Additive Effects of Interoceptive Training to Physiotherapy in Functional Movement Disorders (interoPTfmd)

Sponsor: Charles University, Czech Republic

Summary

Functional movement disorder (FMD) is a common source of neurological disability that imposes a significant financial burden on healthcare systems. However, the heterogeneous manifestations of FMD and numerous associated non-motor symptoms, often fluctuating over time, present a challenge for developing effective treatment pathways. Although increasing evidence supports the efficacy of physiotherapy for FMD, the lack of predictors of treatment outcomes remains a significant obstacle to effectively managing FMD. The main hypothesis of this project is that abnormalities in interoceptive processing are responsible for variability in motor and non-motor symptoms and response to physiotherapy. Interoception describes the afferent signalling, central processing, and mental representation of internal bodily signals. We hypothesize that worse performance on interoceptive tests will be associated with greater severity of motor and non-motor symptoms and worse quality of life. We also expect that patients with worse interoceptive performance and associated non-motor symptoms such as pain will particularly benefit from treatment techniques modulating interoception, such as specific breathing techniques. Therefore, to test our hypotheses, in this project, we will study interoceptive and attentional abnormalities of FMD and identify predictors of the effect of physiotherapy and interoceptive respiratory training.
