Titre de la conférence : Comment le système nerveux central contrôle-t-il les muscles du tronc?

Résumé : 

Trunk muscles participate to multiple functions of the human body such as volitional movement, posture and respiration. Since trunk muscles are involved in volitional and automatic control, neural networks are probably located at different central nervous sytem (CNS) levels (e.g. spinal, brainstem, cortical) and through multiple descending pathways. In primates, trunk muscles are controlled mainly by neural networks located in the brainstem and projecting to the spinal cord through extrapyramidal tracts. Although studies on human cadavers confirm the presence of extrapyramidal tracts, assuming a similar function of the CNS remains problematic. In humans, evidence of extrapyramidal control over trunk muscles are scarce because of the challenge to test these networks. Transcranial magnetic stimulation has been used to assess the control of trunk muscles but this technique alone cannot be used to discriminate between the different CNS levels involved. This presentation will discuss state-of-the-art knowledge about the CNS control of trunk muscles in humans using multiple neurophysiological techniques such as TMS, stretch reflex and electrical vestibular stimulation and future perspectives. This knowledge may be used to test the influence of spinal pain on the control of the spine and its influence on the development of persistent pain.
