|---|---|---|---|---|---|
| Direct current, | also referred to as Galvanic current, is characterized by a constant flow of electrons from the anode to the cathode (for a period of greater than one second) without interruption.
🗑
|
||||
| DC- Polarity remains | constant and is determined by the therapist based on treatment goals. Iontophoresis uses direct current.
🗑
|
||||
| Alternating current is characterized by polarity that | continuously changes from positive to negative with the change in direction of current flow.
🗑
|
||||
| Alternating current is | biphasic, symmetrical or asymmetrical, and is characterized by a waveform that is sinusoidal in shape.
🗑
|
||||
| Alternating current is used in | muscle retraining, spasticity, and stimulation of denervated muscle.
🗑
|
||||
| Interferential current | combines two high frequency alternating waveforms that are biphasic.
🗑
|
||||
| Interferential current attempts to reach . | deeper tissues using the higher frequencies of each waveform along with the overall shorter pulse widths
🗑
|
||||
| Interferential uses a frequency of | 50-120 pulses per second and a pulse width of 50-150 microseconds for pain management.
🗑
|
||||
| IFC frequency of 20-50 pulses per second and a pulse width of | 100-200 microseconds should be used for muscle contraction.
🗑
|
||||
| Interferential current is used in | pain management, muscle contraction, urinary incontinence, edema management, and migranes.
