Exposure
Daily duration of significant use of hand force – mean value.

The ratings of the hand-exposure were assessed by five experienced occupational physicians. They rated the daily duration of significant use of hand force in 33 job titles with representative goniometric measurements. This was rated in five categories and noted on rating cards for each job title scored 1-5. Each card included a short description of the work tasks performed during the measurements.

  1. No or an insignificant part of the time
  2. A small part of the time
  3.  Some of the time
  4. Much of the time
  5. Most of the time

The five categories were further split into two subcategories: low and high. The latter group was then scored with an addition of 0.5 points to the main category score, resulting in 10 scores (1– 5.5 by steps of 0.5 score points).

The combined mean value of the ratings was used as the exposure value.

Inspiration from research projects on physical workload in DOC*X

Within DOC*X, several research projects investigate the relationship between physical workload and health, where the Hand Strain is one of the exposures applied

Among these studies is research examining the association between treatment for pain in the distal upper extremities and repetitive or forceful hand movements. The study shows that men working with high hand strain have twice the risk of seeking treatment. The results for repetitive movements, however, are inconclusive. For women, no increased risk was found—neither for high hand strain nor for repetitive movements.

These are just a few examples of the research conducted within the DOCX framework. Here you can find more information on other research projects using DOCX data.
