چکیده
The paper discusses results of experiments carried out at healthy individuals with an aim to establish an in-house developed sensor mechanism using ADXL 330 accelerometer. The sensor was developed in view to measure gait phases (heel strike & toe off), gait duration and gait speed. These findings were useful in understanding the range of normal gait though accelerometer and further used for control of indigenously developed artificial electronic knee.

Design and Evaluation of a Magnetorheological Damper Based Prosthetic Knee
In this work, a magnetorheological (MR) damper based above-knee prosthesis is design and evaluated based on its performance in swing phase and in stance phase. Initially, a dynamic system model for swing phase of a prosthetic leg incorporating a single-axis knee with ideal MR damper was built. The dynamic properties of the damper are represented with Bingham parametric model. From Bingham model...

Gait as an effective factor in controlling obesity is very important in human motor development. Thus, the purpose of this study was to examine the effects of obesity and slimming on the gait kinematics in children. Methods:...
متن کاملThe Comparison of Gait Kinematics in Over-Weight and Normal-Weight People across Age Groups
Objective Obesity and overweight have changed to very important factors in people movements in the modern world. Therefore, the present study was carried out to examine the effects of overweight on gait kinematic factors in children, young adults, middle-aged, and older adults. Methods The present study was a causal-comparative study in which 40 participants aged 9-85 were selected based on pu...
متن کاملPassive Controller Design for Swing Phase of a Single Axis Above-Knee Prosthesis
In this research we design a passive controller for an above knee prosthesis. The controller is a linear spring and damper for swing phase motion, parameters of which determined via optimization of adjustment of the prosthesis shank motion with a desired shank angle trajectory comes from experimental data. In this way, we exerted a certain thigh motion, hip movement included, into the system as...
متن کاملEffect of different walking speed on the gait kinematics of individuals with knee varus
The purpose of current study was to investigate the spatio-temporal gait parameters and knee varus angle during walking at different speeds in young with knee varus. 18 subjects with varus deformity classified at grade 3 of bowleg and 17 healthy subjects, volunteered to participate in this study. The following variables include stance, swing, double support and cycle time, cadence, stride le...
