Normal nerve conduction velocity and vibrotactile perception thresholds in computer users.

OBJECTIVES: A literature report described significantly raised vibration threshold within the territory of the median nerve in a group of office workers and concluded that the results indicated a change in the function of large sensory fibres. The aim of the present cross-sectional study was to compare vibrotactile perception thresholds and nerve conduction measurements in the upper extremity between female computer users (secretaries) and female non-users (nurses). METHODS: Eighty-two secretaries, aged 25-65 (median 44) years and 35 nurses, aged 24-57 (median 46) years went through nerve conduction measurements on the dominant hand and also a vibration threshold test with readings over the hand at five sites which tested cutaneous innervation of the median, ulnar, and radial nerves. RESULTS: There was no significant difference in any parameter of the nerve conduction testing and there was no significant difference in any parameter of the vibration threshold test between secretaries and nurses. The numerical differences between groups were small and in both directions and thus do not indicate a power problem. CONCLUSIONS: We saw no signs of early neural deficits of large sensory fibres in subjects who intensively use computer keyboard equipment.

Bicycle ergometer test to obtain adequate skin temperature when measuring nerve conduction velocity.

OBJECTIVE: To achieve optimal diagnostic accuracy, measurements of nerve conduction velocity require standardised tissue temperatures. To warm an extremity to a desired temperature that remains constant during the measurement may be difficult, especially in subjects with low finger temperatures. The aim of this study was to investigate if a submaximal bicycle ergometer test before the examination would be a useful method of obtaining high and stable finger temperatures during nerve conduction studies in the hand. METHODS: 114 women aged 25-65 (median 44) performed a bicycle ergometer test on an electrically braked bicycle ergometer (Siemens-Elema) before they underwent a nerve conduction test. RESULTS: Before cycling, the mean finger temperature was 28.1 degrees C (range 20.5-35.4 degrees C) and 15 min after the test 35.1 degrees C (range 30.3-36.9 degrees C). The levels remained almost constant throughout the nerve conduction examination, which had a duration of approximately 25 min. CONCLUSIONS: A bicycle ergometer test proved to be a simple and effective method of raising hand temperature.

The Quebec classification and a new Swedish classification for whiplash-associated disorders in relation to life satisfaction in patients at high risk of chronic functional impairment and disability.

Unlike the Quebec classification system, which is based primarily on pathoanatomy, a new Swedish classification system is based on the site of functional impairment and disability. A prospective study was performed on 85 patients with whiplash-associated disorders grade II according to the Quebec classification. The patients were examined 3-36 months following trauma. A team of professionals with different training performed the diagnostic procedure. An independent assessor classified these patients according to a Swedish classification system. All patients answered questionnaire regarding life satisfaction. Logistic regression demonstrated significant differences in 6 of 10 specific dimensions of life satisfaction between the classification categories C and D (presence of arm symptoms) in a Swedish classification. Patients with whiplash-associated disorders grade II and neuropsychological symptoms seem to have a worse prognosis for spontaneous recovery than those without. A new Swedish classification system seems to be an important complement to the Quebec classification.
