The InterX® Professional Devices

The InterX Delivers An Interactive, Damped, Bi-Phasic, Sinusoidal Waveform Through Fixed Stainless Steel Electrodes.

What is InterX?

 

InterX is a medical device that uses electrical stimulation for relief of acute and chronic pain. The device is unusual in that it incorporates a feedback system that modulates the electrical stimulus in response to the impedance of the patient’s skin.

 

How does it work?

 

Interactive Neurostimulation therapy comprises a unique ability to locate the optimal treatment areas with the InterX, targeting them with specific interactive, high amplitude, high density pulsing current. Cutaneous stimulation does not cause muscular contraction and the InterX is safe to use over internal metal work.

The design of the flexible array electrodes ensures that most treatment is delivered to areas of low impedance. The low impedance on the skin is caused by an increase in the sympathetic skin response and research shows that these points correlate to myofascial trigger points1 and major nerve branches.

The device generates high amplitude, high density current and damped biphasic electrical impulses that are delivered to the tissue via a set of electrode pads placed directly to the skin surface at the required area, thus enabling stimulation of all cutaneous nerve endings which in return triggers the bodies response with a number of pain relieving mechanisms. The InterX is sensitive to changes in skin impedance, where electro-physiology of the skin and underlying tissues controls output from the device by varying the voltage in order to maintain a constant peak current.

It can be applied directly to the skin and moved around over the skin without electrode gels. This allows the user to be able to assess the impedance of the skin to identify and target optimal treatment points. This has led to the development of the three step protocol of almost every InterX treatment: Scan, Target, Dynamic.

 

Proven Success 

 

The InterX produces a pulsing current ranging from 15 – 480 pulses per second. The research shows that low frequency stimulation causes a release of endomorphin, beta-endorphin and enkephalins where a high frequency stimulation releases dynorphins3. The broad range of pulsation by the InterX ensures that all types of endorphines are released.

InterX is clinically proven to be consistently effective at getting patients back into active rehabilitation sooner, with less pain and more ROM6. Furthermore, it provides non-drug pain relief; increases range of motion and reduces swelling in acute injuries.The InterX has shown to be highly effective across a wide range of conditions, helping a broad spectrum of patients return to an active lifestyle.

FAQs

Why is InterX so effective?

Specificity of the Stimulation (Scan)
InterX identifies and treats very specific areas of low impedance. These are areas of skin where nerve endings are displaying a response to injury or pain.. So the stimulation is delivered exactly where the body needs it. This is not always where the pain is so it is a great benefit to be able to scan the area with the InterX to identify these points.The high density current (Target)
The high amplitude, short pulse width, dynamic waveform elicits a greater response from the body than other electrical stimulation. The InterX has closely spaced electrodes which means the current is very high density and very specific and not restricted by muscle contraction. It is believed that this stimulates a neuropeptide/cytokine cascade which is believed to create a longer lasting effect. Central nervous system responses are often observed too.The Interactive Waveform
The parameters of each individual pulse are controlled by the electrophysiology of the tissue. The waveform changes constantly as the body responds to the stimulation and pain relief. This stops the body accommodating to the stimulation making it more effective. It also means that there is no need to use messy conductive gels.

What is the mechanism of action?

There are two generally accepted theories for the mechanism of action of electrical stimulation devices; The “Gate Control Theory” and the “Stimulation of the release of endogenous opioids”. The exact mechanism of InterX is not yet fully understood and there appear to be a number of mechanisms at work based on the applications used and clinical outcomes that are observed. The amplitude of the stimulation is sufficient to cause endogenous opioid release and this may explain the immediacy of results experienced with InterX. Often pain relief lasts long after the treatment is over which hints at a neuropeptide/cytokine cascade effect and a CNS response. Clinical trials have shown reduction of inflammation and improved tissue formation with InterX stimulation which is also supported with anecdotal evidence.

How much does InterX cost and will my insurance cover it?

Treatment is eligible for reimbursement through individual clinics and practitioners, but the device is not covered under most insurances.

Is the device masking pain?

