Exercise and Vestibular Hypofunction

Interventional study with two randomized groups (attention control '\[AC\] and exercise group,\[EX\]) with assessment pre and post-intervention (8 weeks) and 6 months follow-up. The AC group will perform only the home vestibular rehabilitation exercises that are usually prescribed in consultation with this type of patient, performing the same assessments as the intervention group in all phases of the study. The participants in the EX group will exercise under the supervision of specialists in exercise and sports physical educators two non-consecutive days per week for eight weeks at the Faculty of Education and Sport of the University of the Basque Country (UPV/EHU). All sessions will start and end with blood pressure measurements and exercise intensity will be monitored by heart rate monitors (Polar Electro, Kempele, Finland) and through the original Borg scale (6-20). All sessions will include a 5-10 min warm-up with joint mobility exercises and gait technique and a 10 min cooldown with basic stretching exercises and controlled breathing. The main part of the session will consist of: 1) balance exercises, multidirectional displacements and strength with postural control, implementing 8-10 exercises integrating the main muscle groups and motor patterns, 2) aerobic exercise on bicycle (15 min) developed progressively in intensity (R1-mild, R2-moderate, R3-vigorous) implementing an intervallic design at low volume. The physical exercise intensity ranges (R1-mild, R2-moderate, R3-vigorous) will be defined on an individualized basis from the initial stress test and based on ventilatory thresholds. At the end of the intervention, participants will be provided with information on physical activity recommendations. Both intervention and control group patients will have all antivertiginous drugs withdrawn.
