Abstract:

Myoelectric prostheses are designed to provide cosmesis and a degree of upper limb functionality for people with upper limb absence. However, self-reported rejection rates remain stubbornly high, with control of the prosthesis being commonly cited as one of the primary reasons. This observation may indicate that the significant engineering efforts aimed at improving prosthesis control may not have been addressing the most important issues. Surprisingly, there has been no empirical work outside of lab environments to understand the relative importance of key factors affecting prosthesis control

Abstract:

This thesis is a development project for a myoelectric prosthetic hand. That means a mechanical hand that is controlled and actuated by the user's own muscles on the residual limb. The thesis has led to a theoretical concept of a complete prosthesis and a non-complete physical prototype that provides proof of concept and functions. The thesis was as a means of providing the mechanical development of an alternative model of the prosthesis that is more functional and has the ability to offer the users a lower price than current models. The foundation of the project is that the development has be

Abstract:

The last few decades have witnessed an immense effort to develop working retinal implants for patients suffering from retinal degeneration diseases such as retinitis pigmentosa. However, it is becoming apparent that this approach is unable to restore levels of vision that will be sufficient to offer significant improvement in the quality of life of patients. Herein, a new type of retinal prosthesis that is based on genetic expression of microbial light sensitive ion channel, Chanelrhodopsin-2 (ChR2), and a remote light stimulation is examined. First, the dynamics of the ChR2 stimulation is cha

Abstract:

Most sarcomas of the bone occur in patients of a relatively young age including skeletally immature patients. Approximately 50 child sarcomas are treated with limb salvage surgery per year in the United Kingdom. These children need an extendible implant that can be lengthened periodically to keep pace with the growth in the opposite limb. Surgically, invasive devices have been used for the past thirty years with intrinsic problems of infection and long-term recurrent trauma to the patient. To eliminate problems associated with the invasive device I have attempted to develop a non invasive exte

Background Recent conflicts have seen an increase in trauma related military amputees who incur complex injuries which result in varied residual limbs. In many cases these amputees have been provided with state of the art (SOTA) components with the expectation that they will transfer into NHS care after military discharge. However, there is a lack of knowledge around how prosthetic prescriptions are made in both the MOD and NHS, including patient involvement. It is important to explore prosthetic prescription decisions to enhance the quality, consistency and equity of care delivery for trauma

Abstract:

Restoring vision to the blind has been an objective of several research teams for a number of years. It is known that spots of light -- phosphenes -- can be elicited by way of electrical stimulation of surviving retinal neurons. Beyond this, however, our understanding of prosthetic vision remains rudimentary. To advance the realisation of a clinically viable prosthesis for the blind, a versatile integrated circuit neurostimulator was designed, manufactured, and verified. The neurostimulator provides electrical stimuli to surviving neurons in the visual pathway, affording blind patients some f

However, the existing method using inorganic materials and multi-layered polymers requires long material preparation time and expensive processing cost due to the requirement of microfabrication tools and complicated transfer printing steps

Abstract:

Retinal prostheses require the presence of viable population of cells in the inner retina. Evaluations of retina with Age-Related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP) have shown a large number of cells remain in the inner retina compared with the outer retina. Therefore, vision loss caused by AMD and RP is potentially treatable with retinal prostheses. Photostimulation based retinal prostheses have shown many advantages compared with retinal implants. In contrary to electrode based stimulation, light does not require mechanical contact. Therefore, the system can be complete

The purpose of this study is to try to cancel the effect motion artifacts have on myoelectric prosthesis control, in order to avoid unsolicited prosthesis behaviour.

The current trend of performing Total Hip Replacements(THR) on younger patients incurs an increasing number of revisions.

Amputee gait is characterised by a higher metabolic cost of walking compared with anatomically intact subjects. Anatomically intact gait kinetics reveals that tendons crossing the ankle joint store and return strain energy during the stance phase of walking to provide forward propulsion. One of the main reasons for the high-energy cost of amputee gait is that passive prosthetic feet store little energy compared with the equivalent human structure and hence cannot provide the required energy at push-off. In addition, passive prosthetic feet are uncontrolled in the storage and release of strain

Abstract:

Total hip replacement (THR) is one of the most successful and most frequently performed operations. For most implants the published rate of revision at 10 years is less than 10%. However the revision rates are higher for younger and more active patients who are likely to outlive their implants. The most frequent cause of THR failure is aseptic loosening, commonly accompanied by bone loss at the implant site. THR revisions give worse functional results and fail sooner than primary THR and are complicated by this loss of bone stock. A resurfacing hip prosthesis replaces the diseased surface laye
