Effect of Capacitive and Resistive electric transfer on changes in muscle flexibility and lumbopelvic alignment after fatiguing exercise

Abstract

[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.

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

“…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.…”

“…Despite the widespread use of CARE in the rehabilitative field, scientific evidence of its effectiveness for painful shoulder is limited and equivocal. Yokota et al 6 analysed the effects of CARE therapy (15 minutes of intervention) on muscle flexibility and lumbar-pelvic alignment after fatiguing exercise for other pathologies, such as back pain. They found good results for CARE compared with a control (15 minutes of rest).…”

Accelerometric Changes before and after Capacitive Resistive Electric Transfer Therapy in Horses with Thoracolumbar Pain Compared to a SHAM Procedure

“…In addition, this rise in temperature resulted in increased concentrations of oxygenated and total hemoglobin concentrations, which were maintained for at least 30 min after therapy. Later, Yokota et al [14] used the Ely test in twenty-two healthy males to assess the quadriceps muscle flexibility after intense exercise. They observed a significant decrease in the angle of the Ely test (which suggests a decrease in quadriceps flexibility immediately after knee extension exercise), as well as a significant increase in the angle of the anterior pelvic tilt after exercise.…”

Effects of the signal modulation on the response of human fibroblasts to in vitro stimulation with subthermal RF currents

“…Capacitive-resistive electric transfer (CRET) therapies are based on non-invasive application of RF, sinewave electric currents within the 448-600 kHz range, aimed to induce hyperthermia in the treated tissues (Fousekis et al 2020;Grimnes and Martinsen 2000;Kotnik and Miklavcic 2000;López-de-Celis et al 2020). CRET therapies have been reported to be effective in treating bone (Kumaran and Watson 2019), muscle (Ganzit et al 2000;Mondardini et al 1999;Parolo and Honesta 1998;Takahashi et al 1999;Yokota et al 2018), or tendons and ligaments (Bito et al 2019;Costantino et al 2005;Stasinopoulos et al 2020).…”
