Neck proprioceptive input, as elicited by muscle vibration, can produce destabilizing effects on stance and locomotion. Neck muscle fatigue produces destabilizing effects on stance, too. Our aim was to assess whether neck muscle fatigue can also perturb the orientation in space during a walking task. Direction and amplitude of the path covered during stepping in place were measured in 10 blindf...

Neck muscle vibration is known to influence body orientation and posture during locomotion and stance in normal subjects. To verify the hypothesis that neck proprioceptive input can be misinterpreted in patients with cervical dystonia (CD), lateral continuous vibration was applied to the sternocleidomastoid muscle during both stepping-in-place and quiet stance, with eyes closed. The orienting r...

[Purpose] This study was performed to investigate the changes in the body balance index when spiral taping is applied to the neck and ankle. The findings are expected to serve as evidence of the usefulness of taping the neck instead of the ankle when ankle taping is not feasible in clinical practice. [Subjects and Methods] Twenty healthy male students at A university were enrolled in this study...

Position-vestibular-pause (PVP) neurons and vestibular only (VO) neurons are thought to mediate the vestibulo-ocular and vestibulo-collic reflexes, respectively. Both neuron classes are much less sensitive to head motion during active gaze shifts than during passive whole-body rotation (pWBR).1–5 The mechanism that underlies this differential processing of vestibular information is not known. N...

Neck pain in association with the dynamic work environment of the fighter pilot is a well-discussed issue. Spinal symptoms in these pilots were recognized as a serious aero medical problem. Often described contributing factors of neck pain in this population are head movements under high +Gz load, seat-back angle, forward bent posture, head worn equipment, the use of night vision goggles and nu...
