Yes J A, movement that supports safe, neurologically-informed movement of the neck, head, eyes and vestibular system is valuable and rare to find in the Pilates environment. I teach a sequence in supine on the Trapeze Table with head supported by a sling. You will find this in the Pilates Anytime workshop I recorded with Tom Myers, Interoception in Pilates. In addition, page 230 of my book Fascia in Motion(Handspring 2017) shows this and other sequences in the chapter on screen devices. Warm wishes!

Juicy rotations and extensions!  Feeling good! Thank you :)
