“…The main underlying mechanism is considered to be the rise in temperature associated with electromagnetic energy, which triggers oscillation and friction forces of charged molecules, such as proteins and ions. This increase in temperature has been described at a superficial level (10-15 mm, which is believed to reflect the state of the subcutaneous adipose tissue and fascia), but also at a deeper level (20-30 mm, which is supposed to reflect the state of the muscle layer) [7,8,13]. The mild elevation of the temperature achieved in these studies was enough to accelerate metabolic activity and to improve local circulation.…”

“…In addition, a summing effect appeared to happen in the second session of CRET in these parameters, since SL was longer on the second day (26, 30 and 36 h after the first session) compared to the first day (2, 6 and 12 h). The duration of the increased temperature and other physiological effects caused by CRET have not been defined exactly, and skin, superficial and deep temperature, blood flow and hemoglobin saturation, have been measured up to only to 30 min post-application [7,8,13]. Moreover, several in vitro studies have shown that CRET application also exerts non-thermal effects, consisting of a modulation of cellular activity and changes in membrane transport [18,19].…”

“…In human beings, physical therapies based on electromagnetic stimulation, specifically, a system of capacitive resistive electric transfer (CRET) has been demonstrated to affect spatiotemporal biomechanical parameters after exercise [6]. CRET delivers radiofrequency energy that passes between active and inactive electrodes, resulting in increased deep (muscle) temperature and blood flow and flexibility and improved hemoglobin saturation [7,8]. Duñabeitia et al [6] considered that these physiological changes would promote a more efficient running pattern, as shown by the lower SF and longer SL reached in their study after application of a CRET session in recreational runners.…”

Capacitive resistive electric transfer modifies gait pattern in horses exercised on a treadmill

et al. 2020

Background: Capacitive resistive electric transfer (CRET), a radiofrequency at 448 kHz, resulted in increased superficial and deep temperature and hemoglobin saturation, faster elimination of metabolic and inflammatory products and enhanced sport performance in humans. This research aims to investigate whether the application of CRET affects the locomotor pattern in horses and to assess whether an accumulative effect appears when two CRET sessions are applied two consecutive days. Methods: Nine horses were subjected to two CRET sessions applied in both right and left sides of neck, shoulder, back and croup. The horses were exercised on a treadmill, at walk and at trot, before CRET application and at 2, 6 and 12 h after. A second CRET session was applied next day, and the animals were evaluated again at the same times (i.e. at 26, 30 and 36 h after the first session). Between 5 and 7 days later, the same horses were subjected to a sham procedure and they were evaluated in the same times as in the CRET experiment. During treadmill exercise, locomotor parameters were measured with a triaxial accelerometer fixed in the pectoral region and in the sacrum midline. Results: The sham procedure did not affect any of the accelerometric variables studied. CRET applications resulted in greater total powers, which resulted in absolute increased dorsoventral, mediolateral and longitudinal powers. However, a reduction in dorsoventral power expressed as a percentage of total power was found. Stride regularity increased. The greater total power resulted in longer stride length and because the velocity was kept fixed on the treadmill, stride frequency decreased. An accumulative effect of CRET application was only found in stride length and frequency. Conclusions: It appears that CRET is a useful technique to enhance power and to elongate the stride at defined walk and trot velocities. The effect of these changes on performance should be studied for horses competing in different sport disciplines.

“…Radiofrequency treatment is a therapeutic approach used in the treatment of most musculoskeletal and sports injuries. One of the most effective radiofrequency treatments is Indiba ® Activ treatment at 448 kHz, a frequency that has been associated with pain reduction and improved functionality in patients with musculoskeletal disorders [2][3][4] . This wavelength promotes ion mobilisation between the intracellular and extracellular matrix and restores cell membrane permeability.…”

This study aimed to evaluate the posterior thigh's skin thermal responses to 448-kHz radiofrequency-based therapy applied either in the form of standard application (Indiba ® Activ) or combined soft tissue treatment (Indiba ® Fascia treatment). [Participants and Methods] Ten healthy males (22 ± 3 years of age, weight 75.2 ± 4.9 kg, height 178.5 ± 4.7) received four different treatments which included a) Indiba ® Activ (IA) radiofrequency treatment, b) Indiba ® Fascia (IF), c) Indiba ® Activ placebo (IAP) and d) Indiba ® Fascia Placebo (IFP) in the posterior thigh of their dominant lower limb, while the non-dominant served as the control. Skin temperature was recorded pre-and post-treatment and every minute until the surface temperature reached pre-treatment levels using a wireless infrared thermometer. [Results] Both radiofrequency-based therapy groups IA and IF led to a significant increase in skin temperature compared to placebo applications. The IF intervention led to an average retention of elevated temperature for 164.2 minutes compared to 54.8 minutes of IA, 23.17 of IFP and 17.6 minutes of IAP. [Conclusion] These findings indicate that radiofrequency treatment at 448 kHz can induce and sustain significant thermal skin adaptations reflecting an increased blood circulation and metabolism of underlying tissues.

[Purpose] This study aimed to clarify the effects of Capacitive and Resistive electric transfer (CRet) on changes in muscle flexibility and lumbopelvic alignment after fatiguing exercise. [Subjects and Methods] Twenty-two healthy males were assigned into either the CRet (n=11) or control (n=11) group. Fatiguing exercise and CRet intervention were applied at the quadriceps muscle of the participants’ dominant legs. The Ely test, pelvic tilt, lumbar lordosis, and superficial temperature were measured before and after exercise and for 30 minutes after intervention. Statistical analysis was performed using one-way analysis of variance, with Tukey’s post-hoc multiple comparison test to clarify within-group changes and Student’s t-test to clarify between-group differences. [Results] The Ely test and pelvic tilt were significantly different in both groups after exercise, but there was no difference in the CRet group after intervention. Superficial temperature significantly increased in the CRet group for 30 minutes after intervention, in contrast to after the exercise and intervention in the control group. There was no significant between-group difference at any timepoint, except in superficial temperature. [Conclusion] CRet could effectively improve muscle flexibility and lumbopelvic alignment after fatiguing exercise.
