Repetitive strain disorder (RSD), also known as repetitive strain injury (RSI), is a condition that affects the muscles, tendons, and nerves of the body, usually in the upper extremities. It is primarily caused by repetitive and excessive use of certain muscles and tendons, often due to repetitive motions or activities performed over an extended period.
The repetitive nature of the movement puts strain on the affected tissues, leading to inflammation, pain, and dysfunction. RSD can manifest in various forms, including carpal tunnel syndrome, tennis elbow, golfer's elbow, and tendinitis, among others. It commonly affects individuals who engage in repetitive activities like typing on a keyboard, using a mouse, playing musical instruments, performing assembly line work, or participating in sports with repeated motions.
Symptoms of repetitive strain disorder may include pain, stiffness, weakness, numbness, tingling, and reduced range of motion in the affected areas. The discomfort may start gradually and worsen over time. If left untreated or ignored, RSD can significantly impact daily activities and cause long-term complications.
Preventive measures for repetitive strain disorder involve maintaining proper ergonomics, practicing frequent breaks and stretching during repetitive tasks or prolonged periods of activity, and using appropriate equipment and tools. Treatment typically involves rest, activity modification, physiotherapy, pain management techniques, and, in severe cases, surgery. Timely intervention and adopting ergonomic practices can significantly reduce the risk of developing or exacerbating repetitive strain disorder.
