Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Carpal tunnel syndrome is a neurological disorder that occurs when the median nerve, which runs from your forearm into the hand, becomes squeezed.
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 ]
For example, Keir et al. suggest breaking up the repetitive action of using a computer mouse with other tasks because mouse use was shown to increase carpal tunnel pressure. This study also suggests minimizing wrist extension through appropriate body posture at the workstation that may help to reduce carpal tunnel pressure. [30]
In addition, they may cause the syncope by lowering the blood pressure and heart rate. [23] [24] Medications which may be effective include: CNS stimulants [25] fludrocortisone, midodrine, SSRIs [26] such as paroxetine or sertraline, disopyramide, and, in health-care settings where a syncope is anticipated, atropine or epinephrine (adrenaline ...
[11] [12] Theoretically, delivering electricity through the body may affect systems in the body that depend on electrical signals, such as the heart and brain. [11] Patients are encouraged to tell the examiner before the study if they have such devices, but their existence in the patient does not prevent them from having the study performed. [12]
