QST is a potentially useful tool for measuring sensory impairment for clinical and research studies. However, QS%R results should not be the sole criteria used to diagnose pathology. Because malingering and other nonorganic factors can influ ence the test results, QST is not currently useful for the purpose of resolving medicolegal matters. Well-designed studies comparing different QST devices and methodologies are needed and should include patients with abnormalities detected solely by QST. |
