Repetitive Strain Injury

112

RSI is the acronym for “Repetitive Strain Injury” and represents a group of disorders of the musculoskeletal system. WMSD stands for “Work-Related Musculoskeletal Disorders”.

Is RSI a disease? 

No, RSI does not correspond to a disease or illness. RSI is the acronym for “Repetitive Strain Injury” and represents a group of disorders of the musculoskeletal system. There are several conditions that present different clinical manifestations and vary in intensity.

Why the acronym DORT? 

It represents the acronym for “Work-Related Musculoskeletal Disorders” and was introduced to replace the acronym RSI, particularly for two reasons: first because most workers with symptoms in the musculoskeletal system do not show evidence of injury to any structure; the other reason is that in addition to repetitive effort (dynamic overload), other types of overload at work can be harmful to the worker such as static overload (use of muscle contraction for prolonged periods to maintain posture); excessive force used to perform tasks; use of instruments that transmit excessive vibration; works performed with inadequate postures.

What are the most common disorders? 

The most frequent occupational musculoskeletal disorders are tendonitis (particularly of the shoulder, elbow and wrist), low back pain (pain in the lower back) and myalgia (muscle pain) in different parts of the body.

Does the worker in pain or other symptom have RSI or WMSD? 

Not necessarily. Symptoms such as pain, numbness, tingling, pins and needles, decreased strength, feeling of heaviness or tiredness in the limbs, swelling, difficulty in moving, discomfort, among others, may be due to various conditions not related to biomechanical overloads in the environment of work. Many rheumatic, immunological, hormonal, metabolic, orthopedic, neurological or infectious disorders can be responsible for symptoms that simulate a work-related musculoskeletal disorder. Therefore, it is extremely important to seek medical attention for an accurate diagnosis and an adequate therapeutic strategy.
