Primary Outcome Measures

Name	Time	Method
Subjective Postural Vertical (SPV) measurement on two consecutive days:<br>The SPV is measured with the Spacecurl. The examiner slightly deflects the subject (coronal and sagittal plane) and leads him slowly (1.8 °/s) back to the vertical. The subject beckons to the investigator (verbally or by pressing a button) when he feels vertically aligned. He also has the possibility to self-adjust his position to the vertical (magnitude estimation and magnitude production). The degrees are measured on a calibrated scale mounted on the Spacecurl. In addition, they are recorded by a Accelometer, which contains a gyroscope.

Secondary Outcome Measures

Name	Time	Method
Measurement on day 1:<br>Subjective visual vertical (SVV)<br>The bucket method was evaluated by Zwergal et al. (2009) as an easily performed and reliable bed-side test to measure the SIA. For the SVV test the subject sits upright and looks into a bucket. The visual field is completely covered by the edge of the bucket. On the bottom of the bucket is a dark, straight line. The bucket is rotated slowly by the examiner from different starting positions in the direction of position zero. The subject indicates when he determines the dark line as vertical and the investigator reads out the deviation in degrees on a scale on the outside of the bucket.<br><br>Haptic Subjective Vertical (SHP)<br>The SHP is measured with a stick affixed on a vertical board . The subject turns it with his eyes closed from various starting positions in the position where they guess the stick is vertically. The degrees can be read out from a scale on the board.
