BACKGROUND Gait parameters such as gait speed (GS) are important indicators of functional capacity. Frailty Syndrome is closely related to GS and is also capable of predicting adverse outcomes. The cognitive demand of gait control is usually explored with dual-task (DT) methodology. OBJECTIVE To investigate the effect of DT and frailty on the spatio-temporal parameters of gait in older people...

The purpose of this study was to assess the concurrent validity and test-retest reliability of a sensor-based gait analysis system. Eleven healthy subjects and four Parkinson's disease (PD) patients were asked to complete gait tasks whilst wearing two inertial measurement units at their feet. The extracted spatio-temporal parameters of 1166 strides were compared to those extracted from a refere...

Aim. Recent evidence suggested that the use of treadmill training may improve gait parameters. Visual deprivation could engage alternative sensory strategies to control dynamic equilibrium and stabilize gait based on vestibulospinal reflexes (VSR). We aimed to investigate the efficacy of a blindfolded balance training (BBT) in the improvement of stride phase percentage reliable gait parameters ...

Gait analysis was performed on 20 patients with unilateral hip prosthesis (3, 6 and 12 months postoperatively) and 20 controls to investigate their gait characteristics and muscle activation patterns. One year after the intervention, patients still walked with a higher percentage of “atypical” cycles, a 2 prolonged heel contact, a shortened flat foot contact, a reduced hip dynamic range of moti...

BACKGROUND Performing gait analysis in a clinical setting can often be challenging due to time, cost and the availability of sophisticated three-dimensional (3D) gait analysis systems. This study has developed and tested a portable wireless gait assessment tool (wi-GAT) to address these challenges. AIM To investigate the concurrent validity of the wi-GAT in measuring spatio-temporal gait para...

A gait-recognition technique that recovers static body and stride parameters of subjects as they walk is presented. This approach is an example of an activity-specific biometric: a method of extracting identifying properties of an individual or of an individual’s behavior that is applicable only when a person is performing that specific action. To evaluate our parameters, we derive an expected ...

We share the results of a preliminary experiment where participants performed a simple task in a control immersive virtual environment (IVE) followed by a stressful IVE. Participants’ gaits were recorded with a motion capture system. We computed speed, stride length, and stride width for each participant and found that participants take significantly shorter strides in the stressful environment...

OBJECTIVES To evaluate the effects of gait training using a treadmill with and without visual biofeedback in patients in the late period after stroke, and to compare both training methods. DESIGN A randomized, controlled study. SUBJECTS Fifty people at least 6 months after stroke, randomly enrolled into groups with a rehabilitation programme of treadmill training with or without visual biof...

OBJECTIVE The aim of this study was to examine the relationships between lower limb muscular deficiencies and postural and gait capacities. DESIGN Observational study. SUBJECTS A total of 26 patients with Charcot-Marie-Tooth disease and 19 health-matched healthy subjects. METHODS Barefoot gait and postural control were analysed using a walking mat and a force platform, respectively. Muscu...

Gait analysis is a systematic collection of quantitative information on bodily movements during locomotion. Gait analysis has been employed clinically in stroke patients for their rehabilitation planning. In animal studies, gait analysis has been employed for the assessment of their locomotive disturbances in ischemic stroke, spinal cord injury and Parkinson's disease. The aims of the work repo...
