My neighbor used one and really like it, as it helped to strengthen his abdominals. However, I would be very cautious recommending anything to help your wife's back without knowing any details as it could also potentially cause more damage or pain. I would check with her Dr., if you haven't already done so, before buying anything like this.
Also... you will probably get more feedback if you move this thread to the pub.
oh my! looks painful....
Wifey was injured as a teenager doing gymnastics and also from having carried 4 kids to full term. Nothing terrible like drastic injury but still she suffers and any relief we can give her, I'd try. We do have a fantastic chiropractor here who has been awesome! Wifey sends her pregnant patients to him also... I found a table on Craigslist that we are going to purchase. Supposed to be the best brand (Teeter). We'll give it a go!
I am going on 8 weeks post operation on my neck. I had a C3/C4 & C4/C5 anterior cervical discectomy and fusion. I put off surgery for over 2 years while my daughter was finishing up playing ball at UT. I had severe stenosis of the spinal cord and the 2 years of headaches, neck pain, numbness and tingling disappeared after I woke up from recovery.
I had 4 herniated discs but the doctor chose to only have surgery on the 2 worst discs which will leave me a potential need for a future surgery (Doctor felt a 10 to 15% likely hood that I will need a future surgery.)
I was hesitant to have the surgery but very thankful to have had it done and on my way to recovery.... my recommendation would be consult a surgeon and then get a second opinion. The procedures have come along way in just the past couple years!
