Vestibular compensation in patients with stroke

Takeaway

  • Lesions of the posterior insular cortex (IC) in patients with tilts of subjective visual vertical (SVV) should undergo intensive vestibular rehabilitation programs. 

Why this matters

  • The tilt of the perceived SVV is a sensitive and frequent clinical manifestation of vestibular tone imbalance. Unilateral lesions involving the peripheral vestibular end organ or pathways from the vestibular nuclei are the causes of vestibular tone imbalance.

  • Although cerebellar lesion locations have been identified that affect vestibular compensation, there is no data on cortical lesion location as a predictor of compensation from tilt of SVV.
