Purpose: We aimed to investigate trunk angle and muscle activation of the extremity and back toevaluate the effect of chest compression on work-related musculoskeletal disorders in 119 emergencymedical technicians (EMTs). Methods: Eighteen 119 EMTs performed 2-minute chest compression without interruption on acardiopulmonary resuscitation manikin, during which we measured changes in the trunk and shoulderjoint angles, muscle activation (triceps brachii, biceps brachii, erector spinae, gluteus maximus,pectoralis major, rectus abdominis, and rectus femoris) and chest compression accuracy. Results: The decrease in trunk angle by trunk muscle activation was the highest in event 2, the majordirection of chest compression. Both shoulder joint angles had no significant difference. Muscleactivation of the triceps brachii (p < .01), biceps brachii (p < .05), rectus abdominis (p < .05) and rectusfemoris (p < .01) significantly increased during the compression phase compared with the decompressionphase, with the rectus femoris showing an increase of 19%. Muscle activation of the erector spinaesignificantly increased in the decompression phase compared with the compression phase (p < .01). Conclusion: 119 EMTs mainly use the triceps brachii, biceps brachii and pectoralis major muscles duringchest compression.
