Clinical Trial Summary
Physical therapies based on electrical or electromagnetic stimulation have been used in
rehabilitation, in some cases combining electrical therapy with radiofrequency. Specifically,
resistive capacitive electrical transfer therapy (CRet) has been used in physical
rehabilitation and sports medicine to treat muscle, bone, ligament and tendon injuries. CRet
is a non-invasive electrothermal therapy classified as deep thermotherapy, which is based on
the application of electrical currents within the radiofrequency range of 300 kHz - 1.2 MHz.
While the heat conducted by surface thermotherapy cannot reach the muscle due to the
electrical resistance of the tissues, the capacitive-resistive electrical currents in CRet
therapy can generate heating of deep muscle tissues, which in turn improves haemoglobin
saturation. In Europe, CRet is widely used in various medical rehabilitation processes. The
physiological effects of this type of physiotherapy are generated by the application of an
electromagnetic field with a frequency of approximately 0.5 MHz to the human body. The
effects attributed to this technique include increased deep and superficial blood
circulation, vasodilatation, increased temperature, removal of excess fluid and increased
cell proliferation.
Some of these reactions, such as increased blood perfusion, are known to be related to the
increase in temperature, but others, such as increased cell proliferation, appear to be
primarily related to the passage of current.
It is also true that this increase in tissue temperature, generated through the application
of the device, is a physical reaction to the passage of current (Joule effect). Although
there is already clinical literature supporting this mechanism, the amount of energy and
current that must be transferred to obtain the desired temperature rise is unknown. Moreover,
the control of these reactions, by adjusting parameters such as absorbed power and electrode
position, is still largely based on the empirical experience of therapists .
Recently, new cadaveric publications have been generated, which support the mechanisms of
current flow and thermal changes in this situation.
Against this background, in which thermal effects, current passage and symptomatic
improvements have been demonstrated in patients with pathology, the possibility that these
treatments may improve functional sporting abilities is raised. This hypothesis arises from
the fact that current flow and thermal changes have been directly related to viscoelastic
changes in capsular and muscle tissue.
To date, there is no study that has assessed whether this therapy generates any change in
functional variables related to sports performance in professional athletes.
