However, these upper cervial sublaxations were also found among the three patients that did not recall to have ever experienced a kind of head or neck trauma.
I got my doubts when I further read that "The duration between the traumatic event and disease onset varied from two months to 30 years. " I mean, lots of people have sufered from car accidents, sporting accidents such as skiing, horseback riding, cycling, and football; or falls on icy sidewalks or down stairs. I dont have stats for the general population, But I guess that will be a high %.
So I wonder what is the prevalence of the upper cervical sublaxation among the 'healthy population'.
You ask an interesting question which reminds me of the question in relation to the prevalence of CCSVI in the 'healthy population' and the preliminary Buffalo study results. I wonder, though, just because a person doesn't remember a traumatic incident, doesn't mean one didn't happen. The person may have been too young when the incident happened; or disease, trauma, and medications and their side effects may be hindering memories. In a population of 81 patients with MS and PD, I don't think it's too unreasonable for a couple (2.0=81*2.5%) of them to be unable to remember such an incident, but it's a small size for drawing conclusions.(n=81).
Regarding your doubts, in my situation, my worst skiing accident happened ~40 years ago, and my tilted skull and twisted neck (two separate fractures) were only just now discovered and diagnosed by X-rays which I should have had done at the time I was diagnosed. After a lifetime of neuro symptoms and misdiagnoses, I was finally diagnosed RRMS in 2000 and CCSVI in 2010, but I now believe my MS-diagnosing ex-neuro, who moved out of state, was too quick to jump to the MS catch-all diagnosis, and I was too naive and in too rough shape to know better.
Must all upper cervical sublaxations cause neuro symptoms, either soon after or decades after the related accident happened? I wonder about this because not all MS lesions correlate with neuro symptoms, which are called silent lesions -- are there silent sublaxations?
Maybe the answer partially depends on the definition used for sublaxation in the study paramaters/protocol, e.g., "Included in this study will be all sublaxations > 5 on a scale of pain." (I have no idea, just guessing on this one.)
Medical dictionary definition of sublaxation:
"in chiropractic, any mechanical impediment to nerve function; originally, a vertebral displacement believed to impair nerve function.
The original definition is what I thought sublaxation still meant which I guess shows my age. Interesting how the definition has broadened over time.
Interesting discussion all 'round.
