Description

Vestibular function goes hand in hand with visual function. When you understand how these systems are intertwined, you can immediately resolve vision-related health and function concerns in many clinical populations: headache, diplopia (double-vision), blur, reading and learning deficits and discomfort, attention problems, photophobia (light sensitivity). Explore:

- How visual-vestibular dysfunction impacts brain injury treatment

- The role of oculomotor and vestibular dysfunction in reading disability and praxis

- Testing techniques that you can modify in your own practice: BPPV, Post-rotational nystagmus, peripheral vs. central visual fields, strabismus and other ocular restrictions.

- Opportunities for “coordinated firing” with multimodal experiences to promote the integration of visual and vestibular function.

- Use of prism in visual perceptual, visuomotor, and oculomotor therapies

- Training full body awareness, sensorimotor conditioning, visual-vestibular patterning with evidence-based tools

Accelerate and bolster outcomes in visuomotor, oculomotor, and perceptual training with simple tests and techniques you can implement right away.
