C. Zetterberg et al., NECK AND UPPER EXTREMITY PROBLEMS IN CAR ASSEMBLY WORKERS - A COMPARISON OF SUBJECTIVE COMPLAINTS, WORK SATISFACTION, PHYSICAL-EXAMINATION AND GENDER, International journal of industrial ergonomics, 19(4), 1997, pp. 277-289
This study includes 564 car assembly workers, 440 men and 124 women, Q
uestionnaires, including work satisfaction, orthopaedic examination an
d exposure evaluation were performed. Women had more neck-myalgia and
more physical signs from the hands, especially nerve related problems
and tendinitis compared to men, Impingement of the shoulder was equall
y prevalent among women and men, doing the same work. Women showed a h
igher work satisfaction than men. Stress at work correlated both to su
bjective complaints from all locations in the upper half of the body a
nd to findings at the physical examination. A logistic regression anal
ysis showed that subjective complaints from the neck, shoulders and fe
et correlated to less good work satisfaction, while work dissatisfacti
on was not correlated to any of the physical signs, Those having stati
on-bound work showed less good relations to foremen/workmates and bett
er to the work in comparison with the workstations at the assembly lin
e, The questionnaire gave around 50% higher prevalence of pain from di
fferent body areas, when compared to the physical examination. The res
ult represent 23 workstations, constituting the assembly line, A great
variation of symptoms and signs was found, significantly so for subje
ctive pain in the wrists/hands (p<0.02), objective pain in the cervica
l spine (p<0.01) and shoulder impingement (p<0.01), Some specific ergo
nomic problems were found. A summary for each workstation was presente
d to the factory and some changes were accomplished. The quality of th
e production is, among other things, depending on healthy workers, hig
h work satisfaction, low workforce turnover, etc. This study shows how
the combination of questionnaires, including work satis faction, phys
ical examination and exposure evaluation can give possibilities to spe
cific intervention.
