Taming the Zebra: Tethered Cord and Cranio-Cervical Instability in Hypermobility with Heather Purdin
Host Dr. Libby Hinsley welcomes physical therapist and manual therapist Heather Purdin, co-author of “Taming the Zebra,” to discuss her book and her biopsychosocial approach to treating hypermobility syndromes. The conversation continues by highlighting tethered cord syndrome, its key features, imaging considerations, conservative/manual approaches, and surgical cautions. They also discuss cranio-cervical instability versus a hypermobile neck, the role of inflammation/MCAS, stabilization strategies, and referrals, and share where to find Purdin’s resources and courses.
