Vibration Training Approach in Liver Cirrhosis

Inclusion Criteria: * Patients with confirmed or newly diagnosed compensated liver cirrhosis suffering from sarcopenia (combined decrease in muscle mass and muscle strength) * The liver cirrhosis is in a compensated stage. * The following etiologies of chronic liver disease are present: chronic hepatitis B infection, chronic hepatitis C infection, alcoholic liver disease, autoimmune hepatitis, cholestatic liver disease (PBC, PSC), or other chronic hepatopathy. * Alcohol abstinence of at least 3 months in cases of alcohol-related liver disease. * Routine cancer screening for the presence of a liver tumor (HCC surveillance) is routinely performed using MRI or CT scans, as ultrasound assessment is severely limited. * Permission from the treating physician to engage in physical activity. * Signed informed consent form. Exclusion Criteria: * Non-compliance with inclusion criteria * Patients with recent hospitalizations (within the last 3 months) due to gastrointestinal bleeding, hepatic encephalopathy, or spontaneous bacterial peritonitis * Presence of inadequately treated portal hypertension * Known chronic liver disease not described in the above groups * Alcohol consumption \>20 g per day * Excessive alcohol consumption during the study period leads to exclusion from the study * Substance abuse * Taking medications known to affect muscle mass or strength (e.g., Amiodarone, Chloroquine, Macrolides) * Taking medications known to cause movement disorders (e.g., Reserpine, Lithium, Cyclosporine A, Dopamine agonists) * Patients with unstable cardiovascular diseases: e.g., unstable angina pectoris, uncontrolled hypertension (≥ 160/100 mmHg), uncontrolled diabetes (blood sugar \> 250 mg/dl), history of myocardial infarction or stroke * Patients with musculoskeletal deformities, symptomatic rheumatoid or osteoarthritis * Patients with untreated or newly diagnosed active malignant tumors in history * Patients with neuromuscular or neurodegenerative diseases * Patients with untreated hernias * Patients with symptomatic, known untreated aortic aneurysm, with recent hospitalizations (within the last 6 months) * Patients with fractures within the last 12 months * Participation in moderate-intensity training programs for more than 2 hours per week * Patients who have received chemotherapy at the time of the study or in the past 3 months * Other underlying conditions that contraindicate vibration training and/or functional performance tests * Circumstances preventing the individual from assessing the nature, scope, and possible consequences of the clinical trial * Signs indicating that the subject is likely not to adhere to the study protocol (e.g., lack of cooperation) a. Definition of hepatic decompensation * Occurrence of symptomatic ascites, hepatic encephalopathy, portal hypertensive bleeding (e.g., esophageal variceal bleeding), infection
