Recent advances indicate not only that the spinal cord has great potential
for locomotor recovery after lesion but also that locomotor training can op
timise this recovery through some form of 'learning'. Improvement of residu
al function can also be achieved through the use of various drugs and treat
ments such as spinal grafts. In spinal-cord-injured humans, a number of rec
ent studies have allowed an objective quantification of the improvement of
locomotion through various forms of training and stimulation.
