as illustrated in table 4,
showed no significant difference in REBA and QEC
final scores between workers without and with 1 to 8
musculoskeletal disorders in body parts. Since such
relation has not been investigated in other studies,
we could not have a comparative assessment. The
lack of relation between and consistency of REBA
and QEC final scores in workers with 0-8 reported
WMSDs in various body parts can be attributed to
adverse signs of WMSDs in studied workers.
