The stitching quality and finish work on the DDS 500 and its Velcro fasteners was the top of the class. We found no rough seams and we are particularly fond of the stretchy auxiliary strap which helps patients adorn the brace correctly. The craftsmanship of the “8-inch” extension piece is identical to the craftsmanship of the DDS 500 brace, well made. The inner lining of the DDS 500 is 100% cotton lending to a comfortable overall wearing experience.
Definitely the best of the pack, the DDS 500’s pump is heavy duty, features a sleek, easy-to-grip design, pumps notably easy and has a clearly marked, easy-to-read pressure gauge so the user can easily tell when to stop pumping. On average it took us about 13 pumps to achieve the desired PSI. The spring-loaded clamp is easy to attach as well. The DDS 500 also comes with a 6 inch extension air hose, simply unscrew the air valve off, screw on the extension air hose in its place and you have as an option a longer air hose to work with, this is ideal for patients who lack manual dexterity and need to get a visual or for patients who require more working room to attach the hand air pump spring loaded clamp, once the patients is done inflating the brace they simply remove the spring loaded clamp and tuck the air hose in between their body and the brace.
The foot pump is very similar to those of Braces “A” and “D”. It has no read out gauge making it difficult for patients to know when to stop pumping. Also, the pump flips over easily making it unstable for aging patients or for patients suffering from low back pain, sciatica or have limited leg mobility which would now be required to do a repetitive pumping action to inflate the brace. We do like the extended air hose but don’t like that there is no place in which to tuck the end of it when wearing
We found the Velcro fasteners and the stitching of Brace “F” to be equal to that of Braces “A”, “B” and “D” coming from the same factory of course. Once again this also has similar plastic bases supporting the air valve mechanism on the inside of the brace which we feel can protrude into the patients skin even though it does have rounded corners and is relatively shallow in profile.
The DDS Panels are form fitting just as most of the others are. The front panel attaches via a Velcrostrip. The rear panel has two slots on either side through which the brace threads through.
The lumbar curve is where the DDS 500 simply outshines its competitors. It is the only brace ofthose tested that has any degree of lumbar curve designed into the belt as shown in the photo above.Not only does this design feature enhance the anterior curvature of the lumbar spine promoting proper lordodic curvature increasing the brace’s decompression effectiveness, the primary reason for the lumbar curve or concave design engineered into the DDS 500 brace is that it is designed to target the L5-S1 area of the spine, which is where 86% of all low back disc issues occur.
The rigid panels for Brace “F” are the typical hard molded plastic with large threads on each side of the posterior panel and a large oval shape in the center. The anterior panel has a Velcro strap rivets on all 4 corners. The rigid panels are basically identical to that of Brace “D”, once again coming from the same factory in China...we think.
Brace “F”, like the other look-a-like Spinal-Air Decompression braces on the market, lacks any kind of lumbar curve, which significantly aids in overall distraction force and ultimately effectiveness. We see this as a major design flaw… again.

The DDS 500 is the original spinal air decompression lumbar brace and it is without question still the best. Its material and craftsmanship are top notch, its pump is the most user friendly and we found it to be the most comfortable to wear. The most impressive design feature of the DDS 500 is it lumbar curve which allows it to form fit to the natural curve of the human spine promoting proper lordodic curve as well as maximizing the brace’s distractive force, which is the purpose of the brace to begin with.
Brace “F” Air Traction Brace is the last of the 4 braces in this report which appear to be made by the same manufacturer in China. Like the Braces “A”, “B” and “D” they lack the ever so important lumbar curve and its seemingly lighter/less durable material and craftsmanship. Brace “F” does have a longer air hose which makes attaching the air hose easier, however once again there is no place or nothing to secure the air hose to, therefore it just dangles.
