TY - JOUR A1 - Frank, Ulrike A1 - Frank, Katrin T1 - COVID-19 BT - neue Herausforderungen in der Dysphagie- und Atemtherapie BT - new challenges in dysphagia and respiratory therapy JF - Der Nervenarzt : Organ der Deutschen Gesellschaft für Psychiatrie, Psychotherapie und Nervenheilkunde ; Mitteilungsblatt der Deutschen Gesellschaft für Neurologie N2 - Eine COVID-19-Erkrankung kann zu schweren Krankheitsverläufen mit multiplen Organbeteiligungen und respiratorischen und neurologischen Funktionseinschränkungen führen. Schluckstörungen (Dysphagien) können in dieser Patientengruppe durch primäre Schädigungen des zentralen und peripheren neuronalen Netzwerkes der Schluckfunktion entstehen, aber auch bedingt durch die häufig längere intensivmedizinische Behandlung und Beatmung. Erste klinische Befunde zeigen persistierende Dysphagien im Rahmen des Post-COVID-Syndroms („Long-COVID“), sodass die Patienten auch längerfristige Maßnahmen zur Rehabilitation einer sicheren und suffizienten oralen Nahrungsaufnahme benötigen. Daher sollte in die Behandlung von COVID-19-Patienten ein strukturiertes erkrankungsspezifisches Monitoring in Bezug auf Dysphagiesymptome integriert werden, und atemtherapeutische Maßnahmen zur Regulation von Husteneffektivität und Atem-Schluck-Koordination sollten auch bei diesen Patienten essenzieller Bestandteil des Dysphagiemanagements sein. Herausforderungen ergeben sich dabei einerseits durch die erforderlichen Anpassungen etablierter Behandlungsstandards an den Infektionsschutz. Zudem müssen Auswahl und Durchführungsintensität therapeutischer Maßnahmen an die Kapazitäten und die spezifische Pathophysiologie der COVID-19- und Long-COVID-Patienten angepasst werden, um weitere funktionelle Verschlechterungen zu vermindern. N2 - Coronavirus disease 2019 (COVID-19) can lead to severe disease courses with multiple organ involvement, respiratory and neurological functional impairments. Swallowing disorders (dysphagia) in this patient group can result from primary damage to the central and peripheral neuronal swallowing network but also from the frequently prolonged intensive care treatment and mechanical ventilation. Clinical observations indicate persistence of dysphagia in post-acute COVID-19 syndrome (long COVID), so that these patients probably also need long-term interventions for rehabilitation of safe and sufficient oral feeding. Therefore, structured disease-specific monitoring of dysphagia symptoms should be integrated into the treatment of COVID-19 patients and respiratory therapy should be an essential part of dysphagia management to re-establish cough effectiveness and breathing-swallowing coordination. Challenges arise from necessary adjustments to established treatment standards to prevent infections. Furthermore, the selection and intensity of therapeutic measures have to be adapted to the capacities and the specific pathophysiology of COVID-19 and long COVID patients to prevent further functional deterioration.

Methods: Twenty-four professional basketball players from the first Tunisian (Tunisia) division participated in this study. The players were dichotomized by sex (males [GM = 12]; females [GF = 12]). Both groups completed a 4 weeks SSGs training program with 3 sessions per week. Psychometric (e.g., quality of sleep, fatigue, stress, and delayed onset of muscle soreness [DOMS]) and physiological parameters (e.g., heart rate frequency, blood lactate) were measured during the first week (baseline) and at the end of RIF (post-test). Results: Post hoc tests showed a significant increase in stress levels in both groups (GM [− 81.11%; p < 0.001, d = 0.33, small]; GF [− 36,53%; p = 0.001, d = 0.25, small]). Concerning physiological parameters, ANCOVA revealed significantly lower heart rates in favor of GM at post-test (1.70%, d = 0.38, small, p = 0.002). Conclusions: Our results showed that SSGs training at the end of the RIF negatively impacted psychometric parameters of male and female basketball players. It can be concluded that there are sex-mediated effects of training during RIF in basketball players, and this should be considered by researchers and practitioners when programing training during RIF.

T1 - Electromyographic adjustments during continuous and intermittent incremental fatiguing cycling JF - Psychotherapeut N2 - We studied the sensitivity of electromyographic (EMG) variables to load and muscle fatigue during continuous and intermittent incremental cycling. Fifteen men attended three laboratory sessions. Visit 1: lactate threshold, peak power output, and VO2max. Visits 2 and 3: Continuous (more fatiguing) and intermittent (less fatiguing) incremental cycling protocols [20%, 40%, 60%, 80% and 100% of peak power output (PPO)]. During both protocols, multichannel EMG signals were recorded from vastus lateralis: muscle fiber conduction velocity (MFCV), instantaneous mean frequency (iMNF), and absolute and normalized root mean square (RMS) were analyzed. MFCV differed between protocols (P<0.001), and only increased consistently with power output during intermittent cycling. RMS parameters were similar between protocols, and increased linearly with power output. However, only normalized RMS was higher during the more fatiguing 100% PPO stage of the continuous protocol [continuous-intermittent mean difference (95% CI): 45.1 (8.5% to 81.7%)]. On the contrary, iMNF was insensitive to load changes and muscle fatigue (P=0.14). Despite similar power outputs, continuous and intermittent cycling influenced MFCV and normalized RMS differently. Only normalized RMS was sensitive to both increases in power output (in both protocols) and muscle fatigue, and thus is the most suitable EMG parameter to monitor changes in muscle activation during cycling.
