lnvoluntary Motion - The Cranial Rhythm

Cranial osteopaths are trained to feel a very subtle, rhythmical shape change that is present in all body tissues. This is called Involuntary Motion or the Cranial Rhythm.  The movement is of very small amplitude, therefore it takes practitioners with a very finely developed sense of touch to feel it. This rhythm was first described in the early 1900's by Dr. William G. Sutherland and its existence was confirmed in a series of laboratory tests in the 1960's and '70's.
Tension in the body disrupts the cranial rhythm. Practitioners compare what your rhythm is doing to what they consider ideal. This shows them what stresses and strains your body is under at present, and what tensions it may be carrying as a result of its past history. It also gives them an insight into the overall condition of your body, for example if it is healthy, or stressed and tired.

Accumulation of stress and strain in the body
When we experience physical or emotional stresses our body tissues tend to tighten up. The body may have been able to adapt to these effects at the time, but a lasting strain often remains. Any tensions which remain held in the body can restrict its free movement. Gradually the body may find it more and more difficult to cope with accumulated stresses and symptoms may develop.
