Introduction: The Cervical Vestibular Evoked Myogenic Potential (cVEMP) is used to evaluate the integrity of saccule and inferior vestibular nerve. There are a lot of factors affecting cVEMP results including stimulus types. This study was carried out to determine the effects of different stimuli on cVEMP results and its test-retest reliability. Materials and method: 25 normal hearing subjects were recruited. The cVEMP testing were performed in 2 sessions with 1 week gap between each sessions. The cVEMP waveforms were recorded in sitting upright position with electrodes placed at; i) upper one-third of sternocleidomastoid muscle for active electrode, ii) suprasternal notch for inactive electrode and, iii) middle of forehead for the ground electrode. The stimuli (500Hz tone burst, click, narrowband chirp and broadband chirp) were presented via insert phone at 95dBnHL. The cVEMP results (P13-N23 peak-to-peak amplitude, P13 latency and N23 latency) were recorded. Results: Result showed; i) 500Hz tone burst produced significantly largest amplitude; ii) narrowband chirp produced significantly shortest P13 latency; iii) broadband chirp produced significantly shortest N23 latency; iv) no significant difference of P13 and N23 latency were observed between two sessions; and v) significant difference of P13-N23 amplitude were observed between two sessions for all stimuli except for narrowband chirp. Conclusion: The 500Hz tone burst was observed to be the most ideal stimulus (produce highest amplitude). All stimuli produced good test-retest reliability in terms of latency. However, most of the stimuli produced poor test-retest reliability in terms of amplitude except for narrowband chirps.

Purpose Simultaneous recording of cervical (cVEMP) and ocular (oVEMP) vestibular evoked myogenic potentials aids in reducing the testing time when compared to conventional sequential recordings. The purpose of this study was to examine the test–retest reliability of sequential and simultaneous acquisitions of cVEMP and oVEMP. Method cVEMP and oVEMP were recorded in 35 normal-hearing individuals. The cVEMP and oVEMP were obtained using sequential and simultaneous methods. The VEMP recordings were performed across 3 sessions. The 1st 2 recording sessions were consecutive with a gap of 5 min between sessions. The 3rd recording session was after a gap of 3–5 days. Results Both simultaneous and sequential recordings showed fair-to-good test–retest reliability for latencies and amplitude of cVEMP and oVEMP. Conclusion Simultaneous cVEMP and oVEMP recordings can be used to obtain fast VEMP recording with test–retest reliability comparable with that of sequential recording.

Abstract Background The Performance and Fitness (PERF-FIT) test battery for children is a recently developed, valid assessment tool for measuring motor skill-related physical fitness in 5 to 12-year-old children living in low-income settings. The aim of this study was to determine: (1) inter-rater reliability and (2) test-retest reliability of the PERF-FIT in children from 3 different countries (Ghana, South Africa and the Netherlands). Method For inter-rater reliability 29 children, (16 boys and 13 girls, 6–10 years) were scored by 2 raters simultaneously. For test–retest reliability 72 children, (33 boys and 39 girls, 5–12 years) performed the test twice, minimally 1 week and maximally 2 weeks apart. Relative and absolute reliability indices were calculated. ANOVA was used to examine differences between the three assessor teams in the three countries. Results The PERF-FIT demonstrated excellent inter-rater reliability (ICC, 0.99) and good test-retest reliability (ICC, ≥ 0.80) for 11 of the 12 tasks, with a poor ICC for the Jumping item, due to low spread in values. A significant difference between first and second test occasion was present on half of the items, but the differences were small (Cohen’s d 0.01–0.17), except for Stepping, Side jump and Bouncing and Catching (Cohen’s d 0.34, 0.41 and 0.33, respectively). Overall, measurement error, Limits of Agreement and Coefficient of Variation had acceptable levels to support clinical use. No systematic dissimilarities in error were found between first and second measurement between the three countries but for one item (Overhead throw). Conclusions The PERF-FIT can reliably measure motor skill related fitness in 5 to 12-year-old children in different settings and help clinicians monitor levels of fundamental motor skills (throwing, bouncing, catching, jumping, hopping and balance), power and agility.

Introduction: Schroeder-phase masking test has been found to be highly useful in providing information on the cochlea phase response that was not previously discovered. Conventional Three Alternative Forced Choice (3AFC) method of conducting Schroeder phase masking takes a long testing time (around 45 minutes) and could possibly limit the valuable information that may be gathered from this test. A faster Schroeder-phase masking method which is able to cut down almost 80% of the testing time has been developed, and has been proven reliable for normal hearing population. This study aims to extend the reliability measures to hearing impaired population. Methods: This is an observational study involving 10 normal hearing and 6 sensorineural hearing loss subjects. Schroeder phase masking functions were measured at 500 Hz, 1 kHz and 2 kHz (75 dB A) using the conventional and fast methods to find the agreement between two methods. The fast method was measured in two sessions to find the test–retest reliability. Results: The fast method showed; i) good agreement with the conventional 3 AFC method-no significant difference of masked thresholds between two methods at majority of the tested conditions (p>0.05), ii) good test retest reliability- no significant difference of masked thresholds between two sessions (p>0.05). Conclusions: Proven to be a reliable method in both normal hearing and hearing impaired population, the faster method could potentially facilitate more Schroeder phase masking experiments in investigating the fundamental of sound processing and auditory perception.

Abstract Background Masseter vestibular evoked myogenic potential (mVEMP) is a recent tool for the assessment of vestibular and trigeminal pathways. Though a few studies have recorded mVEMP using click stimuli, there are no reports of these potentials using the more conventional VEMP eliciting stimuli, the tone bursts. Purpose The aim of the study is to establish normative values and determine the test–retest reliability of tone burst evoked mVEMP. Research Design The research design type is normative study design. Study Sample Forty-four healthy participants without hearing and vestibular deficits in the age range of 18 to 50 years participated in the study. Data Collection and Analysis All participants underwent mVEMP testing using 500 Hz tone-burst stimuli at 125 dB peSPL. Ten participants underwent second mVEMP testing within 1 month of the initial testing to estimate the test–retest reliability. Results Tone burst mVEMP showed robust responses in all participants. There were no significant ear and sex differences on any mVEMP parameter (p > 0.05); however, males had significantly higher EMG normalized peak-to-peak amplitude than females. Intraclass correlation coefficient (ICC) values of tone burst mVEMP showed excellent test–retest reliability (ICC >0.75) for ipsilateral and contralateral p11 latency, ipsilateral EMG normalized p11-n21 peak to peak amplitude, and amplitude asymmetry ratio. Fair and good test–retest reliability (0.4 < ICC > 0.75) was observed for ipsilateral and contralateral n21 latency, contralateral EMG normalized peak-to-peak amplitude, and amplitude asymmetry ratio. Conclusion Tone burst mVEMP is a robust and reliable test for evaluating the functional integrity of the vestibulomasseteric reflex pathway.

One of the recent diagnostic tests to assess the function of otolithic organs is through vestibular evoked myogenic potential (VEMP) testing. There are equivocal findings on effect of aging on ocular VEMP (oVEMP) parameters with reference to latencies. Hence this study was taken up to investigate the age related changes in oVEMP parameters. This present study considered 30 participants in each age group i.e., young adults, middle-aged adults and older adults. oVEMP were recorded using insert earphone at 100dBnHL at 500hZ short duration tone burst. The results showed in older adult significant difference in response rate, latencies and amplitude as compared to young and middle adult. Hence age should be taken into consideration when interpreting oVEMP results.
