I think so in a whole package of treatment. Here is what my guy does to me: First is like 10 minutes on TENs therapy. I love that and even have one at home. Then I go in a room and get the big vibrator massage all over my back. Then he puts his hand on a few spots on my back and releases the lower half of the table. He lowers my legs the swings them side to side. Then back up then down and moves them again with is hand on a different part of the back. I never asked but its just a stretch that decompresses the spine too. With the TENs, massage, and then this the muscles are pretty loose. Then he adjusts me. Feels great.
As far as effectiveness I say its great. I cam into his office in bad shape (3 nights before I could barely walk) 3 weeks later of 3 times a week sessions and i started training at 10thp

. i did twice a week for two weeks then once a week for two weeks and now I just go when I feel like it. I felt fine last month and dint go.
I drink at least 75oz of water a day and stretch all the time to keep it loose though.
