Objectives:
Emergency personnel, including firefighters, play a crucial role in providing emergency care in diverse and challenging environments. With over 1,058,700 active firefighters in the United States, occupational safety assessment is vital due to high injury rates, especially from overexertion. By analyzing muscle activity and video feedback, this study aimed to improve first responders' occupational health and safety during lifting and transferring of patients.
Methods:
This study focused on 37 first responders from the City of Fairfield Fire Department, Ohio. Participants underwent video-assisted feedback sessions aimed at improving body mechanics during sit-to-stand transfers. Surface electromyography measured erector spinae (ES) and gluteus maximus (GM) muscle activation preintervention and post-intervention.
Results:
Statistical analysis revealed no significant difference in ES or GM muscle activation levels post-intervention. However, participants showed improved bilateral muscle activation symmetry, potentially reducing strain during lifting tasks. Video feedback emphasized neutral spine positioning, proximity to patients, and proper hand placement, aligning with ergonomic principles.
Conclusions:
While statistical significance in muscle activation levels was not achieved, improved symmetry suggests potential benefits in injury prevention. Video feedback, coupled with expert guidance, enhances awareness of ergonomic techniques among first responders, promoting safer work practices.
