HIGH FREQUENCY: ELECTRICAL CAPACITIVE TRANSFERENCE (ECT) AND ULTRA HIGH FREQUENCY (UHF) ELECTROPHYSICAL AGENTS Grade of Physiotherapy San Pablo-CEU University 2023-2024 OUTLINE ELECTRICAL CAPACITIVE TRANSFERENCE 1. ECT THERAPY - NEED CREAM TO APPLY Physiological Effects. Electrodes. 2 Treatment’s protocol. Dosage Contraindications. TECAR THERAPY Ultra high frequency 2. UHF THERAPY - Characteristics. 2 ELECTRIC CAPACITIVE TRANSFERENCE (ECT) • High Frequency Current (0’448 MHz) • Electric Capacitive Transference • Electric Resistive Transference • Direct contact: Current passes through tissues and deepens completely (conductive cream) PUT OVER BOTH ELECTRODES • Electrodes: • Active: Therapist hand (manual therapy) • Neutral: Passive (lumbar or limb) PASSIVE, USED TO CLOSE THE CIRCUIT ACTIVE 3 PHYSIOLOGICAL EFFECTS • 1 INCREASES MICROCIRCULATION: • Without thermal effect, Bioenergetic effect (MECHANIC EFFECT FOR ANKLE SPRAIN) • Acute conditions • Facilitates the drain of liquids. • 2 CAPILLARY AND PRECAPILLARY VASODILATION: • Thermal effect (oxygen and nutrients increase): comfortable heat • Extra oxygen in subacute and muscle conditions but never in muscle’s tear. • 3 HYPERTHERMIA (tolerance level): • Thermal effect is very important. • Metabolism is increased, no pain, no burn. • Chronic conditions (no acute), fibrosis, keloids, capsulitis 4 ELECTRODES • CAPACITIVE: • • Soft-tissues, high water-content and superficial tissues, A CAGE AND IS NOT IN more conductive tissues. Passive treatment. HAS DIRECT CONTACT RESISTIVE: • HAS NO CAGE, ONLY METAL Osteo-articular tissues, less water-content, less conductive tissues. Active treatment (Manual Therapy) FOR DEEPER STRUCTURES, USED WITH STRETCHING BONE SUPERFICIAL BONE DEEP 5 CAPACITIVE SYSTEM INSULATED MATERIAL CERAMIZED ACTIVE ELECTRODE SOFT TISSUES BONE NEUTRAL ELECTRODE ELECTROLYSIS UNDER THE ACTIVE ELECTRODE; NO MATTER WHERE THE NEUTRAL ELECTRODE IS 6 CAPACITIVE SYSTEM BONE 7 ELECTRODES • CAPACITIVE: • Increase electrical energy closed to the active electrode. • Soft tissues: • muscle, • Fluid tissues: venous-lymphatic system. • High water-content and superficial tissues. 8 ELECTRODES • CAPACITIVE: • Passive Treatment (massage to release tension and increase movement) • Superficial muscles • Edema • Muscle Fibrosis • Muscle spasm • Pain • Edema 9 RESISTIVE SYSTEM METALIC NO ISOLATED ACTIVE ELECTRODE SOFT TISSUE BONE NEUTRAL ELECTRODE ELECTROLYSIS BETWEEN ELECTRODES; WORK WITH BOTH ELECTRODES; NEUTRAL ELECTRODE OVER TARGET AREA 10 11 RESISTIVE SYSTEM 12 ELECTRODES • RESISTIVE: • Osteoarticular tissues • Bone • Cartilage • Tendon • Ligament • Fibrosis • MTP • Elongated-contracted tissue • Less water-content (resistance is increased). • Active treatment with Manual Therapy 13 TREATMENT’S PROTOCOL CAN LAST UP TO 40MIN BUT CAN ALSO BE LESS • • • 1ST. CAPACITIVE TREATMENT (10-15 minutes). • Initial heating to prepare tissues. • Vasodilation in surrounding muscles. 2ND. RESISTIVE TREATMENT (10-15 minutes). CHANGE ELECTRODES • Combined with Manual Therapy (passive or active mobilizations, stretchings) • Fixed electrode and less power. 3RD. LOW ENERGY CAPACITIVE TREATMENT (5-10 minutes). • Like 1st phase, buy without thermal feeling • Drainage, cool down. 14 TREATMENT PROTOCOL 15 DOSAGE CAPACITIVE RESISTIVE STATIC MEDIUM SIZE ELECTRODE BIG SIZE ELECTRODE DYNAMIC SMALL SIZE ELECTRODE STATIC DYNAMIC -------------- -------------- DRAINAGE -------------- 5-12% MICROCIRCULATION -------------- 15-20% 3% 5% VASODILATION -------------- 40% 10% 20% HYPERTERMY -------------- 70% 20% 40% DRAINAGE -------------- 5-12% -------------- -------------- 10% 15% BIG SIZE ELECTRODE MICROCIRCULATION -------------- 30% VASODILATION -------------- 60% 30% 40% HYPERTERMY -------------- 100% 50% 100% PROTOCOL TREATMENT: CAPACITIVO-RESISTIVE-CAPACITIVE LAST CAPACITIVE APPLICATION LOOKS FOR A FINAL DRAINAGE AND COOLING TO AVOID RESIDUAL PAIN: 5-9%. IF THERE IS NO CORRECT CONTACT, INCREASE UP TO 12% (MAXIMUM) Microcirculation Tension 0-30% Scale from 0 to 10 2/3 Vasodilation 30-60% 4/7 Hyperthermia 60-100% 8/10 Sensation Seems to feel/Maybe I feel/ Slightly Comfortable/good/right If you stop, it burns/ intense heat/ it boils 16 CONTRAINDICATIONS • • Total: • Pacemakers. • Pregnancy. Relative: • Thermal sensitivity disorders. • Pain sensitivity disorders. • No hyperthermia in visceral disorders(ulcers, inflammations), (reduce temperature). • Menstruation. • Small osteosynthesis material, staples (check contact) • No contraindication in tumours (Ministry of Health) 17 ULTRA HIGH FREQUENCY (UHF) • • • • • Ultra High Frecuency 434 MHz. λ=69 cm. Non-contact therapy. Thermal effects like high frequency currents. • More deeper therapy 18 UHF- DEEPENING SWD: 1’6 cm without  skin temperature MWD: 1’85 cm with important  skin temperature (up to 45º). UHF: 1-6 cm without  skin temperature 19 UHF PHYSIOLOGICAL EFFECTS • TEMPERATURE INCREASE IN TARGET TISSUES: • INCREASE TISSUE METABOLISM TO ENABLE DEGENERATIVE PROCESSES RESOLUTION • ARTERIAL AND VENOUS INCREASE • TO IMPROVE TISSUE’S TROPHISM • TO REDUCE PAIN • TO RELAX MUSCLES • TO IMPROVE COLLAGEN’S ELASTICITY 20 CONCLUSIONS • HIGH FREQUENCY APPLICATION include new treatments for treating deeper structures. Electrical çapacitive transference • ECT uses the combination of high frequency with manual therapy. • UHF heats tissues up to 6 cm. 21 BIBLIOGRAPHY • Zauner Gutmann A.
