The aim of this study was to compare the seven following commercially available activity monitors in terms step count detection accuracy: Movemonitor (Mc Roberts), Up (Jawbone), One (Fitbit), ActivPAL (PAL Technologies Ltd.), Nike+ Fuelband (Nike Inc.), Tractivity (Kineteks Corp.) and Sensewear Armband Mini (Bodymedia). Sixteen healthy adults consented take part study. experimental protocol included walking along an indoor straight walkway, descending ascending 24 steps, free outdoor...
Objectives: Recognising human activity is very useful for an investigator about a patient's behaviour and can aid in prescribing future recommendations.The use of body worn accelerometers has been demonstrated to be accurate measure activity, however research looking at the multiple free living environment recognise wide range activities not evident.This study aimed successfully subcategory types through environment.Method: Ten participants (Age = 23.1 ± 1.7 years, height =171.0 4.7 cm, mass...
This paper presents a new approach to gait analysis and parameter estimation from single miniaturized ear-worn sensor embedded with triaxial accelerometer. Singular spectrum combined the longest common subsequence algorithm has been used as basis for estimation. It incorporates information all axes of accelerometer estimate parameters including swing, stance, stride times. Rather than only using local features raw signals, periodicity signals is also taken into account. The hypotheses tested...
Objective: To compare the gait of amputees wearing conventionally damped pneumatic swing-phase control knees and microchip-controlled Intelligent Prostheses. Design: Crossover trial. Setting: An amputee rehabilitation centre in a teaching hospital. Participants: Ten established unilateral transfemoral prosthetic users were asked to participate trial; all agreed. Interventions: The assessed then with Prosthesis. Main outcome measures: Oxygen consumption while walking at different speeds on...
Attention deficit and hyperactivity disorder (ADHD) is a neurodevelopmental disorder, which characterized by inattention, impulsive behaviors. In particular, children have difficulty keeping still exhibiting increased fine gross motor activity. This paper focuses on analyzing the data obtained from two tri-axial accelerometers (one wrist of dominant arm other ankle leg) worn during school hours group 22 (11 with ADHD 11 paired controls). Five diagnosed were not medication study. The...
Objective: To compare the cognitive demand of walking when using a conventional prosthesis with that microprocessor-controlled prosthesis. Design: Ten unilateral transfemoral amputees wearing pneumatic swing phase control (conventional prosthesis) prostheses walked on treadmill which enforced pattern constantly varying speeds. The subjects simultaneously performed simple or complex distracting task. Following period accustomization, same test microprocessor damping (the Intelligent...
Attention deficit and hyperactivity disorder (ADHD) is a neurodevelopmental condition that affects, among other things, the movement patterns of children suffering it. Inattention, impulsive behaviors, major symptoms characterizing ADHD, result not only in differences activity levels but also themselves. This paper proposes trains Recurrent Neural Network (RNN) to characterize moment for normally developing uses trained RNN order assess from with ADHD. Each child monitored 24 consecutive...
Our aim was to validate a sacral-mounted inertial measurement unit (IMU) for reconstructing running kinematics and comparing movement patterns within between runners. IMU data were processed using Kalman complementary filters separately. RMSE Bland-Altman analysis assessed the validity of each filtering method against motion capture system. Running from 24 recreational runners analyzed Fourier transform coefficients, PCA, k-means clustering. High agreement found Kalman-filtered in frontal,...
It is proposed that active contraction of muscles might be artificially replaced by a spring brake orthosis (SBO) to provide near-natural knee and hip swing phase trajectories for gait in spinal cord injured subjects. The SBO new restoration system which stored elastic energy potential limb segments are utilized aid gait. also shown flexion can produced without the need withdrawal reflex, flexor stimulus or any mechanical actuator at hip. A angle 21 degrees was achieved nonimpaired subject...
Real-time monitoring and feedback of tibial acceleration using wireless skin mounted sensors may reduce the risk stress fractures in runners. The purpose this study was to assess agreement between a accelerometer gold standard reference accelerometer, both mounted, measuring peak axial when treadmill running at range speeds. A research grade attached tibia. Peak positive accelerations 13 participants were compared 2.5, 3.5 4.5 m s− 1. Intraclass correlation coefficients demonstrated good...
To appraise the application of accepted good practice guidance on public involvement in assistive technology research and to identify its impact team, public, device trial design.Critical reflection within-project evaluation were undertaken a case study development functional electrical stimulation device. Individual group interviews with lay members 10 strong user advisory also team members.Public was seen positively by members, who reported positive designs. The identified confidence,...
Abstract: Discomfort experienced during surface functional electrical stimulation (FES) is thought to be partly a result of localized high current density in the skin underneath stimulating electrode. This article describes finite element (FE) model predict distribution region electrode and its application identification properties that may act reduce sensation. The FE results show peak was located an area immediately under stratum corneum, adjacent sweat duct. A simulation FES via...
Use of anthropometric data to infer sporting performance is increasing in popularity, particularly within elite sport programmes. Measurement typically follows standards set by the International Society for Advancement Kinanthropometry (ISAK). However, such techniques are time consuming, which reduces their practicality. Schranz et al. recently suggested 3D body scanners could replace current measurement techniques; however, systems costly. Recent interest natural user interaction has led a...
Many biomechanical analyses rely on the availability of reliable body segment inertia parameter (BSIP) estimates.Current processes to obtain these estimates involve many time consuming manual measurements human body, used in conjunction with models or equations.While such methods have become accepted standard they contain inherent errors arising from measurement and significant assumptions made underlying data form equations.Presented here is an alternative approach obtaining parameters...
