Hemophilia A Clinical Trial
Official title:
Evaluation of Viscoelastic Properties of Lower Extremity Muscles in Patients With Hemophilia
The aim of our study is to evaluate the viscoelastic properties of lower extremity muscles in patients with hemophilia A and hemophilia B secondarily to compare them with their healthy peers.
Hemophilia is a rare inherited coagulation disorder that develops as a result of factor VIII (hemophilia A) or factor IX (hemophilia B) deficiency, and is a chronic group of diseases that mainly manifests with intra-articular (hemarthrosis) and intramuscular (hematoma) bleeding, affecting quality of life. The presence of easy ecchymosis formation in early childhood, especially intra-articular and intramuscular spontaneous bleeding, interventions and a history of bleeding that lasted longer than expected after trauma should suggest hemophilia. The severity of bleeding findings is directly related to the degree of deficiency of hemophilia A and B. Hemarthroses due to bleeding in the joint (80%) and hematomas due to intramuscular bleeding (20%) cause joint degeneration and muscle atrophy. The joint in which hemarthrosis is most common is the knee joint, however, bleeding into the lower extremity muscles seriously affects the activities of daily living and lower extremity functionality. For this reason, the researchers aimed to evaluate the viscoelastic properties of lower extremity muscles in hemophilia patients and, secondarily, to compare them with their healthy peers. ;
