I have no idea what this means. "I thought joint mobilizations (lower ones, like grades 1 and 2), were gentle manipulations." grades 1 or 2 ??

My PT would have me lying on my back and pull gentle tension on my head as she used her finger tips to massage the vertebra so they are 'unlocked' as she gently rocked my head. She would do this after she use her pressure point therapy to cause the muscles to release.

Other than feeling like she left her finger prints in my muscles as she released them, nothing else ever felt uncomfortable or had any pop or crack.

I never sit or lie in any posture that has a pillow or such that tilts my head forward.

My bed pillow does not lift my head when I am on my back.
