In a study conducted by Choobineh et al [2] on 1,439 carpet
weavers, 15,368 days of reported sickness absence, due mainly to
the MSP, were recorded; 3.76% of the participants were not able to
get to their work during the previous 12 months. Based on the
results of this study, 2.2 million of Iranian carpet weavers are
suffering from musculoskeletal problems, also, these problems are considered to be the main reason for 23,496,000 working days
being lost [2].
