High voltage electrical stimulation is a type of electrical stimulation that
your physical therapist may use to help decrease your pain or improve circulation
. It is also occasionally used to help with wound healing.
What is High Voltage electrotherapy?
High voltage electrical stimulation is a
type of electrical stimulation
that your physical therapist may use to help decrease your pain or improve circulation.
How much voltage is in a TENS unit?
The TENS unit is powered by a
9 volt
battery which produces pain relieving electrical pulses.
What is high volt estim used for?
High Voltage Stimulation is used by
physical therapists to decrease pain and enhance circulation in the injured tissues
. High voltage is known to speed the healing process by changing the type of cells around the wound.
What type of current is HVPC?
Recent Advances: HVPC is
a monophasic pulsed electric current
that consists of double-peaked impulses (5-200 μs), at very high peak-current amplitude (2-2.5 A), and high voltage (up to 500 V), at a frequency of 1-125 pulses per second.
Is a TENS unit AC or DC?
A standard TENS unit typically delivers a low-frequency (<50 Hz)
alternating current
to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being worn.
What is the most powerful TENS unit you can buy?
| Channels Dual | Modes 5 | Pads 4 | Output Maximum 150mA | Power Supply 2-AA Industrial Strength Batteries |
|---|
What are the side effects of electrical stimulation?
Side effects include
redness and irritation to the skin
which typically clears with topical moisturizer in 24 to 48 hours. The electrical current may start off as a slight tingling sensation and build to a pulling sensation.
Can electrical stimulation cause nerve damage?
Generally,
greater intensity, higher frequency, and longer pulse width stimulation
lead to more severe damage in nerve cells (McCreery et al., 2004). In addition, although short-term electrical stimulation is not damaging to nervous tissue, chronic electrical stimulation can damage nerve structure.
What are the benefits of electrical stimulation?
- May improve joint pain and swelling.
- Prevents and reveres muscle atrophy (loss of muscle mass/tissue)
- Enhances rehabilitation of muscles.
- Increases range of motion for tense muscles or tendons.
- Reduces stress and discomfort.
- Improves blood flow and circulation.
Is HVPC direct current?
High-voltage pulsed direct current (HVPC) has been shown to retard edema formation after impact injury in frogs, but the effectiveness of HVPC in reducing edema after other forms of trauma has not yet been established.
What are Diadynamic currents?
Diadynamic currents are also called
Bernard’s currents based on a sine wave with a frequency of 50Hz
. Due to the ease of generation of this current shape, they have been known almost from the beginning of electrotherapy, and their influence on the human body has been thoroughly studied.
What is high voltage galvanic current?
High volt galvanic (HVG) current has been used in many physical therapy clinics for
edema reduc- tion, pain reduction, ulcer healing
, increasing joint mobility, and prevention of disuse atrophy; how- ever, there have been few published studies re- garding the effectiveness of HVG in treating those conditions.
Do TENS machines loosen muscles?
The
electrical impulses can reduce the pain signals
going to the spinal cord and brain, which may help relieve pain and relax muscles. They may also stimulate the production of endorphins, which are the body’s natural painkillers.
What is DC and AC voltage?
Direct current (DC)
is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.
When is electrotherapy used?
Electrotherapy has been used to address
chronic pain and chronic fatigue
in general, as well as: Diabetic nerve pain. Fibromyalgia. Migraine headaches.
