Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...in the normal man orientation is a complex function in which the vestibular apparatus, the muscular, arthrodial, and tactile senses and sight all take part. When sight is lost, muscular and arthrodial impressions become more sensitive and accurate. When one vestibular apparatus is destroyed, the opposite labyrinth must become accustomed to unopposed, unilateral activity, and the muscular, arthrodial, and tactile impressions of space and position must be immensely increased. Until this process of involuntary education is well advanced, it is not surprising that the individual experiences occasional vertigo and ataxia, though he does not exhibit nystagmus and may show no constant tendency to fall in any given direction. Clinical Manifestations of Vestibular Paralysis. We know that the onset of diffuse suppurative labyrinthitis, or the removal of one labyrinth, is invariably followed by very severe vertigo and disturbances of equilibrium, --these symptoms being the result of hyperactivity of the sound, unopposed labyrinth. In other words, sudden destruction or removal of one labyrinth is in effect equivalent to irritation of the remaining sound vestibular apparatus. After these symptoms of vestibular irritation have completely subsided, the patient is comparatively comfortable. He has now passed the stage when sudden movements of the head cause nystagmus and its attendant phenomena, and may be up and walking about his room. On getting out of bed in the morning, however, and on making any sudden and pronounced changes in the position of his body--e. g., as in stooping over to pick up something from the floor, or even on suddenly rising from the sitting posture, --he becomes momentarily dizzy, and may even require support to prevent his falling.
