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 Learn how to manipulate the SWD unit taking into consideration the technique of application, equipment, precautions and contraindications and tx parameters Diathermy : Diathermy When radiofrequency EM energy of sufficient intensity directed at biological tissues will cause heating 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 Method : Condenser Field Method Utilizes the ELECTROSTATIC FIELD Superficial heating 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 greatest resistance or least conductivity Coplanar Positioning Plates are in PARALLEL Greatest heating: least resistance/great conductivity Crossfire Application For treatment of sinuses, thorax, pelvis and uterine disorders Induction Field Method : Induction Field Method Utilizes the ELECTROMAGNETIC FIELD Deeper heating Generates magnetically induced EDDY CURRENTS in water-rich tissues Types of electrode Diplode/drum Monode Minode Coil electrode Creates practically NO heat in the fatty layer and MOST of the heat is created in muscle where it can do the most good Factors Influencing Field Distribution in SWD : Factors Influencing Field Distribution in SWD Spacing Decreased: superficial heating Metal Air Electrode Size Small electrodes: superficial heating Therapeutic Effects of SWD : Therapeutic Effects of SWD Reduce pain and inflammation Reduce muscle spasm Increase blood flow Increase enzymatic activities Increase metabolism Increase ROM Increase elasticity of connective tissue Contraindications : Contraindications Metal implants Pregnancy Malignancy Cardiac pacemakers Ischemia or atherosclerosis Active bleeding Open wounds, skin lesions in tx area Acute infection/fever Precautions : Precautions Px with: Hearing aids Contact lens Electrophysiological orthoses Keep transistorized units at least 5-10 feet away from the SWD machine Pulsed Shortwave Diathermy : Pulsed Shortwave Diathermy Pulse Freq Range: 15-200 Hz pd: 0.4 ms Metal is NOT an absolute contraindication Adv: effective in tx of post-traumatic cond D/A: expensive Slide 16: The end Curapuls 419 : Curapuls 419 Two modes of therapy: Continuous subjective feeling of warmth Max output: 400 W Automatic tuning ensures that the selected intensity is maintained throughout tx Effects: increase circulation stimulates metabolic processes Pulsed Athermic technique with enhanced biological effects.
