NCT03843684

Brief Summary

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.

Conditions

Outcome Measures

Primary Outcomes (3)

  • Knee adduction moment during level walking and stair negotiation

    Surrogate marker of medial knee loading. Using motion capture system data to calculate the knee adduction moment via inverse dynamics method.

    10 minutes

  • Medial knee joint contact force during level walking and stair negotiation

    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.

    10 minutes

  • Muscle co-activation ratio during level walking and stair negotiation

    Level of muscle co-activation measured by electromyography (EMG).

    10 minutes

Secondary Outcomes (3)

  • 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
