简要总结
Rotational maneuver is a vestibular rehabilitation method, performed in a supervised manner. Using a rotating chair, subjects are rotated towards the opposite direction of dominant side in order to inhibit this side and simultaneously, stimulate the subordinate side. We propose that the rehabilitative effect is the result of a decrease in the vestibular imbalance, mainly due to a decrease in the response of the dominant vestibular side. Previously, we have shown the short-term effects of this maneuver on patients with recent onset vestibular imbalance. In the present study, we investigated the long-term effects of the rotational maneuver in patients with a history of peripheral vestibular vertigo for at least one year, originally confirmed by clinical tests. Our results show a significant improvement which lasted for >4 weeks after the end of rehabilitation (i.e., the last time tested). Moreover, there seems to be a relationship between the decrease in DP values and a decrease in subjective symptoms. We propose that this maneuver can be used as an effective method for both short- and long-term rehabilitation.

结局指标
主要结局
Directional preponderance (DP)
时间窗: Every 3-7 days for one month
It provides an objective measure of vestibular asymmetry (percentage) in response to rotation. Eye movements are measured by electronystagmography during head rotations to the right and to the left. DP (%) is calculated by the equation: 100 x (max eye velocity for rightward rotations - max eye velocity for left rotations) / (max eye velocity for rightward rotations + max eye velocity for left rotations). Values below 10% are considered normal.
次要结局
- Subjective sense of a decrease in imbalance and dizziness.(every 3-7 days for one month)
