BACKGROUND: The OpenGo seems promising to take gait analysis out of laboratory settings due to its capability of long-term measurements and mobility. However, the OpenGo's concurrent validity and reliability need to be assessed to determine if the instrument is suitable for validation in patient samples. METHODS: Twenty healthy volunteers participated. Center of pressure data were collected under eyes open and closed conditions with participants performing unilateral stance trials on the gold standard (AMTI OR6-7 force plate) while wearing the OpenGo...

We developed and evaluated properties of a new measure of variability in stride length and cadence, termed residual standard deviation (RSD). To calculate RSD, stride length and cadence are regressed against velocity to derive the best fit line from which the variability (SD) of the distance between the actual and predicted data points is calculated. We examined construct, concurrent, and discriminative validity of RSD using dual-task paradigm in 14 below-knee prosthesis users and 13 age- and education-matched controls...

The purpose of this paper is to develop an accelerometry system capable of performing gait event demarcation and calculation of temporal parameters using a single waist-mounted device. Particularly, a mobile phone positioned over the L2 vertebra is used to acquire trunk accelerations during walking. Signals from the acceleration magnitude and the vertical acceleration are smoothed through different filters. Cut-off points between filtered signals as a result of convolving with varying levels of Gaussian filters and other robust features against temporal variation and noise are used to identify peaks that correspond to gait events...

BACKGROUND: Demographic growth in conjunction with the rise of chronic diseases is increasing the pressure on health care systems in most OECD countries. Physical activity is known to be an essential factor in improving or maintaining good health. Walking is especially recommended, as it is an activity that can easily be performed by most people without constraints. Pedometers have been extensively used as an incentive to motivate people to become more active. However, a recognized problem with these devices is their diminishing accuracy associated with decreased walking speed...

The aim of this systematic review was to evaluate the impact of bilaterally symmetrical backpack systems borne on the posterior trunk on walking biomechanics, as backpacks represent the most prevalent methods of load carriage in the military and civilian population. A search of electronic databases was performed for studies that only investigated posteriorly borne backpack carriage during level grade walking (treadmill and over ground). Methodology of studies was assessed, and both meta-analysis and qualitative synthesis were completed...

AIMS: The surgical management of ankle arthritis with tibiotalar arthrodesis is known to alter gait, as compared with normal ankles. The purpose of this study was to assess post-operative gait function with gait before arthrodesis. PATIENTS AND METHODS: We prospectively studied 20 patients who underwent three-dimensional gait analysis before and after tibiotalar arthrodesis. Cadence, step length, walking velocity and total support time were assessed. Kinetic parameters, including the moment and power of the ankle in the sagittal plane and hip power were also recorded...

We analysed nine patients who had had a megaprosthesis implanted into the distal femur and knee joint for treatment of sarcomas. Data obtained from the leg operated on were compared with those from the contralateral side and healthy volunteers. Gait data, kinematics, ground reaction forces and the EMG from five muscles around the knee joint were analysed by means of a video-based analysis system recording data from reflection markers ; a Kistler-plate recorded the GRF and a ten channel surface EMG the muscle activity...

OBJECTIVE: Walking disorders are common in patients with multiple sclerosis (MS). Among these, walking fatigability is a common complaint of patients, but it needs to be better characterized. This work aims to compare the fatigability induced by a 2, and a 6- minute walk test (2MWT; 6MWT) and to investigate the factors associated with it. MATERIALS/PATIENTS AND METHODS: Twenty-seven MS patients (divided into subgroups according to disease severity [EDSS 3-4 and 4...

OBJECTIVE: Turning around while stepping in place can be produced voluntarily. One way of producing involuntary turning around while stepping-in-place eyes closed is by training subjects onto a rotating platform while stepping-in-place and maintaining a fixed body orientation in space. This task produces a post-effect called "podokinetic after-rotation" (PKAR). Such training has been suggested for Parkinsonian patients. We tested the hypothesis that voluntary stepping-in-place and turning around also produces a post-effect similar to the PKAR...

OBJECTIVE: Hereditary spastic paraplegia (HSP) designates a rare genetic disorder characterized by the existence of a pyramidal syndrome and/or paresis of the lower limbs, resulting in locomotor disorders. The objective of this study was to investigate the HSP patients walking characteristics during a comfortable walking speed, to determinate the most deleterious impairments and their evolutivity during a prolonged standardized walk. A second goal was to study the co-contraction of targeted muscles during these two walking conditions...

We aimed to determine the effect of aquatic cycling and different levels of immersion on respiratory responses in healthy and heart disease (HD) volunteers. Thirty-four age matched volunteers, 21 HD and 13 healthy controls (HC) took part in this study. The ventilatory pattern, phase 1VE and steady-state ventilatory responses to progressive exercise from 40 to peak rpm, were measured while participants exercised on a water stationary bike (WSB) at different levels of immersion. No effect of immersion was observed on steady-state respiratory responses in the HD group, but immersion reduced VE phase 1 by ∼79% at pedaling cadences of 40, 50 and 60rpm...

PURPOSE: To catalog the relationships between step-based accelerometer metrics indicative of physical activity volume (steps/day, adjusted to a pedometer scale), intensity (mean steps/min from the highest, not necessarily consecutive, minutes in a day; peak 30-min cadence) and sedentary behavior (percent time at zero cadence relative to wear time; %TZC) and cardiometabolic risk factors. METHODS: We analyzed data from 3388 20+ year-old participants in the 2005-2006 National Health and Nutrition Examination Survey with ≥1 valid day of accelerometer data and at least some data on weight, BMI, waist circumference, systolic and diastolic blood pressure, glucose, insulin, HDL-cholesterol, triglycerides, and/or glycohemoglobin...
