Using Unidirectional Rotations to Improve Vestibular System Asymmetry in Patients with Vestibular Dysfunction.

The vestibular system provides information about head movement and mediates reflexes that contribute to balance control and gaze stabilization during daily activities. Vestibular sensors are located in the inner ear on both sides of the head and project to the vestibular nuclei in the brainstem. Vestibular dysfunction is often due to an asymmetry between input from the two sides.

Rebalancing the Vestibular System by Unidirectional Rotations in Patients With Chronic Vestibular Dysfunction.

Vestibular dysfunction is a common disorder that results in debilitating symptoms. Even after full compensation, the vestibulo-ocular reflex (VOR) could be further improved by using rehabilitation exercises and visual-vestibular adaptation. We hypothesized that in patients with asymmetric vestibular function, the system could be rebalanced by unidirectional rotations toward the weaker side (i.

[A change to the traditional medicine in Persia?].

Until the 19th century, medicine in Persia is mainly based on the humoral theory. According to some authors, the introduction of anatomical pathology principles is due to the particular political and health circumstances of this century and the intellectual evolution of Persian physicians. By making a comparison between the text of Shirazi, the prominent Persian physician of the 19th century, and the writings of Avicenna on cholera and heyze (acute diarrhea), this article tests this hypothesis.
