Hand function tests and questions on hand symptoms as related to the Stockholm workshop scales for diagnosis of hand-arm vibration syndrome.

The severity of hand-arm vibration syndrome (HAVS) is usually graded according to the Stockholm workshop scales. Although the Stockholm workshop scales are regarded the gold standard for assessing the severity of HAVS, they are based primarily on subjective symptoms. The aim of the present study was to explore the agreement between Stockholm workshop scales and the outcome from ten well-defined clinical tests commonly used in hand rehabilitation for assessment of hand function. One hundred and eleven vibration-exposed workers participated in the study. Ten objective tests of hand function and four questions on subjective hand symptoms were included. The results indicated that, out of these tests, perception of vibration, perception of touch/pressure and dexterity showed a moderate agreement with Stockholm workshop scales. Among specific questions on hand symptoms, cold intolerance and pain showed a high agreement with Stockholm workshop scales. It is concluded that defined objective tests combined with directed questions on specific hand symptoms, together with the Stockholm workshop scales, may be helpful for diagnosing HAVS.

Hand-arm vibration exposure influences performance of daily activities.

PURPOSE: Although much research has been performed on the effects of vibration on nerves, muscles and vascular structures, little is known of the effects that vibration exposure to handheld tools can give on the ability to perform activities of daily living. The objective of the present study was to analyse the consequences of vibration exposure on performance of daily activities. METHOD: In a total group of 105 exposed male workers, a standardized self-administered ADL questionnaire, the EDAQ including 102 activity items plus 22 diagnosis-specific activity items, was filled out. RESULTS: Forty-four workers (42%) expressed one or more difficulties in performing daily activities in the total study group. The data demonstrated that pain and reduced grip force showed a strong correlation with difficulties in performing daily activities. CONCLUSION: Working in a cold environment, using vibrating machines. handwriting, picking up small objects, opening lids, lifting and carrying were activities perceived as most difficult to accomplish.

Hand function in workers with hand-arm vibration syndrome.

Hand-arm vibration syndrome has been specially addressed in the Scandinavian countries in recent years, but the syndrome is still not sufficiently recognized in many countries. The object of this preliminary study was to describe the nature and character of vibration-induced impairment in the hands of exposed workers. Twenty symptomatic male workers (aged 28 to 65 years) subjected to vibration by hand-held tools were interviewed about subjective symptoms and activities of daily living and were assessed with a battery of objective tests for sensibility, dexterity, grip function, and grip strength. The test results were compared with normative data. The majority of patients complained of cold intolerance, numbness, pain, sensory impairment, and difficulties in handling manual tools and in handwriting. The various objective tests showed considerable variation in indications of pathologic outcome, revealing differences in sensitivity to detect impaired hand function. Semmes-Weinstein monofilament testing for perception of light touch-deep pressure sensation, the small-object shape identification test, and moving two-point discrimination testing for functional sensibility provided the most indications of pathologic outcomes. The authors conclude that vibration-exposed patients present considerable impairment in hand function.
