NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Extracorporeal Shock Wave Therapy for the Treatment of Dysautonomia Secondary to Upper Cervical Instability: A Novel Therapeutic Approach
ABSTRACT
While joint hypermobility can result from various medical conditions, it is most commonly associated with a group of related genetic conditions that affect connective tissue known as Ehlers–Danlos syndromes (EDSs). As there is currently no specific genetic testing for the diagnosis of Ehlers–Danlos hypermobility syndrome (hEDS), diagnosis is strictly made based on clinical criteria, which include physical features such as pain and family history, in addition to a scoring system known as the Beighton Score—a 9-point scale used to measure joint hypermobility—with a score of >4 considered significant. While hEDS often causes chronic muscle and joint pain, the underlying mechanisms remains poorly understood. Dysautonomia, characterized by common symptoms such as anxiety, vertigo, and increased heart rate when standing (orthostatic intolerance), in addition to multiple gastrointestinal symptoms, is highly prevalent among hEDS patients. We hypothesize that hypermobility due to ligamentous instability of the upper cervical spine, C1 and C2, results in impingement of the carotid sheath, the carotid artery and, more significantly, the vagus nerve, thus explaining the myriad symptoms that accompany hEDS. We also propose the novel use of extracorporeal shock wave therapy (ESWT) to treat this instability.
