研究概览
简要总结
The purposes of this study are: (1) to determine the kinematics, kinetics, and muscle co-activation ratio of level walking and stair negotiation under three different conditions (shoes only, shoes embedded 3D printed insoles, and shoes embedded 5-degree lateral wedges), (2) to build a detailed patient-specific knee model via MR images and musculoskeletal model, then, evaluate the compressive forces acting on the medial aspect of the knee during level walking and stair negotiation.
详细描述
This study is a cross-sectional study with patients serving as their own control. The investigators will recruit 20 patients with knee osteoarthritis. Using motion capture system, force plates, wireless EMG to capture the motion data of patients during walking and stair negotiation in each condition.

结局指标
主要结局
Knee adduction moment during level walking and stair negotiation
时间窗: 10 minutes
Surrogate marker of medial knee loading. Using motion capture system data to calculate the knee adduction moment via inverse dynamics method.
Muscle co-activation ratio during level walking and stair negotiation
时间窗: 10 minutes
Level of muscle co-activation measured by electromyography (EMG).
Medial knee joint contact force during level walking and stair negotiation
时间窗: 10 minutes
Calculate the medial knee force to identify the change in medial knee loading by musculoskeletal model. The musculoskeletal model is driven by motion capture system data.
次要结局
- Knee flexion moment during level walking and stair negotiation(10 minutes)
- Path of center of pressure during level walking and stair negotiation(10 minutes)
- Lower limbs joint angles during level walking and stair negotiation(10 minutes)
