The Self Defense Test Ship (SDTS) is an asset of the US Navy. It is a refurbished ship that is in some cases operated by remote control; that capability is designed to support self-defense engineering, testing, and evaluation. [citation needed] When uncrewed, it can avoid the safety constraints and other problems associated with crewed ships.
Although surgical intervention for CTS by releasing the flexor retinaculum to alleviate median nerve compression is often effective, surgery is primarily recommended to relieve severe or long-term, chronic symptoms. Even with surgery, research has suggested that pain still exists in up to 38% of patients who receive surgery. [10]
Durkan's test, carpal compression test, or applying firm pressure to the palm over the nerve for up to 30 seconds to elicit paresthesia. [41] [42] Hand elevation test The hand elevation test is performed by lifting both hands above the head. Paresthesia in the median nerve distribution within 2 minutes is considered positive.
Compression of the median nerve in the region of the elbow or proximal part of the forearm can cause pain and/or numbness in the distribution of the distal median nerve, and weakness of the muscles innervated by the anterior interosseous nerve: the flexor pollicis longus ("FPL"), the flexor digitorum profundus of the index finger ("FDP IF"), and the pronator quadratus ("PQ").
The recurrent branch of the median nerve is also colloquially called the "Million Dollar Nerve", because injury to this nerve during carpal tunnel surgery can lead to a million dollar lawsuit. Injury to this nerve can lead to loss of function of the thumb. Such injury can happen if the flexor retinaculum is transected too radially. The ...
The procedure is used as a treatment for carpal tunnel syndrome and according to the American Academy of Orthopaedic Surgeons (AAOS) treatment guidelines, early surgery is an option when there is clinical evidence of median nerve denervation or the patient elects to proceed directly to surgical treatment.

Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord). [1] [2]
