Uvod: Kapacitivni in uporovni prenos energije v radio-frekvenčnem spektru, približno 0,5 MHz, se uporablja za globinsko ogrevanje tkiva. V literaturi se pogosto navaja s kratico TECAR (špa. Transferencia Eléctrica Capacitive Resistive). Kljub vse pogostejši uporabi terapije v rehabilitaciji, so razlike v termičnih učinkih kapacitivne in uporovne modalitete še vedno slabo raziskane. Namen: Primerjati termične učinke kapacitivne in uporovne modalitete na spremembo temperature kože ter preveriti vpliv debeline kožne gube in uporabljene moči aparature na povišanje temperature kože. Metode dela: Izveden je bil randomiziran nadzorovan poskus z navzkrižnim raziskovalnim protokolom, v katerem je sodelovalo 31 zdravih odraslih. Vsi preiskovanci so prejeli aktivno in placebo kapacitivno in uporovno terapijo. Debelina kožne gube je bila izmerjena s kaliperjem. Meritve temperature kože so bile opravljene z infrardečo kamero pred terapijo, po 10-minutni terapiji in 30 minut po terapiji. Intenzivnost terapije je bila določena glede na subjektivni občutek zaznave toplote preiskovancev in na koncu zabeležena uporabljena moč aparature. Za analizo rezultatov so bili opravljeni t-test za en vzorec, odvisni t-testi in linearna regresija. Rezultati: 10-minutni terapiji s kapacitivno in uporovno modaliteto sta statistično značilno in klinično pomembno povišali temperaturo kože. Kapacitivna modaliteta je bila pri tem učinkovitejša. Obe modaliteti sta bili učinkovitejši od placebo terapij. Temperatura kože je ostala statistično značilno povišana tudi 30 minut po terapiji ne glede na modaliteto. Razlik v poznejših termičnih učinkih med kapacitivno in uporovno modaliteto ni bilo. Rezultati so pokazali, da obstaja linearna povezanost med spremembo temperature kože in debelino kožne gube ter uporabljeno močjo aparature le pri kapacitivni modaliteti. Razprava in zaključek: Obe modaliteti sta učinkoviti pri zvišanju temperature kože, ki ostane povišana tudi 30 minut po terapiji. Prvi vpogled in ugotovitve o vplivu drugih dejavnikov na termične učinke nakazuje različno porazdelitev termičnih učinkov med kapacitivno in uporovno modaliteto, kot je opisano v literaturi. Potrebne so dodatne raziskave, ki bi primerjale tudi druge učinke med modalitetama, vendar je za primerjavo pomembno upoštevati uporabljeno moč ali dovedeno energijo.

Introduction: Capacitive and resistive energy transfer uses radiofrequency of approximately 0,5 MHz and is used for deep tissue heating. In the literature, this therapy is commonly referred to as TECAR (Span. Transferencia Eléctrica Capacitive Resistive). Despite the increasing use of this type of therapy in rehabilitation, the differences between capacitive and resistive modalities are still poorly researched. Purpose: To compare thermal effects of capacitive and resistive modalities on skin temperature changes and to investigate the influence of skinfold thickness and applied power of the device on skin temperature increase. Methods: A randomized controlled crossover study was conducted, in which 31 healthy participants participated. They received active and placebo capacitive and resistive therapy. The thickness of skinfold was measured with skinfold caliper. Skin temperature was measured with infrared thermography before therapy, immediately after ten-minute treatment and 30 minutes after. Therapy intensity was adjusted based on the participant’s subjective perception of heat. The device power in treatment was recorded. One-sample t-tests, paired t-tests and linear regression analyses were performed for data analysis. Results: The increase in skin temperatures after ten minute capacitive and ten-minute resistive therapy were statistically and clinically significant. Capacitive modality demonstrated greater effect. Both modalities were more effective than placebo therapies. Skin temperatures remained significantly elevated compared to before treatment in both modalities. No difference between modalities in delayed thermal effects were observed. The results showed linear association between skin temperature change and skinfold thickness and applied power only for capacitive modality. Discussion and conclusion: Both modalities were effective in increasing skin temperature that remained also 30 minutes after the treatment. First insights into the influence of other factors in reaching thermal effects suggest a different distribution of thermal effects in capacitive compared to resistive modality, as described in the literature. Further studies comparing other effects between modalities are needed. Applied power or delivered energy during therapy should be considered when comparing the two modalities.
