The Effect of Spinal Mobilization on Respiratory Parameters in Parkinson's Disease Patients

Parkinson's patients suffer from respiratory distress for different reasons. It is thought that physiotherapy methods that have an indirect effect on the diaphragm can improve respiratory functions. The aim of this study is to investigate the effects of spinal mobilization and diaphragmatic breathing techniques on respiratory function.

Thoracic Mobilization for Restrictive Lung Disease

This study aims to investigate the immediate effects of thoracic mobilization techniques on cough capacity, dyspnea, and pulmonary function in patients with restrictive lung disease. The intervention will be applied in a single session, and outcomes will be measured before and after the intervention to evaluate short-term physiological changes.

From Inflammation to Remodelling Towards Personalized Diagnosis in Post-acute Sequelae of COVID-19

Rationale: The diagnosis and pathogenesis of long COVID remains unknown. We have previously shown that \[68Ga\]FAPI Positron Emission Tomography-Computed Tomography (PET/CT) imaging shows potential for diagnosis and molecular understanding of this syndrome. We have previously shown that fibroblast activation protein (FAP) can be imaged in the lung, muscle and nasopharynx of long COVID patients (with dyspnea and fatigue). However, these preliminary data are derived from a selective group of patients with long COVID after critical COVID-19. We aim to explore the generalizability of these findings in patients with long COVID with dyspnea and fatigue, irrespective of the severity of their acute SARS-CoV-2 infection. Primary objective: To assess if pulmonary fibroblast activity, measured by \[68Ga\]FAPI-46 PET/CT, is higher in patients with current long COVID dyspnea and fatigue compared to patients with resolved complaints. Study design: This is a ZonMw funded single centre prospective observational cohort study of long COVID-19 patients with dyspnea and fatigue. Study population: We will recruit 60 adult long COVID patients (aged \>20 years) of which 30 have complaints of dyspnea and fatigue and compare them to 30 patients with resolved complaints and healthy controls. Main study parameters/endpoints: The primary endpoint is FAP expression in the lung measured by \[68Ga\]FAPI-46 PET/CT. Secondary endpoints are the expression of FAP in other tissues (muscle) and the relation between FAP and inflammation and remodelling biomarkers in various biological samples (e.g. serum/nasal epithelium). Study procedures: In a single visit day the following data and samples will be collected: questionnaires, a lung function test, 6-minute walking test, blood samples, nose swabs, \[68Ga\]FAPI PET/CT scan and HRCT scan. When increased \[68Ga\]FAPI uptake is measured in the muscles a muscle biopsy will be performed as well.
