Musculoskeletal disorders (MSDs) are the minor physical disabilities that consist of a group of painful disorders of muscles, tendons, bones and nerves. The severity of the MSD can vary according to age. They are extremely common, and the risk increases with age. Pain and discomfort may interfere with everyday activities. Some of the examples are: Carpal tunnel syndrome, thoracic outlet syndrome, tendonitis, and tension neck syndrome are examples.
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.
