A study of craniosacral therapy in traumatic brain injury rehabilitation sits in an unusual spot in the CST literature. It ran in an inpatient rehab setting from 1978 to 1992, with patients who had serious neurological injuries. Not the typical CST client. The findings carry weight for anyone considering CST in a neurological context.
The study recorded both the craniosacral findings practitioners identified during assessment of TBI patients, and cases where adverse outcomes followed treatment. Iatrogenesis — harm caused by treatment — matters here. Not because it's common, but because it's the field's job to acknowledge when treatment has contributed to harm.
Knowing what the study found, and what has changed in the field since, gives a fuller picture of CST's relationship to neurological presentations.
What the study examined
The study took place in an outpatient rehabilitation unit using craniosacral therapy as part of a broader rehab approach for patients recovering from traumatic brain injury. Over the years covered, practitioners recorded their craniosacral assessments and tracked patient outcomes, including any adverse events that came up alongside treatment.
The premise of using CST in TBI was that the injury might have disrupted craniosacral structures — the dural membranes, cerebrospinal fluid dynamics, the bony relationships of the skull — and that addressing those disruptions could help recovery. From inside the CST framework that's a plausible hypothesis. To become a clinical recommendation it would need stronger evidence.
What the study found was a mix. Practitioners' notes on the craniosacral findings they believed they were detecting in TBI patients, alongside documentation of cases where adverse outcomes followed treatment. Iatrogenesis is the term used when treatment looks to have caused or contributed to harm, and some of the documented cases fell under it.
What iatrogenesis means here
Iatrogenesis is a medical term for harm caused by medical treatment or advice. It covers everything from medication side effects to surgical complications to a physical therapy technique that aggravates an injury. With CST, iatrogenic effects might mean increased neurological symptoms, headache, dizziness or other adverse changes that came on after treatment and seemed connected to it.
In a TBI population the risks are higher than in the general population. People recovering from brain injury can have raised intracranial pressure, disrupted cerebrospinal fluid dynamics, healing neural tissue, or other vulnerabilities that make any work on the cranium — even gentle work — potentially significant. What's low-risk for someone with chronic tension headaches isn't necessarily low-risk for someone six weeks out from a serious head injury.
Documenting those adverse cases was an act of professional responsibility. The field needed to know its techniques could harm certain populations. The researchers who wrote them up helped move CST toward a more safety-conscious approach in neurological settings.
How safety protocols have moved on
The study covers 1978 to 1992 — a stretch when CST was still relatively young as a formalised therapy and when the understanding of contraindications was still being worked out. In the decades since, the field has built more explicit safety protocols for working with neurological presentations.
Current CST training programmes include material on contraindications, with specific guidance for head injury, recent surgery and active neurological conditions. The general principle: more caution — lighter touch, shorter sessions, more careful watching of how the client responds — wherever the nervous system is under stress or in active recovery.
For anyone with a TBI history considering CST now, the honest advice is the same. Talk to your neurologist or rehab specialist before starting. A well-trained practitioner will also ask about your medical history and will adapt their approach, or decline to work with you, based on what they hear. The field has learned from its early experience, and those lessons are now built into how good practitioners handle neurologically complex cases.
The TBI case study is a reminder that CST, like any therapy, calls for appropriate caution in certain clinical contexts. Documenting adverse events in an early neurological rehab setting helped the field develop better safety protocols — protocols that keep evolving as the evidence grows.
