Carpal tunnel syndrome is a neurological disorder that occurs when the median nerve, which runs from your forearm into the hand, becomes squeezed. What happens to your body when you have carpal ...
The development of carpal tunnel syndrome was of particular interest for other idiopathic tardy nerve palsies. Carpal tunnel served as a model for how nerves could be squeezed by narrow anatomic compartments and soon other tunnel syndromes were conceptualized, such as cubital tunnel syndrome, and tarsal tunnel syndrome.

Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.
In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand. [1]
Carpal tunnel surgery is usually considered after other treatment options have failed, Melamed says. Other, less invasive treatments, like splinting and steroid injections, are typically tried first.
Carpal tunnel syndrome presents in each individual to different extents. Measurements of nerve conduction velocity are critical to determining the degree of severity. [14] [15] These levels of severity are categorized as: [12] [13] Mild CTS: Prolonged sensory latencies, very slight decrease in conduction velocity. No suspected axonal degeneration.
Peripheral nerve studies have shown that even a 0.5 °C increase in body temperature can slow or block the conduction of nerve impulses in demyelinated nerves. With greater levels of demyelination, a smaller increase in temperature is needed to slow down the nerve impulse conduction. [ 8 ]
This results in the symptoms of carpal tunnel syndrome. [3] Symptoms of carpal tunnel syndrome include tingling sensations and muscle weakness in the palm and lateral side of the hand and palm. It is possible that the syndrome may extend and radiate up the nerve causing pain to the arm and shoulder. [4] Carpal tunnel syndrome may be treated ...
