Objectives . This study aimed to investigate the effects of a physical activity and ergonomics improvement program (PAEIP) on employees’ musculoskeletal pain.  Methods.  The sampling group included 120 employees who met the criteria and were randomly assigned to the intervention group ( n  = 57) and the control group ( n  = 63). The visual analog scale, the Nordic musculoskeletal survey and rapid upper limb assessment (RULA) were used for collecting data.  Results.  When pre-test and post-test pain scores of the intervention group were compared, the average post-test scores were significantly lower in the neck, shoulder, wrist and lower back regions than the pre-test scores. When the intervention and control group RULA scores were compared, in the intervention group the proportion of employees found in an ‘acceptable posture’ level was 0% in the pre-test and 5.3% in the post-test, and in the same group the proportion of employees in the ‘further investigation and change may be needed’ level was 31.6% in the pre-test and increased to 61.4% in the post-test.  Conclusion.  As a result, the PAEIP has been found effective in reducing the ergonomic risks associated with upper extremities and rate or intensity of musculoskeletal pain.
