There are eight different sizes of the DDS Double from size Small to size 5 XL, which will accommodate a torso circumference measurement ranging from 25” to 52”. The DDS 500 brace has 10 sizes from size Small to size 7 XL, these sizes accommodate a torso circumference measurement ranging from 25” to 59”. When measuring your patient for the brace, the measurement needs to be taken at the most protruding part of the patient’s “torso”, which is usually level with the patient’s naval.

Although each brace has its optimal recommended sizing, there is about an inch of play on each end of the measurement. Example: size Large is a 33”- 35” optimal fit; however the brace will extend from 32”- 36” (plus or minus). Once you determine the measurement, you may refer to the measuring chart that is on the packaging of the brace for the correct size brace and panels.

Please keep in mind that we do have an 8” extension piece (additional accessory) available for both the DDS Double and the DDS 500. This extension piece is ideal for patients who have gained a few pounds and no longer fit into their brace, or for patients who are being measured and fitted for the very first time and have put on a few pounds (due to their recent situation with back pain) and plan on losing the weight they recently gained. Such patients can be fitted in the next size smaller brace, or even two sizes smaller (depending on how much weight/inches they intend to lose) and given the extension piece to use until they lose the weight and can fit into their brace without the need of the extension piece.

NOTE: In the case of the DDS Double, two extension pieces are required.

Disc Disease Solutions, Inc. is truly the original and only company that offers the patented expandable air-distraction lumbar system with Vertical Air Pressure Technology (VAP). Flexible in design, the DDS 500 and the DDS Double offers patients a high degree of mobility and support while assisting with their active rehabilitation. During inflation the patented tubeless air cell mechanism of both the DDS 500 and DDS Double models expand vertically, seating down onto the pelvic girdle as its foundation while anchoring up underneath the ribcage pushing upwards, stretching the torso vertically resulting in a decrease of axial loading taking the pressure off of a bulging or herniated disc significantly reducing the pain levels within the Lumbar region.

Wearing and Protocol

Both the DDS 500 and DDS Double are designed for both short-term use on patients with acute conditions such as lumbar sprain/strain, and for long-term use on patients with chronic conditions such as lumbar disc bulge, disc herniation, disc protrusion, disc degeneration, lumbar facet syndrome, etc. Duration of use should commensurate with the duration of pain and discomfort.

Suggested wear time is approximately 4 - 6 hours per day. It is recommended for the brace to be worn during the patients’ most challenging times of the day. Patients may find optimal results by splitting up the time they wear the brace into two or more time periods, such as by wearing the brace for two - three hours in the morning and two - three hours in the afternoon and/or evening.

Valuable Insights

With 99 percent of all LSO bracing on the market today designed to “cinch tight” around the patient’s body applying constriction thus limiting mobility, is it possible for the muscles in the lumbar region to not only avoid dis-use muscle atrophy, but to receive stimulation and strengthen while wearing a brace?

Before We Answer That...
The answer to that question can be found in the results of a clinical study. However, clinical studies can be, by their very nature, difficult to interpret without an understanding of the product being tested and of the purpose and parameters of the test. In the case of the DDS brace, it was tested in Seoul, Korea under the reference name of air brace in a clinical study using the Cybex 6000 Trunk
Extension Flex (TEF) Unit. The Cybex 6000 (TEF) Unit is an isokinetic dynamometer that is engineered to analyze and measure
the values of different muscle groups under different conditions within the human body. It is used by doctors and scientists from
different colleges of physiotherapy and rehabilitation as well as sports physiology departments from around the world.

So how did the Air Brace perform and what does it all mean?

The Answer to Our Question
If the desired goal is for an increase in muscle strength and activity as a result of wearing a brace, the Air Brace performed very well.
This point is clearly illustrated in the graphs found in the Air Brace vs. Muscle Atrophy explanation paper (also found below).
This explanation identifies the before and after endurance characteristics of the trunk extensor and flexor muscles within the
lumbar region before and during use of the Air Brace, concluding that the Air Brace promotes muscle stimulation and activity. It
is important to note that this result is in stark contrast to most all other lumbar supports which limit mobility thereby promoting disuse muscle atrophy resulting in weakness of the lower back and dependency upon the brace.

​Wearing Tips & Suggestions

1. Regardless of the size and/or shape of the patient, the Brace is always positioned on the body the same way.

2. The thin and light weight design enables the patient to wear the brace either over clothing or discreetly under clothing.

3. As the patient is wearing the Brace and has the need for a slight adjustment, the patient can briefly push down on the air valve stem releasing a small amount of air. It is amazing how much of an adjustment even the slightest amount of air released makes.

4. Prior to removing the brace, it is recommended to deflate the Brace first so that the patient’s torso settles down gently.

5. When you are ready to deflate the Brace, unscrew the air valve counter clockwise about 2 turns to release the air. Please advise your patients that although the air valve will unscrew completely off, it is not necessary to do so.

6. Both the DDS 500 and DDS Double are latex free. The exterior material of both braces is made of 100% cotton with a urethane coating, for cosmetic enhancement on the outer surface. Both braces are machine washable using the “gentle cycle” feature of the washing machine.

Fitting The Patient

Position the brace, completely deflated, within the cavity of the patient’s torso, so that the brace is positioned above the patient’s pelvic girdle (hip bones) and under their rib cage, ensuring that the DDS “logo” patch is center with the vertical axis of the torso and over the part of the patient’s torso which protrudes the most (typically at the navel). Secure the brace with all Velcro fasteners, keeping in mind that the brace can be secured fairly snug because as the brace is being inflated it is designed to expand vertically (as opposed to tighten inward)
Maximum recommended air pressure for the brace is 14 psi, which is clearly marked on the hand air pump air pressure gauge.
