One cause of ganglion cysts is Repetitive Motion
What causes Repetitive Motion Disorders?
Causes: Repetitive motion disorders (RMDs) are a family of muscular conditions that result from repeated motions. RMDs include carpal tunnel syndrome, bursitis, tendonitis, epicondylitis, ganglion cyst, tenosynovitis, and trigger finger.
RMDs are caused by too many uninterrupted repetitions of an activity or motion, unnatural or awkward motions such as twisting the arm or wrist, overexertion, incorrect posture, or muscle fatigue. RMDs occur most commonly in the hands, wrists, elbows, and shoulders, but can also happen in the neck, back, hips, knees, feet, legs, and ankles. The disorders are characterized by pain, tingling, numbness, visible swelling or redness of the affected area, and the loss of flexibility and strength.
Some people may have no visible sign of injury, although they may find it hard to perform easy tasks. Over time, RMDs can cause temporary or permanent damage to the soft tissues in the body such as the muscles, nerves, tendons, and ligaments – and compression of nerves or tissue. Generally, RMDs affect individuals who perform repetitive tasks such as assembly line work, meat-packing, sewing, playing musical instruments, and computer work.
