Quantitative posturagraphy as an alternative noninvasive tool for alcohol/drug/chemical testing--preliminary thoughts.
This article provides preliminary ideas regarding how the quantitative posturagraphy technique can be used as an alternative noninvasive tool to currently available blood/urine test for alcohol/drug/chemical exposure. It is argued that the urine or blood level of any chemical is highly dependent on the individual's metabolism without providing any insight into individual's task performance abilities under exposure to neurotoxic chemicals. On the other hand, the quantitative posturagraphy if carried out as proposed in this article will provide quantitative data regarding individual's ability to maintain "safe" upright balance while carrying out certain tasks. The proposed evaluation method is simple, portable, quick, and noninvasive and has been found to be sensitive to detecting low level solvent induced modifications in postural stability.
