Pressurized clothing is used to execute pressure treatment on the body. Pressure treatment has been used in different indications since the 1950s, the first indication being scar management.

It is easy to get to study pressure theory. Our pages are full of information and sources that can be utilized to find more studies. Research portals are also full of studies on pressure treatment and its different indications.

Pressure treatment, with medical pressure garments, has very little contraindications. It is generally safe to test it for shorter or longer periods of time.

What is a pressure garment?

Pressure garments are used as a form of medical treatment, which can be used to treat various types of diseases and physiological problems. Users of pressure garments may suffer from e.g. burns, chronic pain, edema, cancer or physical challenges caused by cerebral palsy, autism or hypotonia. Pressure garment is a tight fitting piece of clothing, which generates pressure on a desired body part or the entire body. Therapeutic effects of garments are based on precisely calculated and controlled pressure.

The effects of compression and pressure products are based on a correct level of pressure. In compression products it is progressively declining – it’s the strongest in the distal portions of the body and eases towards the center of the body. The more body the product covers, the more powerful the compression effect is. In garments with a steady, even pressure, the pressure is manufactured uniformly throughout the entire product. Compression socks are manufactured in various compression classes.

Theoretical basis

A custom-made Lymed Animal™ garment has a medically controlled pressure. Lymed Dog™ products have affect the animal’s ability to re-focus and self-appease. Based on studies made within the scope of human medicine, the calming effect of pressure is rooted in strengthening proprioseptics and awakening the deep sensory input. Pressure garments have been used for decades to treat neurological disorders and improve stability. However, knowledge based on scientific research and clinical proof of treatment effects is still limited. Pressure garments (along with other pressure appliances) are usually applied for enhancing sensory perception, aiming at effective and functioning sensory integration.

The function of the supporting garment is based on enhancing proprioseptics of the body, body awareness and deep pressure input. In different disorders of sensory integrations the feeling of pressure in large areas can help to manage the pressure inputs and overcome the feeling of irritation and malaise. This has a favorable effect on the ability to concentrate and generalized feeling of ease.

The theoretical basis of the treatment is the gate control theory (1965, Ronald Melzack & Patrick Wall), a theory based in human medicine. It states that pain signals are not free to reach the brain as soon as they are generated at the injured tissues or sites. They need to encounter certain ‘neurological gates’ at the spinal cord level and these gates determine whether the pain signals should reach the brain or not. In other words, pain is perceived when the gate gives way to the pain signals and it is less intense or not at all perceived when the gate closes for the signals to pass through. This theory gives the explanation for why someone finds relief by rubbing, stroking or blowing air into the injured or painful area. A mild, medical pressure has been noticed to effect the sensation of pain in humans. Pressure treatment is a recognized form of pain management.

Multiple sources indicate post-operative garments to accelerate healing and scar maturation. Pressure treatment is widely used in the aftercare of several surgeries to remove and prevent swelling, bruising and alleviate the pain in the operated area. The pressure treatment also supports rehabilitation by helping regain mobility by removing extra fluids. Lymed Animal™ garments, in post-operative use, will help the animal patient to its feet faster.

Pressure garments are widely accepted, primary treatment for treating the scarring due to burns. The pressure treatment has been shown to thin the dermis. The pressure generated minimizes tissue edema and the division on cells. The scar declines and the collagen realigns according to epidermis. Additional scar treatment products (gel sheets, silicones) can be used alongside with the garments to boost the effects of pressure treatment.

Why custom-made?

Lymed manufactures all animal pressure garments individually, no matter how many legs needs to be covered.

Generally, pressure garments can be chosen from standard-sized products based on client’s measures or they can be custom-made from the very beginning. All Lymed Animal™ products are custom-made. This ensures that the pressure level can be precisely defined and controlled. Research on pressure garments in human medicine indicate that the can only way to meet the objectives of treatment in efficient and safe way without any negative physiological effects, is by using custommade garments.

How to form pressure with garments

The pressure is formed in via the relation of the circumferences of the area that needs to be treated and the garment itself. The pressure is calculated based on Laplace’s Law (a principle of physics that the tension on the wall of a sphere is the product of the pressure times the radius of the chamber and the tension is inversely related to the thickness of the wall). The calculatory pressure might not duplicate itself fully on the living tissue due to the variation of it.

The pressure class is used to define the lowest and the highest pressures between which the real pressure will fall. In custom-made products the pressure class can be more specifically defined compared to standard sized products. This also allows the use of a greater pressure level more safely than in standard products. The real pressure provided by the garment can be measured with a pressure monitor when the garment is in use. The levels of real pressure during an extensive period of use can be monitored during control visits with pressure monitors.

The units used in pressure treatment are called mercury millimeters (mmHg). Different Lymed product groups, both in humans and animals, have either a progressive (compression) or an even pressure. The compression created can be divided to four compression classes (from A to IV). These compression classes are based on the European prestandard ENV 12718/2001.

Pressure levels of Lymed Animal™ -products are defined based on empirical data gathered in experiments, combined with theoretical knowledge on animal physiology and pressure treatment on humans.
