Assessment of aerobic capacity and walking economy of unilateral transfemoral amputees.
BACKGROUND Studies of the maximal oxygen uptake (VO(2max)) of transfemoral amputees have mostly used protocols that activate a relatively small muscle mass. Consequently, transfemoral amputee VO(2max) may be systematically underestimated, and the validity of these test protocols is questionable. OBJECTIVES (1) Investigate validity and reliability of a VO(2max) walking protocol and (2) compare...
متن کاملEffect of Asymmetric Knee Height on Gait Asymmetry for Unilateral Transfemoral Amputees
Transfemoral prostheses have traditionally sought to emulate symmetry in their designs. Using a symmetric prosthesis for a physically asymmetric unilateral transfemoral amputee typically causes asymmetric gait patterns. This research study investigates the effects of prostheses with lower knee heights than the intact knee and a pilot study of the combined effects of adding distal mass with lowe...
متن کاملJoint Moments of Unilateral Transfemoral Amputees Using Running-specific Prosthesis during Sprinting
The aim of this study was to investigate the bilateral difference of the joint moments between an intact leg (INT) and a prosthetic leg (PST) in unilateral transfemoral amputees (TFAs) wearing running-specific prosthesis during sprinting. Eight sprinters with unilateral TFAs performed maximal sprinting on a 40-m runway with 7 force platforms located in between. Hip and knee joint extension and ...
متن کاملMechanical Engineering Control Methodologies for Powered Prosthetic Interventions in Unilateral and Bilateral Transfemoral Amputees
This dissertation describes the development and testing of control systems for powered transfemoral prostheses. The work is divided into seven chapters, with five distinct contributions. Chapter I provides introductory material, background, and some of the theoretical motivations behind the work. In Chapter II, a finite statebased locally passive impedance controller is described based on previ...
متن کاملGait improvement in unilateral transfemoral amputees by a combined psychological and physiotherapeutic treatment.
A conscious therapeutic approach was used combining methods in physiotherapy with psychological awareness to re-educate nine transfemoral amputees during 10 months in outdoor environments. All were rehabilitated trauma or tumour cases, mean age 33 years, and had worn their prostheses for more than 18 months. The method aimed at integrating the prosthesis in normal movements and increasing body ...
