Can you tell me how can excessive exposure to electronics lead to orthopedic disorders?

Excessive use of the: Hands, wrists, elbows results in overuse conditions like tendonitis mainly in fingers, wrists, elbows; carpal tunnel syndromes, cubital t syndromes (where the 2 main nerves to the fingers get trapped under tight ligaments, at the wrist or elbow); tennis/golfer's elbows (epicondylitis at outer or inner aspect of the elbow). Using an ergonomically styled keyboard, desks, seats all help greatly.

Not from the expos--: -ure but due to typing on a key board or using a mouse. Keyboard can lead to carpal tunnel or tendinitis, the mouse is more localized to the index finger.
