Phases

movement of current in one direction
Interpulse Interval
- Time btwn the pulse
- Muscle needs to repolarize
Amplitude
- How high it is
- Greater amplitude, higher the recruitment
Rate Of Rise
- most important characteristic in depolarizing nerve
- Needs to go up quickly
Phase charge

the number of electrons in the phase
Pulse charge
- the number of electrons in the pulse
- Sum of phase charges
Pulsed Waveforms (Types of Pulses)
- Monophasic
- Biphasic
- Symmetrical biphasic
Monophasic Pulse

movement of current in one direction
Biphasic Pulse

Movement of current in both directions
Symmetrical Biphasic Pulse

Movement of current in both direction is identical
Asymmetrical Biphasic current

Movement of current in each direction is different
Asymmetrical Biphasic Balanced
- the Phase charge (number of electrons in each phase) are equal
- Not symmetrical but same amplitude
Asymmetrical Biphasic Unbalanced

the Phase charge (number of electrons in each phase) are unequal
Polyphasic Pulse
- Pulses with 3 or more phases
- Polyphasic pulses can be balanced or unbalanced depending on the phase charges
- Usually fast frequency sinusoidal waves. These pulses are also referred to as bursts.
