usculoskeletal strain (MSS) is one of the mayor health
problems in office workers (OW), while in EU these affecting
millions of workers and cost companies a billion euros every
year. Working long time in sitting position in unergonomic
work postures causes MSS and working ability loss. The aim
of the present study is to evaluate musculoskeletal strain in
office workers association with working ability, and ergonomic
workplace environment conditions. All participants worked in
Estonian Government Buildings whole workday with computer in
sitting position. Participants filled modified Nordic questionnaire,
which evaluates MSS in last 30 days in eight different body
regions. Work ability was assessed by standardized questionnaire
(Finnish Institute of Occupational Health), where calculated work
ability index (WAI). Results showed that MSS in last 30 days was
localized primarily in low back (69%), in neck (67%), in shoulders
(56%), and in upper back (51%). Women perceived more MSS in
upper back (p=0.032), in shoulders (p=0.027), and in neck (0.002)
compared with men. OW-s average work ability according to WAI
was “good” (result±SD: 38±5). Lowest work ability index was
noted in age group 40-49 a (1%). OW-s, who weren’t satisfied with
their workplace ergonomics, perceived more MSS (p<0.05) (in
wrist, in upper back, in shoulders, and in low back In conclusion
office workers in Estonia perceived more musculoskeletal strain
in low back, in neck, in shoulder, in upper back, and in wrist.
Unergonomic workplace causes often MSS in OW. Work ability
loss is noted in individual office workers, starting at the age of
40. To avoid and prevent musculoskeletal strain it is obligatory to
evaluate workplace ergonomics, use ergonomic equipment, and
take rest breaks during workday.
