Ja. Paul et al., WORK LOAD AND MUSCULOSKELETAL COMPLAINTS DURING PREGNANCY, Scandinavian journal of work, environment & health, 20(3), 1994, pp. 153-159
OBJECTIVES - Many pregnant women have musculoskeletal complaints, the
onset and aggravation of which are thought to be associated with their
activity or work postures. The purpose of this paper was to obtain mo
re insight into the influence of pregnancy on the load of the musculos
keletal system at work to provide a better basis for preventing compla
ints. METHODS - To this end, literature pertinent to a model called ''
work load of the musculoskeletal system'' was reviewed. The model was
developed to describe how work contributes to musculoskeletal complain
ts. RESULTS - It was found that pregnancy causes changes in a worker's
characteristics. These changes can lead to changes in the work situat
ion, activity pattern, and postural characteristics and possibly resul
t in a change in work load. In addition, physical changes such as weig
ht gain increase the work load in a given posture. The load-bearing ca
pacity of the musculoskeletal system decreases due to pregnancy. CONCL
USIONS - The changes in load and the decrease in load-bearing capacity
singly or simultaneously increase the risk of musculoskeletal complai
nts. The multifactorial cause of musculoskeletal complaints during pre
gnancy reveals various possibilities for prevention.
