Now I do not know enough about your back problems to make a strong suggestion but I do know about mine... I've had a couple of falls in the 16 foot range (you hit the ground at about 20 MPH when you fall that far) one causing a break to two vertebra (L1 and 2) and have had increasing back pain for 30-40 years that I'm sure of (The falls were closer to 45 years ago)
Now Traction (I thought) would help.. I know back belts weight belts and such helped. but I felt Traction would do better.
There are two Traction systems I choose one.
One is the "inversion" devices like the Teeter Hangups.. Big Bulky and ONLY traction
The one I choose is the Dr. Ho Belt.. This is a compresson belt with air bladders YOu pump it up and it provides both compression support AND traction.
Works fairly well... Not 100% cured but I'm way more comfortable now
Will this help you... I do not know, since as I said I don't know the cause of your back pain.
