Neurapraxia
Neurapraxia
Neurapraxia (pronounced: noor-uh-PRAX-ee-uh) is a type of peripheral nerve injury. It is the mildest form of nerve injury, characterized by a temporary loss of motor and sensory function due to blockage of nerve conduction, usually following a minor injury.
Etymology
The term "neurapraxia" comes from the Greek words "neuron" (nerve) and "apraxia" (inaction). It was first used in medical literature by Seddon in 1943 to describe a type of nerve injury.
Symptoms
Symptoms of neurapraxia can include numbness, weakness, and loss of muscle function in the affected area. These symptoms are usually temporary and resolve with time.
Causes
Neurapraxia is often caused by compression or contusion of a nerve, such as in carpal tunnel syndrome or cubital tunnel syndrome. It can also occur as a result of ischemia or hypoxia.
Diagnosis
Diagnosis of neurapraxia is typically made based on the patient's symptoms and a physical examination. Electromyography (EMG) and nerve conduction studies may also be used.
Treatment
Treatment for neurapraxia usually involves rest and physical therapy. In some cases, surgery may be necessary to relieve pressure on the nerve.
