Introduction, Indications, Contraindications

1. PULSED SWD P/B:- DR NIYATI PATEL 1

2. Introduction PSWD is referred to as pulsed electromagnetic energy (PEME) OR FIELD DIAPULSE ETC It is created by simply interrupting the output of continuous short wave diathermy at regular intervals. The frequency of pulsed swd is same as that of continuous swd . Frequency 27.12 MHZ but inter pulse interval or off time is added to it. Pulse frequency is between 25 and 600 pps , Pulse width is between 20 and 40 ms (65 ms is most commonly used) P/B:- DR NIYATI PATEL 2

3. By adding rest period to the treatment, the average power is considerably reduced. The heat developed in the tissues is dispersed by the circulation and treatment is thus referred to as non thermal treatment . PSWD Increase the cellular activities, Increases the reabsorption of hematoma, Reduces inflammation, Reduces swelling, Increase repair process. The treatment duration varies from 15 to 60 minutes P/B:- DR NIYATI PATEL 3

4. Indications Effects on inflammation Effects on bacterial infections Relief of pain Effects on muscle tissue Traumatic conditions Reducing healing time P/B:- DR NIYATI PATEL 4

5. CONTRAINDICATIONS Open wound / hemorrhage Metal implant Sensory disturbance Venous thrombosis Arterial disease Menstruation Pregnancy Tumors Deep x ray/cobalt therapy Children Mentally retarded patient Unconscious pt Epileptic pt Uncooperative pt P/B:- DR NIYATI PATEL 5

6. THANK YOU P/B:- DR NIYATI PATEL 6

7. LONG WAVE DIATHERMY LWD is the use of high frequency electromagnetic waves of the frequency 1MHZ and wavelength 300m. LWD SWD FREQUENCY 1MHZ 27.12MHZ POWER OUTPUT 25-75 Watts 250-1000 Watts P/B:- DR NIYATI PATEL 7

8. SWD , LWD does not produce any interference with other equipment. INDICATIONS Same as MWD Metal implantation CONTRAINDICATIONS Same as MWD Except metal implant Portability & affordability of equipment is good in LWD as compared to SWD P/B:- DR NIYATI PATEL 8
