What is 1 + 3?
continuous and unidirectional flow of charged particles
Direct current - uses
iontophoresis, stimulating denervated muscles to contract, occasional wound healing
continuous and bidirectional flow of charged particles
Alternating current - uses
muscle contraction, pain management
interrupted flow of current, series of pulses separated by no current flow, may be uni or bi directional
tissue healing, acute edema, high voltage pulsed current
muscle contraction of small muscles, pain control with TENS
muscle contraction of large muscles, pain control with TENS
Interferential Current or IFC
interference of 2 AC's of slightly different frequencies at a 90 degree angle. 2 channels 4 electrodes
difference between the frequencies of the original AC's
IFC - benefits
pain management, more comfortable, higher current in deeper tissues, stimulates larger area.
total frequency dependent opposition to current flow
electrical force moving charged particles through a conductor between two regions or points
