Background: The aim of clinical study was to investigate and compare impact of robotic assisted therapy by using virtual reality to classical kinesiotherapy improving the function abilities of upper limb. Patients and Methods: 60 patients were divided randomly into two groups. Main group completed a robotic assisted therapy and comparative group completed classical kinesiotherapy. The patients with impaired upper limb were from 6 to 17 years old and all underwent twenty therapies. Results: Statistically significant results were obtained in the patients who completed a robotic assisted therapy by ArmeoSpring® in all Fugl-Meyer Assessment of Physical Performance, the best improvement (p = 0.000) in all tested blocks, apart from block H, where was the statistical significant (p = 0.002). Comparative group of the patients achieved statistically significant results only in testing of the Fugl - Meyer in block of sum of motor function A-D (p = 0.009). In other blocks were the results without statistically significant p ≥ 0.05. Conclusion: The patients with cerebral palsy are statistically more effective from robotic assisted therapy by using virtual reality for the improvement of function ability of paretic upper limb, than those who completed the classical kinesiotherapy.

Abstract Objective: Exercise with virtual reality (VR) is a novel approach to the promotion of health and the components of fitness. Our objective was to investigate the effects of exercise with VR on physical performance, mental fatigue, and physical fatigue in single-stage aerobic and anaerobic running.Materials and Methods: Twenty physically active, healthy, age-matched male university students executed the exercise test in aerobic and anaerobic groups in two separate sessions of VR (first-person perspective in a simulator) and non-VR (traditionally in the laboratory). The simulated environment was a graphic tunnel route. The aerobic and anaerobic groups engaged in the Bruce protocol and anaerobic speed test, respectively. Exercise test duration, blood serum lactate concentration, rating of fatigue (ROF), and heart rate were recorded at the end of both sessions.Results: Intragroup comparisons using the dependent t-test indicated that the exercise test duration significantly increased in the VR session of the anaerobic group compared to the traditional method considering the effect size (t7=0.804; P=0.804). However, the test duration remained unchanged in both sessions of the aerobic group (t9=1.373; P=0.203). Serum lactate concentration significantly decreased in the VR session compared to the non-VR session in the aerobic group (t9=4.734; P=0.001) and anaerobic group (t9=2.321; P=0.045). ROF and heart rate of the aerobic and anaerobic groups remained unchanged in both sessions.Conclusion: The findings indicated that as an alternative for improving physical performance in exercise, running with VR in an imaginative virtual environment decreased physical fatigue in a single stage of aerobic and anaerobic running.

Processing Mechanisms

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.

Neue Technik

Fragestellung: Die dieser Untersuchung zugrunde liegende Frage war, ob das angewandte Ausbildungskonzept geeignet war, um am Beispiel der Einführung der laparoskopischen Cholezystektomie eine neue Operationsmethode in einer universitären Ausbildungsklinik mit einer grossen Anzahl Chirurgen zu etablieren. Patienten und Methodik: Seit Einführung der ersten laparoskopischen Cholezystektomie wurden alle Cholezystektomien während zwei Jahren (Mai 1990 bis Mai 1992) prospektiv erfasst. Ein Ausbildungskonzept wurde gewählt, bei dem jeweils ein Operateur durch einen Tutor geschult wurde und so 15 konsekutive Eingriffe durchführte, um dann die Technik einem weiteren auszubildenden Chirurgen zu instruieren. Resultate: In zwei Jahren wurden 355 Patienten cholezystektomiert. 60% der Operationen wurden laparoskopisch durchgeführt oder begonnen. 40% der Operationen wurden offen durchgeführt. In den ersten zwei Jahren konnten 13 Operateure (durchschnittlich 16 Operationen / Operateur , range 1 - 60) in die neue Technik eingeführt werden. Es traten keine schweren Komplikationen, insbesondere keine Gallenwegsverletzungen in dieser Einführungsphase auf. Diskussion: In der Literatur wird dieses Vorgehen bei der Einführungsphase seit 1992 wiederholt vorgestellt, diskutiert und empfohlen. Zwischenzeitlich gibt es Richtlinien von Fachgesellschaften und nationalen Institutionen, welche die Ausbildung zur Ausführung neuer chirurgischer Techniken reglementieren. In den letzten Jahren verlagern sich die ersten Ausbildungsschritte in Richtung Trainingskurse an skill-stations und virtual reality Trainer. Schlussfolgerung: Das beschriebene Ausbildungskonzept bewährte sich in der Einführungsphase der laparoskopischen Cholezystektomie zu Beginn der 90er-Jahre.
