Estim I Flashcards
(40 cards)
Motor points?
Locations on the skin where E-stim causes specific mms to contract. Created by Duschenne.
Gate control theory?
Define later
What can Estim do in the clinic?(3)
Produce mm contractions
Pain control
Promote tissue healing
Estim for mm contraction is used for?(7)
Strengthening MM reeducation Prevent atrophy Prevent DVT Prevent Pressure ulcers Reduce mm spasms Enhance transdermal drug delivery
3 types of electrical current wave forms?
DC (direct current)
AC (alternating current)
PC (Pulsed current)
What is DC?
A continuous electrical flow of charged particles.
Most commonly used in ionophoresis to stimulate contractions in mm)
What is AC?
An interrupted flow of charged particles
What can AC be used for?(3)
MM strengthening (contraction)
Pain control
Tissue healing
(most often used for Estim)
Interferential current?
Produced by the interruption of two med-Fq currents of slihtly different Fqs (4 electrodes used)
Premod current?
Alternating current with a med Fq 1000-10000Hz(2 electrodes)
Russian protocol?
Estim c specific parameters for quads mm strengthening.
Fq Med AC 2500Hz 10ms durration
Pulsed current types?(2)
Monophasic
Biphasic
Pulsed?
An interrupted flow of charged particles that flows in a series of pulses seperated by periods of no current.
Monophasic pulsed current?
Current only flows in one direction during a pulse
Biphasic pulsed current?
Current flows back and fourth during a pulse
Monophasic is used for?
Any Estim but most commonly for:
Tissue healing
Acute edema mgmnt
Most commonly used mono current?
High-volt pulsed current (HVPC)
In MonoP the currents are equal T/F and opposite_____?
True, polarity
In biP the currents are equal T/F and there is a ___ charge.
False
Pulse duration?
How long each pulse lasts
Shorter pulse durations are mostly used for?
Pain control
Longer pulse durations are mostly used for?
MM contraction
Phase duration?
The duration of one phase of the pulse.
Amplitude?
The magnitude of the current voltage. Also called intensity.
