Gait

How many strides are needed for reliable markerless gait analysis?

Comparison of Theia3D and the conventional gait model in typically developing children and adults in a clinical gait laboratory

Comparison of Marker- and Markerless-Derived Lower Body Three-Dimensional Gait Kinematics in Typically Developing Children

Background: Marker-based motion capture is the current gold standard for three-dimensional (3D) gait analysis. This is a highly technical analysis that is time-consuming, and marker application can trigger anxiety in children. One potential solution …

The inter-trial and inter-session reliability of Theia3D-derived markerless gait analysis in tight versus loose clothing

Background Gait analysis is traditionally conducted using marker-based methods yet markerless motion capture is emerging as an alternative. Initial studies have begun to evaluate the reliability of markerless motion capture yet …

Identifying joint-specific gait mechanisms causing impaired gait in alkaptonuria patients

Alkaptonuria is a rare genetic disease that leads to structural joint damage and impaired movement function. Previous research indicates that alkaptonuria affects gait, however the detailed mechanisms are unknown. Research question: What are the …

A kinematic comparison of gait with a backpack versus a trolley for load carriage in children

The use of a school trolley is reaching and even surpassing the use of backpacks in many countries, although a recommended load has not been studied. To accomplish this, 3D gait kinematics of the lower limbs and thorax were analysed in 49 students …

Vector-field statistics for the analysis of time varying clinical gait data

Background: In clinical settings, the time varying analysis of gait data relies heavily on the experience of the individual(s) assessing these biological signals. Though three dimensional kinematics are recognised as time varying waveforms (1D), …

Age-Related Deviation of Gait from Normality in Alkaptonuria

Alkaptonuria is a rare metabolic disease leading to systemic changes including early and severe arthropathy which affects mobility. For unknown reasons, the onset of degenerative changes is delayed to around 30 years of age when both objective and …

Vector field statistics for objective center-of-pressure trajectory analysis during gait, with evidence of scalar sensitivity to small coordinate system rotations

Center of pressure (COP) trajectories summarize the complex mechanical interaction between the foot and a contacted surface. Each trajectory itself is also complex, comprising hundreds of instantaneous vectors over the duration of stance phase. To …

Manipulation of visual biofeedback during gait with a time delayed adaptive Virtual Mirror Box

Background: A mirror placed in the mid-sagittal plane of the body has been used to reduce phantom limb pain and improve movement function in medical conditions characterised by asymmetrical movement control. The mirrored illusion of unimpaired limb …
