“…In addition to standard physiotherapy, there are more and more attempts to use complementary methods of therapy for people with PS in order to accelerate and increase treatment effects. Studies show effectiveness of the use of Robotassisted Gait Training (RAGT) robots to assist walking, standers, Visual Feedback (VF) and Virtual Reality (VR) [16,28]. One of the possibilities of supporting therapy of patients with PS is the use of a stander.…”

The consequences of damage to brain structures often includes various types of perceptual and motor disorders. One of them is Pusher Syndrome (PS). It is defined as a disturbance in the perception of the body position in the frontal plane, which in turn makes it difficult to maintain a correct vertical posture. It occurs most often in patients after a stroke of the right hemisphere of the brain, in the posterolateral region of the thalamus, and its frequency is estimated at about 9–50%. However, it is still a little-known syndrome and too rarely diagnosed. Correct, early diagnosis of pusher syndrome and the introduction of appropriate physiotherapy allows us to shorten the patient’s rehabilitation time and speed up his/her recovery. The objective of the study is to present the principles and possibilities of therapy for patients with pusher syndrome.

“…After testing the applicability of the new device in the present study, we are confident that the use of the TRD in pusher patients will actually have therapeutic success. The reason for this is that our group has already been able to show in a single case study, albeit with using VR technology, that the principle used here, namely presenting the patient with the visual environment in a tilted state, was able to reduce pusher symptoms (Nestmann et al, 2022). The authors used a three-dimensional virtual environment (a scene of a beach with a footbridge) that could be explored by wearing a HMD.…”

“…The use of digital media has become increasingly popular to create virtual environments that enable a variety of therapeutic and rehabilitation scenarios for patients suffering from various limitations (Kato, 2010;Primack et al, 2012). So-called 'games for health' include, for example, the rehabilitation of aphasia (Bu et al, 2022), motor control after stroke (Shah et al, 2019;Standen et al, 2017), disorders such as spatial neglect (Huygelier et al, 2020;Knobel et al, 2021;Morse et al, 2020;Stammler et al, 2023), or pusher syndrome (Nestmann et al, 2022).…”

Pusher syndrome is a disorder of postural control after stroke. Patients show a mismatch in their perception of (almost preserved) visual and (pathologically tilted) postural verticality. In order to reduce this mismatch, we developed a novel head-mounted Tilted Reality Device (TRD). It presents patients visual footage of their actual surroundings but tilted to one side rather than upright. We investigated its usability and possible limitations in its use for the treatment of pusher patients in two samples of healthy participants with an average age of 26.4 years and 63.9 years respectively. Individuals from both age groups showed similar levels of tolerance to prolonged exposure to the tilted visual environment for an average of 40.4 minutes while walking around in the hospital. The TRD was found to be comfortable and not frustrating whilst wearing, but somewhat challenging in terms of technical handling, particularly for older participants. At the end of the maximally tolerated exposure time participants of both groups experienced some feelings of discomfort, like dizziness or increased stomach awareness, which disappeared rapidly after terminating TRD exposure. Our TRD appears to be a practical device especially for an older population, like pusher patients. While users must be aware of the possibility of side effects, these should be balanced against the benefits of future use for rehabilitation purposes.

Zusammenfassung: In der neu überarbeiteten Leitlinie wurde das bewährte Explorationstraining bei der Behandlung des Neglects durch Vorschläge zum therapeutischen Vorgehen für verschiedene Schweregrade des Neglects und eine damit einhergehende zeitliche Reduktion ergänzt. Darüber hinaus erfährt es derzeit interessante Erweiterungen durch den Einsatz von „Augmented Reality“- und von „Virtual Reality“-Verfahren. Weiterhin empfohlen zur Behandlung des Neglects wird das Training mittels langsamer Folgebewegungen zur kontralateralen Seite und mittels Nackenmuskelvibration. Unter den nichtinvasiven transkraniellen Hirnstimulationsverfahren hat sich das kontinuierliche Theta-Burst Stimulation (cTBS) -Protokoll in Bezug auf die Neglectsymptomatik als wirksam erwiesen, wenn es mit mindestens einem weiteren Trainingsverfahren (z. B. Explorationstraining) kombiniert wurde. Zur Behandlung des Pusher-Syndroms wurden Visuelles-Feedback-Training und robotergestütztes Laufbandtraining von unterschiedlichen Gruppen erfolgreich eingesetzt. Die Situation ist problematischer bei jenen Verfahren, die zur Behandlung der weiteren in der Leitlinie besprochenen Störungen der Raumkognition (Bálint-Syndrom, Simultanagnosie, optische Ataxie, Störungen der visuell-räumlichen Wahrnehmung, visuokonstruktive Störungen, topografische Störungen) eingesetzt werden. Hier dominieren Einzelfall- bzw. Kleingruppenstudien. Die Auswertung einzelner methodisch hochwertiger und gut dokumentierter Therapiestudien bietet derzeit die einzige Grundlage zur Ableitung von Empfehlungen für die Behandlung dieser Gruppe von Störungen der Raumkognition.
