Veron, MPH, PTRP Topic Objectives : Topic Objectives Explain the difference between the two techniques of SWD application and its associated electrodes Make a generalization regarding the continuous and pulsed application of SWD Discuss the various clinical applications and indications for using SWD and its physiological effects 4. Learn how to manipulate the SWD unit taking into consideration the technique of application, equipment, precautions and contraindications and the treatment parameters Diathermy : Diathermy “to heat through” deep heating produced by high frequency alternating currents 3 Major Types Longwave Shortwave Microwave Shortwave Diathermy : Shortwave Diathermy Therapeutic freq: 13.56 MHz (22 meters) 27.12 MHz (11 meters) 40.68 MHz (7 meters) Strongest effect: MUSCLE Inc 15°C (subQ) & 4-6°C (muscle) 2 main circuit: Machine/power circuit Resonator/patient circuit Tuner: designed to bring the patient circuit into resonance with the main circuit for effective operation Technique of application: Condenser Field Method Induction Field Method Condenser Field /Electric Field Method : Condenser Field /Electric Field Method Utilizes the ELECTROSTATIC FIELD Max temp occurs in water-poor substances Types of electrode: Capacitor/condenser electrode Flexible/condenser pads Internal metal electrode Strength of field is NOT homogenous Condenser Field Method : Condenser Field Method Distance bet condenser & skin: 25 mm Less divergence of rays in fat as compared to higher fluid content tissues Greatest heating UNDER electrode: subQ Greatest heating BETWEEN electrode: muscle Condenser Field Method : Condenser Field Method Contraplanar/Transverse Positioning Plates are positioned in SERIES Greatest heating occurs in tissues with higher impedance Coplanar Positioning Plates are in PARALLEL Greatest heating: tissues with low impedance Crossfire Application For treatment of sinuses, thorax, pelvis and uterine disorders Induction Field/Magnetic Field Method : Induction Field/Magnetic Field Method Utilizes the ELECTROMAGNETIC FIELD Generates magnetically induced EDDY CURRENTS in water-rich tissues Creates practically NO heat in the fatty layer and MOST of the heat is created in muscle Types of electrode A.
