Published: November 2021

Background And Objective: The Vicon motion capture system is a popular tool for biomechanics, gait analysis, and robotics. The ASCII files produced are large and complex, making them difficult to read and analyze.

Methods: This paper presents two packages, the Vicon Toolkit Package and the Gait Analysis Toolkit Package. They use an open-source framework for ingesting, parsing, and analyzing Vicon mocap data and performing gait analysis. The package that handles the Vicon analysis is separated from the Gait Analysis package to allow for abstraction and expansion, and is not specific only to the Vicon system.

Results: Our Vicon Toolkit provides tools to work directly with the marker data and other Vicon Nexus system outputs. The Gait Toolkit provides tools for performing gait analysis, EMG filtering, and learning trajectories. The packages are built upon a core library, GaitCore, that provides unified objects to perform operations and store data.

Conclusion: This paper will show how to use the packages' tools and the expected outputs. All the tools are open-source and written in Python3.x for ease of use and access to other powerful libraries.

Background: Age-related decline in goal-directed behavior could be risky for older adults to maintain daily activities. Our previous studies have shown that long-term Tai Chi (TC) practice could improve motor performance and postural control during goal-directed tasks. However, there was a paucity of studies examining TC's effects on online control of goal-directed action.

Background: Although stroke patients gain an advantage in gait due to the knee hyperextension that occurs during the stance phase, this situation disrupts the biomechanical structure of the knee and increases the risk of injury to the capsular and ligamentous structures. The aim of this study was to examine the effects of rigid taping on hyperextension control and pelvic kinematics in stroke patients with knee hyperextension during the stance phase of gait.

Research Question: Does rigid taping have an effect on hyperextension control and pelvic kinematics in stroke patients with knee hyperextension?

Methods: Thirty stroke patients aged between 40 and 70 were included in this pre-postintervention study.

Department of Physical Therapy, Universidade Federal de Ciências da Saúde de Porto Alegre, Porto Alegre, Rio Grande do Sul, Brazil.

Objective(s): To determine (1) the quality of systematic reviews about dance-based intervention in individuals with Parkinson's disease (PD) and (2) standard evidence for dance-based intervention efficacy based on the categories of The International Classification of Functioning, Disability, and Health (ICF) from the World Health Organization's (WHO).

Methods: The data source included MEDLINE, PUBMED, Embase, Scopus, CENTRAL (Cochrane Library), CINAHL, PEDro, SPORTDiscus, APA PsycNet (APA PsycINFO), LILACS, SciELO, and AMED. Pairs of independent reviewers screened titles, abstracts, and full texts of eligible studies by using the software Covidence.

Background: Reduced step length is a hallmark of gait disturbance in people with Parkinson's disease (PD). Although treadmill training is effective for improving step length, the associated neural mechanisms have not been fully investigated. Moreover, exploring the baseline neurophysiological predictors for step length improvement after training could facilitate personalized gait rehabilitation for PD.
