Subjective visual vertical (SVV) in people with chronic unilateral vestibular loss (UVL) has been found to be not reliable. We examined this in relation to interaural head position and neck and trunk orientation. Ten subjects with UVL (mean age 57.6, range 47-65 yr), and 10 age-matched control subjects, all underwent an SVV test, as well as a test of postural control (standing on a computerized tilting platform). In a standard clinical position, the SVV was straight ahead in both groups. In another condition the SVV was straight ahead while the head was tilted towards the ipsilateral side by 30 degrees (right-sided UVL), or towards the contralateral side by 30 degrees (left-sided UVL). In a third condition the SVV was straight ahead while the head was rotated in both directions by 30 degrees. Finally, the position of the SVV was straight ahead while the head was rotated in both directions by 30 degrees. During each condition the subject was instructed to look straight ahead. In both the control and the UVL group the SVV was straight ahead when the head was in the most frontal position, regardless of interaural head position and neck and trunk orientation. In the UVL group the SVV was straight ahead in all head positions when the head was rotated in the same direction as the body. In contrast, the SVV was always deviated towards the side opposite the rotated head when the head was rotated in the opposite direction compared with the body, which was significantly different from the control group. The current study indicates that with chronic unilateral vestibular loss the SVV is direction-specific, i.e., it is no longer straight ahead when the head is rotated towards the side of the lost vestibular function.Treasury Secretary Steven Mnuchin said Friday that President Trump will not meet with House Democrats during a White House meeting on infrastructure. Mnuchin said that while the president would be willing to work with congressional Democrats to come up with a spending deal, he will not be in session with them on May 23. "No. We are not going to have a conversation. This is about infrastructure. It's not about political," Mnuchin told reporters
