I've worked in Physical therapy for 13 years now. All inversion tables do is put traction on the spine. If you have a slipped disc this can alleviate some pain temporarily and certainly is better than popping advils or tylenols all the time. If you use it start with some heat on the back (lower or upper depends where your pain is) for 15 mins then use the inversion table for about 10 - 20 mins. After that rest by laying supine or reclined in a chair for another 10-20 mins. To have any long term affects with slipped discs you should try using it at least 3 - 4 times a week. That's the best advice I can offer.
