symptoms, it is important to ensure a good visual environment in occupations involving visually demanding near work.
