Individualized Physiotherapy of Upper Body Functional Movement Disorder - Two Illustrative Cases.

Background: Information on specialist physiotherapeutic treatment for functional movement disorders is scarce. Previous studies focussed on functional gait disorders and availability of descriptions of the practical application especially for other body regions is very limited. Cases: We present two illustrative cases, demonstrating the key elements of physiotherapy for the treatment of functional movement disorders beyond gait difficulties. The individual applicability of the specific core elements of physiotherapy, adapted to the individual needs of each patient, are described. We also explain, how different sensory stimuli can be used to shift attention away from symptoms and thus reduce them. Moreover, we discuss how patients' agency can be encouraged and how this results in therapy key moments, contributing to a sustained improvement of symptoms. Conclusion: Thus, our case series are intended to guide clinicians and therapists alike, to promote disease-specific physiotherapy for this common and treatable neuropsychiatric disorder.

Neural Correlates of Executed Compared to Imagined Writing and Drawing Movements: A Functional Magnetic Resonance Imaging Study.

Objective: In this study we used functional magnetic resonance imaging (fMRI) to investigate whether motor imagery (MI) of handwriting and circle drawing activates a similar handwriting network as writing and drawing itself. Methods: Eighteen healthy right-handed participants wrote the German word "Wellen" and drew continuously circles in a sitting (vertical position) and lying position (horizontal position) to capture kinematic handwriting parameters such as velocity, pressure and regularity of hand movements. Afterward, they performed the same tasks during fMRI in a MI and an executed condition. Results: The kinematic analysis revealed a general correlation of handwriting parameters during sitting and lying except of pen pressure during drawing. Writing compared to imagined writing was accompanied by an increased activity of the ipsilateral cerebellum and the contralateral sensorimotor cortex. Executed compared to imagined drawing revealed elevated activity of a fronto-parieto-temporal network. By contrasting writing and drawing directly, executed writing induced an enhanced activation of the left somatosensory and premotor area. The comparison of the MI of these tasks revealed a higher involvement of occipital activation during imagined writing. Conclusion: The kinematic results pointed to a high comparability of writing in a vertical and horizontal position. Overall, we observed highly overlapping cortical activity except of a higher involvement of motor control areas during motor execution. The sparse difference between writing and drawing can be explained by highly automatized writing in healthy individuals.
