FIRST-PERSON SHOOTER CARPAL TUNNEL SYNDROME (FPS CTS) A pathophysiology that affects millions of gamers that engage in first-person shooting activities, FPS CTS is caused mainly by repetitive motions, most famously from long hours of computer keyboard use. It results in a compression of the carpal tunnel, permanent nerve damage, and weakness of palmar abduction. Patients with CTS experience burning sensations in the thumb and fingers, particularly the index, middle fingers, and radial half of the ring fingers which are innervated by the median nerve. Also reported is sharp pain in the arm and shoulder. If not treated on time, this condition can degenerate quickly. Tumors such as a ganglion or a lipoma protrude into the carpal tunnel, leading to numbness and atrophy in the wrist. Due to the severity of this condition, amputation is currently the only effective therapy. — 13 Measurements of carpal tunnel pressure (CTP) under conditions typically observed among computer users showed pressure values below levels considered harmful.
