Central cord syndrome

Central cord syndrome is the most common form of incomplete spinal cord injury characterized by impairment in the arms and hands and to a lesser extent in the legs. The brain's ability to send and receive signals to and from parts of the body below the site of injury is reduced but not entirely blocked.

The syndrome is associated with damage to the large nerve fibers that carry information directly from the cerebral cortex to the spinal cord. These nerves are particularly important for hand and arm function.

The overall amount and type of functional loss is dependent upon the severity of nerve damage. Central cord syndrome is usually the result of trauma that causes damage to the vertebrae in the neck or herniation of the vertebral discs. It also may develop in people over the age of 50 due to gradual weakening of the vertebrae and discs, which narrows the spinal column and may contribute to compression of the spinal cord when the neck is hyper-extended.

Common Symptoms

Symptoms may include paralysis or loss of fine control of movements in the arms and hands, with relatively less impairment of leg movements. Sensory loss below the site of the injury and loss of bladder control may also occur, as well as painful sensations such as tingling, burning or dull ache.


MRI is used to determine the degree of spinal cord compression and vertebral instability.


There is no cure for central cord syndrome although some people recover near-normal function. There is also no standard course of treatment, although drug therapy, surgery and rest are often part of the plan of care.

Vertebral instability due to acute traumatic injury or cervical disc herniation is often treated by surgery to prevent further damage to the spinal cord. Recent research indicates that earlier surgery may improve chances for recovery. Numerous recent studies suggest that surgery also can be beneficial in individuals with persistent compression of the spinal cord and ongoing neurological deterioration.

The prognosis for central cord syndrome varies, but most people whose syndrome is caused by trauma have some recovery of neurological function. Evaluation of abnormal signals on MRI images can help predict the likelihood that neurological recovery may occur naturally.

Patients who receive medical intervention soon after their injury often have good outcomes. Many people with the disorder recover substantial function after their initial injury, and the ability to walk is recovered in most cases, although some impairment may remain. Improvement occurs first in the legs, then the bladder, and may be seen in the arms. Hand function recovers last, if at all. Recovery is generally better in younger patients, compared to those over the age of 50.
