Prosthetic Realities, Prosthetic Futures: Challenging the status quo of external breast prosthesis design
… the need and opportunity to update the design approach used in the production of external breast prostheses (EBP) for women post mastectomy. Spurred by accounts of some women’s negative experiences with their EBP, this research took influence from colour psychology, emotional design and …

Prosthesis Design and Object Recognition Based Grasping of a 3D Printed Anthropomorphic Artificial Hand
This work presents the design of a cost effective, open-source, 3D printed prosthetic hand with the implementation of object recognition in order to reduce the cognitive burden of amputees through automated grasping. Due to the high cost of modern, active, prostheses, an open-source 3D printable …

The beauty of prostheses : designing for female amputees
… and aesthetics of the natural human body. A prosthesis is carefully designed to provide optimal functionality to assist the amputee in returning back to her normal daily activities as much and as independently as is possible. However, when an amputee wears her prosthesis, the prosthesis also …

Geometric morphometrics for 3D dense surface correspondence: population comparisons of shoulder bone morphology
… for diagnosis and provides knowledge for prosthesis design. The distribution of the data in the modified PCA space was shown to converge to a stable distribution when more vertices/landmarks are used for the analysis. South African and Swiss datasets were shown to be more distinguishable …

Spatial mechanisms for modelling the human ankle passive motion
… human ankle joint complex is fundamental for the design of relevant surgical treatments. The dissertation presents a possible improvement of this knowledge by a new kinematic model of the tibiotalar articulation. In this dissertation two one-DOF spatial equivalent mechanisms are presented for the …

Grasped Object Detection for Adaptive Control of a Prosthetic Hand
… by trauma or birth congenital defects. Several prosthesis options are commercially available, including electric powered prostheses. A review of surveys for upper limb prosthesis users have indicated improvement opportunities in the prosthesis design as well as improved functionality and …

Ultrasonic imaging methods for quantitative musculoskeletal tissue assessment and improved prosthetic interface design
… cup-like interface connecting the residuum to prosthesis - is considered the most critical component. It must be custom-made and tailored to each individual user, and if not fit properly can significantly hinder quality of life. As an alternative to conventional fabrication practices that …

Probabilistic finite element analysis of the uncemented total hip replacement
… of a total hip replacement(THR), such as prosthesis design and material properties, applied loads, surgical approach, femur size and quality, interface conditions etc. All these factors are subject to variation and therefore uncertainties have to be taken into account when designing and …

The Study of Compensatory Motions While Using a Transradial Prosthesis
… knowledge of how the body adapts. A transradial prosthesis without a dynamic wrist component may cause awkward compensatory motion leading to fatigue, injury or rejection of the prosthesis. This work analyzed the movements of shoulder, elbow and torso during four tasks: drinking from a cup, …

The mechanical and magnetic behaviour of sintered fibre networks and their suitability for a therapeutic, biomedical application
… metallic fibre networks have been used in the design of a range of technical devices in the past years (e.g. heat exchangers or catalysts). One potential application in the field of therapeutic, biomedical engineering is the magnetic-mechanical stimulation of bone growth around prosthetic …

Mechanical design and analysis of implantable components for a retinal prosthesis
The success of a retinal prosthesis in restoring vision to blind patients will be dependent on its long term viability when implanted in the eye. This thesis addresses mechanical aspects relating to the biocompatibility of the device and its ability to survive in a saline environment. Chronic …

An articulated skeletal analogy of the human upper-limb
… that the previous limitations placed on prosthesis design may be challenged. Therefore, it is appropriate to look for new design archetypes.</p> <p>This thesis describes the development, implementation and evaluation of mechanical analogies of the skeletal components of the human hand and …

Hip and Knee Biomechanics for Transtibial Amputees in Gait, Cycling, and Elliptical Training
… Current state-of-the-art prosthetic leg design is insufficient in restoring natural biomechanics not only in gait but also in cycling and elliptical training. Improved prosthesis kinematics that restore non-dominant knee flexion in amputees to normal levels could help reprogram quadriceps …

Design and development of a sensory feedback system for transradial amputees using body powered prostheses
… advancements have been made in the realm of prosthesis design over the last two decades, amputees still reject their prostheses largely owing to the lack of sensory feedback received. The aim of this study was to develop a non-invasive sensory feedback system, including proprioceptive …

An Overview on the performance of sprinters with lower limb amputation/impairment in Paralympic Games.
… Over the last few decades carbon fibre prosthesis has developed considerably and it has facilitated running activity for amputees. The evaluation of such technologies is now urgently required as the use of carbon fibre prosthesis is now being investigated through justice and legal …
