Although visual cues can improve gait in Parkinson's disease (PD), their underlying mechanism is poorly understood. Previous research suggests that cues contribute optical flow that is essential to elicit gait improvement. The present study manipulated how optic flow was provided, and how this might influence freezing of gait (FOG) in PD. Therefore, three groups; 15 PD FOG, 16 PD non-FOG, and 1...

OBJECTIVE To identify clinical and biomechanical parameters that influence swing-phase knee flexion and contribute to stiff-knee gait in individuals with spastic cerebral palsy (CP) and flexed-knee gait. DESIGN Retrospective analysis of clinical data and gait kinematics collected from 2010 to 2013. SETTING Motion and gait analysis laboratory at a children's hospital. PARTICIPANTS Individu...

We examined swimming behaviour, gait recruitment and post-exercise muscle glycogen, muscle lactate, plasma lactate and oxygen consumption in smallmouth bass (Micropterus dolomieu; 24-38 cm fork length) that voluntarily ascended a 25 m raceway against water velocities ranging from 40 to 120 cm s(-1). Physiological parameters were referenced to additional measurements made following exhaustive ex...

This is the first time that gait characteristics of broiler (meat) chickens have been compared with their progenitor, jungle fowl, and the first kinematic study to report a link between broiler gait parameters and defined lameness scores. A commercial motion-capturing system recorded three-dimensional temporospatial information during walking. The hypothesis was that the gait characteristics of...

BACKGROUND The recovery of gait ability is one of the primary goals for patients following total arthroplasty of lower-limb joints. The aim of this study was to objectively compare gait differences of patients after unilateral total hip arthroplasty (THA), total knee arthroplasty (TKA) and total ankle arthroplasty (TAA) with a group of healthy controls. METHODS A total of 26 TAA, 26 TKA and 2...

BACKGROUND Evidence suggests that textured insoles can alter gait and standing balance by way of enhanced plantar tactile stimulation. However, to date, this has not been explored in older people at risk of falling. This study investigated the immediate effect of wearing textured insoles on gait and double-limb standing balance in older fallers. METHODS Thirty older adults >65 years (21 women...

OBJECTIVES To investigate the effects of rhythmic auditory stimulation (RAS) on gait patterns in comparison with changes after neurodevelopmental treatment (NDT/Bobath) in adults with cerebral palsy. DESIGN A repeated-measures analysis between the pretreatment and posttreatment tests and a comparison study between groups. SETTING Human gait analysis laboratory. SUBJECTS Twenty-eight cereb...

Microsoft Kinect is a motion sensing device that allows us to conveniently capture human body motions and extract skeletal data. For biometric from human gait, Kinect lets us extract more kind and more complicated gait features which help improve identification accuracy. This paper proposes biometric from human gait technique from view independent gait analysis based on the Kinect’s motion trac...

Postural control during dynamic activities such as initiating gait and locomotion, requires the integration of multiple sensory and motor pathways so that the central nervous system can coordinate the anticipatory/postural and intentional /movement components of the task. Persons with Parkinson’s disease (PD) exhibit a marked deficit in maintaining equilibrium during transitions between states ...
