|Whiplash trauma is caused due to injury to the neck that occurs because of car accidents. It is very common in road accidents. In this there is sudden movement of the neck or hyperflexion or hyperextension of the neck. Due to this the neck muscles suffer injury and hence neck pain is caused. Two types of injury may be caused due to this- cervical hyperextension or rapid deceleration. In the former one person body is moved forward in the accident and the head lags behind and occurs in accidents when the person vehicle is hit from the behind. If the extension occur maximum then it is called flexion. In the latter injury the person body is thrown forward and may result in neurological damage. Whiplash trauma may result in severe headache and trauma, ear noises and dizziness may also occur in some cases. Medication is required if the nerve injury occurs.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
