Abstract
|
|
|
Purpose: This study sought to determine how the act of performing cardiopulmonary resuscitation (CPR) affects the rescuer’s muscle tone, stiffness, and fatigue in the lumbar region.
Methods: The research subjects were 30 healthy men in their twenties in possession of a Basic Life Support (BLS) provider certificate. In this study, the CPR rescuer's muscle tone and stiffness in the upper and lower lumbar regions were measured in the resting position, starting position, and position after 10 min. Their level of fatigue was measured before and after performing CPR.
Results: Muscle tone and stiffness in the upper and lower lumbar regions of the research subjects significantly increased throughout the CPR process and lasted up to 10 min after the process (p<.001). The subjects’ fatigue also significantly increased post-CPR (p<.001).
Conclusion: This study suggests that performing CPR creates muscular and physiological stress, fatigue, and ultimately, lower back pain.
