Summary
Firefighter-paramedics face high risks of musculoskeletal injuries. This study analyzed strenuous tasks, finding that standing improves posture during bed transfers and interface boards reduce strain. Forward-facing transport, especially downstairs, enhances safety.
Area of Science:
- Occupational Health
- Ergonomics
- Emergency Medical Services
Background:
- Paramedics performing emergency rescue are prone to musculoskeletal injuries.
- Firefighter-paramedics identified strenuous and frequent tasks through surveys.
Purpose of the Study:
- To describe working postures and forces during simulated emergency rescue tasks.
- To quantify strenuous moments during patient handling by firefighter-paramedics.
Main Methods:
- Ten two-person teams of firefighter-paramedics performed simulated patient transfers and transports.
- Videotaping captured upper and lower extremity postures; lumbar monitors tracked trunk posture.
- Hand-held dynamometers measured static hand forces at peak exertion points.
Main Results:
- Standing improved posture and stability compared to kneeling during bed-to-stretcher transfers.
- Interface boards can decrease friction, reducing torso and shoulder flexion during transfers.
- Forward-facing transport, particularly by the leader during stair descent, may improve transit safety.
Conclusions:
- Ergonomic interventions like interface boards and specific training can mitigate injury risks for firefighter-paramedics.
- Optimizing patient handling techniques and equipment can enhance safety during emergency rescues.
