Another article that is finding degenerative diseases as being multi-factorial.http://www.immed.org/NeuroDiseases/SIBI ... havDis.pdf
It's starting to be more common to look at any chronic ailment as a combination of issues when the 'problem' persists.
I see that spinal alignment issues are looked at more often in this manor now. If there is a, for example bacterial infection present at the time of an injury the likelihood of an ongoing disease process and extended injury repair process is expected. The repetitive injury site issues over years are being seen as more than coincidence. The development of other dx'ed issues at the site are common yet misunderstood.
If there are diseases that are blood born for instance, are present in the MONO factorial approach to rehab from injury, long term wellness will continue to fail, imo.
Interesting thought came to mind, in Chinese Medicine were there Double Blinded, Placebo controlled Tests in Research and Testing or purely an acceptance of outcomes.
It's kind of like the acceptance in European cultures for Religion and the opposite non-acceptance of 'God' in non-European Cultures.
One test method for one facet of life and not for the other! Medicine versus Religion!
