Q

What is the correct electrode selection for using hi-volt for edema?

What is the patient position?

A

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)

17
Q

How long is the treatment for noxious level TENs?

A

“Until the pain is no longer perceived”

So I’ll say 30 mins i guess…

Frequency:
Duration:
Intensity:
Duty cycle:
Treatment time:

Where do you set it up?

A

Russian

Frequency: 35-55(Beginning of tetany range)
Duration: 200-600

Treatment time: 15 mins

MOTOR POINT

19
Q

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?

A

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

20
Q

When using E-Stim for muscle strengthening, what will we use?

What are the settings?
Frequency:
Duration:
Intensity:
Duty Cycle:
Time:

A

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

21
Q

When using E-Stim for prevention of muscle atrophy, what settings will we use?

Frequency:
Duration:
Intensity:
Duty Cycle:
Time:

A

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

22
Q

When using E-Stim to control edema, what will we use?

Frequency:
Duration:
Intensity:
Duty Cycle:
Time:

A

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)

23
Q

What e-stim would you use to control edema if they cant tolerate normal high volt

Frequency:
Duration:
Intensity:
Duty Cycle:
Time:

A

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

24
Q

What kind of e-stim is best for pain control?

Frequency:
Duration:
Intensity:
Duty Cycle:
Time:

A

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

Time:

A

NMES

Frequency: Under 10

Intensity: Moderately strong muscle contraction
Duty Cycle: 1:5
Time: 3x10 3 times a day

Intensity: 1
Time: 5 minutes

29
Q

Intensity:
Time:

A

Moderate thermal

Intensity: 0.5
Time: 6.67 minutes

note:its double the superficial mild-thermal time

30

Intensity:
Time:

A

Intensity: 2
Time: 10 minutes

Note: it’s just twice the intensity of the moderate thermal
