ジャーナル フリーGreater occipital nerve block was performed on patients with nuchal tenderness and resulting changes in the equilibrium function were investigated. Most patients had symptoms related to hypertonicity of the nuchal muscles. Disequilibrium was improved after greater occipital nerve block. Greater occipital nerve block was most effective in patients who showed abnormality only in the righting test. Greater occipital nerve block was more effective in patients who were positive in the equilibrium test with adrenalin-loading.抄録全体を表示PDF形式でダウンロード (1589K) -

ジャーナル フリーThe eye-head coordination during lateral gaze was examined in normal subjects and patients with unilateral and bilateral labyrinthine lesions. Eye movements were recorded by d. c. electro-oculography, and head rotation was measured using a newly devised apparatus equipped with two terrestrial magnetic sensors. This apparatus made it possible to record head rotation without mechanical restraint. From the results thus obtained it was clarified that the illusory motion of the surroundings in unilateral labyrinthine lesion occurs exclusively when the head moves to the involved side, and its direction is opposite to that of the head movement.抄録全体を表示PDF形式でダウンロード (749K) -

ジャーナル フリーOn the assumption that cerebral and labyrinthine circulatatory insufficiency plays a part in the mechanism of vertigo, the role of the autonomic nervous system, especially the sympathetic nervous system, in the occurrence of vertigo was studied. It was found that there are problems regarding systemic sympathetic reactions such as abnormalities in Schellong's test, fluctuations in blood pressure and changes in blood properties (serum lipids, viscosity, platelet functions) and local sympathetic reactions such as difference in blood flow between the right and left vertebral arteries due to the difference in tension between the right and left parts of the cervical sympathetic system.
It is considered that these problems cause ischemia in the unilateral area of the central vestibular system or ischemia in the unilateral area of the peripheral vestibular system, being combined with local factors of the inner ear, and create differences in excitability between the right and left vestibular systems, and bring about vertigo.抄録全体を表示PDF形式でダウンロード (576K) -

ジャーナル フリーDisturbance in space sense or space perception can be classified into four groups, such as vertigo, dizziness, blackout and oscillopsia.
Fundamental elements in vertigo and dizziness are assumed to be the abnormal sensation in motion, the abnormal positional sensation and the discordance or confusion in space perception related to the body equilibrium reflexes and to the memory.
The occurrence of turning sensation in the acute stage of unilateral pe r i pheral vestibular disease or in the postrotatory sensation in the normal case can be explained by the relationship between vertigo and spontaneous nystagmus or by the relationship between induced vertigo and postrotatory nystagmus.抄録全体を表示PDF形式でダウンロード (1088K) -

ジャーナル フリーVestibular function tests include tests of two main systems, vestibulospinal and vestibulo-oculomotor systems. Righting reflex and deviation of the extremities are routinely examined by vestibulo-spinal system test. Functions of the vestibulo-oculomotor system are examined by positional and positioning nystagmus tests, optokinetic nystagmus and eye tracking tests, all of which greatly contribute to differential diagnosis of vertigo of the peripheral and central lesions.抄録全体を表示PDF形式でダウンロード (260K) -

ジャーナル フリーThe role of the plantar reflex in control of bodily sway was examined stimulating the plantar mechanoreceptor. The stimulations were applied using boards with shotgun balls, that were placed 1,1.5, and 2 cm a part. The subjects were told to stand straight on the board and their body sway was analyzed by the stabilometer.
The results of the analysis indicated that factors such as the area of sway, the accumulated shift length caused by the sway and the velocity of sway all tended to decreased depending on the type of stimulation.
Experiments on neuron discharge from the tibial nerve fibers revealed that the number of neuron discharge was markedly higher when stimulations were given than without stimulation. These findings suggested that the increase in plantar mechanoreceptor input information was involved in a higher central nervous system control mechanism rather than the spinal level control system, and it was particularly effective in causing reflexes such as footing adjustment when right and left sway occur.抄録全体を表示PDF形式でダウンロード (2687K)
