1. Books of Mechanical Link



Dissatisfied with the inconsistent results obtained with their patients when using usual osteopathic diagnostic and treatment methods, the two authors have undertaken research in order to become more efficient.

As a result of their work, they have re-examined the basic osteopathic concept while keeping to A.T. Still’s fundamental principle: “structure governs function”, as structure is the osteopathic mechanical link i.e. connective tissue in all its forms.

Thus this book suggests, for the first time, a scientific approach to this connective tissue (including bone).  From its anatomy, its histology and its relationships with other tissue in the body, precise physiology, biomechanics and physiopathology are drawn that explain a number of symptoms, as well as diseases.

From the very particular properties of this connective tissue derives a simple and reliable clinical examination method that uncovers the biomechanical causes of the symptoms presented by a patient, anywhere in the body.  These properties also lead to choosing the best possible treatment for each patient, whether allopathic, homeopathic, acupunctural or osteopathic.  In the latter case, the technique employed will have to be physiological, therefore in keeping with the caracteristics of connective tissue.

FOREWORD                    ORDER




Le Lien Mécanique est une méthode ostéopathique innovante qui propose, pour le diagnostic et l’ajustement, un ensemble de techniques spécifiques.

Ainsi les tests de mise en tension permettent d’examiner avec simplicité la totalité du corps et de mettre en évidence l’ensemble des lésions existantes. Les tests en balance permettent de hiérarchiser avec logique ces lésions afin d’en dégager les dominantes et la primaire.

Ce système diagnostique a rendu possible l’exploration de champs anatomiques jusqu’alors négligés et de découvrir des lésions ostéopathiques méconnues : le diastasis articulaire, la fixation des lignes de force intra-osseuses ou la lésion de l’artère jouent par exemple un rôle étiopathologique considérable dans beaucoup de cas. Le fait de connaître ces lésions, de savoir les tester et les traiter constitue une grande avancée en thérapie manuelle. Au niveau du traitement, la technique originale du recoil permet une correction rapide et efficace des lésions primaire et dominantes afin de normaliser, directement ou indirectement, toutes les lésions existantes. Cette technique est sans contre-indication chez l’ensemble des patients.

Cet ouvrage expose de façon claire et détaillée la méthodologie du Lien Mécanique. C’est un ouvrage totalement nouveau qui fait suite à une première présentation de la méthode en 1985. Cette édition française est à l’origine de l’édition américaine (Mechanical Link, 2002).

INTRODUCTION                    ORDER




Arteries are essential structures, vital and omnipresent with surprisingly important functions. Their roles include those which are well-knowm, such as providing nutrition to tissues. There are some functions which are often underestimated and overlooked. Arteries also serve as conduits for information to the autonomic nervous system as well as providing biomechanical function of the extremities, spine and the viscero-organic system.

In fact, the vascular system along with its accompanying autonomic nervous system unite the whole body and provide the osteopath with "the link" which is simultaneously fluid, mechanical and neurological.

This publications is the result of 15 years of work and clinical practice by the authors. Their work makes a complete manual approach to examination and treatment of the vascular system possible.

Undeniably, this osteopathic approach to examination and treatment of arteries offers new perspectives to traditional medicine. This work serves as a clear and didactic reference to allow our readers to finally access a means of putting the original concept proposed by A.T. Still : " The rule of the artery is supreme ".

At last, here is an innovative book about osteopathy. Despite Andrew Taylor Still's obvious interest in the osseous system, his successors failed to expand the concept of intra-osseous lesions. This unfortunate void concerning the concept of global lesion has however been filled.

The different osseous dysfunctions which we have presented in this work have never been described nor recorded in osteopathic terminology. This knowledge is of great interest for osteopathy as well as orthopedic medicine and athletics so often confronted with painful symptomatology without explanation or therapeutic response. With the information presented in this book, you will not only discover the importance and diversity of these intra-osseous lesions, but you will also learn to test and correct them in a simple, rapid and effective way. One whole chapter is devoted to the articular diastasis and finally offers an osteopathic solution to the particular problem of joint instability and hypermobility.

FOREWORD                    ORDER




The authors are French osteopaths who are world renowned for the quality of their teaching, and in this book they present an entirely novel approach of the peripheral nervous system based on a rapid and precise diagnosis of the critical points to be treated.

The book exposes in an educational manner the etiology of osteopathic nerve lesions and their correlation with major points of acupuncture, and gives detailled descriptions of each of the principal key points of the peripheral nervous system as well as their clinical correlations with a number of functional pathologies, that may or may not be symptomatic. The quality of the artwork, which includes over 200 originals illustrations-drawings, dissections and photographs by the authors-clearly displays the anatomy of nerves as well as the best way to approach to the nervous system. An entire chapter has been devoted to the encephalon and the new osteopathic treatment perspectives in this field, completing this book as a reference on the manual approach to the nervous system.

This book is intended for all osteopaths and health professionals who wish to broaden their horizons by integrating in a simple but efficient way the evaluation and treatment of "the neurological lik" into their practice.

