Development of an abnormal walking detection system for people with stroke hemiplegia

UMIN ID: UMIN000054407

Registered date:15/06/2024

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: Healthy people and stroke hemiplegia
• Date of first enrollment: 2024/06/10
• Target sample size: 10
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

VICON's three-dimensional motion analysis system was used for measurement. The measurement time is expected to take about 2 hours. In addition, in order to easily calculate GDI clinically, we plan to use "Open cap" developed by Stanford University (https://www.opencap.ai). By using this, you can easily measure the joint angle and walking speed in the clinical field without using a large-scale device, and it will be possible to calculate GDI. However, since the accuracy of the Open cap has not been verified, three-dimensional motion analysis and Open cap are measured at the same time, and the walking speed and joint angle are extracted respectively to verify the accuracy of the Open cap.
