Question: How effective is this on the thoracic (middle) spine? I get mid and lower back pain. I tend to motion sickness so I am concerned about inversions.
Document: Unfortunately it didn't work well for me. I suppose it is good for stretching lower back, but probably not as good for middle part of the spine (thoracic). At least for me. It bends me inward, while I feel much more relieved if something / someone unbends me: this helps to straighten the spine. Lat pulldown exercises actually help me a lot.
It really is strong and well made.It comes with an instruction book and a cd. It is very easy to use, and I feel relief right away. I can really feel the stretch in my spine from hip area to the mid shoulder area. I've never experienced anything like this.I tried inversion tables, but I get motion sick when I hang upside down, so it doesn't work for me. And I can't afford the cost of going through multiple back traction therapies.Thank you for bringing this product to the US!UPDATE: 2013I'm still using the NUBAX, and the "machine" is still in pristine working order.
I've needed an inversion table or inversion boots for many years to reduce the pain of facetic arthritis and asymmetric compression of the cartilege in my lower spine. At 74 neither was convenient and both were intrusive in the house. I took a chance on the Nubax and it does everything I wanted. A few minutes twice a day keeps my back brace in the drawer. I get an extra stretch by pulling up on the lower frame which is very effective but not mentioned in the Nubax literature or DVD. The assembly was straight forward but the interior frame was too wide to fit inside the lower frame which required a few taps with a 5# single jack out in the driveway.
I did not want to get out of the Nubax. It is the first time I have been pain free in 7 years. And, the ease of motion remained for a while after getting out of the Nubax. I feel it helped to open the spine and it helped to relax the muscles.I do not know that anything will give me the freedom of movement that I had before my back injury, but so far the Nubax is the best thing I have found. It is easy and quick enough that I will use it multiple times a day, which all of the traction devices recommend for optimal results.
Kudo's and thanks to whoever dreamed up this clever and effective design. As you begin to get acclimated to the machine you will intuitively learn how subtle shifts in you body position can increase/decrease tension in your back and isolate different sections of your spine for treatment.I'm holding my review at 4 stars for because I'm only a few weeks in. I'll update again as my treatment continues. For now I can definitely say if you are doing spine decompression and it's helping you - this device will help you too.
I had an L5 surgery in 1987, and have been dealing with chronic back pain for decades. After spending six weeks with the DRX9000 back stretching treatment with an MD costing over $5k earlier this year, I am willing to try just about anything.I hit a pothole with a motorcycle in Oct 2008 and have never recovered from the impact my back incurred that day. I spent nearly a year searching for help from the medical profession, only to be told you can not operate on nor fix an issue like this of the thoracic spine.18 MRI's since 1986, 4 just in 2009 have shown a fused neck, 6 bulging discs, one fractured vertebra and no disc at L5.
I have herniated disks in both my lumbar and my thoracic regions. I stood in a line one day for more than and hour and closer to two and as a result, my lower back was in agony for six months straight. I found by accident that some ad hoc traction was bringing me some temporary relief and I decided to research and get some kind of traction device. I had looked at traction tables but some very positive reviews of the NuBax Trio led me to give this device a try. I'm glad that I did.
Less that one week's use and my lower back pain was gone completely.I have been using this device for several years now occasionally when my back starts to hurt. My thoracic pain is much different but this device does provide some relief. When I use it daily, it does help provide thoracic pain relief.I'm 6'4" and I do not have any problems using this with my height. I would recommend that you learn how to properly extract yourself as this can actually pull your lower back muscles if done wrong. The correct way to extract yourself is to use your hand on the floor and push your upper body up.
The left shoulder pad does not fit into the cross bar, i did not receive the 2x nylon washers and the 4x black concave washers that describes the user guide. I have the inversion table Teeter Hang Ups EP-550, The Hammacher Gentle Motion Standing Back Stretcher (almost the same than this) and many other devices, and i think this Nubax Trio Back Pain Reliever is the most expensive with the lower quality that i've ever buy. The Hammacher is cheaper and give better results with no damage in your knees. Low Low Low  quality, buy any other equipment and compare.
The stretch before bed is vital because apparently it lets your back stay loose throughout the night without gravity compressing your spine. When time permits, I use the Nubax when I get home from work or at midday if I'm home.6- Concentrate on loosening your back while you use the Nubax, and try to concentrate your stretch on your lower back. It took me while to get it right, and music or an iPod may help. You'll notice yourself slowly sinking lower and lower throughout the exercise as you loosen up.7- Drink lots of water, apparently it helps to hydrate your discs in your spine, and improves disc healing (I was told this by a chiropractor and by my orthopedic surgeon).OTHER THOUGHTSLike most people have noted, the device itself is pretty simple, and the total sum of the materials is probably not more than about $50.
Answer: yes
