Correct Answers | Latest Update
What is short wave diathermy?


✓ -:- a modality that emits electromagnetic energy that is capable of

producing temperature increases in the deeper tissues or have other

physiological changes within tissue for healing




__ MHz is the msot commonly used short wave diathermy because it has the widest

bandwidth and easiest to generate


✓ -:- 27.12 Hz




T/F Short wave diathermy can interfere with communication signals


✓ -:- true




What is an advantage of short wave diathermy compared to hot packs and ultrasound?


✓ -:- better than hot packs - can penetrate deeper tissues

better than ultrasound - does not concentrate at periosteum and cause burning; it can also

cover larger areas

Short wave diathermy should not be used in those with ___ as the nerve can cause

conduction block dt shortened duration of sodium channel opening the node of Ranvier

during neuron depolarization


✓ -:- multiple sclerosis




Thermal effects of diathermy


✓ -:- Used to heat large, deep areas of tissue

Superficial tissues—vasodilation --> increase circulation with increased temperature;

increase pain threshold = reduce pain; increase rate of nerve conduction


Deeper tissues—increase tissue extensibility




Short wave diathermy when pulsed at low average intensity allows tissue temperature to be

maintained dt heat quickly dissipating through the blood. What nonthermal effects does it

have?


✓ -:- 1. immproves tissue healing by altering cell membrane function and

cellular activity (accelerate calcium ion binding, NO release)




2.increases microvascular perfusion and accelerate tissue healing and increase oxygenation

What are indications for using short wave diathermy?


✓ -:- 1.fractures

2.any pain or edema (rotator cuff syndrome, ankle sprain, low back pain)


3.soft tissue healing (incisional wounds, pressure ulcers, tendon injuries)


4.OA




What are contraindications to short wave diathermy? (7)


✓ -:- 1. during pregnancy esp in the pelvic and abdominal area

2.over the eyes


3.over the testes


4.over growing epiphyses


5.metal implants/jewellry


6.pacemakers and implanted or transcutaneous neural stimulators


7.malignancy




Sine wave uses a __ frequency current, __ voltage, and __ amperage


✓ -:- low everything!
