A study of various function tests on the upper extremities for vibration syndrome
American Industrial Hygiene Association Journal
|December 1, 1981
Summary
Early diagnosis of vibration syndrome is possible by detecting functional disorders using peripheral circulation, sensory, and motor tests. These tests are significant for screening, even without organic changes, and help understand independent symptom progression.
Area of Science:
- Occupational Health
- Neurology
- Physiology
Background:
- Vibration syndrome presents insidious functional disorders without early organic changes.
- Early detection is crucial for managing vibration-induced injuries.
- Standardized functional tests are widely used in Japan for upper extremity assessment.
Purpose of the Study:
- To evaluate the diagnostic significance of functional tests for early vibration syndrome detection.
- To analyze the progression patterns of peripheral circulation, sensory, and motor disturbances.
- To investigate the influence of work conditions on vibration syndrome manifestations.
Main Methods:
- Functional tests including peripheral circulation, sensory tests (with cold water immersion), and motor capacity tests were administered.
- Workers exposed to different vibration levels and control groups were examined.
- Principal component analysis was employed for data analysis.
Main Results:
- The function tests demonstrated diagnostic significance as a screening tool for vibration syndrome.
- Peripheral circulation, sensory, and motor disturbances appear to advance independently.
- Variations in vibration syndrome findings correlated with differences in work conditions.
Conclusions:
- Functional tests are valuable for the early screening of vibration syndrome.
- The independent progression of circulatory, sensory, and motor deficits is suspected.
- Work conditions significantly influence the presentation of vibration syndrome.
