Utilizing machine learning techniques in estimating ankle prosthesis power output using wearable IMU sensors
Ankle power output can be used to identify abnormalities and uneven weight distribution in gait. The acquring of the ankle power output usually involves using invasive motion capture systems along with force plates to capture the exerted power on the ground during stance phase. When clinicians are …
