The case group received 24 sessions of vestibular rehabilitation protocol, and conventional rehabilitation was performed in the control group (i.e., 3 sessions each week, each lasted about 60 minutes).

Both fatigue (<i>P</i> ≤ 0.001) and ADL (<i>P</i> ≤ 0.001) improved significantly more in the vestibular intervention group than in the control one. <i>Conclusion</i>.
