The use of PSSD testing in comparison to vibrotactile testing of vibration exposed workers.
With the acceptance of the Stockholm scale for the neurological effects of Hand-Arm. Vibration Syndrome, there has been increasing interest in selection of the appropriate screening and diagnostic procedures for worker evaluation. With the increased attention to worker surveillance to decrease morbidity, workers compensation and legal liability, a system that provides early detection as well as diagnostic specificity would be desirable. Up to now, most screening tests have suffered from lack of specificity or are time consuming in administration. Most diagnostic tests are too expensive or impractical to use on a screening basis. The Pressure Sensitive Sensory Device (PSSD) system with a modification of the two point discrimination system has been shown to be at least as effective in comparison to vibrotactile testing as well as less time consuming. In addition, the study shows that there is a favorable correlation between PSSD and nerve conduction studies. This system offers and effective method of evaluation of workers for the effects of Hand-Arm Vibration Syndrome as well as other ergonomically induced conditions such as Carpal Tunnel Syndrome. Studies of various population groups will be presented.
