Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation (inflammation mediated by nerve cells), nociceptive sensitisation (which causes extreme sensitivity or allodynia), vasomotor dysfunction (blood flow problems which cause swelling and discolouration) and maladaptive neuroplasticity ...
Tarsal tunnel syndrome. The mucous sheaths of the tendons around the ankle. Medial aspect. Tarsal tunnel syndrome ( TTS) is a nerve compression syndrome or nerve entrapment syndrome causing a painful foot condition in which the tibial nerve is entrapped as it travels through the tarsal tunnel. [ 1][ 2] The tarsal tunnel is found along the inner ...
Untreated carpal tunnel syndrome, showing shrinkage (atrophy) of the muscles at the base of the thumb. 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 is an idiopathic syndrome but there are ...
Phalen maneuver. Transverse section across the wrist and digits. (The median nerve is the yellow dot near the center. The carpal tunnel is not labeled, but the circular structure surrounding the median nerve is visible.) Phalen's maneuver is a diagnostic test for carpal tunnel syndrome [ 1] by an American orthopedist named George S. Phalen.
Specialty. Neurology. Chronic inflammatory demyelinating polyneuropathy ( CIDP) is an acquired autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensory function in the legs and arms. [ 1] The disorder is sometimes called chronic relapsing polyneuropathy ( CRP) or chronic inflammatory ...
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). Its symptoms include pain, tingling ...
Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [ 2][ 5] It is a specific case of deep gluteal syndrome. [ 6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
Restricting wrist motion eliminates the repetitive movement and tension overload in the carpal tunnel. This gives the tendon sheaths a chance to heal, reducing swelling, which then may decrease the pressure on the median nerve. Splints also aim to keep the wrist at a certain angle to decrease pressure within the carpal tunnel.
