TY - THES A1 - Bakhshayesh, Ali Reza T1 - Die Wirksamkeit von Neurofeedback im Vergleich zum EMG-Biofeedback bei der Behandlung von ADHS-Kindern T1 - Effectiveness of neurofeedback in comparison with EMG-biofeedback in the treatment of ADHD-children N2 - Seit vier Jahrzehnten werden verschiedene Neurofeedbackmethoden bei der Behandlung unterschiedlicher Störungen, unter anderem bei AD/HS-Kindern, eingesetzt. Die Grundlage der Anwendung von Neurofeedback bei dieser Störung besteht darin, dass die Kinder Auffälligkeiten in ihrem EEG zeigen. Dort treten im Vergleich zu unauffälligen Kindern vermehrt Theta-Gehirnwellen und weniger Beta-Gehirnwellen auf. Mittels Neurofeedback wird versucht, die Gehirnfunktionen zu korrigieren. Zahlreiche Einzellfallstudien bestätigen die Wirksamkeit dieser Therapiemethode bei der AD/HS-Behandlung. Bisher wurde jedoch keine Studie veröffentlicht, in der die Wirksamkeit von Neurofeedback mit einer Placebogruppe verglichen wurde. Ziel der vorliegenden Studie war es, die Wirksamkeit eines Theta/Beta-Neurofeedbacks (NF) bei der Behandlung von AD/HS-Kindern zu überprüfen und mit einem EMG-Biofeedback (BF) als Placebobedingung zu vergleichen. Es wurden 35 ADHS-Kinder (6 -14 Jahre; 26 Jungen und 9 Mädchen) untersucht. Nach Standarddiagnostik und Vergabe der AD/HS-Diagnose durch einen unabhängigen Psychotherapeuten wurden die Kinder per Zufall zwei Gruppen (NF: n = 18 bzw. BF: n = 17) zugeteilt. Alle Kinder beider Gruppen erhielten ein 30 Sitzungen umfassendes Training mittels Theta/Beta-Neurofeedback bzw. EMG-Biofeedback. Unmittelbar vor und nach dem Training wurden Intelligenz- bzw. Aufmerksamkeitsleistungen untersucht und Einschätzungen des Verhaltens von Eltern und Lehrern erhoben. Im Anschluss an das Training erfolgte eine erneute diagnostische Einschätzung durch einen unabhängigen Psychotherapeuten. Die EEG-Daten in der NF-Gruppe zeigen eine Reduktion der Theta/Beta-Quotienten im Laufe der NF-Sitzungen. Die EMG-Daten zeigen für die EMG-Biofeedback-Bedingung gleichfalls eine Reduktion der EMG-Amplitude. Die Ergebnisse der zweifaktoriellen Varianzanalysen mit Messwiederholung auf einem Faktor zeigen für die angewendeten diagnostischen Verfahren die erwarteten signifikanten Interaktionen zwischen Messzeitpunkt und Gruppe. Die Ergebnisse des t-Tests zeigen signifikante Verbesserungen in der Aufmerksamkeitsleistung, dem Intelligenzniveau und im Verhalten der Kinder aus der NF-Gruppe im Vergleich zu den Resultaten des Prä-Tests. Die EMG-Biofeedbackgruppe zeigt mit Ausnahme einer Erhöhung des Arbeitstempos in den Paper-Pencil-Aufmerksamkeitstests (die im CPT nicht repliziert werden konnte) keine signifikanten Verbesserungen relativ zum Prä-Test. Nach dem Training erhielten 55,6 % (n = 10) der AD/HS-Kinder aus der Neurofeedbackgruppe und 23,5 % (n = 4) der Kinder aus der EMG-Biofeedbackgruppe keine AD/HS-Diagnose nach den Kriterien der ICD-10. Der Chi-Quadrat-Test zeigt jedoch lediglich einen tendenziell bedeutsamen Unterschied (p = .086). Insgesamt bestätigen die Ergebnisse die Wirksamkeit des Neurofeedbacks bei der Behandlung von ADHS-Kindern im Vergleich mit einer Placebogruppe. Weitere Studien in diesem Bereich sind notwendig, um die Wirksamkeit des Neurofeedbacktrainings im Vergleich zu einer Placebomethode bei der ADHS-Behandlung zu untersuchen. N2 - Neurofeedback (NF) has been introduced four decades ago as an alternative treatment for different disorders, one of these being Attention Deficit/Hyperactivity Disorder (AD/HD). As compared to a control group (non ADHD children), children diagnosed with ADHD show an increased frequency of Theta waves and a decreased frequency of Beta waves in their EEGs. A treatment consisting of NF-training attempts to correct these anomalies. There are numerous single case studies in this area but only a few controlled studies. Furthermore, there are no studies comparing the effect of NF in the treatment of ADHD with a placebo group. This study sets out to evaluate the effects of 30 (Theta/Beta) NF training sessions on ADHD symptoms and compare those with the effects of the placebo EMG-biofeedback (BF) training group. The subjects, consisting of 35 children both male (n = 26) and female (n = 9) between the ages of 6 and 14 diagnosed with ADHD by independent psychotherapists, were randomly assigned to either the treatment group (NF; n = 18) or the placebo group (BF; n = 17). In addition to the Theta/Beta quotient (in NF group) and EMG-Amplitude (in BF group) as seen during the sessions, pre and post measures of the subjects´ intelligence (Raven Test), paper-pencil attention test scores (bp/d2), Continuous Performance Task (CPT) as well as symptom ratings (MEF and FBB-HKS) from both teachers and parents were obtained. Finally, subjects were re-evaluated after treatment by independent psychotherapists. The results showed a significant decrease in the Theta/Beta quotient after the NF training and a significant decrease in the EMG-Amplitude after the BF-training. The results of an ANOVA with repeated measures showed significant differences between the treatment group (NF training) and the placebo (BF training) group in attention tests and symptom rating scores after treatment. Compared to the pre-test scores, subjects in the NF group showed significant improvements in attention scores, intelligence scores, and behaviour after the NF training sessions. The BF placebo group showed no significant improvements in any of the outcome variables except on the speed scale of the paper-pencil attention tests (this was incompatible with the results of CPT). Finally, 55.6% (n = 10) of the children in the NF training group were not diagnosed with ADHD (using ICD-10 criteria) at the time of the second evaluation. In the BF group, 23.5% (n = 4) were not diagnosed with ADHD by independent psychotherapists at the end of the BF training. The results indicate that NF training in comparing with a placebo method is an effective treatment method in the treatment of ADHD children. Further studies are necessary in comparing the effectiveness of NF training with more neutral placebo interventions in the treatment of children with ADHD.

Secondly, findings on neurological correlates of interpersonal synchrony (assessed with EEG, fMRI, fNIRS) are summarized in a narrative manner. In addition, the question is asked whether interpersonal synchrony can be achieved voluntarily on an individual level. It is concluded that there might be mechanisms which could give more insights into therapy success, but as of yet remain uninvestigated. Further, the framework of embodied cognition applies more to the current body of evidence than classical cognitivist views. Nevertheless, deeper research into interpersonal physical and neurological processes utilizing the framework of Embodied Cognition emerges as a possible route of investigation on the road to lower drop-out rates, improved and quality-controlled therapeutic interventions, thereby significantly reducing healthcare costs.
