Ergonomics
The Accupressure® Back Support
|
From the Biomedical Engineering and Occupational & Environmental Health Department at The University of Iowa, 2003 |
Sudden
loads on the spine occur during an unplanned (or accidental) event, and
cause back muscles to overreact to a suprise by expending mean muscle
forces which are on average 70% greater than the forces expended during
a planned or exdpected loading of the spine. Anyone who has stepped off
a curb that is higher or lower than expected has experienced sudden
spinal loading, and won't be suprised to learn that excess back muscles
contraction is the first incident triggering approximately 30% of all
lower back injuries. |
