Abstract:

Millions of people are suffering from lower limb loss all around the world. Passive ankle prostheses in the market cannot fully restore ankle function and will cause asymmetrical walking gaits. Several powered ankle prostheses, which provide net power in the stance phase to assist walking, have been developed by the researchers, but their walking range is significantly limited by the power requirement. In this thesis, an electrohydrostatic actuator (EHA) powered ankle prosthesis is proposed. This is intended to actively assist walking at certain points in the gait cycle, namely the plantarflex

Abstract:

Ideal prostheses are defined as artificial limbs that would permit physically impaired individuals freedom of movement and independence rather than a life of disability and dependence. Current lower limb prostheses range from a single mechanical revolute joint to advanced microprocessor controlled mechanisms. Despite the advancement in technology and medicine, current lower limb prostheses are still lacking an actuation element, which prohibits patients from regaining their original mobility and improving their quality of life. This thesis aims to design and test a Pneumatic Artificial Muscle

Abstract:

In Germany alone, 10,000 to 12,000 transfemoral amputations occur every year. Persistent rehabilitation efforts and advanced medical devices like prosthetic knee joints are crucial to reintegrating amputees into daily life successfully. Modern knee joints represent a highly integrated mechatronic system including special kinematics, a lightweight design, various sensors, microprocessors and complex algorithms to control a damping system in the context of the given situation. A knee joint is a passive system and normally has no actuator for an active movement. To enable a natural gait pattern,

Sports technology can be any product or system used to facilitate, train or influence an athlete’s performance. The role of prostheses used for disability sport was initially to help facilitate exercise and then ultimately, competition. In able-bodied sport, controversy has occasionally been caused through the adoption or introduction of sports technology. However, scant attention has been paid to sport with a disability with respect to such concerns.

As is well known, users can make significant contributions to innovations, including innovating themselves. However, much work on user innovation has focussed on developed countries. The question remains whether and how users innovate in a developing country setting. Bodies of literature that explicitly consider innovations in such settings emphasise the influence of limitations. This thesis therefore investigates how limitations shape the creation and sharing of innovations by users.

Abstract:

Misalignment in the lower limb prosthesis can cause great discomfort in the stump- socket interface and disturbance to gait function. In the long run, it could deteriorate the musculoskeletal system. In practice, the assessment still depends heavily on the verbal feedback of an amputee and experiences of a prosthetist. Moreover it is inconsistent amongst the prosthetists. Prosthetic alignment involves the adjustment of the prosthetic components relative to the gait quality. Some methods were proposed, including symmetry index, variation in a step-to-step transition, stability within the zone o

Abstract:

Alignment of the above-knee prostheses is one of the important factors affecting the success of patient/prosthesis matching. It has been found that the prosthetist and the patient can accept a number of alignments which produce different intersegmental loads and it has been suggested that it is possible to obtain an 'optimal' alignment satisfying certain criteria. In order to enhance the efficiency of the alignment procedure, it is necessary to understand how alignment affects the amputee's gait and the patient compensations for changes in the alignment.

Abstract:

Relative motion between residual limb and prosthetic socket is an indication of poor fit.

Although numerous methods exist to measure the relative motion, all have limitations and are not well suited for clinical use. A measurement system using optical sensors has been proposed by students at the Technische Universität Darmstadt and evaluations of a functional model have yielded promising results.

Human upright locomotion emerged about 6 million years ago. It is achieved by a complex interaction of the biological infrastructure and the neural control. Bones, muscles, tendons, central nervous commands and reflex mechanisms interact to provide robust and efficient bipedal movement patterns like walking or running. Next to these locomotion tasks humans can also perform complex movements like climbing, dancing or jumping. Diseases or traumatic events may cause the loss of parts of the biological infrastructure or the ability to control the lower limbs. Thus an identification of the required

However, existing methods in balance and mobility analysis fail to provide sufficient sensitivity to detect changes in prosthesis users' postural control and mobility in response to clinical intervention or experimental manipulations and often fail to detect differences between prosthesis users and non-amputee control subjects. This lack of sensitivity limits the ability of clinicians to make informed clinical decisions and presents challenges with insurance reimbursement for comprehensive clin

Abstract:

碩士<br>國立陽明大學<br>醫學工程研究所<br>98<br>Background: The direct skeletal attachment of prosthetic limbs (osseointegrated prostheses) has been suggested to be an excellent alternative to lower-limb amputees having problems with their traditional prostheses. However, it has not been adopted universally due to the issues of ensuring mechanical fixation to the bone. Considerations are given to mechanisms of mechanical failure of the implant system and the femur as well as bone-remodeling subsequent to the altered loading conditions. Method: Using “Finite element model” to simulate the actual conditions.

Abstract:

abstract: Robotic lower limb prostheses provide new opportunities to help transfemoral amputees regain mobility. However, their application is impeded by that the impedance control parameters need to be tuned and optimized manually by prosthetists for each individual user in different task environments. Reinforcement learning (RL) is capable of automatically learning from interacting with the environment. It becomes a natural candidate to replace human prosthetists to customize the control parameters. However, neither traditional RL approaches nor the popular deep RL approaches are readily sui

Abstract:

Although dynamic prosthetic alignment is an important process for the rehabilitation of transtibial amputees, such alignment technique is subjective and inconsistent. Using biomechanical variables and questionnaire assessments, this study compared an instrument-assisted dynamic alignment technique using the Compas™ system and conventional alignment techniques on nine adults with unilateral transtibial amputation. A focus group discussion was conducted with six prosthetists to understand clinical practice of dynamic alignment and their perception of the Compas™ system. Results found that Compas
