Conclusions:
It was shown that practicing with a tangible head model with semicircular canals is a useful educational tool for learning the physical treatment for BPPV.
Objectives:
To assess the efficacy of using a tangible head model with semicircular canals to teach the physical treatment for BPPV.
Methods:
This study compared the number of canalith particles in the posterior semicircular canal that 20 participants could move from the ampulla to the utricle, before and after practicing with the tangible model.
Results:
Before practicing with the model, they could move 2.5 (mean value) of 10 canalith particles. However, after practicing, they could move 6.6 (mean value) of 10 canalith particles. There was a statistical difference (p < 0.01) between the two trials.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
