  Recruiting University Hospital, Bonn · Bonn, North Rhine-Westphalia · NCT07299565

• Blood Flow Restriction Training for older adults in acute rehabilitation

  This trial tests whether blood flow restriction training on a stationary bike can help improve muscle mass and general health in people over 65 during two weeks of acute geriatric rehabilitation after hip-related injury.

  Recruiting University Hospital, Bonn · Cologne, North Rhine-Westphalia · NCT07291765

• Tracking PXE-related changes at the back of the eye over time

  This study will see if repeated high-resolution eye imaging can track changes in Bruch's membrane, choriocapillaris blood flow, and retinal atrophy in people with PXE.

  Recruiting University Hospital, Bonn · Bonn, North Rhine-Westphalia · NCT07048106

• Strength training with blood-flow restriction after ACL reconstruction

  This trial will test whether adding blood flow restriction to light strength training helps people recovering from ACL reconstruction regain muscle, strength, and knee function during outpatient rehabilitation.

  Recruiting University Hospital, Bonn · Bonn, North Rhine-Westphalia · NCT07043569

• Strength training with blood flow restriction after hip replacement

  This trial tests whether adding supervised strength training with blood flow restriction to standard outpatient rehabilitation helps people who had a recent total hip replacement regain muscle strength and support muscle regeneration.

  Recruiting University Hospital, Bonn · Bonn, North Rhine-Westphalia · NCT07043127

• Anterior (front) temporal lobe removal for temporal glioblastoma

  This will see if removing the front part of the temporal lobe (anterior temporal lobectomy) helps people with newly diagnosed temporal-lobe glioblastoma live longer than standard complete tumor removal (gross-total resection).

  Recruiting Phase 3 University Hospital, Bonn · Bonn, North Rhine-Westphalia · NCT07021339

• Comparing two types of tourniquets during knee surgery
