Novel assessment of the variation in cervical inter-vertebral motor control in a healthy pain-free population

Abstract Spinal control at intervertebral levels is dependent on interactions between the active, passive and neural control elements. However, this has never been quantifiable, and has therefore been outside the reach of clinical assessments and research. This study used fluoroscopy during repeated...
