E-Stim Ultrasound Practical Flashcards
When using high volt for edema, what is the first thing you should do to set up the machine?
Move the black cables to the middle “Hi-Volt” port, and use the side that has a tag that says “Active” as the distal electrode
What is the correct electrode selection for using hi-volt for edema?
What is the patient position?
Small electrode at the site of the swelling (distal), large disperser electrode proximal
The limb should be elevated (Supine w/ leg elevated if reducing ankle swelling)
Case: Pt is 1wk s/p ACL reconstruction, assist w/ quad activation
Russian
Muscular Re-education
Case: Pt is 1 week s/p RTC repair and needs a way of managing pain
Conventional TENs (Because it’s for acute injuries)
Case: Pt has chronic Bilateral lumbar pain. Provide pain relief.
IFC (Because it has 4 electrodes and therefore can cover the entire lowerback)
Case: P has very tight achilles tendon and calf. Provide modality to assist w/ stretching.
Russian Increasing ROM
note: apply to OPPOSITE muscles to help stretch this muscle (Tib anterior)
or
Ultrasound vigorous thermal
Case: Pt has severe lateral arm pain 3 weeks after tearing middle delt. Provide modality for pain relief.
Conventional TENs or IFC
Pt has severe ankle swelling 4 days s/p sprain. Manage Edema.

What is it for?
Frequency: 100
Duration: 100
Intensity: Tolerable Sensory
Acute Pain/Post Surgery
What are the settings of acupuncture like TENs?
Frequency:
Duration:
Intensity:
What is it for?
Frequency: LOW, under 20
Duration: HIGH 100-600
Intensity: High enough to activate motor
(Place over motor point)
For Chronic pain
What kind of TENs do you use for a trigger point?
What are the settings?
Noxious Level
Frequency: LOW, 1-5
Duration: HIGH, 100-1000
Intensity: Muscle Contraction acceptable, high intensity sensory
What kind of TENs will you use for fast pain relief during debridement?
What are the settings?
Brief Intense
Frequency: HIGH, 100
Duration: HIGH 100-600
Intensity: Muscle Fasciculations to sustained contraction
How long is the treatment for Conventional TENs?
30+ minutes up to a few hours
How long is the treatment for acupuncture-like and Brief Intense TENs
15 mins
How long is the treatment for noxious level TENs?
“Until the pain is no longer perceived”
So I’ll say 30 mins i guess…

Duty cycle: 1:5 -> 1:3 -> 1:1 depending on fatigue
Treatment time: 15 mins
MOTOR POINT
When using e-stim for increasing ROM what kind will we use?
What are the settings?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
Where will we put it?
Russian
Frequency: 35-55(Beginning of tetany range)
Duration: 200-600
Intensity: Comfortable muscle contraction:
Duty cycle: 1:5 -> 1:3 -> 1:1 depending on fatigue
Treatment time: 90 minutes or 3 sets of 30
Put it on antagonistic muscle
When using E-Stim for muscle strengthening, what will we use?
What are the settings?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
Russian Current
Frequency: 50-85(Tetany range)
Duration: 200-600
Intensity: 60% of voluntary maximum isometric contraction
Duty Cycle: 1:5
Time: 3x10 reps
Note: add gradual ramp to peak intensity
When using E-Stim for prevention of muscle atrophy, what settings will we use?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
Russian current
Frequency: 50-85 (tetany range)
Duration: 200-600
Intensity: 25% of Maximum voluntary muscle contraction
Duty Cycle: 1:5
Time: 3x10 reps
Note: almost the same as strenghtening
When using E-Stim to control edema, what will we use?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
High Volt
Frequency: 35-55 (beginning of tetany range)
Duration: 200-600
Intensity: Comfortable Muscle Contraction
Duty Cycle: 1:1
Time: 20-30 mins
Elevate the body part, dont forget to use a large disperser electrode mixed with a smaller active electrode. Dont forget to change the wires to the high volt port (in the middle of the machine)
What e-stim would you use to control edema if they cant tolerate normal high volt
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
Edema control: sensory level
Still high volt
Frequency: 120 (high)
Duration: 2-10 LOW
Intensity: 10% less than what produces a muscle contraction
Duty Cycle: continuous
Time: 30 mins
What kind of e-stim is best for pain control?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:
Frequency: 4100-4000 = 100
Duration: 120
Intensity: Sensory level
Duty cycle: continious
Time: 10-20 minutes
Note: if you select IFC on the machine it will give you all the correct default settings, you just have to turn up the intensity.
Add in sweep if you want them to not accomadate to the frequency.
Use target mode if you want to target one area
Don’t forget the electrodes must be in a cross pattern with the channels diagonal
