Background: Reduced exercise capacity in patients with heart failure (HF) could be partially explained by skeletal muscle dysfunction. We compared function, structure, and metabolism among clinically stable outpatients HF preserved ejection fraction, reduced healthy controls (HC). Furthermore, the molecular, metabolic, clinical profile of endurance was described. Methods: Fifty-five participants were recruited prospectively at University Hospital Jena (17 18 20 HC). All underwent...

Zusammenfassung Für das vorherrschende Symptom Fatigue im Rahmen des Post-COVID-Syndroms (PCS) existieren weiterhin nur eingeschränkte Behandlungsstrategien. Hydrotherapeutische Verfahren zeigten bei anderen Ursachen der positive Effekte. Das primäre Ziel ist es erstmals objektivierbare Daten mittels HRV zur Wirksamkeit von Kniegüssen nach Kneipp auf die Fatique Post-COVID zu generieren. Personen mit relevanter Fatigue, gemessen Chalder Skala, wurden in Studie eingeschlossen. Die...

Walking disabilities negatively affect inclusion in society and quality of life increase the risk for secondary complications. It has been shown that external feedback applied by therapists and/or robotic training devices enables individuals with gait abnormalities to consciously normalize their pattern. However, little is known about effects a technically-assisted over ground therapy. The aim this study was assess whether automatic real-time provided shoe-mounted inertial-sensor-based...

Impaired tissue oxygenation is the key pathomechanism in development of organ dysfunction shock; mitochondrial impairment can aggravate condition. However, measuring directly and non-invasively still poses a clinical challenge. A novel device (COMET) allows assessment oxygen metabolism using Protoporphyrin IX Triplet State Lifetime Technique (PpIX-TSLT). Critically ill patients, especially sepsis, often exhibit oedema which may interfere with COMET measurement. Furthermore, patients'...

Abstract Treatment modalities of spinal pain patients are discussed diversely, and different multimodal therapy programs have been developed. Purpose the present study was to evaluate outcome effectiveness an inpatient interdisciplinary treatment program. This prospective multicentre clinical trial has performed with from orthopedic hospitals receiving a functional musculoskeletal pathway. Outcome measures were intensity back-specific function (Oswestry Disability Index) before (T1) after...

Incomplete spinal cord injury (iSCI) leads to motor and sensory deficits. Even in ambulatory persons with good function an impaired proprioception may result insecure gait. Limited internal afferent feedback (FB) can be compensated by provision of external FB therapists or technical systems. Progress computational power motion analysis systems allows for implementation instrumented real-time FB. The aim this study was test if individuals iSCI normalize their gait kinematics during more...

Background: Mitochondria are the key players in aerobic energy generation via oxidative phosphorylation. Consequently, mitochondrial function has implications on physical performance health and disease ranging from high sports to critical illness. The protoporphyrin IX-triplet state lifetime technique (PpIX-TSLT) allows vivo measurements of oxygen tension (mitoPO 2 ). Hitherto, few data exist relation metabolism ergospirometry-derived variables during performance. This study investigates...

Abstract Aims Both left atrial strain (LAS) and skeletal muscle endurance demonstrate a linear relationship to peak VO 2 . Less is known about the between central (cardiac) peripheral (muscle endurance) limitations of exercise capacity in patients with heart failure (HF). We investigated this using novel cardiac markers such as LAS emptying fraction (LAEF). Methods results analysed echocardiographic measurements, cardiopulmonary testing (CPET), isokinetic function 55 subjects HF controls [17...

Measurements of exercise‐induced metabolic changes, such as oxygen consumption, carbon dioxide exhalation or lactate concentration, are important indicators for assessing the current performance level athletes in training science. With exercise‐limiting processes occurring loaded muscles, 31 P‐MRS represents a particularly powerful modality to identify and analyze corresponding training‐induced alterations. Against this background, study aimed adaptations after an exhaustive exercise two...
