workers reported high frequencies of MSDs in the ‘back’
and in the ‘upper extremities’, and had high work
demands, they also had high level of control and support
and were satisfied with their work. The result of the
study showed no significant risk factors for MSD associated
with the psychosocial work environment which
suggests the probability that factors in the physical work
environment are more likely to lead to MSDs than factors
related to the psychosocial work environment.
