Traditional braces or orthoses are made in order to block the wrist in a "neutral" position because this position avoids further compressing the median nerve, a compression that would worsen the symptoms.


CARPALELLO instead acts in a completely different way: it does not block the wrist, but leaves the hand completely free and acts "actively" right on the Carpal Tunnel.


This action is allowed thanks to the complex bone structure of the wrist and hand joint.




Carpal Tunnel Syndrome is due to the compression of the Median Nerve, an important mixed nerve whose function is to deal with the transmission of both motor and sensory information.


The Median nerve flows along the entire arm and once crossed the wrist area branches into three arms in the relative first three fingers of the hand.


The area of interest that affects the syndrome is located where the Median Nerve crosses the wrist, passing through a cavity called Carpal Tunnel, a cavity formed at the base by the bones of the wrist and covered by the Transverse Carpal Ligament.


In the same cavity also nine Flexor Tendons flow, which take care of flexing the fingers of the hand.


The tendons are covered by a membrane called the Synovial Sheath, which also contains a fluid called the Synovial Fluid, these both have nourishing and lubricating functions that allow sliding.

CTS Carpal Tunnel Syndrome occurs when the Median Nerve undergoes compression inside the Carpal Tunnel, and it is a phenomenon mainly due to the enlargement of the Flexor Tendons, caused in turn by an excess of Synovial Fluid.

The excess of synovial fluids is mainly due to hormonal changes (and that's why this syndrome affects women more than men), but it can be the consequence of excessive or posturally incorrect use of the hand. In fact, the continuous flow of tendons following recurring and repeated movements leads to a local rise in temperature due to friction.


As a consequence, other synovial liquids are recalled, which in addition to providing mechanical lubrication function, also perform the heat exchange function facilitating the disposal of heat.


The Carpal Tunnel is a rather narrow cavity, so when the Flexor Tendons begin to increase in volume, it is inevitable that at a certain point the Median Nerve is compressed, generating the birth of the Carpal Tunnel Syndrome.

The Carpalello solution comes from the idea of ​​acting with a combination of forces and pressures on the Metacarpal bones, generating a slight displacement of the Carpal bones within the wrist.  This is based primarily on the biomechanical study of the complex articulation of the hand and wrist, which sees the metacarpal bones in close connection with the carpal bones of the wrist (natural state of the Carpal Tunnel), and the extreme mobility of the carpal bones which the attached video describes the kinematics.


Following the study, device prototypes were developed tested and improved on people affected by the disease, hence the birth of the device which was patented and later called CARPALELLO.


The movement of the wrist bones induced by the device is able to slightly increase the space inside the carpal tunnel without contraindications, giving the possibility to the median nerve to decompress.


The first effect of this intervention, perceptible quickly enough, is the attenuation if not the disappearance of the symptoms.


The second longer-term effect is to facilitate the reabsorption of excess fluids accumulated in the tendons.

This is due to a mechanical factor, because wearing Carpalello at rest in a horizontal position with a relaxed hand, physically "opens" the passage of fluids which, due to the difference in pressure between the hand and arm areas, tend to migrate and be reabsorbed restoring normal physiological condition.


There is another aspect under study and scientific development for future confirmation, formulated by the inventor of Carpalello who continues in the observation of the effects and in-depth scientific analysis on the topic: the median nerve is a sensory nerve (so much so that when it is compressed in the carpal tunnel, discomfort is felt in the areas of the hand where it branches out) and communicates its "discomfort" to the nervous system.

The same nervous system, in response to the request for help from the suffering nerve, responds by "sending" additional fluids to facilitate the disposal of excess heat and lubrication, but doing in this way it worsens the situation, and icreases the severity of the syndrome.

Thanks to the mechanical action of Carpalello, instead, the median nerve is decompressed and therefore does not send signals of discomfort to the nervous system so this phenomenon is not triggered, while the absorption of excess current is facilitated.
