Abstrakt		Lumbar interneuronal networks have the capability to integrate brain command and afferent feedback signals to generate functional lower limb movements. Accidental spinal cord injury ean divide these structures from brain control. Under such conditions, applying tonic electrical stimulation to the lumbar cord can be an approach to mimic the missing tonic input normally provided by brain structures. From our studies it emerges that there are two different codes inducing the lumbar cord to respond with two different motor tasks. Stepping-like movements can be evoked when epidural stimulation is applied at 25-50 Hz. The lumbar spinal cord can also be induced to respond with a sustained lower limb extension. This fimctional reconfiguration is caused by lowering the stimulus frequency to 5-15 Hz without changing stimulation site or strength.
