The effect of foot deformities on the interplay of forces within the foot: An analysis of multi-segment foot joint moments in cerebral palsy Open
The direction of the differences found in cavovarus, equinovarus and planovalgus feet indicates that the internal joint moments are generally opposite to the malalignment of the foot. This indicates that external joint moments, which are c…

Foot and Ankle Biomechanics During Gait of Patients with an Osteochondral Lesion of the Talus Open
Category: Ankle; Basic Sciences/Biologics Introduction/Purpose: An osteochondral lesion of the talus (OLT) is a defect of talar cartilage and subchondral bone, primarily linked to a history of ankle trauma. Mechanical overload is considere…

Using dynamic ultrasound to assess Achilles tendon mechanics during running: The effect on running pattern and muscle–tendon junction tracking Open
Achilles tendon strain can be quantified using dynamic ultrasound, but its use in running is limited. Minimal effects on running pattern and acceptable test-retest reliability of muscle-tendon junction (MTJ) tracking are prerequisites for …

Multi-segment foot kinematics during gait in children with spastic cerebral palsy Open
Foot deformities (e.g. planovalgus and cavovarus) are very common in children with spastic cerebral palsy (CP), with the midfoot often being involved. Dynamic foot function can be assessed with 3D gait analysis including a multi-segment fo…

Skin marker-based versus bone morphology-based coordinate systems of the hindfoot and forefoot Open
Segment coordinate systems (CSs) of marker-based multi-segment foot models are used to measure foot kinematics, however their relationship to the underlying bony anatomy is barely studied. The aim of this study was to compare marker-based …

The Amsterdam Foot Model: a clinically informed multi‐segment foot model developed to minimize measurement errors in foot kinematics Open
Background Foot and ankle joint kinematics are measured during clinical gait analyses with marker‐based multi‐segment foot models. To improve on existing models, measurement errors due to soft tissue artifacts (STAs) and marker misplacemen…

Knee Angle and Stride Length in Association with Ball Speed in Youth Baseball Pitchers Open
The purpose of this study was to determine whether stride length and knee angle of the leading leg at foot contact, at the instant of maximal external rotation of the shoulder, and at ball release are associated with ball speed in elite yo…
