Proprioception and Interoception in Patients With Fibromyalgia

Summary

The goal of this observational study is to learn about interoception and proprioception in patients with fibromyalgia. The main questions it aims to answer are:

* Is there a significant difference in interoception between patients with fibromyalgia and healthy controls?
* Is there a significant difference in proprioception between patients with fibromyalgia and healthy controls?

The participants will perform:

* The respiratory occlusion discrimination task
* A postural control task where the effect of muscle vibration on center of gravity displacement is examined
* The head repositioning accuracy task

The participants will also fill out different questionnaires.

Researchers will compare healthy controls to see if there is a significant difference.

Conditions

• Fibromyalgia

Interventions

OTHER

Interoceptive accuracy measurement

Interoceptive accuracy will be measured using the Respiratory Occlusion Discrimination Task (ROD task; Van Den Houte et al., 2021). The ROD task measures how good subjects are at distinguishing the lengths of short (max 620 milliseconds) inspiratory occlusions (or respiratory interruptions).

OTHER

Interoceptive sensibility measurement

Interoceptive sensibility will be measured using two self-report questionnaires, the Interoceptive Sensitivity and Attention Questionnaire (ISAQ; Bogaerts et al., 2022) and the the Three-domain Interoceptive Sensations Questionnaire (THISQ; Vlemincx et al., 2021)

OTHER

Interoceptive awareness measurement

Interoceptive awareness will be measures using a visual analogue scale (VAS)

OTHER

Proprioceptive accuracy measurement during postural control

The effect of muscle vibration on center of gravity displacement (center of pressure or COP) will be examined. Muscle vibration of the m. triceps surae ("ankle" muscles) and the lumbar multifidus ("back" muscles) (Johanson et al., 2011; Brumagne et al., 2008; Claeys et al., 2011; Cleays et al., 2015) will be used to examine the role of proprioception during postural control.

OTHER

Proprioceptive accuracy measurement of the neck

The head reposition accuracy task will be carried out to assess proprioceptive accuracy of the neck. The most commonly used procedure is the head repositioning accuracy to neutral head position (HRA-to-NHP), first described by Revel and colleagues (1991).
