简要总结
Knee osteoarthritis is a common cause of disability, affecting more than 650 million people aged 40 and over worldwide in 2020. To relieve pain and improve mobility, some patients use knee orthoses . However, the effectiveness of these devices is not universally agreed upon, and users report widely varying levels of satisfaction.
This study aims to understand how the body responds to these orthoses from a biomechanical perspective, and in particular to quantify the interactions with soft tissues (skin, adipose tissue and muscles). To better understand this interaction, the authors propose to characterize soft tissue behavior on an individual basis using an indentation technique. In practice, this involves pressing on the soft tissues with an ultrasound probe to measure their stiffness at the interface between the leg and the orthosis.
