What happens when a nerve is stretched?
Neurapraxia can occur when a nerve has been stretched or compressed beyond its normal range. The damage doesn’t actually happen to the nerve itself, but to the surrounding myelin sheath. Myelin acts as insulation around a nerve and is necessary for the nerve to function properly.
What are the different types of nerve injuries?
Other nerve injury categories include: 1 Axonotemesis: The cable-like filaments (axons) in the nerve, which are surrounded by myelin, have been damaged. With treatment, a full recovery may be possible. 2 Neurotemesis: The entire nerve has been severed. Full recovery isn’t likely unless surgery can connect the nerve back together. 3 Avulsion: The nerve has been completely separated from the spinal cord. There is no chance for repair or recovery.

What are the symptoms of neurapraxia?
Common symptoms of neurapraxia are disturbances in sensation, weakness of muscle, vasomotor and sudomotor paralysis in the region of the affected nerve or nerves, and abnormal sensitivity of the nerve at the point of injury. It has been observed that subjective sensory symptoms include numbness, tingling, and burning sensations at the site of the injury. Objective sensory symptoms are generally minimal in regards to touch, pain, heat, and cold. In cases of motor neuron neurapraxia, symptoms consist of flaccid paralysis of the muscles innervated by the injured nerve or nerves.

Overview
Neurapraxia is a disorder of the peripheral nervous system in which there is a temporary loss of motor and sensory function due to blockage of nerve conduction, usually lasting an average of six to eight weeks before full recovery. Neurapraxia is derived from the word apraxia, meaning “loss or impairment of the ability to execute complex coordinated movements without muscular or sensory impairment”.
Signs and symptoms
A variety of nerve types can be subjected to neurapraxia and therefore symptoms of the injury range in degree and intensity. Common symptoms of neurapraxia are disturbances in sensation, weakness of muscle, vasomotor and sudomotor paralysis in the region of the affected nerve or nerves, and abnormal sensitivity of the nerve at the point of injury. It has been observed that subjective sensory symptoms include numbness, tingling, and burning sensations at the site of t…
Causes
The cause of neurapraxia is a neural lesion which causes a temporary block of nerve conduction without transection of the axon. A conduction block is classified as a 40% reduction in action potential amplitude over a short distance on the nerve, or a 50% reduction for a longer distance on the nerve. In neurapraxia, stimulation to the injured nerve results in a greater reduction in the action potential amplitude on the proximal site of the injury as opposed to the distal site.
Anatomy
Neurapraxia occurs in the peripheral nervous system typically in the ulnar, median, and radial nerves of the upper body and in the sciatic and peroneal nerves of the lower body. Peripheral nerves are myelinated, relatively large, spatially complex cells whose size and connectivity typically make them more susceptible to damage and compromise their capacity to self-repair, although this is not the case in neurapraxia. Microscopic evidence has shown that there is damage to the …
Diagnosis
There are three distinct classifications and degrees of nerve injury:
• Neurotmesis is the most serious degree of nerve injury. It involves the disruption of the nerve and the nerve sheath.
• Axonotmesis occurs when the majority of the supporting structures of the nerve are preserved, but disruption of the nerve fibers is still observed. Wallerian degeneration often occurs in the near the proximity of the injury site.
Treatment and recovery
The entire nerve is involved in the response to traumatic injuries. The outcome of nerve repair is dependent on the degree of the nerve injury and the circumstances at the site of injury. Since neurapraxia is the least serious form of peripheral nerve injury, recovery and treatment are not extensive. Once the cause of neurapraxia is eliminated, recovery of the lesions in the nerve occurs within a short time span.
Prognosis
In cases of neurapraxia, the function of the nerves are temporarily impaired. However, the prognosis for recovery from neurapraxia is efficient and quick. Recovery begins within two to three weeks after the injury occurs, and it is complete within six to eight weeks. There are instances when function is not completely restored until four months after the instance of injury. The recovery period of neurapraxia is not an entirely ordered process, but the recovery is always …
Epidemiology
Neurapraxia is most commonly observed in athletes involved in collision sports, such as American football.
