This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.
Age: Recovery of a nerve after surgical repair depends mainly on the age of the patient. Young children can recover close-to-normal nerve function. In contrast, a patient over 60 years old with a cut nerve in the hand would expect to recover only protective sensation; that is, the ability to distinguish hot/cold or sharp/dull. [13]
Axon reinnervation is greatly affected by the pathway the regenerated nerve has chosen to grow along. The nerves' ability to properly function after damage is very dependent on successful reinnervation, which is why the effects of PMR are so relevant. The success of nerve reinnervation after different grafting attempts is a current research ...
A 40-year-old man whose legs are paralyzed is able to climb stairs, move over ramps and switch from standing to walking, thanks to implants in his brain and spinal cord that pair with external ...
Existing treatments aim to suppress the immune system to prevent further damage to nerve cells. A new study has developed a treatment that can help regenerate myelin with the potential to stop and ...
The length of the nerve and site of the injury influences the recovery time. To avoid tension during recovery (generally 10–14 days), minimizing movement of the nerve may reduce risk of further damage. [1] Regaining motor function is the intended result. Typical axon regrowth amounts to approximately 1 millimeter per day.
The damage to nerves supplying specific muscles may cause muscle twitching (fasciculations) in addition to the weakness. It is sometimes associated with weight loss. [2] Diabetes most commonly causes damage to the long nerves that supply the feet and lower legs, causing numbness, tingling and pain (diabetic polyneuropathy). Although these ...
