Data analysis showed significant differences(P_value Acoording to QEC method, 83 maintenance workers ( 65.87%) were at high risk and prevalence of lower back and knee was high that applying of simple and inexpensive solutions, participatory solutions of Ergonomics Checkpoint andselective corrective exerciselead to musculoskeletal disorders reduction.