2. Memoirs dealing with the Osteopathic Mechanical Link



This study has been carried out with the aim of knowing if the recoil technique can cure or relieve patients who suffer from metatarsalgia.
Thirty-one people presenting metatarsalgia took part in the protocol. They were interrogated about the density, the course and the localization of their pain. First we took the footprint thanks to an electronic podoscope followed by an osteopathic manipulation (tests and corrections). We took a new footprint at the end of the session.

We met the patient three weeks later in order to have a feed back on the modification of the intensity of the pain and to take a new footprint. Thanks to this new footprint we could observe the modifications that occurred during the weeks following the manipulation.
If the patient felt no improvements the podiatrist prepared him orthoses. In most cases we noticed that the threshold of the pain had decreased.
Contrary to patients who needed orthoses those who didn’t need orthoses revealed a distinct modification of their footprint just after the manipulation.
Those results confirm our initial assumption. Indeed the application of the recoil technique on the metatarsals turns out to be effective since it contributes to a relief in most cases. This technique permitted some of them to avoid a podologique orthose. Within the framework of a partial improvement it permitted the others to have a less restricting orthose.






The Recoil is a manual technique, sometimes assimilated to the Toggle-Recoil of chiropractors, daily used by osteopaths. If its clinical efficiency is admitted, the way it works, its physiology and mecanism, are not yet well-known. Thus it seemed pertinent to define more precisely this technique in order to understand always better our technical effects on our patients.The main objective of this study is to make an inventory of the knowledge about Recoil so far.
Is the Recoil technique at the intersection of several osteopathic disciplines ?

The literature used is derived from databases, scientific reviews, mainly chiropractics, books of osteopathy and master's thesis.

The recent medical researches about anatomy, neurology, biotensegrity and fascia are also taken into account.

Data were studied and organized in three parts : history of the technique and its principles, its practical application and efficiency, it's modes of action.





Restless Legs Syndrome (RLS) is characterized by the urge to move the legs in the evening and/or at night. This painful disturbance often hinders sleep quality. People have difficulty describing the issue and rarely consult for this reason. Moreover, the patient’s symptoms are often misdiagnosed. The etiology of primary RLS is still controversial as a result of which it is classified as an idiopathic pathology. The hypothesis suggested in this thesis is about that the Filum Terminale (FT) is too tense, inducing excessive Traction Force on the spinal cord, for which an osteopathic treatment is proposed.

Two groups (with and without RLS) of 20 patients were treated by different Osteopathic Mechanical Link practitioners.

We recorded:
- the frequency of positive FT tests in the group of people suffering from RLS, compared to that of the group not suffering from RLS .
- the evolution of symptoms of patients suffering from RLS as a result of a general treatment and a specific correction of the FT according to the OML method.

We have found a strong prevalence of positive FT tests in the case of RLS patients. All the patients treated experienced partial or complete improvement of their symptoms.
When too tense, the FT seems to be involved in primary RLS and the osteopathic treatment we suggest a provided significant relief to all patients.





Osteopathy is able to improve general symptoms of pain or discomfort. We suspected it was true also for lactation problems.
We therefore carried out a comparative intervention study before/after treatment on a cohort of 16 breastfeeding patients from the Lyon region. All of these had lactation problems, such as pain during breastfeeding and/or clogged milk ducts and/or insufficient milk production.

In our memoir, the therapeutic protocol refers to the Lien Mécanique Ostéopathique (“Osteopathic Mechanical Link”), whose only action is the so-called recoil, which we applied by a gentle approach to the breast area.
We found a significant improvement of each item for every mother treated. Thus, osteopathy has a role to play for lactation disorders in the nursing mother.




3. Other collaborations of the teachers of Mechanical Link



They are 27 osteopaths who have expressed themselves on their craft with passion and generosity.

They describe their encounter with osteopathy: vocation or coincidence?

They reveal to us what they find most marvellous in osteopathy: so much beauty!

They share a significant anecdote, for them and for osteopathy: emotion, hope and passion.

They are given the freedom to tell us what matters the most to them: precious advice and a great source of professional inspiration for their readers.

They have passed on a heritage: the authenticity of the osteopathic tradition founded by Andrew Taylor Still, D.O.

They bear witness to the philosophy, the spirit and the art of osteopathy in its original purity and in its modernity.

Edition in English





Osteopaths express themselves in this book.  They try to account for what makes their daily perceptive, relational and therapeutic experience, and to analyze it with philosophical tools.

Each author approaches his subject according to their osteopathic sensibilities while drawing from other authors from philosophical tradition, as well as other academic disciplines.  Thus they contribute in epistemologically founding the practice of osteopathy.

The texts that compose this book were all written by osteopaths as part of the University Diploma « Philosophie de l’ostéopathie » at the Centre Interdisciplinaire d’Éthique of the Université Catholique de Lyon since 2014.

This book is available in French only.
