Inversion tables can work very well for some back conditions. The newer versions of tables are adjustable so that you can control the incline and are not completely upside down. The main issues with inversion tables are that some conditions do not respond well to them or they don't tolerate the position of the inversion table due to blood pressure changes. It would be very difficult for me to explain all the conditions that benefit or don't here so I'm not going to try. The good news is that if you have tried it and it felt good... it's a good thing for you.

If you have blood pressure issues you need to be careful, you can get too much blood pressure in the skull and your body may not know what to do with it (like Mr. S.). Your cardiovascular system can learn to compensate, so the key here is to start out with a lower angle of inversion and short intervals.

The other thing to be careful of is that sustained decompression of the back might feel good at the time but can be very painful afterward. So I would recommend that you start with short intervals of inversion (30 to 60 sec) then take a 20 sec break and repeat. You can increase the interval lengths as you evaluate your tolerance.

Hope that helps.
