Our peripheral nervous system is an extensive network of nerves that integrates all body parts to the brain and the spinal cord. Since these peripheral nerves are delicate, they are easily susceptible to injury. Trauma to these nerves via medical, surgical or physical damage results in peripheral nerve injuries (PNIs), which can cause loss of sensory and motor functions leading to long-term disabilities and reduced quality of life.
The symptoms vary depending on the severity of the injury, the type of injury and the nerve involved. These include numbness, lack of sensations, impaired muscle movement and paralysis in the affected region.
Recovering from a PNI takes time, depending on the extent and type of damage. While surgical intervention is the primary management strategy, experts are developing non-surgical methods so that people can lead a better quality of life.
