- Primary Outcome Measures
Name Time Method <p>Main outcome measures are changes in oxygenated hemoglobine concentrations<br /><br>(O2Hb), deoxygenated hemoglobine concentrations (HHb), total hemoglobine (THb)<br /><br>and tissue saturation index (TSI). Those parameters will be determined in two<br /><br>protocols, with protocol 1 simulating prolonged sitting and protocol 2<br /><br>simulating descending stairs. Differences in changes between healthy subjects<br /><br>and patients with PFP will be investigated.</p><br>
