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

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 Uplifter decreases the risk presented by the most dangerous lifts performed.
