Quiz for 11/17 Flashcards
MENS stands for
Microcurrent Electrical Stimulation
Uses for MENS
- Non union bone Fx-post cast, not healed yet
2. Skin wounds-diabetic ulcers, bed sores
Does MENS use AC or DC
DC and carrier freq
is MENS felt by the patient?
No, athletes swear by it
Main function of MENS
to produce ATP to increase cell respiration and healing time
SWD is high or ultra high freq
high
frequency of SWD
27.12 MHz
SWD wavelength
11meters
SWD penetration depth
up to 2in (muscle layer)
SWD temp range
109.4-113 degrees F
SWD utilizes what tissue propagation
conversion(cells hit each other producing heat)
SWD tx time
20-30min
Kirchoffs law
highest density->most resistance->most heat
Eddy Currents
turbulent electric flow, some current hits muscle and others hit bone-Turbulence causes friction=heat
EM-SWD is good for
induction Vascular magnetic field out of circuit spacing not needed
ES-SWD is good for
Condensing deep cavity(organ tissue) adipose effect electric field in circuit need 1 layer of spacing(towel)
Induction coil SWD
wraps completely around extremity-need one inch of spacing
Pancake coil SWD
Used on flat surfaces such as back-use 1in of spacing
Diplode Drum SWD
Di=2
Covers anterior, medial, and lateral surface of extermity
use 1 layer
Monoplode drum SWD
one surface only, use 1 layer
Condensor pads SWD
Electro-static
One pad low, one high
use 1 layer
Space plates SWD
one anterior shoulder, one posterior shoulder
air space/space plates SWD
2=electrostatic
use one layer
Sinus Mask-SWD
use one layer
used for sinusitis
Layer rule for SWD
if electrode has air space, use i layer
if no air space, use 1in
towel rule for SWD
must always use towel to prevent burn!
Edge effect
keep electrodes/cables atleast 1in away from each other or burn
4 foot rule SWD
must not have anything battery operated within 4 ft of machine when on
SWD contraindication
Contact lenses, pacemakers, IUD
US uses what effect
reverse piezoelectric effect: Electrical energy into mechanical energy(sound waves)
US freq
1.1MHz, 2MHz, 3.3MHz
Everything can be treated with 1MHz
US wavelength
0.15cm
US voltage
100-2000v
US penetration
1 MHz=up to 2in-bone ligament tendon
3.3 MHz= up to 1in- muscle/fascia
US utilizes
conversion
Modality output vs therapeutic output
Watts vs Watts/cm squared
US tx time
acute-5min
chronic-10-15
US uses what cable
coaxial along with microwave modality
