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...

The foresters workers are especially exposed to hand-arm transmitted vibrations. These vibrations can cause the complex of vascular, neurological and musculoskeletal disorders, collectively named hand-arm vibration syndrome. Among these, the most common disorder is the vibration-induced white finger. The group exposed to vibration included: 4 hand saws cutters, 5 electric saws cutters, 3 tracto...

A series of 685 x-ray films of the cervical spine obtained in coal miners was analyzed to explore the occurrence of narrowed disc spaces and osteophytes in this occupational group, and to examine the association of x-ray changes with age, duration of employment, and duration of occupational exposure to hand-arm vibration. All data were extracted from individual medical files of coal miners exam...

Exposure to vibration transmitted to the hands and arms may increase the risk of developing chronic disorders. Current ISO standards regarding exposure are based in part upon assumptions regarding the relationship between threshold measurements and subjective experiences of vibration at higher intensity levels. This study investigated this relationship by comparing absolute threshold levels at ...

A methodology for measuring the vibration energy absorbed into the fingers and the palm exposed to vibration is proposed to study the distribution of the vibration energy absorption (VEA) in the fingers-hand-arm system and to explore its potential association with vibration-induced white finger (VWF). The study involved 12 adult male subjects, constant-velocity sinusoidal excitations at 10 diff...
