The rising importance of movement analysis led to the development of more complex
biomechanical models to describe in detail the human motion patterns. The models scaled …

Foot and ankle joints are complicated anatomical structures that combine the tibiotalar and
subtalar joints. They play an extremely important role in walking, running, jumping and other …

Soft tissue movement between reflective skin markers and underlying bone induces errors in
gait analysis. These errors are known as soft tissue artifact (STA). Prior studies have not …

Two-dimensional video analysis is commonly used to assess kinematics when three-
dimensional motion capture is unavailable. However, videos are often assessed using …

Hip joint center (HJC) measurement error can adversely affect predictions from
biomechanical models. Soft tissue artifact (STA) may exacerbate HJC errors during dynamic …

Background Many two-dimensional (2-D) radiographic views are used to help diagnose cam
femoroacetabular impingement (FAI), but there is little consensus as to which view or …

Background: Tibiotalar arthrodesis is a common treatment for end-stage tibiotalar
osteoarthritis, and is associated with a long-term risk of concomitant subtalar osteoarthritis. It …

Rigid body musculoskeletal models have been applied to study kinematics, moments,
muscle forces, and joint reaction forces in the hip. Most often, models are driven with …

Measurements of joint kinematics are essential to understand the pathomechanics of ankle
disease and the effects of treatment. Traditional motion capture techniques do not provide …

Background Interpretation of shoulder motion across studies has been complicated due to
the use of numerous scapular coordinate systems in the literature. Currently, there are no …
