چکیده

Based on a mathematical model of the human gait, a Matlab 2010a algorithm is presented to predict the reaction forces and moments in a particular point along the socket linked to the lower limb of a transfemoral amputee. The model takes the inertia developed due the swing of the limb during the gait into consideration. A validation of the results is made with the data obtained in a gait lab, and the model results are consistent with those obtained in the gait lab.

Piezoelectric Bimorphs' Characteristics as In-Socket Sensors for Transfemoral Amputees

Alternative sensory systems for the development of prosthetic knees are being increasingly highlighted nowadays, due to the rapid advancements in the field of lower limb prosthetics. This study presents the use of piezoelectric bimorphs as in-socket sensors for transfemoral amputees. An Instron machine was used in the calibration procedure and the corresponding output data were further analyzed...

Relationship between socket pressure and EMG of two muscles in trans-femoral stumps during gait.

The biomechanical interaction between the leg stump and the prosthetic socket is critical in achieving close-to-normal ambulation. Although many investigations have been performed to understand the biomechanics of trans-tibial sockets, few studies have measured the socket interface pressure for transfemoral amputees. Furthermore, no report has examined how the residual muscle activities in the ...

Questionnaire for Persons with a Transfemoral Amputation (Q-TFA): initial validity and reliability of a new outcome measure.

The Questionnaire for Persons with a Transfemoral Amputation (Q-TFA) is a new self-report measure developed for nonelderly transfemoral amputees using a socket- or osseointegrated prosthesis to reflect use, mobility, problems, and global health, each in a separate score (0-100). This paper describes the initial measurement properties of the Q-TFA as completed by 156 persons with a transfemoral ...

Numerical Analysis and Comparison of Femur Bone in Osseointegrated Amputees and Non Amputees during Daily Activities Bilal

Currently available implants for osseointegration in transfemoral amputees are OPRA system and ISP System which shows many advantages over conventional socket fixation. To overcome the limiting issues like periprosthetic bone losses in osseointegration, a new design was developed. The analysis of both OPRA and New design was compared with a normal femur bone during daily activities. The results...

Knee Compression Forces in Transfemoral Amputees Using C-leg and 3r60 Prosthesis

INTRODUCTION Previous studies investigating knee compression forces in normal subjects have found forces of 3-4.6 times body weight during normal walking [1,2]. The purpose of the present study was to quantify the knee compression forces in transfemoral amputees and to investigate the effect of two different prostheses (C-leg vs. 3R60) on this parameter. Transfemoral amputees depend heavily on ...
