low back impact assessment
of uplifter handcart
Study by Dr. W.S. Marras in the Biodynamics Laboratory at The Ohio State University
Objective of Study:
Determine whether or not using an Uplifter model handcart
has a significant impact on lower back forces compared to a traditional model
has a significant impact on lower back forces compared to a traditional model
Executive Summary:
- Between the Uplifter and standard handcart models, the Uplifter reduced spinal loads significantly on lifts 6 and 7 (the lowest lifts) in all three forces modeled (lateral, compression, and anterior-posterior shear)
- The analysis provided peak loads in compression, anterior-posterior shear, and lateral shear, for each of the six discs in the lower back
- The analysis provided peak loads in compression, anterior-posterior shear, and lateral shear, for each of the six discs in the lower back
Conclusion:
The Uplifter decreases the risk presented by the most dangerous lifts performed.
