1
Q

Interference Current: Action

A

Electrokinetic
Analgesic
Decrease Edema

2
Q

Interference Current: Results

A

Deep muscle contraction
Fatigue
Edema reduction
Pain Control

3
Q

Interference Current: Waveform

A
  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

4
Q

Interference Current: Indications

A
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)
5
Q

Interference Current: Contraindications

A

To all electrical modalities

6
Q

Interference Current: Frequency

A

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

Low Frequency = treatment

7
Q

Interference Current: Miscellaneous

A
  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
