Fascial distortion model

from Wikipedia, the free encyclopedia

The fascia distortion model (FDM), from the Latin fascia “bundle” and distorsio “twisting / dislocation ”, is a concept from osteopathy . Scientific studies on FDM are not available. The theory and effectiveness of the therapy are controversial.

The FDM was presented in 1991 by the American emergency physician and osteopath Stephen Typaldos , who died in 2006 . Originally he called his method orthopathy (as a bridge between orthopedics and osteopathy), later he decided on the name fascia distortion model. Typaldos described recurring patterns in the way the complaints were described in patients with different diagnoses, both in the choice of words and in body language . He suspected that there were six specific “fascia distortions”, ie “disorders within the fasciae of the musculoskeletal system”, which led to reproducible description patterns, since each of the distortions felt different. Trust in people's self-perception is the basis of the new diagnostic method and the basis of every FDM treatment.

Essentially, the diagnosis is based on anamnesis , body language (essential diagnostic tool ) and clinical features , through which trauma is divided into six typical fascial disorders / distortions . The treatment is manual , i.e. by means of specific hand movements.

The six fascial distortions after FDM:

Trigger band
Twisting, splitting or calcification of the (ribbon-like) fascia layer due to incorrect loading
Herniated trigger point
Protrusion of tissue from a deeper tissue layer through an overlying fascia layer "
Continuum distortion
Displacement of the tissue in the transition zone between two different types of tissue such as tendons / bones
Folding distortion
Twisting of the folding fascia on joints, intermuscular septa and interosseous membranes due to tensile or compression forces in connection with rotation. Depending on the course of the twisting, a distinction is made between folding and unfolding distortions.
Cylinder distortion
Overlapping or entanglement of the cylindrical turns of the superficial fascia
Tectonic fixation
Loss of the sliding ability of a fascia surface, as well as the quantity and quality of synovial fluid.

The European FDM Association (EFDMA) was founded in November 2006 in Vienna.
