This is a study in 3 phases that will assess the feasibility and utility of handheld home ultrasound (HHUS) in a patient's home to assess whether a painful episode in the elbow, knee or ankle is a bleed or not.
This is a study in 3 phases that will assess the feasibility and utility of handheld home ultrasound (HHUS) in a patient's home to assess whether a painful episode in the elbow, knee or ankle is a bleed or not.
Phase 1 will assess whether 10 subjects with severe hemophilia A can be trained to use HHUS in clinic to identify basic joint structures of the elbow, knee and ankle. It will then assess whether these subjects can identify these structures at home and transmit the images life via tele-ultrasound.
Phase 2 will assess whether the determination of "bleed" vs. "non-bleed" made at home via HHUS can be confirmed/validated with a standard high resolution ultrasound machine in clinic.
Phase 3 will then utilize HHUS during the EmiMSKUS study over 3 years to more objectively identify patient reported bleeding during the study.

| handheld ultrasound: Philips Lumify integrated tele-ultrasound powered by Reacts collaborative platform | Device | Patients receive training by the physical therapist to operate a handheld ultrasound (HHUS) including proper probe placement. Subjects will be tested on their knowledge at the HTC to demonstrate proficiency, and will then repeat the testing at home via tele-ultrasound. |
| Measure | Description | Time Frame |
|---|---|---|
| Outcome 1.1: Participant understanding of basic ultrasound transducer concepts and ability to perform basic positioning maneuvers. | Number of participating subjects who understand basic ultrasound transducer concepts and can perform basic positioning maneuvers based on post-training test. | 3 months |
| Outcome 1.2: Participating subjects are able to perform basic transducer positions and identify basic structures of the elbow, knee and ankle. | Number of participating subjects who are able to perform basic transducer positions and identify basic structures of the elbow, knee and ankle based on post-training test. | 3 months |
| Outcome 1.3: Participating subjects can perform what they learned during their training at the HTC in outcome 1.1 and outcome 1.2 at home and transmit images to the HTC. | Number of participating subjects who can perform what they learned during their training at the HTC in outcome 1.1 and outcome 1.2 at home and transmit images to the HTC on post-training test. | 3 months |
| Outcome 2.1: Subjects will be able to attain and transmit images of their joint spaces to the HTC via telemedicine utilizing the HHUS technology they learned in phase 1 and React App. | Number of subjects who will be able to attain and transmit images of their joint spaces to the HTC via telemedicine utilizing the HHUS technology they learned in phase 1 and React App. | 6 months |
| Outcome 2.2: Accuracy of the assignment of "bleed" vs. "non-bleed" will be determined on the stationary GE LS8 Logiq Pro in the HTC. | Percentage accuracy of the assignment of "bleed" vs. "non-bleed" will be determined on the stationary GE LS8 Logiq Pro in the HTC. | 6 months |
