Filter by:The goal of this proposed project is to gather community-based data from the K2-level Transfemoral Amputee (TFA) population to aid in evidence-based prescription of powered prosthetic knees (i.e., choosing the right device to maximize the benefit for each patient). The investigators intend to use this trial data along with a concurrent study being conducted within the K3-K4 level population to guide the implementation of effective prescriptions towards those that can benefit most from a given device and limit prescription to those who would not see benefit in order to ensure the most judicious use of Department of Defense (DoD) and Veteran's Affairs healthcare dollars. The findings will also be shared with the research community to help drive the design of future devices by identifying what features and functions are most beneficial to which patient populations when the devices are used outside of the laboratory. In summary, more community-based data on how powered prosthetic knees compare with the current standard in TFA populations is needed to allow for improved clinical decision making and clinical outcomes.
The goal of this observational study is to investigate the effectiveness of NMPKs versus MPKs in persons with an LLA in the standard healthcare system in the Netherlands taking all levels of the ICF model into account. Our main aim is to assess the effect of MPK use compared to NMPK use on walking distance, as this is one of the most used outcome variables in literature and thus enables comparison with previous studies. Our secondary aim is to investigate the effect of NMPKs versus MPKs on all ICF-levels: body structures and function, activities and participation. Participants will be seen four times in a year. During these measurement moments they will: - Perform two physical tests - Fill out a set of questionnaires - Wear an activity tracker for one week
This study will aim at performing biomechanical analyses of the actual load applied on the end of the stump (residuum) of individuals with transfemoral limb loss fitted with bionics bone-anchored prostheses during activities of daily living. The assessment of the inner prosthetic loading will rely on the analyses of common activities of daily living (e.g., walking in straight line and around circles, ascending and descending stairs and slopes, cycling, etc.) performed in experimental and/or clinical and/or open environments. The biomechanical analyses of the load will address the following research questions: A. What is the actual magnitude of the forces and moments applied on transfemoral osseointegrated implant by Rheo Knee and Power Knee during activities of daily living? living? B. What are the determinants of the loading profile in relation to the demographic and anthropometric characteristics, the type and level of activities as well as type, fitting and alignment of Rheo Knee and Power Knee? C. How the loading profiles applied by Rheo Knee and Power Knee compared to usual MPKs and Non-MPK considered below standard of care? Biomechanical data will be collected through a typical cross-sectional cohort study. Each participant will be assessed with a given prosthesis at one particular time (i.e., exposure and outcomes will be both measured at the same time). These biomechanical analyses will rely on already published protocols (e.g., study design, instrumentation setup, extraction of loading profile). Protocols to record load data have been well described by PI-Frossard in over 20 peer-review publications in top-ranked journals. The protocol used in this study has been acknowledged, validated and are commonly used within the fields of biomechanics and prosthetics. The outcome of this study will increase the basic understanding about the effects of loading on the interaction between body and prosthesis (e.g., osseointegration between residual bone and implant). The study will also increase applied knowledge required to establish stronger evidence-based rehabilitation programs, fitting of prosthetic limbs and design of bionics prosthetic components. It is anticipated that, both basic and applied knowledge gain in this study will, all together, contribute to increase the health-related quality of life of individuals fitted with socket and bone-anchored prostheses.
Studies have shown that Pilates exercises are one of the exercises that can improve breathing capacity, coordination, balance, flexibility, and muscular endurance. Pilates exercises improve walking and balance, reduce back pain and prevent further pain or injury. These are all common problems for people who have undergone lower extremity amputation. The aim of our study is to improve the pelvis-trunk coordination, gait symmetry, and balance on individuals who have undergone amputation and also to increase body awareness.
The goal of this proposed project is to gather community-based data from the K4-level Transfemoral Amputee (TFA) population to aid in evidence-based prescription of powered prosthetic knees (i.e., choosing the right device to maximize the benefit for each patient). The investigators envision that this Level 1 submission will transition into a larger follow-on Level 2 trial that will explore a larger spectrum of patient populations (K2-K4), as well as testing additional Power Knees currently in development that are expected to become commercialized in the near future. The investigators intend to use this Level 2 trial data to guide the implementation of effective prescriptions towards those that can benefit most from a given device and limit prescription to those who would not see benefit in order to ensure the most judicious use of Department of Defense (DoD) and Veteran's Affairs healthcare dollars. The findings will also be shared with the research community to help drive the design of future devices by identifying what features and functions are most beneficial to which patient populations when the devices are used outside of the laboratory. In summary, more community-based data on how powered prosthetic knees compare with MPKs is needed to allow for improved clinical decision making and clinical outcomes.
Our goal is to understand the critical factors associated with outcome acceptance following upper limb loss. We aim to develop a unified theoretical model that describes the psychosocial experience of upper limb prosthesis use and predicts outcome acceptance following upper limb loss. This conceptual framework will enable clinicians and researchers to evaluate and predict patient outcomes following limb loss, and to design interventions that improve outcomes. The proposed two-year study is a mixed methods (qualitative and quantitative) study using an observational design. The qualitative component of the study will involve data collection through telephone interviews with 18 participants and analyses using a grounded theory approach with constant comparison methods. The quantitative component involves administration of standardized measures quantifying constructs of the theoretical model in 120 participants and analyses to produce a structural equation model of outcome acceptance. Participants will include persons with unilateral acquired upper limb loss at the trans radial or trans humeral level who use currently available prosthetic devices.
The primary objective of this investigation is to evaluate how the CONNECT TF compares to traditional handmade sockets, specifically that it provides reliable suspension and improved usability and comfort for the amputee, and that it enables single clinical visit for fitting.
Obesity and other associated complications promote the development and the progression of osteoarthritis. The subcutaneous and abdominal fat release several factors that alter bone and the cartilage. The role of the marrow fat in close connection with bone has not been defined yet, whereas cellular and animal models indicate that this fat depot modifies bone and cartilage. The aim of the study is to define if the marrow fat produces more joint-altering factors by comparison with subcutaneous fat. This fat depot can be characterized from removed pieces during the prosthetic surgery of the knee. Measuring before surgery the body weight, waist and hip circumferences, blood pressure, glucose, insulin and lipids in blood will also allow to determine if obesity and/or type 2 diabetes make this fat more dangerous for the joint. Such research will allow the elaboration of new therapeutic strategies in osteoarthritis.
Individuals living with Transfemoral Amputation, enrolled equally at the Veterans Affairs New York Harbor Healthcare System (VANYHHS) and Walter Reed National Military Medical Center (WRNMMC), will be fit with a powered ankle-foot prosthesis. All subjects will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment at baseline utilizing their current passive prosthesis. Subjects will then be randomly assigned into 2 equal groups: Powered device with an 8-session intensive, device-specific PT intervention (Group A); or powered device with current standard of practice (Group B), with includes basic device education, but no PT intervention. Subjects in Group A will undergo a 4-week PT-based intervention, which will isolate the contribution of device specific effects from rehabilitation effects. Group B will receive the current standard of practice, which does not include any formal rehabilitation. All users will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment after 4- and 8-weeks of use.
This study is designed to evaluate the feasibility of The Adaptive Neural Systems Neural-Enabled Prosthetic Hand (ANS-NEPH) system.
