Craniosacral therapy (CST) is a form of bodywork or alternative therapy that uses gentle touch to palpate the synarthrodial joints of the cranium. It is based on fundamental misconceptions about the nature of the human skull and is promoted as a cure-all for a variety of health conditions.[1][2][3]

CST therapy was invented in the 1970s by John Upledger, an osteopathic physician, as an offshoot of cranial osteopathy, which had been devised in the 1930s by William Garner Sutherland.[2][4]

CST is a pseudoscience, and its practice quackery.[5][6] Medical research has found no good evidence that either CST or cranial osteopathy confers any health benefit, and they can be harmful, particularly if used on children or infants.[2][7][8] The basic assumptions of CST are not true, and practitioners produce conflicting and mutually exclusive diagnoses of the same patients.[9]

Effectiveness and safety

Practitioners of CST claim it is effective in treating a wide range of conditions, sometimes claiming it is a cancer cure, or a cure-all.[1][3][8] Practitioners particularly advocate the use of CST on children.[3] The American Cancer Society caution that CST should never be used on children under age two.[2] Pediatricians have expressed concern at the harm CST can cause to children and infants.[8]

CST is potentially harmful.[10] There have been cases of people with head injuries suffering further injury as a result of CST.[2] If used as an alternative for legitimate therapy for a serious condition, choosing CST can have serious adverse consequences.[2]

According to the American Cancer Society, although CST may relieve the symptoms of stress or tension, "available scientific evidence does not support claims that craniosacral therapy helps in treating cancer or any other disease".[2] Cranial osteopathy has received a similar assessment, with one 1990 paper finding there was no scientific basis for any of the practitioners' claims the paper examined.[7]

In October 2012 Edzard Ernst conducted a systematic review of randomized clinical trials of craniosacral therapy. He concluded that "the notion that CST is associated with more than non-specific effects is not based on evidence from rigorous randomised clinical trials."[11] Commenting specifically on this conclusion, Ernst wrote on his blog that he had chosen the wording as "a polite and scientific way of saying that CST is bogus."[3] Ernst also remarked that the quality of five of the six trials he had reviewed was "deplorably poor", a sentiment that echoed an August 2012 review that noted the "moderate methodological quality of the included studies."[12]

Ernst criticized a 2011 systematic review performed by Jakel and von Hauenschild for inclusion of observational studies and including studies with healthy volunteers.[11] This review concluded that the evidence base surrounding craniosacral therapy and its efficacy was sparse and composed of studies with heterogeneous design. The authors of this review stated that currently available evidence was insufficient to draw conclusions.[13]

The evidence base for CST is sparse and lacks a demonstrated biologically plausible mechanism. In the absence of rigorous, well-designed randomized controlled trials,[14][15] it is a pseudoscience,[6] and its practice quackery.[5]

Technique

Craniosacral therapy is an unregulated trade. Practitioners do not have to have completed a defined training program and are not answerable to a professional body.[16]

The therapist lightly palpates the patient's body, and focuses intently on the communicated movements. A practitioner's feeling of being in tune with a patient is described as entrainment.[17]

Tests show that CST practitioners cannot in fact identify the purported craniosacral pulse, and different practitioners will get different results for the same patient.[18] The idea of a craniosacral rhythm cannot be scientifically supported.[19]

History and conceptual basis

The fundamental concepts of cranial osteopathy and CST are inconsistent with the known anatomy and physiology of the human skull, brain and spine.[2] Edzard Ernst has written "to anyone understanding a bit of physiology, anatomy etc. [CST] looks like pure nonsense".[3]

In common with many other varieties of alternative medicine, CST practitioners believe all illness is caused by energy or fluid blockages which can be released by physical manipulation.[8] They believe that the bones of the skull move in a rhythmic pattern which they can detect and correct.[8]

Cranial osteopathy, a forerunner of CST, was originated by osteopath William Sutherland (1873–1954) in 1898–1900. While looking at a disarticulated skull, Sutherland was struck by the idea that the cranial sutures of the temporal bones where they meet the parietal bones were "beveled, like the gills of a fish, indicating articular mobility for a respiratory mechanism."[12]

John Upledger devised CST. Comparing it to cranial osteopathy he wrote: "Dr. Sutherland's discovery regarding the flexibility of skull sutures led to the early research behind CranioSacral Therapy – and both approaches affect the cranium, sacrum and coccyx – the similarities end there."[20] However, modern day cranial osteopaths largely consider the two practices to be the same, but that cranial osteopathy has "been taught to non-osteopaths under the name CranialSacro therapy."[21]

Practitioners of both cranial osteopathy and craniosacral therapy assert that there are small, rhythmic motions of the cranial bones attributed to cerebrospinal fluid pressure or arterial pressure. The premise of CST is that palpation of the cranium can be used to detect this rhythmic movement of the cranial bones and selective pressures may be used to manipulate the cranial bones to achieve a therapeutic result.[22] However, there is no evidence that the bones of the human skull can be moved by such manipulations.[23]

From 1975 to 1983, Upledger and neurophysiologist and histologist Ernest W. Retzlaff worked at Michigan State University as clinical researchers and professors. They assembled a research team to investigate the purported pulse and further study Sutherland's theory of cranial bone movement. Upledger and Retzlaff went on to publish their results, which they interpreted as support for both the concept of cranial bone movement, and the concept of a cranial rhythm.[24][25][26] Later independent reviews of these studies concluded that they presented no good evidence for the effectiveness of craniosacral therapy or the existence of the proposed cranial bone movement.[23]
