Cranial Sachial therapy

I doubt I spelled it right but has anyone heard of this? It is in the same vein as joint compression...joint compression for your head, so to speak.I had heard something about this and wondered if anyone had any experience with this.

We are getting out of town for a week..going camping in Maryland and taking a break. Tristan is in ESY but we all need to see the ocean for alittle while.

"See" you all soon and thanks for any info you may come up with.
