Important note: Medicine is an ever-changing science undergoing continual development. Research and clinical experience are continually expanding our knowledge, in particular our knowledge of proper treatment and drug therapy. Insofar as this book mentions any dosage or application, readers may rest assured that the authors, editors, and publishers have made every effort to ensure that such references are in accordance with the state of knowledge at the time of production of the book.

Nevertheless, this does not involve, imply, or express any guarantee or responsibility on the part of the publishers in respect to any dosage instructions and forms of applications stated in the book. Every user is requested to examine carefully the manufacturers leaflets accompanying each drug and to check, if necessary in consultation with a physician or specialist, whether the dosage schedules mentioned therein or the contraindications stated by the manufacturers differ from the statements made in the present book. Such examination is particularly important with drugs that are either rarely used or have been newly released on the market. Every dosage schedule or every form of application used is entirely at the user's own risk and responsibility. The authors and publishers request every user to report to the publishers any discrepancies or inaccuracies noticed. If errors in this work are found after publication, errata will be posted at www.thieme.com on the product description page.

Some of the product names, patents, and registered designs referred to in this book are in fact registered trademarks or proprietary names even though specific reference to this fact is not always made in the text. Therefore, the appearance of a name without designation as proprietary is not to be construed as a representation by the publisher that it is in the public domain.

This book, including all parts thereof, is legally protected by copyright. Any use, exploitation, or commercialization outside the narrow limits set by copyright legislation without the publisher's consent is illegal and liable to prosecution. This applies in particular to photostat reproduction, copying, mimeographing or duplication of any kind, translating, preparation of microfilms, and electronic data processing and storage.

Video 2.1 Demonstration of Romberg testing while on compliant foam. This test isolates the vestibular system by decreasing visual (eyes closed) and proprioceptive (foam pad) influences.

Video 2.2 Demonstration of the use of Frenzel goggles. This apparatus may detect vestibular nystagmus by decreasing visual fixation. The second part of the video shows nystagmus while using this instrument.

Video 2.3 Smooth pursuit with normal endpoint in left gaze position.

Video 2.4 Lateral gaze direction changing nystagmus such that left gaze is left beating and right gaze is right beating, in addition abnormal gait that is slightly wide based and right leaning. Consistent with central pathology.

Video 2.5 Normal gaze testing and facial nerve function.

Video 2.6 Classic example of downbeating nystagmus consistent with central lesion.

Video 2.7 Classic example of upbeating nystagmus consistent with central lesion.
