An observational study in Anorexia Nervosa, Atypical and Anorexia Nervosa, sponsored by Vastra Gotaland Region. Enrolling by invitation at 1 site in Sweden. Open to female participants aged 13 Years to 25 Years. Per ClinicalTrials.gov, last updated 2026-08-25.
Sponsored by Vastra Gotaland Region · Observational
The purpose of this study is to examine the frequense of generalized hypermobility and pain in patients with Anorexia Nervosa. The study further explores two main questions: (1) whether generalized hypermobility may be an explanatory factor for pain in some patients with Anorexia Nervosa, and (2) whether temporomandibular joint problems (such as instability, pain, difficulties opening the mouth, locking, or clicking) contribute to eating difficulties in certain individuals with Anorexia Nervosa.
Patients with eating disorder diagnosis Anorexia Nervosa, who are either currently in treatment or awaiting treatment at the Eating Disorders Center for children and young adults in Gothenburg, will be invited to participate in the study. During a single examination session, the patient's joints will be assessed to determine whether generalized hypermobility is present. At the same visit, the patient will answer questions regarding possible bodily pain and any temporomandibular joint problems. Joint mobility will be examined and assessed by a physiotherapist at the clinic. The examination follows a standardized protocol for assessing joint mobility and includes the assessment of nine specified joints.

Joint hypermobility
Joint mobility will be assessed according to the Beighton score using a goniometer.
Time frame: One-time assessment at baseline (Day 0, at the inclusion visit).
5-part questionnaire
Participants over the age of 18 will also complete the 5-part questionnaire regarding historical hypermobility.
Time frame: One-time questionnaire at baseline (Day 0, after clinical examination).
Joint pain
The Numeric Rating Scale (NRS) is a self-assessment tool used to describe the patient's perceived pain intensity. The patient marks the intensity on a line with eleven points, ranging from 0 to 10. The endpoints represent 0 = 'no pain' and 10 = 'worst imaginable pain.'
Time frame: One-time questionnaire at baseline (Day 0, after clinical examination).
Temporomandibular joint problems
Screening questions regarding temporomandibular joint problems. The short version of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) classification system will be used.
Time frame: One-time questionnaire at baseline (Day 0, after clinical examination).
Pain drawing
Participant marks areas of perceived pain on a schematic human body figure.
Time frame: One-time questionnaire at baseline (Day 0, after clinical examination).
