Summary
Manual lifting techniques for nurses often exceed safe spinal force limits. Asymmetrical lifting and back rotation reduce perceived exertion and strain, with the Australian lift being less strenuous.
Area of Science:
- Occupational health
- Ergonomics
- Biomechanics
Background:
- Manual lifting by nurses poses significant physical exertion risks.
- Previous studies highlight the potential for spinal injury due to high compressive forces.
Purpose of the Study:
- To evaluate five two-person manual lifting techniques for nurses.
- To analyze physical exertion, biomechanical forces, and perceived exertion during patient handling.
Main Methods:
- Laboratory study involving ten female nurses and two passive patients (55kg, 75kg).
- Video recording of postures and motions for anatomical-biomechanical analysis.
- Measurement of perceived exertion using Ratings of Perceived Exertion (RPE) scores.
Main Results:
- Compressive spinal forces frequently exceeded the acceptable limit of 3425 N.
- Asymmetrical lifting techniques resulted in lower RPE scores and subjective stress compared to symmetrical techniques.
- The Australian lift demonstrated low compressive forces and moderate perceived exertion, while the barrow lift was most strenuous.
Conclusions:
- Biomechanical findings align with nurses' subjective perceptions of exertion.
- Asymmetrical lifting and back rotation are recommended to reduce physical strain and injury risk in nursing.
- The Australian lift technique is a potentially safer alternative for patient handling.
