Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Vestibular schwannoma (VS) is a benign tumour from Schwann cells surrounding the vestibular nerve, which slowly grows within the internal auditory canal and then into the cerebellopontine angle, leading to a gradual vestibular dysfunction. The slowly progressive alteration of vestibular function allows the gradual implementation of central adaptive mechanisms called vestibular compensation. The total unilateral vestibular deafferentation induced by the surgical tumour removal suddenly leads to a decompensation of this previously compensated situation, which explains why most patients report severe vertigo immediately after surgery and which is responsible for perturbations of the postural control (Parietti-Winkler et al., 2006, 2008, 2010, 2011). Recently, Gauchard et al. (2013) suggested that preoperative and regular physical activity would limit the adverse effects of surgical removal on balance control. Also, patients benefited faster and better from the postoperative vestibular rehabilitation.

Thus, preoperative vestibular rehabilitation, including physical and balance exercises, could help to limit postoperative balance disorders and promote postoperative balance compensation. This could lead to a decrease in the duration and cost of the postoperative management and faster improvement of quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To test this hypothesis, the measured and perceived balance control of the patient and the quality of life will be assessed into two groups: one of two groups will receive preoperative vestibular rehabilitation, carried out by a physiotherapist, and the other not. The assessments will be conducted 45 days and 3 days before surgery, and then 8 days, 30 days, 90 days and 365 days after surgery.
