How it works
The effectiveness of heat and cold in therapeutic circumstances can be attributed to two basic physical rules. Heat expands, cold contracts. This translating into the use of heat as a vasodilator – bringing nutrient rich blood to surface areas – and the use of cold acting as a vasoconstrictor – driving blood to the body’s core – nourishing and protecting the inner organs of the body. Used alone, heat can help to relax aching muscles, while cold reduces inflammation and inhibits pain. Pain reduction happens, in part, because the body’s pain receptors are particularly sensitive to changes in temperature. Cooler temperatures slow the velocity of nerve transmission, while heat tends to increase the velocity. The human body has certain tolerance levels when it comes to temperature. A hot bath is considered anywhere from 100 – 115 degrees (Above 115 degrees can be damaging) A cold bath would be in the range of 38 – 65 degrees. VORTEQ allows the user to adjust the temp to what is best for the patient. VORTEQ lets you set the exact temperature, exact amount of time and exact duration of treatment. VORTEQ targets specific location.... Contrast therapy can be useful in the easing of pain, reducing inflammation and increasing circulation. With understanding of the basic dilation and contraction action provided by the contrast in temperatures and practice, the use of localized contrast therapy can be effective in assisting the body’s own pumping action, both in the superficial portion of the circulatory system and the lymph system. The VORTEQ heats up then brings temp back to neutral then goes to cool then brings temp back to neutral then back to hot.. continue this rotation cycles for the duration of treatment time.
Thermal contrast therapy has a lengthy history in physical therapy practice for promoting healing from injury, but its use has been constrained by the need for tight temperature maintenance and timing, both requiring close oversight of the administering therapists. The patented VORTEQ® technology resolves the need for constant oversight because it automates temperature and timing control and makes the therapeutic application simple, easy and safe. VORTEQ® brings this historically proven clinically effective therapy into the 21st century. The Proven Effects of Contrast Therapy The scientific literature on the use of contrast therapy is fairly limited but with a number of high quality peer-reviewed studies demonstrating the effects on peripheral blood flow. Jerrold Petrofsky and others have done quality work assessing the effect of contrast therapy on lower extremity vasculature. One study demonstrated that the use of contrast therapy produces a statistically greater blood flow on skin blood flow in the feet than simple sustained heating.1 The results were quite surprising as seen in Fig. 1.
Starting from the same baseline, blood flow showed a steady and dramatic increase during each heating cycle dropping slightly below sustained heating at only 2 points, and increasing more than 40% during subsequent cycles, for an overall average increase of nearly 11% over the 20-minute treatment interval when comparing the contrast therapy with sustained heating. While the results were less dramatic in the diabetic population during this study, the blood flow increase during the heating cycles of the contrast therapy group still far surpassed the sustained heat results. Perhaps even more importantly for diabetic individuals, the rise in blood flow was particularly greater in blood flow to the bottom of the foot. (Fig. 2.) An older study assessed the impact of contrast bath therapy on lower extremity blood flow in individuals with rheumatoid arthritis, a group with much reduced peripheral blood flow. Over a 30 minute period of contrast bathing, lower extremity blood flow increased by an average of 95% five minutes after the therapy and remained increased by nearly 40% three-quarters of an hour after termination of the therapy.
2 Oxygen is an essential requirement in living tissues, and reduced oxygen availability presents significant risk to tissue viability. As the studies above demonstrate, an increase in skin blood flow is produced by heating and even more so by contrast therapy heating. But the increase in tissue heating also produces in increase in tissue metabolism, thus necessitating an increase in oxygen availability. Inflamed tissues also require this increase in metabolic activity, but fortunately an increase in blood flow can readily supply sufficient oxygen to support metabolic demand. An older study assessed the relationship of blood flow to tissue oxygen availability. Simple tissue heating, (raising skin temperatures from 34°C to 38°C) doubled subcutaneous tissue oxygen tension(from 47.7 Psqo2 to 97.4 Psqo2 )3 . So, thermal contrast therapy increases blood flow, which in turn supplies the required increase in tissue oxygen to better support the demands Fig. 1 Fig. 2 of tissue cell metabolism. This beneficial process allows tissues recover and heal from injury, and also allows the inflow of white blood cells to combat infection, all through a simple non-pharmacologic intervention. Because individuals with Type 2 DM often have diminished peripheral blood flow, they are more prone to skin breakdown and prolonged wound healing. In a study assessing the role of heating in the management of chronic lower extremity ulceration, the combination of heat plus a weak electrical current (20 mA) produced a doubling of blood flow both circumferentially around the chronic ulcers, as well as in the wound center.4 (Fig 3.) The result was a 75% healing of the chronic ulcers in 1 month, with the control group showing no healing and actual clinical worsening. Again, the increase in tissue oxygen availability obviously is an important component in this healing process. Fig. 3 Summary Thermal Contrast Therapy (TCT) can be efficiently, measureably and safely delivered by the VORTEQ® device. This therapy has been scientifically shown to increase blood flow, increasing oxygen availability to skin and other tissues, potentially healing injured tissues and chronic ulcers. These are common problems and TCT is an effective, non-pharmacologic option to promote tissue maintenance, healing and recovery.
Anyone suffering from pain or circulatory issues now have access to a method of natural pain reduction. With the use of VORTEQ®, rapid thermal contrast therapy (RTCT) greatly enhances regional blood flow. With increased blood flow comes inflammation reduction and a substantial increased delivery of healing agents to the targeted area, all of which are critical to the recovery process.
Contrast therapy has been effectively used on the following ailments:
- Diabetic Neuropathy
- Peripheral Arterial Disease (PAD)
- Opioid Addiction Crisis
- Complex Limb Ischemia (CLI)
- Below the knee amputations
- Above the knee amputations
- Muscle Spasms
- Post-Surgical Recovery
- Rheumatoid Arthritis
- Wound Healing
- Diabetic Ulcer
- Shin Splints
