(SCI) usually leads to permanent motor and sensory deficits. This is due to
a lack of any functionally significant regeneration of severed nerve fibre
s within the adult central nervous system (CNS). The last 10-15 years have
witnessed remarkable progress in understanding the cellular and molecular m
echanisms which contribute to the failure of CNS axon regeneration. In this
context, several substances with growth promoting or growth inhibiting pro
perties have been identified. This has led to the development of a number o
f experimental intervention strategies, many of which have promoted a subst
antial degree of improved motor function. This knowledge has already result
ed in the planning of clinical trials. Nonetheless, there are still substan
tial gaps in the detailed understanding of how such intervention strategies
should be applied to meet the individual circumstances of patients with ac
ute or chronic SCI.
