BACKGROUND We systematically reviewed etiological factors of Kienböck's disease (osteonecrosis of the lunate) discussed in the literature in order to examine the justification for including Kienböck's disease (KD) in the European Listing of Occupational Diseases. METHODS We searched the Ovid/Medline and the Cochrane Library for articles discussing the etiology of osteonecrosis of the lunate p...

The research performed in the domain of human body vibrations revealed their important influence on human health, being the origin of several professional diseases. Consequently, the vibrations influence can be clearly systematized in two distinct categories: whole body vibrations – with significant effects in the entire human body; vibrations on different sections of the body – that transmit s...

BACKGROUND Peripheral neuropathy is one of the principal clinical disorders in workers with hand-arm vibration syndrome. Electrophysiological studies aimed at defining the nature of the injury have provided conflicting results. One reason for this lack of consistency might be the sparsity of published longitudinal etiological studies with both good assessment of exposure and a well-defined meas...

An inverse eigenvalue problem approach to system design is considered. The Cayley-Hamilton theorem is developed for the general case involving the generalized eigenvalue vibration problem. Since many solutions exist for a desired frequency spectrum, a discussion of the required design information and suggestions for including structural constraints are given. An algorithm for solving the invers...

This paper addresses issue of flexible object manipulation by using robot arms. The main objective is to establish a suitable control system of the robot for performing flexible object manipulation tasks. A force sensor equipped at the wrist of the robot arm is used to measure the vibration of the flexible object. A vibration control scheme is designed based on linear feedback of vibration meas...

Hand-arm vibration syndrome (HAVS) is a symptom entity that consists of disturbances in the circulation of the fingers (Vibration White Finger or VWF), peripheral nerves of the hands and arms, and possibly muscle, joint and autonomic nervous system disorders. Changes in HAVS were assessed in a cross-sectional and in a longitudinal study of forestry workers. Sensorineural and musculoskeletal sym...

Muscle spindle afferents are known to influence the conscious appreciation of limb position. If a limb muscle is mechanically vibrated while the limb is physically restrained from moving under the action of the resulting tonic vibration reflex, illusory motion of the limb will be experienced in the direction that would be associated with stretch of the vibrated muscle. Two experiments are prese...

Prolonged exposure to hand-arm vibration (HAV) due to use of hand-held power tools leads to an increased occurrence of symptoms of disorders in the vascular, neurological, and osteo-articular systems of the upper limbs called hand-arm vibration syndrome (HAVS). Biodynamic responses of the hand-arm system to vibration can be suggestive parameters that give us better assessment of exposure to HAV...

Forestry workers are exposed occupationally to a number of harmful or harmful factors in their working environment (whole body and hand-arm vibration, acoustic and infrasonic noise, biohazards, musculoskeletal loads and other) that may cause a variety of workrelated or occupational diseases (e.g. vibration syndrome, noiseinduced hearing loss, hand-arm, infectious and parasitic diseases, allergi...
