Neuropathy - distal median nerve
Pain in the wrist or hand that wakes you up at night
May be severe Pain may be felt in other areas, for example in the upper arm (this is called referred pain)
Sensation changes in the thumb and pointer (index), middle, and part of the ring fingers, such as:
Weakness of the hand that causes you to:
Drop things Have difficulty grasping objects
Signs and tests
Your doctor will examine your wrist and ask questions about your medical history. The examination may show decreased sensation in the thumb side of the hand. This is called the "radial" side. There may be weakness of the thumb and difficulty using it to pinch.
Tests that reveal distal median nerve dysfunction may include:
Nerve conduction tests
Tests are ...
Definition Radial nerve dysfunction is a problem with the radial nerve. Damage to the radial nerve leads to problems with movement or sensation of the back of the arm (triceps), forearm, or hand. Alternative Names Neuropathy - radial nerve; Radial nerve palsy; Mononeuropathy Causes, incidence, and risk factors Radial neuropathy occurs when there is damage to the radial nerve, which travels down the arm and controls movement of the triceps muscle at the back of the upper arm. It also controls the ability to bend the wrist backward and helps with the movement and sensation of the wrist and hand. Mononeuropathy means a single nerve is damaged. With mononeuropathy, usually the nerve damage is caused locally. However, body-wide disorders may damage just one nerve. Causes are: Injury
"Crutch palsy," caused by improper use of crutches Fracture of the humerus (upper arm bone) Long-term or repeated constriction of the wrist (for example, from wearing a tight watch strap) Pressure caused by hanging the ...
Definition Tibial nerve dysfunction is a loss of movement or sensation in the lower leg, caused by damage to the tibial nerve. Alternative Names Neuropathy - tibial nerve Causes, incidence, and risk factors Tibial nerve dysfunction is a form of peripheral neuropathy . It occurs when there is damage to the tibial nerve, one of the branches of the sciatic nerve of the leg. The tibial nerve supplies movement and sensation to the calf and foot muscles. Dysfunction of a single nerve group, such as the tibial nerve, is called mononeuropathy . Mononeuropathy implies a local cause of the nerve damage, although occasionally systemic disorders may cause isolated nerve damage (such as occurs with mononeuritis multiplex ). The usual causes are direct trauma, prolonged pressure on the nerve, and compression of the nerve from nearby body structures. Entrapment involves pressure on the nerve where it passes through a narrow structure. The damage may include destruction of the myelin sheath of the nerve (the in...
