Passive Care - Interference Current

Question 1

Interference Current: Action

Answer 1

Electrokinetic
Analgesic
Decrease Edema

Question 2

Interference Current: Results

Answer 2

Deep muscle contraction
Fatigue
Edema reduction
Pain Control

Question 3

Interference Current: Waveform

Answer 3

1. Two circuit static (one specific treatment area)
2. Two circuit scanning (sweeping) pre-mod freq treats wide area
3. Three circuit (3 dimensional treatment area)

NOTE: Two sine waves of medium frequency decrease skin resistance and create an endogenous polyphasic beat wave

Question 4

Interference Current: Indications

Answer 4

Facial Neuritis (Bell's Palsy)
Musculoskeletal (sciatica, ankle sprain, heel spur, fractures)
Urogenital Dysfunction (stress and urge incontinence)
Pain Control (trauma, sprain/strain)
Vascular Condition (Raynauds - pad on stellate ganglia to clock sympathetic chain)

Question 5

Interference Current: Contraindications

Answer 5

To all electrical modalities

Question 6

Interference Current: Frequency

Answer 6

Medium Frequency: 1-10,000 (2,000 = RS) (4,000 IF)

Low Frequency = treatment

Question 7

Interference Current: Miscellaneous

Answer 7

1. Sweeping / Sensory: pre-modulation current “sweeps” area, avoids accommodation (pps)
2. Vectoring / Motor: increases the treatment area
3. Scan: mA = area & size of muscle fibers effected
4. Dosage: muscle strengthening 10 s on 50 s off
   muscle spasm 10 s on 10s off
