A Research Of Local Vibration Syndrome On Worker's Attaching Vibration

The partial vibration is a legal occupational disease of our country. The area and work type of the incidence of partial vibration is more widespread. For example the chiseler, the oil saw worker, the grinding wheel polish worker, the concrete pounds the labor, riveter and so on all has arises. In order to understand the partial vibration gets sick arises the situation, the appraisal exposition time and the symptom relations, as well as the discussion partial vibration gets early diagnose, We to job seniority half year above the chiseler, the grinding wheel polish worker, the clear shovel worker, riveter the altogether 159 person of achievement contact vibration the group, the average job seniority in 10.5, and the choice did not contact the vibration the healthy male, the kind of work in a factory for the cook, the construction worker 48 people takes the comparison group, the average job seniority 8.3 years, carried on the contrast investigation. We choose the target includes: The partial symptom (hand hemp, hand pain, hand stiffen, hand swell, convulsion, trembles, more perspiration, hand cooling, cold allergy and holding thing is easy to fall), the whole body symptom (dizziness, insomnia, palpitation, tinnitus, hearing drops, feels weak, hypomnesia and dreamful), the distal circulation function, the distal nerve feeling function, the hand function. These indexes were study. The result discovers regarding contact vibration refers the group hand hemp, the hand pain, hand hemp, hand pain, hand stiffen, the convulsion, trembles, more perspiration, hand cooling, cold allergy and holding thing is easy to fall, these symptoms with contact vibration must in vain refers the group comparison difference is remarkable. contact vibration the group compares with the comparison group eliminates the multi-dreams not remarkable difference, dizziness, insomnia, palpitation, tinnitus, hearing drops, feels weak, hypomnesia and dreamful and so on has the extremely remarkable difference; The cold trial duplicate warm experimental discovery left hand or the right hand contact vibration group White Finger, contact vibration non-White Finger group is smaller than 5 minutes skins duplicate warm rate and the comparison group compares, obviously is lower than the comparison group, the cold trial duplicate warm time surpasses 30 minutes time. Left hands and the right hand contact vibration refers the group in vain with the comparison group, contact vibration must in vain refers with the comparison group all not remarkable difference. The armor wrinkles micro circulate examination center contact vibration the group finger exceptionally leads obviously to be higher than the comparison group; the distal nerve the function aspect, two resolutions experiments demonstration meets inspires the group compares the right hand middle finger, the ring finger with the comparison group, the left hand middle finger, the ring finger all has contact vibration, left hand ring finger relative danger is 13.403, right hand ring finger relative danger is 12.156, both hands ring finger approaches. The depth sense comparison demonstration meets inspires the group left hand the middle finger, the ring finger and the comparison group quite even not remarkable difference. Contact vibration the group right hand middle finger, ring finger and the comparison group quite even has contact vibration, relative dangerous separately is 1.484, 1.974, the right hand middle finger and the ring finger approaches. Simultaneously also discovers two resolutions, the depth sense and sense of pain three targetsmasculine genders rate along with contact vibration the dosage the increase advance; contact vibration the group White Finger, the hand hemp, the hand pain with contact vibration the dosage the relations is close, its masculine gender rate along with contact vibration the dosage the increase advances. The partial vibration mainly causes he distal nerve the function and he distal circulation function harm, this kind harms along with meets inspires the dosage the increase advances, also two harms is parallel. Contacts the partial vibration the labor had the multi-hands symptom and the neurasthenia syndrome. The partial vibration causes the hand function harms is various. According to this investigation result we think the hand hemp, the hand pain, t hand hemp, hand pain, hand stiffen, hand swell, convulsion, trembles, more perspiration, hand cooling, cold allergy. These symptoms all may take early diagnose. The hand pain, the hand hemp appears in particular comparatively early. Simultaneously because harms the degree along with contact vibration the dosage the increase aggravates. Therefore must control occurrence which the partial vibration gets sick, first must control worker contact vibration dosage.
