Effects of a Vestibular Rehabilitation Maneuver

February 6, 2019 updated by: Dr Nayer Rassaian, Day General Hospital.

Short-term and Long-term Effects of the Rotational Maneuver in Patients With Chronic Vestibular Imbalance

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Directional preponderance (DP)
Time Frame: 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.
Every 3-7 days for one month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Subjective sense of a decrease in imbalance and dizziness.
Time Frame: every 3-7 days for one month
Patients report the intensity and frequency of their symptoms as a measure of subjective improvement on a scale of 1 - 10, with 10 representing the most improvement.
every 3-7 days for one month
