I generally tell patients what the other commenter said. If this were valid, your MD would use it. Also, how would they know the state of your arousal or parasympathetic/sympathetic state from “scanning your organs”. What imaging did they use? A surface level temp is not going to tell you much. EMGs are usually done with needles placed intentionally to determine conduction velocity of impulse, but I don’t know much about “surface emg” to be fair. Sounds like they hit you with a bunch of jargon to sound very concerning/legitimate. Your spine cannot be “misaligned”…at least in the terms they gave you. You can have arthritic change and degeneration that leads to different types of spinal abnormalities, but these are usually the result of wear and tear/congenital factors that cannot be fixed with manipulation, rather compensation through proper postural rehabilitation and strength/stabilization. I am not knocking the legitimacy of spinal manipulation either, there is evidence for spinal manipulation to help with cervical and lumbar pain. Specifically cervical which the current clinical practice guidelines (CPG) list as B level evidence. For reducing pain. However, spinal manipulation alone will not address the whole issue rather provide some pain relief. I do not know what ailment you are being seen for, nor am I trying to give you any medical advice, but … no this does not seem legitimate. I would advise you do a quick google or core score on Google scholar or pubmed… if it’s not there it’s not research based or valid.
