Sponataneous recovery after SCI
Almost all people who sustain a SCI show some recovery of motor function below the initial spinal injury level. The spontaneous recovery of motor function in those with motor-complete SCI is fairly limited. But recovery in incomplete SCI patients is both more substantial and highly variable. With motor complete lesions the majority of functional return is within the zone of partial preservation.
Most recovery occurs in the first 3 months. But a small amount can occur for up to18 months or longer. Some sensory recovery occurs after SCI, on roughly the same time course as motor recovery.
