Brief summary

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.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Joint hypermobilityOne-time assessment at baseline (Day 0, at the inclusion visit).Joint mobility will be assessed according to the Beighton score using a goniometer.
5-part questionnaireOne-time questionnaire at baseline (Day 0, after clinical examination).Participants over the age of 18 will also complete the 5-part questionnaire regarding historical hypermobility.

Secondary

MeasureTime frameDescription
Joint painOne-time questionnaire at baseline (Day 0, after clinical examination).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.'
Temporomandibular joint problemsOne-time questionnaire at baseline (Day 0, after clinical examination).Screening questions regarding temporomandibular joint problems. The short version of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) classification system will be used.
Pain drawingOne-time questionnaire at baseline (Day 0, after clinical examination).Participant marks areas of perceived pain on a schematic human body figure.
