For some patients, this can contribute to chronic pain, recurrent instability, reduced function, and disability. This study focuses on adults with hypermobile Ehlers-Danlos syndrome (hEDS), hypermobility spectrum disorder (HSD), or joint instability after injury who have already completed physical therapy without adequate relief.\n\nThe main question this study aims to answer is whether the first treatment step, dextrose prolotherapy, can reduce pain by 40% or more two weeks after the second injection.\n\nParticipants will receive treatment in a step-by-step sequence, based on their response:\n\nStep 1: Dextrose prolotherapy A dextrose-based injection used to stimulate a healing response in ligament, tendon, or joint-supporting tissue.\n\nStep 2: Platelet-rich plasma (PRP) An injection prepared from the participant's own blood, designed to support tissue repair and recovery.\n\nStep 3: Doxycycline injections A low-dose injectable treatment used in this study to help protect joint-supporting tissue. It is not being used to treat infection.\n\nAlternative option: Hyaluronic acid injections An injection into the joint that may be offered if the earlier treatment steps do not provide enough improvement.\n\nEach treatment step begins with two injections, given approximately two weeks apart. If a participant improves by 40% or more, they may continue with that treatment pathway. If they do not improve enough, they may be offered the next step in the study.\n\nParticipants will be followed for up to 12 months, with study visits used to monitor pain, function, treatment response, and safety.",[27,28,29,30,31,32,33,34,35,36,37],"Ehlers-Danlos Syndrome Hypermobility Type (hEDS)","Ehlers-Danlos Syndrome (EDS)","Joint Hypermobility","Joint Instability","Hypermobility Spectrum Disorder","Chronic Pain Syndrome","Musculoskeletal Pain","Sprain","Subluxation","Dislocation","Craniocervical Disfunction",[39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,35,54,37,55],"prolotherapy","dextrose prolotherapy","platelet-rich plasma","PRP","doxycycline","regenerative medicine","joint hypermobility","hEDS","hypermobile Ehlers-Danlos syndrome","viscosupplementation","hyaluronic acid","step-care","ligament instability","MMP inhibition","dislocation","CCI","Craniocervical instability","NOT_YET_RECRUITING","2026-07-08",{"date":59,"type":60},"2026-07-10","ACTUAL",{"date":62,"type":20},"2026-07-15",{"date":64,"type":20},"2028-12-31",{"name":66,"class":67},"Manhattan Pain Medicine, PLLC","OTHER"]
