Is the bedside timed vibration test reliable?
The timed vibration test (TVT) is an easy-to-perform bedside sensory test; however, its reliability is not well established at sites commonly used for clinical testing. We evaluated intra- and interrater reliability of the TVT in a healthy control cohort of 25 adult volunteers and assessed the influence of neurologic training on TVT. Intrarater [intraclass correlation coefficient (ICC) range 0.79-0.92] and interrater (ICC range 0.0.82-0.95) reliability of TVT was high at different sites, which suggests that TVT is a reliable bedside examination when performed using a standardized protocol.
