Repetitive Strain Injury (RSI)

Although devalued, musculoskeletal injuries, particularly Repetitive Strain (RSI) grow annually and reach an alarming proportion epidemiology.The RSI is already one of the lesions that are among the major causes of absolute incapacity to work.

The notion that certain professions can induce disease is not new. Indeed, there are already more than 300 years have been known to work, which is fundamental in the life of mankind, when conducted in poor condition is harmful and causes ill health and inactivity.

RSIs are caused by the performance of an activity repeatedly and continuously. All work carried out daily, using the same movements have a strong likelihood of onset of RSI. In practice present as sudden events, usually affecting the upper limbs, hands, wrists, arms, forearms, shoulder and cervical spine, and are characterized by the diagnosis with different names, carpal tunnel syndrome, tendonitis, tenosinovites, bursitis , trigger finger, epicondylitis, etc..

The RSI is an injury that directly relates to the activity of the person affected, and in some cases can be understood as an occupational disease, which occurs whenever there is inconsistency between the requirements of physical activity or task and the physical capacity of the human body to accomplish.

There are some risk factors that contribute to the installation of this injury, repetitive motions, incorrect posture, lifting weights, etc.. This is because the human body is not prepared to perform a repetitive muscle activity, and continuing need for long periods (eg computers and typing, typing intensive is one of the most common causes of the incidence of RSI).

These lesions settle slowly and often go unnoticed over a lifetime of work but when there are perceived as a serious compromise of the affected area.

What are the symptoms of RSI?
The RSI are characterized by symptoms such as:

  • Pain, most often located, but that can radiate to other areas;
  • Numbness or "tingling" in the affected area or nearby areas;
  • Feeling of heaviness;
  • Fatigue or discomfort located;
  • Sense of loss or even total loss of strength.

In most cases, the symptoms of RSI emerge gradually become worse at the end of the workday or during peak production and soothe with pauses or rest and vacation.

If exposure to risk factors continues, the symptoms, which initially are intermittent, gradually become persistent, lasting many times at night, remaining even during periods of rest and not only interferes with the ability to work, but also with the common activities of day-to-day.

Initially the prognosis of RSI is favorable, with rapid recovery and short-lived. Treatment sessions are for solving biological problems, but also for the information / postural education.

How to prevent the onset or recurrence of RSI?
- For every 25 minutes in an occupation involving the use of repetitive movements, precise and continuous must pause 5;
