Head-trunk coordination in subjects with two motor neuron diseases during linear anterior-posterior translations

This paper looks into the influence of cerebellar disease and bilateral vestibular deficit along with visual inputs on head stabilization during a-p oscillatory linear acceleration at 0.60, 0.81, and 1.11 Hz. The results may infer that at these frequencies the system mechanism instead of voluntary movement, VCR and CCR dominates the head stabilization.
