ESTIM Flashcards
1
Q
Short Pulses and low-current amplitudes are used for?
A
- Sensory stimulation
2
Q
Longer pulses and higher amplitudes are used for?
A
- Motor Stimulation
3
Q
WaveForms
A
- Alternating Current (AC)
- Interferential Current (IFC)
- Premodulated Current
- Direct Current (DC)
- Pulsed Current
- Russian Current
- Iontophoresis
4
Q
Time Dependent Parameters
A
- Pulse Duration
- Phase Duration
- Interpulse Interval
5
Q
Effects of Electrical Currents
A
- Stimulation of AP in nerves (NMES)
- Action potential Propagation
- Direct muscle depolarization
- Ionic Effects
6
Q
Action Potential Propagation
A
- Once an AP is generated it triggers an AP in the adjacent area of the nerve membrane
7
Q
Direct Muscle Depolarization
A
- Denervated muscles do not contract in response to the pulses of electricity that produce contractions in innervated muscles
- This requires pulses of electricity lasting 10 ms or longer and is known as Electrical Muscle Stimulation (EMS)
8
Q
Contraindications for ESTIM
A
- Demand cardiac pacemaker or unstable arrhythmias
- Placement of electrodes over carotid sinus
- Areas where venous or arterial thrombosis or thrombophlebitis is present
- Pregnancy: over or around abdomen or LB
9
Q
Precautions or ESTIM
A
- Cardiac Disease
- Pt’s with impaired mentation or in areas with impaired sensation
- Malignant tumors
- Areas of skin irritation or open wounds
10
Q
Adverse Effects
A
- Burns
- Skin Irritations
- Pain
11
Q
Application Technique
A
- Eval Pt
- Determine appropriateness and safety
- Select device
- Prepare Pt
- Explain Procedure
- Remove metal / clothing in treatment area
- Inspect Skin
- Position Pt and device
- Check and apply electrodes
- Select treatment parameters: (Waveform, Polarity, Frequency, Pulse Duration, On/Off Time, Ramp Up/Down and Treatment Duration)
