Spinal Cord Injuries

UC San Diego Health offers a multidisciplinary program for restoring function to people with spinal cord injuries.

Unlike the peripheral nerves, cells in the spinal cord do not regenerate after an injury. Damage to the spinal cord can impact body function, strength and sensation, causing loss of feeling, weakness and paralysis.

Level of Spinal Cord Injury: Restoring Function

Spinal Cord Injury LevelsFunction We Restore at UC San Diego Health For Specific Spinal Injuries


Breathing using phrenic nerve pacer or ventilator.


Basic arm function (elbow flexion) using a nerve transfer.


Grasp and release function, and triceps function


More sophisticated grasp and release and finer hand movements.


Intrinsic balance to the hands.
 T2-T9Sensation to lower extremities via nerve transfer. Possibility of improving lower extremity function using spinal cord stimulation.*
 T10-T12Some hip movement and extension as well as sensation to proximal legs.
 L1-L2Hip extension with a nerve transfer (nerve transfer only used for those with some hip movement).
 L3-L4Improved walking with a nerve transfer (transfers only used in those who have some hip flexion and knee extension).
 L5-S1Ankle stability via a nerve or tendon transfer.

*NOTE: All patients with some movement in lower extremities may be considered as candidates for epidural stimulation to improve movement or reduce spasms.

Using epidural spinal cord stimulation, we can improve standing and walking in people who have cervical and thoracic level injury.

Spinal Cord Injury: Surgery & Treatment

Recovering even partial arm and hand function after a spinal cord injury can have an enormous impact on independence and quality of life. Our surgeons use the latest surgical techniques and treatments to improve level of functioning.

Surgical and nonsurgical treatment techniques we use:

  1. Nerve transfer: Nerves with the best control are transferred to the most important muscle groups to improve function in that limb.
  2. Tendon transfer: The most common procedure for restoring function. A tendon is moved from one point to another to improve joint function. Tendon transfers offer functional gains for an estimated 70 percent of tetraplegic patients.
  3. Selective peripheral neurotomy: Nerves are trimmed to reduce spasticity.
  4. Phrenic nerve stimulator: Patients dependent on a ventilator have the option of a surgically implanted phrenic nerve stimulator which frees them from ventilator dependency.
  5. Spinal cord stimulation: Electrodes placed in the space outside of the thick membrane that surrounds the spinal cord (the dura) to reduce pain and spasticity through nerve stimulation. Can also help with movement control.
