Possible mechanisms of neurologic recovery in spinal cord injury were postulated by Ditunno Jr. JF in 1987. The first window encompasses recovery from neurapraxia within 6 to 8 weeks. The second window covers the period from 2 to 8 months after the injury. Recovery during this period might be due to peripheral sprouting of intact nerves to denervated muscle and hypertrophy of functioning muscles. The third window of recovery happens usually beyond 8 to 12 months when axonal regeneration may play a role in further increases in strength.

On the basis of these possible mechanisms, we measured the neurological and functional recovery rate according to the periods of these possible mechanisms of motor recovery through 12 months following injury in 21 traumatic spinal cord injury patients.

The results were as follows:

1) Neurologically, the most rapid recovery was shown within 6 to 8 weeks after injury, during the phase of recovery from neurapraxia.

2) Most of functional recovery occured in the period between 2 month and 8 month of the compensatory phase.

3) Statistically significant correlation between motor and functional recovery was shown among the incomplete spinal cord injury group.

These data would be helpful in planning a timely appropriate rehabilitation program by understanding the time-course of neurologic recovery and prognostication of neurologic and functional recovery in the spinal-cord injured.
