Sonography and Haemophilia

Self-conducted Sonographic Monitoring of the Target Joints in Patients With Severe Haemophilia

The aim of this study is to evaluate the possibility of establishing a patient-based ultrasound monitoring of the knee (representing a target joint accessible with any hand) with a handheld device:

The following questions will be answered:

1. What is necessary for the organisational implementation of a patient-based ultrasound monitoring in patients with haemophilia?
2. Is it possible to train patients with haemophilia to perform sonography of their target joints?
3. Does a patient-based ultrasound monitoring with a handheld device work in a home setting?
4. What is the quality of the patient's self-acquired ultrasound images?
5. Will the test persons be able to distinguish normal findings from (any) pathologic findings?

• No professional medical background
• Submitted written consent to participate in the study and to use their study related pseudonymized data
