Neck muscle vibration and spatial orientation during stepping in place in humans
TL;DR: The results confirm and extend the notion that the neck proprioceptive input plays a major role in body orientation during locomotion and suggest that the asymmetric neck input would seem to modify the egocentric body-centered coordinate system.

Abstract: Unilateral long-lasting vibration was applied to the sternomastoid muscle to assess the influence of asymmetric neck proprioceptive input on body orientation during stepping-in-place. Blindfolded s...

Sensorimotor disturbances in neck disorders affecting postural stability, head and eye movement control
TL;DR: It is advocated that assessment and management of abnormal cervical somatosensory input and sensorimotor control in neck pain patients is as important as considering lower limb proprioceptive retraining following an ankle or knee injury.

Direction-Dependent Control of Balance During Walking and Standing
Shawn M. O’Connor,Arthur D. Kuo +1 more
TL;DR: Whether healthy humans exhibit direction-dependent control in the fore-aft direction is tested, and step variability is found to be nearly 10 times more sensitive to ML than to AP perturbations, as quantified by the increase in root-mean-square step variability per unit change in perturbation amplitude.

Sensorimotor Function and Dizziness in Neck Pain: Implications for Assessment and Management
TL;DR: The scope of this paper is to highlight the sensorimotor deficits that can arise from altered cervical afferent input, and review the most relevant theoretical and practical knowledge on this matter and implications for clinical assessment and management.

Cognition in action: imaging brain/body dynamics in mobile humans
Klaus Gramann,Joseph T. Gwin,Daniel P. Ferris,Kelvin S. Oie,Tzyy-Ping Jung,Chin-Teng Lin,Lun-De Liao,Scott Makeig +7 more
TL;DR: Examples of the tight coupling between human physical structure with cognitive processing and the role of supraspinal activity during control of human stance and locomotion are given.
Human walking along a curved path. I. Body trajectory, segment orientation and the effect of vision.
TL;DR: The changes in the amplitude of head, trunk and feet movements proved to be well related to the kinematics of the steering body, and constituted a sort of basic library of motor synergies.

TL;DR: It is concluded that fatigue signals originating from the muscle and traveling through capsaicin-sensitive fibers are able to diminish the proprioceptive input by a central presynaptic influence.

Diagnostic value of vibration-induced nystagmus obtained by combined vibratory stimulation applied to the neck muscles and skull of 300 vertiginous patients.
TL;DR: On subjects with unilateral vestibular dysfunction, the application of a vibratory stimulation to the two mastoids and the vertex, and to the right and left dorsal neck muscles produces a nystagmus directed towards the good ear in 85% of patients.

Effects of caloric vestibular stimulation on head and trunk movements during walking.
TL;DR: It is suggested that vestibular sensory information, probably via the horizontal semicircular canals, contributes predominantly to the regulation of dynamic head and trunk movements in the M/L direction.

Fusimotor system in muscle fatigue.
Ljubisavljević M,Anastasijević R +1 more
TL;DR: It remains to be assessed whether such a reflex increase in fusimotor activity develops during fatiguing muscle contraction in decerebrate and/or spinal cats and plays a role in muscle fatigue in intact animals and/ or humans.

Cervical receptors and the direction of body sway.
TL;DR: It appears that cervical proprioceptive input to the central vestibular system is responsible for the effect observed, and a systematic translation of the direction of body sway that was associated in a consistent manner with the unilateral deficit is observed.
