Anterior cervical area
Through the chest
Through the head
Pacemakers and ICDs (implantable cardioverter defibrilators)
Abdomen, pelvis, lumbar areas of pregnant women in FIRST tri
Metal implants
Epilepsy
Areas of hemorrhage
Cancer

Damaged skin
Unknown etiology
3
Q

Is it ok to do IFC over a pregnant women’s ankle?

A

YES- just not over her uterus

4
Q

Clinical goals of IFC?

A

Decrease pain

*strengthen pelvic floor

5
Q

Size of treatment area for IFC?

A

Smaller area= use Premod: 2 pads, 1 each side of pain

Larger area= use IFC: 4 pads in crisscross cloverleaf pattern

6
Q

What is the temporal presentation for IFC?

A

Acute (60-150hz, or variations like 60-120, 80-150)

Chronic (0-15hz, or variations like 0-10, 1-15)

7
Q

Nerve fibers targeted during IFC?

A

A beta fibers (acute, 60-150, no muscle contraction)

A delta fibers (chronic, 1-15, some muscle twitch)

8
Q

How many channels, leads, and electrodes are used for IFC?

A

1 channel/lead/2 electrodes (premod)

2 channels/leads/4 electrodes (true interferential)

9
Q

Treatment time for IFC?

A

15-20 minutes

10
Q

Intensity for IFC?

A

Patient comfort

11
Q

What is the difference between using premod and true interferential?

A

Size of treatment area

12
Q

Indications for neuromuscular electrical stimulation (NMES)?

A

Muscle re-education
Retard atrophy
Muscle strengthening
Decrease muscle spasm through fatigue

13
Q

Contraindications for NMES?

A
Anterior cervical area
Through chest
Through head
Pacemakers and ICDs
Abdomen, pelvis, lumbar areas of pregnant women in their FIRST tri
Metal implants
Epilepsy
Areas of hemorrhage
Cancer
Confused and unreliable patients
Damaged skin
Unknown etiology
14
Q

Is it ok to perform Russian stim over a pregnant woman’s ankle?

A

YES- just not over her uterus

15
Q

Clinical goals of NMES?

A

Fatigue of a muscle spasm

Re-educate a muscle after lack of use

16
Q

Size of treatment area of NMES?

A

Fatigue of single muscle: 10/10 single muscle 10 min
Reeducate a single muscle: 10/50 single muscle 10-15 min
Fatigue bilateral muscle groups: 10/10 cocontract 10 min
Reeducate agonist/antagonist muscle pairs: 10/50 reciprocal for 10-15 min

17
Q

Intensity/amplitude of NMES?

A

Patient tolerance (turn up slowly!)

18
Q

How many channels for NMES?

A

Single muscle= 1 channel

Bilateral muscle groups/agonist antagonist muscles= 2 channels

19
Q

What is the clinical goal of Russian current 10/10 normal?

A

Fatigue muscle spasm

20
Q

Clinical goal of Russian current 10/50 normal?

A

Muscle reeducation, recovery from/prevent atrophy

21
Q

Clinical goal of Russian current 10/10 co contract?

A

Fatigue muscle spasm

22
Q

Clinical goal of Russian current 10/50 reciprocate?

A

Muscle reeducation, recovery from/prevent atrophy

23
Q

NMES ramp time for patients?

A

New patient= 1.5-2 seconds/10 min

Old patient= 0.5-1 second

24
Q

Indications for ESTHR (electrical stimulation for tissue healing and repair) and HiVolt pulsed current and microcurrent?

A

Stimulate healing

25
Q

Indications for HiVolt ONLY?

A

Reduce edema

Decrease spasm/guarding (pelvic floor muscles)

26
Q

Contraindications for ESTHR and HiVolt?

A
Osteomyelitis (traps infection in bone)
Cancer
Electronic implants (pacemakers, ICDS)
Anterior cervical area
Through chest
Through head
Over metal implants
Abdomen, pelvis, lumbar areas of pregnant woman in FIRST tri
Areas of hemorrhage
Unknown etiology
27
Q

Is it ok to perform HiVolt on a pregnant woman’s ankle?

A

YES- just not over uterus

28
Q

What is another name for DC current? What is the purpose of it? Which modality does this pertain to?

A

Galvanic current, so each electrode has a different polarity

Pertains to HiVolt

29
Q

Are different sized electrodes used with HiVolt? What are they called?

A
Yes, two different sizes are used
Active electrode (larger) is placed in area of injury
Dispersal electrode (smaller) placed proximal to active electrode
30
Q

What are the clinical goals of HiVolt and what do the different polarities mean?

A
Inflammatory phase (+): attracts neutrophils and macrophages
Repair/remodeling phases (-): attracts fibroblasts, epidermal cells, keratinocytes
Reduce edema (-): repels short peptides and small proteins
Fight infection (+/-): change polarity every 3 days
31
