Changes of the vibratory sensation threshold in workers using vibrating tools.
Vibratory sensation thresholds of ten fingertips of each person were measured by each of the three frequencies in groups using three kinds of vibrating tools and the control groups. The subject groups were using leg-drill (n=37), chipping-hammer (n=25) and chain-saw (n=19). The control groups were engaged in desk work or outdoor work in a bureau of forest management (n=24), a local forest offic...
متن کاملRaynaud's phenomenon in workers with vibratory tools.
The relationship between the prolonged use of pneumatic powered tools and the development of Raynaud's phenomenon was first described by Loriga (1911), and subsequently by Hunter, McLaughlin, and Perry (1945), and by Lindqvist and Flemberg (1945). This association with high frequency vibratory tools was later extended to other industrial processes. Telford, McCann, and MacCormack (1945) and Aga...
متن کاملA study on the effects of countermeasures for vibrating tool workers using an impact wrench.
The aims of this study were (1) to measure frequency-weighted vibration acceleration and (2) to study the effects of introducing a vibration-proof impact wrench on VWF in workers. The subject pool was 383 male workers who were regularly using an impact wrench and taking special medical examinations for vibration syndrome in a factory from 1982 to 1999. The prevalence of workers with VWF increas...
متن کاملDelayed recovery of nerve conduction and vibratory sensibility after ischaemic block in patients with diabetes mellitus.
OBJECTIVES To determine if the recovery of nerve function after ischaemic block is impaired in patients with diabetes mellitus relative to healthy controls. METHODS Median nerve impulse conduction and vibratory thresholds in the same innervation territory were studied in patients with diabetes mellitus (n = 16) and age matched controls (n = 10) during and after 30 minutes of cuffing of the fo...
متن کاملTemporary threshold shift of vibratory sensation induced by a vibrating handle and its gripping force.
OBJECTIVE This study examines the effect of the force with which a vibrating handle is gripped on the temporary threshold shift of vibratory sensation (TTSv) induced by hand-arm vibration. METHODS Six healthy subjects gripped a handle vibrating with a 1.3 octave-band vibration, with a central frequency of 200 Hz and an intensity of 39.2 m/s2. Exposure was for 1 min and 10 min, respectively. G...
