Hi Nicole! Thanks for this question! Research has shown that habituation does not yield significant improvement in function/disability in individuals with bilateral vestibular hypofunction.
Here are a couple sources:
– Herdman (2006): “Habituation exercises are not appropriate for patients with BVH. In contrast to patients with UVH, patients with BVH
performing a program of habituation exercises have no significant improvement in disability, even after 3 months of exercises (Telian et al, 1991).”
– Han (2011): “Habituation exercises are inappropriate for patients with bilateral vestibular loss, because they are designed to decrease
unwanted responses to vestibular signals rather than to improve gaze or postural stability.”
