Computer arm or rsi also mentally conditioned

Scientists can be able to prove that RSI is not only caused by repeated movements, but above all by stress at work and with colleagues and supervisors

Repetitive Strain Injury (RSI), also called computer arm, is in people working on the screen, a widespread chronic disease in the arm hand area. RSI is caused by fast, short and often repeated movements. They drove to cracks in the stressed muscles and symptoms such as pain and numbness feathering, power loss, sensitivity loss, muscle vapor and even paralyzes. But according to a new study, RSI is not how to previously believe in the nature of repeated movements, but also has mental causes.

As a rule, the psyche plays in diseases. With RSI – "Damages by repeated load" – but seemed to be relatively unique. So from 80000 keyboard strikes there is a risk of illness, which is the gross, the faster one works. Scientists from the Department of Epidemiology Chronic Diseases of the University of Manchester, however, ame that the pain associated with RSI are not only associated with repeated movements but with different factors, including high psychological stress and lack of support by colleagues.

For your study "Role of Mechanical and Psychosocial Factors in The Onset of Forearm Pain: Prospective Population Based Study", published in BMJ (321: 676, 16. September), questionnaires of more than 1200 people between the ages of 18 and 65 were evaluated, which were collected over the course of two years. The sample should be representative of the British population. The respondents should specify the places in the drawing of a human body where they perceived at least once during the last month. In addition, information was collected via the professional career. Those who reported from pain in the foregs had to be made a further questionnaire.

8.3 percent of people from the sample had jokes in the forearm. There were no significant differences between manners and women. Of these 105 people, in turn, 67 percent also reported shoulder pain, 65 percent of smuck pain and 45 percent of chronic pain in many body points. Normally, with RSI related pain does not occur isolated. A "easy" Higher risk to develop pain in the forearm, people are exposed to the "half or the coarse part of the time" During work things lifting, wearing or pulling things. The highest risk arises with repeated movements of the arms and wrists.

At the same time, however, the people who have pain in the forearm, conditions of mental stress in the workplace. Mainly, dissatisfaction with the support of the supervisor or colleague is responsible. Who is the practice that he can hardly make their own decisions at work, has a doubled risk for the training of pain, while in those who complain about too much hectic, boredom or monotony, did not find any significant differences.

The scientists from these results are the consequence that terms such as RSI are too simple to capture the varied psychosomatic causes of pains in the forearm area. Gary Macfalane, who led the investigation, says that you do not really know what causes pain: "Repeated movements play a role, but there are too many other important factors such as work requirements and support in the work. Also, how the individuals perceive their work can be important." Employers who want to reduce the risk of RSI in their employees should not only take into account MacFalane’s body work and mechanical stress, but also the work environment and organization.

Diseases of the link – Including shoulders, neck wrist and elbow – through static repetitive movements at work are very common in all EU countries. After the survey of the European Agency for Safety and Health in the workplace, take even. In Luxembourg are 30 percent of all recognized occupational diseases in connection with RSI. Allegedly, RSI is responsible for 60 percent of all workfalls in the USA, in the UK, more than 200,000 people are suffering from RSI.
