The purpose of this session is to present data on the patterns of clinical findings in Veterans referred for vestibular assessment. Specifically, we will examine the proportion of abnormalities of the horizontal semi-circular canal and the otolith organ pathways.

Survey research was conducted to explore Speech-Language Pathologists’ (SLPs) perceptions and experiences collaborating with Registered Dietitians (RDs) in the pediatric population. 107 SLPs in different settingsparticipated. Findings indicate SLPs were not exposed to RDs or the role of nutrition in their didactic and clinical training. Rather this exposure occurred once they were in the field practicing as an SLP. A clear need was identified regarding graduate and continued education on collaboration between SLPs and RDs.

The otolith organs (the saccule and utricle) are located in the inner ear and sense linear acceleration, head tilt, and gravity. Recently, the vestibular evoked myogenic potential (VEMP) and the subjective visual vertical (SVV) have been described as clinical tests for otolith function. VEMPs are short latency electromyograms (EMG) evoked by high-level acoustic and vibratory stimuli recorded from surface electrodes over the tonically contracted SCM muscles (cervical VEMP) or extra-ocular muscles (ocular VEMP). The SVV is a psychophysical measure of the angle between perceptual vertical and true (gravitational) vertical and can be measured during unilateral centrifugation (off-axis eccentric rotation). The purpose of this paper is to discuss the clinical use and recent developments of the cervical VEMP, ocular VEMP, and SVV as tests of saccular and utricular function.

The Motion Sensitivity Test (MST) is a clinical protocol designed to measure motion-provoked dizziness during a series of 16 quick changes to head or body positions. The MST has been used as a guide for developing an exercise program for patients with motion-provoked dizziness and as a treatment outcome measure to monitor the effectiveness of vestibular rehabilitation therapy. This study determined validity, test-retest reliability, and interrater reliability of the MST. Fifteen individuals with motion-provoked dizziness and ten control individuals were tested during sessions occurring 90 min and/or 24 hr after baseline testing. The MST was found to be reliable across raters (intraclass correlation coefficient [ICC] = 0.99) and test sessions (ICC = 0.98 and 0.96). Test validity was good. The results indicated that the MST can be used reliably in clinical practice to develop exercise programs for patients with motion-provoked dizziness and to provide evidence of intervention efficacy
