Please note that according to a 2002 study published by the NIH, the scalenes rotate to head ipsilaterally. I know many texts, including Biel's Trail Guide, say otherwise.
Thank you for that information. The text sources that use in the classroom list only the anterior scalene as a rotator and a poor one at that. But the multiple a texts all list it as a slight contra lateral rotator. Since the stable rib (insertion) is anterior to the superior moving TvP of the Cervical spine. The head (when firing a scalene unilaterally)would slightly rotate the head away from the tested side.
Super helpful, never had anatomy explained this well before, thanks!!
We are glad you enjoyed our content !! I do my best to utilize anatomical language as I explain the muscle palpations and treatment demos.
Fantastically explained!
Glad it was helpful!
This was super helpful!! Thank you!
