Abstract:

Aspects of this invention include new measures of hip—torso posture and strength of the legs. These new measures are made using new tools. Measurement of hip-torso posture can be made using simple tools. One such tool can be applied to the hips, and indicates relative angle of the spine. Photographic tools can be used to analyze posture relative to vertical references. Measurement of leg strength can be made using a device incorporating accelerometers and computer implemented instructions to quantify forward/backward, left/right, or rotational acceleration when the legs are challenged. Other aspects include devices with computer implemented instructions to quantify leg strength. Using the new devices and methods, one can objectively determine postures that are ergonomically appropriate for persons sitting and working at workstations.
