The osteopathic lesion is not to be regarded as a malformation, or even a maladjustment of structures, but should be defined in terms of mobility. That is to say, the lesion is a physiological and not an anatomical condition. It is a modification of the movements of extension, flexion, rotation and side-bending as an isolated change, or an abnormal and artificial group movement.
In the lesion field, the involuntary movements are chiefly at fault, and the technique of diagnosis and treatment is to be discussed from the point of view of mobility, locally and generally. The physiological movements for the purposes of adjustment are represented by the normal movements of the body trunk, the extremities, and parts of these in so far as they are unified in the body activity. Therefore the central factor to be considered, is the gravity centre and the gravity lines of the body, all movements being around some axis in relation to these central lines, or points.
The movements are in circles, or modifications of circles. The foundation of the body and its equilibrium of movement is found in the pelvis, which represents a circle, or its modification. These movements are all in relation to the sacro-iliac articulations, the fifth lumbar and the sacral articulation on either side of the pelvis. Also the sacro-coccygeal articulation as a unit of the gravity line movement and the triangles of the body trunk. Lastly the femoral articulations in relation to the innominates, forming the angles of the basal triangles of support, and foundation for the trunk and the extremities.
The skeletal structure is the objective factor since the bones are fixed and solid and the foundation of movement, that is to say, fixity converted into mobility. The inter-relations between the bones are determined by the soft, mobile and elastic structures, cartilage, ligament, muscle and fascia. This means that the correlation between fixity and mobility depends on elasticity, and this is the reason why we emphasise the importance of tissue tonicity in the treatment. Irritation in the blood vessels, nerves and soft tissues arise from a mechanico-physiological interruption, suspension or irritation of the three factors to which reference has been made, namely,….
