But we found that if anybody had a limited result during the trial when we gave them escape therapy with the active procedure, we were able to get a better result when we tried harder to be a bit more meticulous at getting the lesions onto the nerve, and people were able to get a response thereafter. All we are doing is disconnecting the joint from the nervous system like a local anaesthetic. So we're looking at two-thirds of a year. But our other work since and before, outside the actual double blind trial, indicates somewhere around a 12 month period of pain relief. Our record is three years.
Some patients get around nine to ten months.
So there are more people with neck pain that will benefit as a proportion than people with back pain. As I've said to you before, most of back pain is due to disc problems and we don't have a procedure like this for disc pain. There are technical limitations, the joints and nerves are harder to get to with the apparatus available, and there have been a lot of studies using essentially sham procedures. I spent 20 years chasing shonky procedures that had a good idea but wrong anatomy or wrong technology, just a little bit off. And so we haven't perfected the lumbar operation for low back pain.
