A Sensor for Three-Dimensional Limb-to-Prosthesis Interface Motion and Physiological Adaptations from Lower Extremity Prosthesis Use
Lower extremity prosthesis use following amputation introduces stark environmental changes to the skin and underlying tissue of the residual limb. As prosthesis socket fit is considered one of the most integral elements of increasing the likelihood a user adopts their artificial limb, it is crucial …

Development of an optimum acetabular cup prosthesis
… Analysis to produce a novel acetabular cup prosthesis. An investigation into current static and fatigue testing procedures for acetabular cup prostheses has identified current strengths and weakness and proposes a cheap, fast method that is closer to anatomical loading conditions. The …

Eye movement studies with a vestibular prosthesis/
… cochlear implants for the deaf. This vestibular prosthesis provides pulsatile electrical stimulation to the vestibular nerve. Prosthesis effectiveness is assessed using the vestibulo-ocular reflex (VOR), since the VOR helps stabilize gaze in healthy individuals by evoking eye movements that …

Ογκολογικές προθέσεις εγγύς μηριαίου - Proximal femur tumor prosthesis
Οι κακοήθεις νεοπλασίες αποτελούν τη δεύτερη κυριότερη αιτία θνησιμότητας παγκοσμίως, με προβλεπόμενη αύξηση της θνησιμότητας τα επόμενα έτη. Το εγγύς τμήμα του μηριαίου οστού αποτελεί συχνή περιοχή ανάπτυξης πρωτοπαθών οστικών σαρκωμάτων, όπου τα σαρκώματα Ewing, τα χονδροσαρκώματα και τα …

Electric stimulation parameters for an epi-retinal prosthesis
… contribute to the development of an epi-retinal prosthesis which may someday restore vision to patients blinded by outer retinal degenerations like retinitis pigmentosa. By stimulating surviving cells in tens or hundreds of distinct regions across the retinal surface, the prosthesis might convey …

Design of a novel anterior cruciate ligament prosthesis
Injuries to the anterior cruciate ligament (ACL) are extremely common (approximately 100,000 every year in the US) and result in greatly reduced mobility; although several surgical procedures have been devised to address this condition, they are far from being completely satisfactory. The golden …

Biologically inspired autoadaptive control of a knee prosthesis
… describes the electronic control of a knee prosthesis for amputees. A microprocessor receives data from sensors, processes it and determines the proper level of rotary resistance for the joint. Control is maintained through one of two algorithms -- one for a system with sensors only for knee …

Encapsulation of electronic components for a retinal prosthesis
Long-term success of an implantable retinal prosthesis depends on the ability to hermetically seal sensitive electronics from a saline environment with an encapsulant material. Furthermore, the retinal implant project's proposed laser-driven prosthesis requires that the encapsulation material be …

Computational Stress and Deformation Analysis of Mammary Prosthesis
A linear and non-linear material model for the breast implants was developed through axial tension testing, while linear and non-linear breast tissue models were assumed based on smooth muscle. These material models were to develop axisymmetric finite element models to determine the stresses in the …

Modeling Upper Body Kinematics While Using a Transradial Prosthesis
… anatomical joints transradial (below the elbow) prosthesis users lose at least two of the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation …

Redesigning a prosthesis for a golfer with transhumeral amputation
… thesis was to determine the motions needed in a prosthesis that would enable a transhumeral amputee professional golfer, Michael Gibson, to play golf with similar dynamics to those of a two-armed golfer. Although he plays golf well using only one arm, his swings tend to have less power and are …
