Behavior of the Upper Cervical Spine in Rugby Players

Not Applicable

Terminated

• Conditions: Cervical Spine Destabilization
• Interventions: Other: Destabilization of the upper cervical spine by Cervistab

• Registration Number: NCT03712514
• Lead Sponsor: University Hospital, Montpellier

Brief Summary

Rugby players are often exposed to destabilisation of the upper cervical spine.This kind of trauma may lead to dramatic injuries, due to lesion of spinal cord.

CerviStab© is a device which evaluate the bio-mechanical and neuromuscular behavior of the upper cervical spine in rugby situation.

The aim of this study, is to evaluate the dynamic stabilization of the upper cervical spine in reaction to unexpected impact.
