Unauthorized commercial reproduction of this slide is prohibited Supplemental PowerPoint Slides Key points Neck pain is a common condition causing absence from work and disability, and with a considerable impact on healthcare systems. Neck training programs usually consist of coordination, strengthening, and endurance exercises; however, it is unclear which type of training is the most effective. No studies have previously investigated the neural effect of neck training and the possible differential effect of specific neck training versus coordination training on corticomotor control. Our results showed that specific and load-dependent specific neck training significantly increased and sustained motor evoked potentials for up to 7 days. This sustained facilitation of the motor neurons may prove valuable in the process of improving and developing more effective training programs for neck pain.
