Painful contractures of the spine and the neck are often due to poor posture, which is sometimes associated with the habit to bend the head forward. This permanent imbalance causes the muscles in the back of the neck to overwork. In this way tensions are created and these bring about stiffness which in the long run causes the typical neck pains also responsible for headaches and other illnesses
The Prof. Dal Monte "Muscle Relaxant" device has the function –as its name says – to reduce and then relieve the state of muscular tightness which so frequently occurs in people, either because of a pathological condition or posture imbalance concerning the cervical part of the spine. This device works by modifying the system of levers – made up of the vertebrae placed one upon the other - whose task is to keep the neck in perfect balance with the head. Therefore it allows to eliminate the work done by the muscles which, after years of strain, are finally free to relax. As a result, neck pain is relieved and our health generally gets much better.
As shown in pictures illustrated hereafter, the centre of gravity of the whole head has a forward position compared to the balancing point based on the spine. This forward position is necessarily counterbalanced by our neck muscles – approximately twenty – which, in accordance with the laws of physics, present an extremely reduced lever arm, which forces them to work through a mechanically unfavourable system of levers.
Consequently the application of a system of weights onto the back of the neck enables the lever arm to extend and to counterbalance the bending forward of the head, thus removing the strain on the neck muscles completely.
Paradoxically, with the application of a counterweight gauged in such a way as to totally remove the tension on the muscles balancing the head on our spine, it is possible to reduce the pressure, instead of increasing it.
The picture to the left, outlines the distribution of the neck muscles, summing up all the elements which intervene in balancing our head on the cervical spin.
BCT: centre of gravity of the head.
BCTC: centre of gravity of head and neck together.
A: this oblique vector makes up the resultant of the force exerted by the various groups of muscles inserted in the upper part of the skull facing down and forward.
B: this oblique vector makes up the resultant of the force exerted by the numerous muscles placed behind the point of where the skull is joined to the cervical spine.
C: point where the skull sets on the neck.
D: this indicates the strain of the muscles balancing the head on the neck.
With the application of the relaxant system, it is therefore possible to considerably reduce the weight put on the intervertebral discs and consequently to prevent the risks of pain caused by the irritation or compression of the nerves originating from the spine.
The picture on the right illustrates the intensity of the vectors showing how the forces exerted by the muscles to keep our head in balance work. The picture on the left, the small purple arrow shows the vector which, thanks to the muscle relaxant system, is needed to keep the head in balance on the neck.
In order to better define the “weight” which keeps our head in the upright position we have chosen to reproduce, with the help of a ballasted skeleton, the muscular forces which have the task to keep our head in balance. Let’s put side by side the two kinds of weights to be compared: on the left hand side we have the natural weights, i.e. those represented by the muscles, and on the right hand side we have the effect of the "balancing weight".
Similarly, in the pictures below, the representation of the skeleton on the right shows the working of the muscles which actually keep the head in balance, whereas in the representation on the right the working of the balancing system is shown. As it has been explained before, the pictures on the left show (as represented by leaden weights) the mechanic work of the weights which actually, that is in the human being, keep the balance of the head. In the photographs on the right, it is possible to notice that, through the use of muscle relaxant device balancing system, the leaden weight is remarkably reduced and it is capable of replacing the work of the muscles entirely. Indeed in the back of our spine there is a great quantity of muscles useful to keep the head in balance on the neck.
We should now outline briefly, in picture aside, how these muscular structures are arranged. The pictures show the successive layers of these muscles, ranging from the very small muscles binding single vertebrae to each other, to the longer ones originating from the occipital area of the skull which, by overlapping the others, extend to be fixed to the ribs. Finally the muscles located closer to the surface are shown: they are just beneath the skin or the subcutaneous tissue.
If the device is used for a short period of time, its effects will be poor because it is not possible to start that progressive physiological adjustment through which the neck muscular system “realizes” that it is no longer necessary to contract the neck back muscles located behind the fulcrum in order to keep the head in balance.
If on the contrary the use of the muscle relaxant device (which can be disguised in different forms: baseball cap, headband, visor or flat hat) is prolonged every day, for as long as it is possible, the relaxant effect will be progressively obtained until the head keeps its perfect balance without contracting the muscles.
Later then, while experiments were being carried out, it was found out that the relaxant effect is felt for a long span of time because of a sort of "memory effect", as it was proved by the experimental research accomplished at the Polytechnic University Institute of Milan, at the University of Udine and at the "Foro Italico" University of Rome.
