What parameters are used for muscle strengthening using a TENS unit?
Pulse Freq.
35-80pps
Pulse Dur.
150-200ms (small), 200-350ms (large)
make sure to place over motor points.

Mechanism of Action
Overload Principle- at least 50% max. contraction
Treatment time 10-20 min every 2-3 hours when awake
What are the parameters for muscle reeducation?
35-50pps

150-200ms(small) 200-350ms (large)
What are the parameters for Muscle spasm reduction?
35-50pps

150-200ms(small) 200-350ms (large)

Treatment Time: 10-30 min every 2-3 hours until spasm relieved.
For Pain modulation what are the parameters for Conventional (high rate)?
100-150pps

50-80ms (depolarize only A-beta)

Amplitude= to produce tingling

Duration: may be worn 24 hours, as needed for pain control.
How does Conventional(high rate) control the pain? By releasing endorphins or gating at the spinal cord?
gating at the spinal cord
For Pain modulation what are the parameters for Low Rate (acupuncture-like)?
2-10pps

200-300ms (depolarize motor nerves and A-beta)

Amplitude: to visible contraction

treatment time: 20-30 min
How does Low Rate control the pain? By releasing endorphins or gating at the spinal cord?
Endorphin release
What are the parameters for burst mode TENS?
preset at 10 bursts

100-300ms

Amplitude: to visible contraction

Treatment time:20-30 min.
What are the parameters for tissue healing at the Inflammatory phase/infected?
HVPC (monophasic)
(negative polarity 45-60 min. duration)
60-125pps
40-100ms
Amplitude: Produce comfortable tingling.
What are the parameters for tissue healing at the Proliferation phase/clean?
HVPC (positive polarity 45-60 min. duration)
60-125pps
40-100ms
Amplitude: Produce comfortable tingling.
What are the parameters for controlling edema when it is associated with inflammation?
HVPC (negative polarity)
100-120pps
40-100ms
Amplitude:Produce comfortable tingling
What are the parameters for controlling edema when it is associated with lack of motion?
Biphasic
35-50pps (2-5sec equal on/off times)
150-350ms
Amplitude: Produce visible contraction
What are the contraindications for E-Stim?
1. Demand cardiac pacemaker or unstable arrhythmias
2. Placement of electrodes over carotid sinus
3. Areas where venous or arterial thrombosis or thrombophlebitis is present
4. Pregnancy-over or around abdomen or back
What are the precautions of E-Stim?
1. Cardiac disease
2. Patients with impaired mentation or in areas with impaired sensation
3. Malignant tumors
4. Areas of skin irritation or open wounds
5. Iontophoresis after other physical agents
What do you use for a denervated muscle?
You use a continuous DC current for at least 10 ms.
Short pulses and low-current amplitudes are used for sensory or motor stimulation?
Sensory stimulation
Long pulses and higher amplitudes are used for sensory or motor stimulation?
motor stimulation
