ACCUPRESSURE® back support

48030 (Black) Patent Pending

University research led to a new level of understanding of how lower backs function. With this research, Accupressure back supports were developed, bringing a unique technological solution to market and a new level of lower back protection to working people.
• Proprietary acupressure-effect pad made with composite lightweight materials works biomechanically to reduce the over-reaction of the back muscles during an unexpected loading event
• High density woven elastic cinch straps give superior performance consistent over long-term use
• Triple Lock cinch strap feature
• Variable number of spring steel orthopedic boning stays according to support size
• Quick-release shoulder straps provide flexibility and safety for wearers

From the Biomedical Engineering and Occupational & Environmental Health Departments at The University of Iowa, 2003.

"Our research ... evaluating the mechanical role of lumbar supports strongly suggests that lumbar supports produce a calming effect on the lumbar musculature's response to sudden loads applied at the hands or chest. As such, lumbar supports can act as a barrier, reducing the body's tendency to over-react to an applied sudden load."¹

Based on this research, The Spine Research Center at The University of Iowa worked with Chase Ergonomics, Inc. on the development of the Accupressure Back Support.
Sudden loads on the spine occur during an unplanned for accidental) event, and cause back muscles to overreact to a surprise by expending mean muscle forces which are on average 70% greater than the forces expended during a planned or expected 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 surprised to leam that excess back muscle contraction is the first incident triggering approximately 30% of all lower back injuries.
Testing has proven that the Accupressure, with its unique "pressure bumps" concentrated over targeted areas, creates the calming effect described in the above study. In tests at the Spine Research Center, Accupressure reduced the over-contraction of back muscles by up to 39% in men and 46% in women. Significant reduction of back muscle fatigue over a work cycle was also recorded.

IMPORTANT FEATURES TO LOOK FOR WHEN SELECTING A FLEXIBLE LUMBAR SUPPORT
Primary belt should:
• hold the orthopedic boning stays in the correct position on the lower back
• be of strong, breathable, open weave fabric for comfort
• stretch in all directions, return to its original size
• have two-way stretch binding on the edges
• fasten with a generous Velcro® closure
• increase in width in proportion to size.
Boning stays should:
• be of orthopedic-grade spring steel with dielectric coating
• flank the spinal column, not lie over it
• be almost the same length as the primary belt width
• increase in number as size of support increases
Cinch strap should:
• be of woven elastic in a preferred double V-shaped strap
• cover at least 90% of stay length to shape stays to body
Shoulder straps help:
• keep the support handy during breaks or non-lifting periods
• compliance—easy to tell if a required support is being worn
• adjust tension to a slightly stretched mode to prevent "blousing" when bending Shoulder straps are not suspender's and should not be adjusted so tightly that they pull the support up and out of position
