If a section of an injured nerve is cut completely or damaged beyond repair. A surgeon can remove the damaged section and directly reconnect healthy nerve ends. This is known as nerve repair.
Schwann cells can help damaged nerves regenerate and restore function. On average, damaged nerves can grow back at a rate of about 1 inch per month or 1 millimeter per day. Surgery is needed if there is significant scar tissue or a gap between cut nerve ends.
When nerve damage occurs, the nerve can no longer carry messages. For example, if a sensory nerve is injured, you may not be able to feel a particular area of your skin. If a motor nerve is injured, you may have weakness or inability to perform certain movements.
The intervention protocol PLUS the home program is the most effective method of sensory reeducation and reestablishes the implication for sensory re-education within therapy sessions for peripheral nerve lacerations.
Treatment may involve observation, primary repair, nerve reconstruction with grafting, tendon transfers, nerve transfers, or a combination thereof depending on acuity, degree of injury, nerve quality, and mechanism of injury.
Sensory reeducation aids in the recovery of sensibility. In sensory stimulation pinching and tapping, brushing and icing are regularly used. Proprioception deficits can be improved using eg exercise balls, balance pads for WB activities, juggling balls for upper limbs, yoga, Tai-chi. Balance Deficits [edit | edit source]
The peripheral nervous system is a network of 43 pairs of motor and sensory nerves that connect the brain and spinal cord to the entire human body. When one of these nerves suffers injury or trauma, surgical treatment may be needed.
Like electrical cords, 43 pairs of peripheral nerves extend from the spinal cord and enable movement, motor coordination and sensation throughout the body. The pain, tingling, numbness and other discomforts of peripheral nerve disorders can often be treated successfully with physical therapy and other nonsurgical methods.
Distal axon degeneration (Wallerian degeneration) involves motor and sensory fiber deterioration immediately within 24-36 hours. Paralysis and sensory loss develop acutely, but nerve conduction of the distal segment remains intact until the distal segment is consumed by Wallerian degeneration.
Nerve repair surgery aims to restore function and sensation that was partially or completely lost due to nerve damage. For example, if a nerve injury caused paralysis in the arm, the surgery aims to return movement and sensation to the arm.
