The Ehlers-Danlos Society” funds research at all stages, scopes, and scales. Our microgrants provide funds to early stage investigations primarily designed to provide proof of concept for larger studies. Current investigations include research into chronic pain, dentition, body awareness therapy, and TNX deficiency.
Body Awareness Therapy as Treatment for Chronic Pain
People with Hypermobility Spectrum Disorder (HSD) often have pain, coordination problems, and low tolerance to activity and exercise. Body awareness training, such as Feldenkrais, may help people manage these challenges. This pilot study will have a convenience sample of 10 individuals with symptomatic Hypermobility Spectrum Disorder (HSD) participate in a 12 session Feldenkrais program to teach body and movement awareness. Feldenkrais is a form of movement retraining aimed at improving efficiency and reducing muscle guarding and pain during movement. It uses guided visualization techniques during small movements to help the individual explore using stabilizing muscles in a safe range of motion. It is a type of mindful movement that has been used successfully for managing chronic pain. The goal of this pilot study is to see whether participants in the Feldenkrais program report decreased pain, improved function, and improved self-efficacy (confidence in their ability to take care of themselves). If there are improvements in any of these outcomes, we hope to be able to determine whether these changes are related to improved self-awareness (interoception) or decreased fear of movement (kinesiophobia). Another potential benefit from this research will be to establish a research design framework for clinicians interested in performing similar pilot studies using other body awareness therapy approaches such as Pilates, Tai Chi, etc.. Clinician-led pilot studies such as these can lead to future, more definitive randomized control studies.

Accessing Chronic Pain in Pediatric Patients with EDS/HSD
Multidisciplinary pain management is recommended as best practice to not only reduce pain, but also to improve functional ability, when providing care to children and adolescents with chronic pain. As children with hypermobile Ehlers Danlos Syndrome (hEDS)/hypermobility spectrum disorder (HSD) have an increased risk of injury and prolonged recovery time post injury, standard multidisciplinary pain programmes may not be as effective for children with hEDS/HSD. However, we currently don’t know if the chronic pain experience and associated symptoms of children with hEDS/HSD is similiar to that of their non-hEDS/HSD peers. We also don’t know if the outcomes from multidisciplinary pain management is different for children with hEDS/HSD than that of their unaffected peers. A better understanding of these differences may assist us to develop tailored multidisciplinary chronic pain management programmes for children with hEDS/HSD.
Children attending the main paediatric chronic pain clinics in Sydney, Australia, have been recruited into this study which is currently underway. We are measuring how many children attending have generalised HSD (G-HSD) or hEDS. Each child completes questionnaires about their pain, fatigue, mental health, and other symptoms at initial presentation and again 6 months later, including their global impression of change and satisfaction with multidisciplinary pain management services. , however children with G-HSD reported significantly lower functional abilities than their non-hypermobile peers. Results of this study will provide critical data to assess the potential need for future studies assessing the efficacy of a hypermobility-specific intervention designed to reduce pain of children and adolescents with G-HSD/hEDS, and allow for immediate translation of findings into current clinical practice.

Dentition, Orofacial Function And Craniofacial Characteristics Of Patients With Ehlers Danlos syndrome
The Ehlers-Danlos syndrome (EDS) is a hereditary disorder affecting the connective tissue and collagen structures in the body and is characterized by joint hypermobility, skin hyperextensibility and tissue fragility.
Several types of EDS have been identified and may affect structures in the mouth including early onset inflammation of the tissues around the teeth, abnormally shaped roots and functional problems in muscles and the temporomandibular joint, which impede diagnosis and treatment. Sleep-disordered breathing (SBD) has recently been reported in EDS and is often associated with specific characteristics of the craniofacial profile. The aim of this Danish study is to examine the teeth, the chewing function, the craniofacial profile and upper respiratory tract of patients with EDS compared to a healthy age and gender matched control group. The hypothesis of the study is that there will be differences in teeth, function, craniofacial profile and upper respiratory tract between patients with EDS and a healthy control group. The results will contribute to a better understanding of the characteristics of EDS and thus improve diagnostics and treatment of EDS. In addition, this new knowledge is relevant for dentists as many dentists meet patients with EDS in their daily clinic.

Understanding Increased Pain in TNX deficient and hEDS patients
In the past 15 years, scientific advances has led to acceptance amongst medical professionals that bowel symptoms are very common in hypermobility related disorders, in particular, the hypermobile Ehlers-Danlos (hEDS) subgroup. This group of patients have a problem with the extracellular matrix (ECM) which is the scaffold that keeps joints and organs intact. Patients with hEDS experience symptoms similar to those who have Irritable Bowel Syndrome thereby constituting a strong link between the two types of conditions. If we can find the basis for this link, we can design or optimise medications to manage the bowel symptoms that address the main abnormality in the tissues that causes these disorders. Thus it will be easier to intervene with patients susceptible to abdominal (tummy) pain constipation and/or rectal prolapse using existing or novel treatments. Finally, it will make a major difference for patients to know what is the root of their problem, which is not currently the case in the majority of patients with functional gut disorders (where cause is not known).
Previously we have characterised a type of ECM tissue called Tenascin X (TNX) in the mouse and human gut and found that it is important for gut function. We now want to understand why abdominal pain is common in patients with hEDS and in TNX deficiency. If a clearer picture of why pain is common in patients with connective tissue disorders is found, it would pave the way for better diagnosis and treatment. We have obtained a TNX knockout mouse (where the TNX gene has been removed), and developed purpose-designed techniques and have investigated TNX role in several gut functions. In particular we have studied how TNX influences the function of nerves that control sensation and movement of the gut. For this grant we would like to use TNX-KO mouse model to explore the reason for increased pain in TNX deficient and hEDS patients. We have obtained stomach and gut biopsies from patients diagnosed with hEDS, which we will study to see how different pain nerves look compared to biopsies from normal people.
