This study was conducted by Noel Lythgo, Senior Bio Mechanics Researcher Melbourne.
This work investigated the alignment of the body on 15 bed types that are commercially available.
Information about the position of the back (vertebral column), shoulders and pelvis in 3-dimensional space was recorded buy a VICON motion analysis system.
The results show the variable support system (ergonomics within a bed) to align the body in a position similar to that achieved when standing (neutral position).
This study was conducted by Dr Ray Hayek, Macquarie University, Sydney, School of Chiropractic.
A range of male and female subjects were tested on a bed unit without variable support (ergonomics within a bed) and then on the same bed unit with Variable Supported (ergonomics) introduced.
Use of variable support (ergonomics) showed the following benefits:
This study was conducted by Associate Professor Nicholas Haritos, Reader at Engineering – Melbourne University.
The study was conducted on the recognition of varying weight and shape of the human form, particularly noting the region of hips, lumbar and shoulders.
It was apparent that the supportive materials used in the mattress/bed construction must be able to:
Associate Professor Nicholas Haritos stated: “No mattress/bed construction with a flat surface and near uniform firmness can by itself be capable of supporting the human body in an orthopaedically correct (zero stress) posture.
