Shortwave Diathermy Chapter 9

Slide 2

Description High-recurrence electrical streams Radio waves Pass through the tissues Cause atomic vibration Results in profound warming Capable of warming huge volumes of tissues Causes both warm and nonthermal impacts

Slide 3

Thermal Effects Deep warmth Increased blood stream Increased cell digestion system Increased tissue extensibility Muscular unwinding Possible changes in protein responses Nonthermal Effects Edema lessening Lymphedema diminishment Superficial injury mending Treatment of venous stasis ulcers Uses

Slide 4

Types of Shortwave Diathermy Induction Field Capacitive Field

Slide 5

Induction Field Diathermy Places the patient in the electromagnetic field Selectively warms muscle Also alluded to as: Condenser field diathermy Magnetic field diathermy

Slide 6

Induction Field Diathermy (Cont.) A curl is housed inside a drum Current streaming inside the loop delivers a pivoting attractive field Magnetic field produces vortex ebbs and flows in the tissues Eddy ebbs and flows cause rubbing that produce heat Although uncommon, links are now and then utilized as a part of spot of drums

Slide 7

Capacitive Field Diathermy Uses the patient's tissues as a part of the circuit The tissues' electrical resistance produces warm Selectively warms skin Muscle is warmed by means of conduction from the fat Also alluded to as "condenser field diathermy"

Slide 8

Capacitive Field Diathermy (Cont.) Heat is created by the dipole impact Charge particles inside film adjust to the field The development produces heat + - + - + - + - + -

Slide 9

Modes of Application Continuous Increases tissue temperature Increased danger of smolders Pulsed May or may not build temperature Pulses take into account expanded treatment power and length Not the same as "nonthermal"

Slide 10

Ultrasound & SWD Comparison Ultrasound Shortwave Diathermy Energy type Acoustical Electromagnetic Tissue heated Collage-rich C: Skin, fat tissue I: Muscle, vessels Tissue volume Small (20 cm 2 ) Large (200 cm 2 ) Temp increase 1 MHz: > 6.3 ° F C: > 7 ° F 3 MHz: > 14.9 ° F I: > 18 ° F Heat retention 3 min > 9 min C = Capacitive strategy I = Induction technique

Slide 11

Biophysical Effects Inflammation Assists in expulsion of cell trash and poisons Nonthermal: Alters dispersion rate over the phone layer Thermal Increases intramuscular digestion system

Slide 12

Biophysical Effects Blood and Fluid Dynamics Vasodilation expands: Blood stream Capillary filtration Capillary weight Oxygen perfusion Increased fibroblastic action and fine development Effects happen further than different types of warmth

Slide 13

Biophysical Effects Tissue Elasticity SWD can energetically warm profound tissues Alters collagen properties, permitting it to lengthen Requires extending amid and/or promptly taking after the treatment Multiple medications are required

Slide 14

Biophysical Effects Wound Healing Nonthermal SWD expands rate of phagocytosis Number of adult arrangement packs increment ATP movement increments (helping wound recovery) Necrosed muscle filaments diminish

Slide 15

Metal embeds or metal gems (know about body piercings) Cardiac pacemakers Ischemic regions Peripheral vascular illness Perspiration and wet dressings: The water gathers and thinks the warmth. Inclination to drain, including feminine cycle. Pregnancy Fever Sensory misfortune Cancer Areas of specific affectability: Epiphyseal plates in kids The private parts Sites of disease The belly with an embedded intrauterine gadget (IUD) The eyes and face Application through the skull Contraindications
