“…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

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.

“…Further, although CARE therapy is delivered in a static mode, it has a substantial muscle-relaxing effect, which facilitates shoulder rehabilitative exercises. 5,6 In particular, the use of static electrodes avoids the bias caused by differences in operator skill and training. The massage that the therapist performs with the hand piece in classical diathermy renders the treatment operator-dependent, which may cause bias.…”

“…2,3 Bito et al 4 reported that CARE substantially improves blood circulation in the peritendinous region and increases haemoglobin saturation. In addition, CARE therapy warms deep tissue; 5 the resulting greater vascularization promotes the relaxation of tissues (especially muscular tissue) and drainage of swelling (oedema and haematoma).…”

Effects of capacitive and resistive electric transfer therapy in patients with painful shoulder impingement syndrome: a comparative study

Objective Capacitive and resistive electric transfer therapy (CARE) reduces pain and improves quality of life for many orthopaedic degenerative and inflammatory disorders. The research aim was to determine the effects of CARE on painful shoulder. The outcomes were pain reduction and recovery of shoulder function. Methods A retrospective, observational case-control study was conducted. Participants were 46 patients (22 in the CARE group and 24 in the SHAM group). Clinical data, pain (visual analogic scale, VAS) and functional scale scores (Disabilities of the Arm, Shoulder and Hand scale, and Constant–Murley Scale) were measured at baseline T0 (before treatment), T1 (after treatment) and follow-up T2 (2 months after the end of the treatment). Results VAS scores in the CARE group improved from 7.23 ± 1.11 at baseline to 2.68 ± 0.99 at follow-up. The SHAM group did not experience any improvement. Similarly, functional scale scores improved in the CARE group compared with the SHAM group. Conclusion Considering the small number of sessions needed, low cost and long-term benefits, CARE could be a useful therapeutic option for the conservative management of shoulder pain to restore pain-free and powerful movement to the shoulder joint.

Aim To evaluate the efficacy of adjuvant, capacitive resistive monopolar radiofrequency (CRMRF, INDIBA) treatment at 448 kHz together with physiotherapeutic techniques compared to a sham treatment with the same techniques, for pain reduction and quality of life (QoL) improvements in patients with chronic pelvic pain syndrome (CPPS). Methods A triple‐blind, randomized controlled trial (RCT) including patients with CPPS randomly allocated (1:1) to a CRMRF‐activated group (intervention) or a CRMRF‐deactivated one (control). Both groups received physiotherapeutic techniques and pain education weekly for 10 consecutive weeks. Data from a visual analogical scale and the SF‐12 questionnaire were collected at trial commencement and repeated at the 5th and 10th sessions. Pain intensity was considered the main outcome. For the comparisons between variables, the χ2 and Student's t test were used. Superiority was analyzed by estimating the mean change (95% confidence interval). Analysis was performed for the per‐protocol and the intention‐to‐treat populations. The statistical significance level was set at p < 0.05. Results Eighty‐one patients were included (67.9% women) with a mean age of 43.6 years (SD 12.9). CRMRF lessened pain scores by more than 2 points and improved QoL by 5 points. There were no relevant side effects and overall adherence to the treatment was 86.4%. Conclusions This is the first RCT that evaluates the efficacy of CRMRF (INDIBA) compared to a sham treatment, and demonstrates its superiority in decreasing pain and improving QoL. Such results may lead to greater prescribing of CRMRF when treating CPPS patients.
