I understand that this is all debate able, but I am trying to interpret Sarno's theories appropriately. I haven't been able to figure out if CTS is (in Sarno's mind) solely a manifestation of mind body disorder, or a physiologically based disorder that can be imitated by TMS. I believe the analysis that CTS and other disorders are considered hereditary may be more a result of accessibility to the brain. People who had parents with CTS have been more exposed to the concept of the disease and even more "conditioned" to expect it to occur to them down the line. As internal stresses build, the uncobscious chooses a manifestation that makes sense to the conscious mind. Whether creating symptoms that coincide with an individual's keyboard/mouse usage, creating a back pain when the individual is performing barbell squats, or creating a pain based off of the knowledge base of that individual, the process is all the same. I am also wondering if all Repetitive Strain Injury is truly mindbody based. As Sarno said, "we are not made of paper maiche (sp?)". Conventional medicine cannot explain why RSI is more common in the US than is less developed countries where individuals are more active and proper nutrition is less accessible.
