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.
