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.
