Abstract

Objectives: Prolonged exposures to hand arm vibration among hand held machine user revealed caused development of vibration induce disability. The present study was to determine the effect of hand transmitted vibration by using hand numerical scoring and hand grip strength force assessment. Methods: A case study using adopted HAVS questionnaire and physical observation was investigated to a subject of 204 male workers from grass maintenance contractor. Two health effect assessments was done in this work comprises of severity stage of vascular and sensori-neural for both hand as well as the hand grip strength force. The correlation of workers experience between tow health effects was analyzed. Results: More than 90% of worker has been experience at risk hand grip stage for the both hand. Above stage 2 there were 172 workers (84.3%) with vascular disorder in the left hand while 163 workers (79.9%) with vascular disorder in the right hand. As for sensori-neural disorder, numbers of workers above stage 2 were 169 (82.8%) and 162 (79.4%) respectively. Conclusion: The results suggest that chronic health surveillance for hand arm vibration is under diagnosed in agriculture sector.