The InterX does not mask pain. If that were the case pain would return soon after the treatment ended. InterX is committed to clinical trials to research the sustained relief as well as reduction of inflammation that is observed following InterX therapy.

What should I expect from treatment?

InterX® therapy will be delivered by a trained practitioner, often in a clinical or sports setting. Typical treatments last from 15 – 30 minutes and the procedure will involve applying the hand-held device or its remote probes directly to the skin. Treatment will be on the skin of the involved area, and often non-involved areas on the opposite side of the body or the back.

The device may be held stationary or moved along the skin in sweeping motions, depending on the chosen mode of treatment. The sensation the patient may feel a tickling or vibrating sensation, or it may feel like a prickling or fine “needling” sensation. Some people are more sensitive than others to neurostimulation. The way your body responds to the treatment may not be the same as the next person. There is the potential that people who are very sensitive to neurostimulation may temporarily experience discomfort or light-headedness.

The number of treatments needed will depend upon the severity of your condition and how long you have had the problem. Quite often patients feel relief after 1 – 3 treatments but complex long standing conditions may require more effort.

The InterX® products can be applied independently as a full treatment or concurrently with existing therapy (physical or occupational) activities to meet and enhance therapy goals. The number of visits and duration of treatment is highly dependent upon the complexity of the patient’s medical history and condition, and whether the InterX® product is used independently or as a concurrent treatment. Case examples:
Acute minor ankle sprain may only require one 15-minute session for a healthy individual when InterX® therapy is applied as a concurrent treatment to active therapy.
Chronic low back pain and a complicated medical history may experience a 30-minute treatment and require 3-4 treatments per week for 2-3 weeks.
Post-operative ACL repair may experience a 15-minute InterX® treatment multiple times before each physical therapy session.
Once therapy has begun, it is important to complete the full, recommended treatment course in order to experience optimum relief from symptoms. Neurostimulation activates a physical response, which may increase the sensation of pain for a few hours. Adherence to the full course of treatment will minimize symptoms that a patient may experience during the natural healing process.

Is there a warranty on the device?

Yes, there is a one year warranty on all InterX devices and electrodes. Extended warranty options are available.

Who can benefit from InterX treatment?

InterX® therapy is a safe, non-invasive treatment that can be used on patients of all ages.

Do I have to hold the device through the whole treatment?

No, the Flexible Array electrode allows for unattended treatment. We recommend scanning the area first with the main device, then targeting the area with the flexible array during which time you can direct the patient to perform exercises or you can continue the treatment unattended.

What is InterX?

InterX is an advanced form of Neurostimulation that integrates into existing treatment programs to enable enhanced results with both acute and chronic conditions. InterX is FDA cleared for acute and chronic pain relief and pain management.

What is InterX used for?

The InterX products are effective for:

  • Acute and chronic pain relief and the resulting increase in range of motion
  • Neuropathic and nociceptive pain
  • Reducing rehabilitation times from sports injuries and other acute trauma
  • Muscle relaxation, reducing muscle cramps and spasms
  • Enhancing neuromuscular re-education

What does an InterX treatment involve?

Scan – The treatment area is scanned using the InterX device to identify specific areas of low impedance. These are optimal treatment points for InterX stimulation. The scanning can be done either by sliding the device over the skin or by placing the device and taking numerical measurements.

Target – These areas of low impedance are then targeted with very specific stimulation. The interactive stimulation adjusts constantly in response to changes in the electrophysiology of the tissue. This specific, dynamic stimulation is unique to this technology.

Dynamic – If appropriate, the patient is moved through a series of positions, stretches or exercises while stimulation is applied to points of pain. The portability and ease of application make this a very quick and effective application where neuromuscular and proprioceptive re-education can be combined with interactive neuro-stimulation for enhanced results.

How long is an InterX treatment?

The time needed for treatment can vary but averages approx. 15 minutes. Very short treatments can be used on the sidelines of a sports game taking only a few minutes. When treating more difficult chronic conditions, the session may last up to 30 minutes as there is a larger area of the body to scan when incorporating neurologically related areas.
