TLR and Vestibular Functioning

I have found that checking the TLR (Tonic Labyrinthine Reflex) is often a way to measure vestibular functioning (gravity sense). However, vestibular functioning can be affected by other movements that do not have to do with the tilting of the head. Sucking on a crazy straw and blowing a faceted bead can activate the inner ear and the vestibular system. Jaw clenching can also stress the vestibular system. Today a client used a crazy straw and did 8 consecutive suck/swallows. A few seconds later, ears began to blaze, which is a state change sign, and he got rather disregulated. It took 20 minutes for him to re-regulate. This client had a strong head movement vestibular measure. Obviously ocular-vestibular activities alone are not the entire story.
