AIIMS November 2011 – MCQ 188
Which is not a deep heat therapy
a) Short wave diathermy
b) Ultrasound therapy
c) Infrared therapy
d) Microwave therapy
Repeat question – AIPGMEE 07 MK q249
Correct answer : c) Infrared therapy
Infrared therapy is a type of superficial heat therapy.
One Comment
The following areas are treated selectively by the listed modalities:
•
The application of microwave radiation or of shortwave diathermy with capacitor plates, at a frequency of 2456 MHz, can provide selective heat to deep subcutaneous tissue and superficial muscle.
•
Shortwave diathermy with an induction coil applicator, administered at 27 MHz, can heat superficial muscle.
•
Microwave diathermy administered at 915 MHz can selectively, but thoroughly, heat muscle.
•
Ultrasonography administered at a frequency of 0.8-1 MHz preferentially heats joints, ligaments, tendons, tendon sheaths, fibrous scars, nerve trunks, and myofascial interfaces. Ultrasonography is especially useful for heating joints that have a thick layer of overlying soft tissues that shortwave diathermy or microwave diathermy cannot penetrate.
•
Shortwave diathermy with internal electrodes, administered at 27 MHz, can provide selective heat for pelvic organs in cases of chronic pelvic inflammatory disease and can be employed for the management of coccygeal muscle spasms (such as those of the urogenital diaphragm).
