Integrated Prosthetic Leg Design Frameworks for People with an Above-Knee Amputation
… many amputees lack access to high-performance prosthetic components due to the cost and availability of continuous care. This thesis aims to design low-cost, high biomechanical performance above-knee prosthetic leg components (prosthetic foot and knee) that will result in a walking motion …

Design, Test, and Evaluation of a High Powered 4 DOF Prosthetic Leg for Transfemoral Amputees
A high powered 4 DOF prosthesis for transfemoral amputees is presented in this paper. The prosthesis utilizes series elastic actuators with high powered hobby grade helicopter motors capable of providing 2880~W of power each for knee and ankle pitch and ankle roll. In addition, a yaw motor with a …

Identification of design requirements for a high-performance, low-cost, passive prosthetic knee through user analysis and dynamic simulation
… to design a high-performance, low-cost, passive prosthetic knee for transfemoral amputees in India. The knee was primarily intended to improve the walking gait of amputees relative to existing low-cost devices. This thesis aimed to identify detailed design requirements for the prosthetic knee …

Inverse optimal control for differentially flat systems with application to lower-limb prosthetic devices
Powered prosthetic devices have shown to be capable of restoring natural gait to amputees. However, the commercialization of these devices is faced by some challenges, in particular in prosthetic controller design. A common control framework for these devices is called impedance control. The …

Hip and Knee Biomechanics for Transtibial Amputees in Gait, Cycling, and Elliptical Training
… status (amputated, control [non-amputated]), and leg (dominant [intact], non-dominant [amputated]). Ten unilateral transtibial amputees and ten control participants performed the three exercises while kinematic and kinetic data were collected. Hip and knee joint flexion angle, resultant forces, …

Distributed Feedback Control Algorithms for Cooperative Locomotion: From Bipedal to Quadrupedal Robots
… nonlinear control algorithms with application to legged robots. It explores both naturally decentralized problems in legged locomotion, such as the collaborative control of human-lower extremity prosthesis and the decomposition of high-dimensional controllers of a naturally centralized problem …

Reactive stepping strategies following lateral surface translations in individuals with a unilateral lower limb amputation
… strategies, particularly with the unloaded leg and when the direction of the perturbation causes unloading of the prosthesis. Amputee stepping strategies were characterized by fewer steps, lower quality of balance recovery, and wider variety compared to non-amputees. This study's findings …

Achieving Near-Natural Locomotion in Transfemoral Amputees - A Control Theoretic Approach
… the individual has to be fitted with a prosthetic limb to regain mobility. While a good-fitting, well-designed prosthetic device can help support body weight and locomotion, the loss of lower limb muscles profoundly impacts body support, and stability and often results in asymmetrical …
