“…New measurement systems have shown promising results, e.g., the wavelet analysis, which has been useful for analysing physiological systems. 33 One advantage over classical sign analysis is the possibility to detect and analyse nonstationarity in signals. The technique was introduced in the early 1900s by Alfred Haar but has developed significantly since then and has become one of the most efficient tools for signal and image processing.…”

The aim was to compare the prevalence of vibration related symptoms and signs in two groups of vibration exposed male workers: 36 vibration exposed patients and 33 truck mechanics. All participants answered a questionnaire, passed a structured interview about work and medical history and several neurophysiological tests. The prevalence of vibration white fingers (VWF) and neurosensory symptoms was significantly higher among the exposed patients than among the truck mechanics. One neurosensory examination method identified 46% of the exposed patients with numbness and tingling, three methods up to 85%. In the total material logistic regression showed that age and increased cold sensitivity were significant predictors of both neurosensory disturbances and vibration white fingers. Muscle cramps in arms and hands, pain in hands and age were significant predictors of reduced grip strength. The differences between the two groups were more pronounced for category variables than for continuous variables.
