Electric Modalities Flashcards
It is the application of electrical stimulation to facilitate a desired therapeutic response

Nerve and muscle
stimulation
- Driving force that moves electrons or pushes charge
Voltage
Materials in which ions or electrons move freely
Conductors
materials in which charged particles are not free to move or do not move
easily
Insulators
Unresisted movement of ions or electrons in a conductor in response to a voltage force
Current
Frequency-dependent form of resistance
Impedance
