Comparison of visual and ultrasound based techniques to measure head repositioning in healthy and neck-pain subjects

The neural control of the headeneck system depends on the convergence of the cues provided by the proprioceptive, vestibular and visual paths (Lakie and Loram, 2006). The vestibular and proprioceptive systems interact (Karnath et al., 1994), and oculo-cervical coupling has been identified (Andre-Deshays et al., 1988).
