This is when one object produces electromagnetic property in another
Electro-induction
Measurement of charge?
Coulomb
This is assoc. w/ pulse width, interpulse width, & freq.
Waveform
Magnitude/depth of an electric charge
Amplitude
Electricity that flows (number of electrons)
Current
This increases or decreases volts
Transformer
Ability to store up electrical energy
Capacitance (Ohm)
Property of substance to oppose current. Measured in Ohms.
Resistance
Difference in force b/w two objects. Measured in Volts.
EMF (Electromagnetic force)
- greater the charge = increase EMF
- greater the distance = decrease EMF
Slows down (dampens) electric charge.
Impedance
The time necessary for contraction when the rheobase is doubled
Chronaxie
The minimum volts necessary to excite a nerve
Rheobase (threshold)
Type of EMS you should assoc. w/ “paralyzed muscle”, “weak muscle”, or “research”
Faradic
Galvanic & Faradic current are compared to determine extent of damage & prognosis of nerve damage to muscle.
Reaction of Degeneration (R.D. Factor)
Best method of muscle testing
EMG (Electromyography)
