摘要: The influence of dorsal neck proprioceptive inputs on vestibular compensation was investigated in 21 patients with unilateral dysfunction. Subjects neither had history spontaneous nystagmus nor disequilibrium, indicating that they were a good compensated stage. However, marked induced by applying vibratory stimulation to the patients, using vibrator frequency 110 Hz. three-dimensional as analyzed computerized eye movement analysis system. Twelve (57%) demonstrated three components movement. All subjects showed horizontal component directed towards contralateral side lesion. Vertical and torsional exhibited 18 14 subjects, respectively. average percentages slow phase velocity horizontal, vertical 57%, 23% 20%, No tendency any observed. Furthermore, order investigate relation between outputs, especially semicircular canal author compared direction orientation canals. Normalized vectors calculated. In most related canal. These results suggest controlling inputs, vibration can cause discompensation vestibularly well-compensated dysfunction secondary lesion, have great vestibulo-ocular reflex pathways. few This suggests may also be
