modalities Flashcards
what type of estim for mm strengthening? wave form?
Pulse Frequency (pps)? Pulse Duration (µS)
Intensity/Duration?
NMES: Wave form = Alternating Current, Russian
PPS = 50-80 / 200-800
1:5 duty cycle
Duration = 10-20 strong contractions
Contraindications for Estim
pacemaker or implanted electronic devices
uncontrolled hyper- or hypotension
peripheral vascular disorders (for fear of releasing blood clots)
areas of neoplasm or infection
pregnancy
Must be able to provide clear feedback
Duty Cycle = ?
- percentage of on time to total time between pulses
? = number of electrical pulses delivered to the body in one second
Frequency - Also called pulses per second (pps), Hertz (Hz) with AC
Pulse frequency for high freq TENS for pain relief?
Wave form?
> 50; generally 80-110 pps
pulsed AC or DC
Low freq TENS to point of ??
PPS / Duration
visible muscle twitch
PPS <10 / duration > 150
Estim for Edema management (acute)
Edema Management (acute)
pulsed DC/monophasic pulsed to comfortable sensory threshold; just below motor response
20 mins minimum - hours OK
Tips for Estim success
informed consent, and checking for changes in the patient’s medical history since the last visit
Cleaning the patient’s skin with alcohol to remove oil and dirt before electrode application
Clipping excess body hair under electrodes
No HP during, CP ok
Use large nodes for large areas, smaller nodes for smaller areas
skin checks before and after application of any modality.
how many channels for tissue repair? (mono/bi/quad?)
One channel: active electrode in the treatment area and the dispersive is placed proximally to target area >12-18” away
For Ultrasound; best absorbing tissues are those with high collagen content = what tissues?
Vs what reflects?
– LIGAMENT, TENDON, FASCIA, JOINT CAPSULE, SCAR TISSUE = best
Bone/cartilage reflect!
Mode req for HEATING on US?
continuous US
During the inflammatory phase, US has a stimulating effect on what cells?
for tissues in which there is an inflammatory reaction, but in which there is no ‘repair’ to be achieved, the benefit of ultrasound is to promote the normal resolution of the inflammatory events
mast cells, platelets, white cells with phagocytic roles and macrophages
% bodyweight for mm spasm - traction? Lumbar
25% bodyweight
As per proper safety procedures and to reduce periosteum burning, it is recommended to move the ultrasound head at a rate of x cm/second
4
To prevent skin burning, ensure use of x-x towel layers between the patients skin and the hot pack/heat source
6-8, unless the hot pack is in a cover- the cover can be counted as 2-3 towels depending on its age and thickness
Appropriate temperatures of the water in the hydrocollator must be maintained at x° F as per the safety guidelines.
164
Dexamethasone is a ? charged solution
you would place the saline solution on the x electrode to ensure proper delivery of the medication. Dexamethasone would be placed in the x electrode.
dex = negative
saline = positive electrode
dex = negative electrode
Impaired sensation is considered a precaution, but not a contraindication. T/F?
T
Ice pack duration to achieve an effect in treating spasticity?
up to 30 minutes; checking the patient after 10-15 minutes to be sure there aren’t adverse effects.
____ traction for a ____ amount of time is indicated for acute phase of spinal injury
continuous traction for a short amount of time
estim settings for the inflammatory phase of healing or with infection present
waveform/polarity/ pps
Waveform: high volt pulsed current (HVPC);
Polarity: negative;
Pulse frequency: 60-125 pps
WHAT polarity is recommended when the goal is to enhance granulation tissue formation in the wound bed and when re-epithelialization is desired.
Negative
Application of ultrasound treatment for a chronic condition is best suited at the x setting.
continuous
The proper range for cervical traction is x-x degrees of cervical flexion
proper lbs/force for cervical traction?
20-30 deg
force of 20 pounds
