Filter by:The initial purpose of this study is to develop a prosthesis which is adjustable to use with a variety of patients in aquatic therapy. Aquatic therapy is a beneficial rehabilitation tool for individuals with limb loss. The pool environment offloads body weight, which can improve comfort on a residual limb and increase confidence in activities outside of the pool. The properties of water also assist in strengthening exercises and reducing pain. Currently, most individuals do not have a prosthesis to use in the pool. Water specific prosthesis are often not covered by insurance and can be expensive. For someone that doesn't have a water specific prosthesis, they may not be able to do therapy tasks on two legs, limiting what activities or exercises can be performed. Through creating an adjustable prosthesis, it will allow persons with limb loss to have access to a water specific leg in a time efficient, cost effective, and safe manner for rehabilitation. This study involves a novel prosthesis for use in aquatic therapy. This novel design will have an adjustable circumference, residual limb length, and height, allowing a greater number of patients to use the prosthesis.
The goal of this prospective longitudinal observational cohort study is to determine the nutritional intake, nutritional status, and physical activity level in people who have undergone a major dysvascular lower limb amputation (LLA) at different moments post-LLA (during hospital admission several days post-LLA, and at 5 weeks, 6 months, and 9 months post-LLA). The main questions this study aims to answer are: - What is the nutritional intake, nutritional status, and physical activity level at different moments post-LLA? - What is the association between nutritional intake and physical activity level, and nutritional status? - What is the association between nutritional intake, nutritional status and physical activity level and clinical outcomes (mortality, wound healing, quality of life, physical functioning)?
This research was planned to examine how unpredictable movements on the support surface will affect muscle activation and kinematic parameters in individuals with transtibial and transfemoral amputations. Individuals aged between 18-45 years, using prostheses for at least 1 year, able to stand and walk independently without a walking aid, and volunteered to participate in the study with unilateral transtibial and unilateral transfemoral amputation, and healthy individuals similar to these individuals in terms of age and gender will be included in the study.
The PERCEIVE (PrEdiction of Risk and Communication of outcomE followIng major lower limb amputation - a collaboratiVE study) study aims to explore how decisions about major lower limb amputations are made by patients and healthcare professionals.
This study is designed to learn more about decision making for prosthetic design, with the goal of producing a decision making aid for prosthetic design decisions.
The focus of this study is to conduct a clinical study in individuals with transradial amputations to compare function using a 1-DOF or 2-DOF wrist. All prostheses will be attached to a single DOF Otto Bock hand and controlled using a pattern recognition system equivalent to the Coapt system. This study will enable the investigator to quantify the relative functional value of powered wrist flexion during both in-laboratory testing and home use. In addition, the investigators will address the effectiveness of different hand-wrist combinations to enhance patient-centered clinical decision making.
The objective of the proposed work is to enhance understanding of the potential benefits of adjustable sockets and inform clinical decision making.
The goal of this research is to analyze data from smartphone-based and wearable sensors, using advanced machine-learning and data-mining techniques, and to combine this information with performance-based measures, participant-reported measures, and structured interviews to create a clinical toolbox to (i) identify individuals who exhibit reduced prosthesis use (compared to expected usage levels based on K-level designation and/or participant goals of community mobility and social interaction), (ii) identify prosthetic/physical and psychological factors that limit prosthesis use, and (iii) determine the effect of targeted interventions to increase prosthesis use and facilitate achievement of participant goals. Objective sensor-based measurement of home and community activities will allow for the correlation of real-world function to in-clinic assessments and to monitor changes resulting from rehabilitation interventions in real time. Machine-learning and data mining techniques will be used to identify a subset of measures from this toolbox that sensitively and accurately reflect real-world function, enabling clinicians to predict and assess activity and provide effective interventions to optimize prosthesis use. The goal of this project, to improve overall performance with respect to activities of daily living and other real-world activities, thus addresses the Fiscal Year 2017 (FY17) Orthotics and Prosthetics Outcomes Research Program (OPORP) Focus Area of Orthotic or Prosthetic Device Function.
The study concerns the technique of osseointegration that consists of inserting a titanium pin into the bone of the amputated limb. A removable external prosthesis will then be connected to the implant section that protrudes from the soft parts. The benefits of using an osseointegrated prosthesis are the improved sensory feedback (osseoperception) and absence of the socket. This leads to better anchoring of the prosthesis to the abutment, greater control of the prosthesis and the absence of heat, pain, and pressure sores. The osseointegrated prosthesis does not reduce the mobility of the limb and promotes good growth of bone and muscle mass. The aim of this study is to evaluate the stability of the osseointegrated implant in trans-femoral and trans-humeral amputees. The main outcome: quantitative evaluation (rotations, translation and MTPM) of the stability of the implant bone interface by Roentgen Stereo-photogrammetric Analysis (RSA) and follow-up. The secondary outcome: evaluation of the quality of life improvement in patients through clinical score and satisfaction survey.
The e-OPRA Implant System, is a further development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System, approved under HDE (Humanitarian Device Exemption) H080004. The e-OPRA Implant system is an implant system for direct skeletal anchorage of amputation prostheses. The added feature in the e-OPRA Implant system, is a bidirectional interface into the human body that allows permanent and reliable communication using implanted electrodes. These electrodes will provide long-term stable bioelectric signals for an improved control of the prosthetic limb. The purpose of the study is to evaluate the feasibility of a lower limb amputee with the e-OPRA Implant System exhibiting full neural control over a neuro-mechanical prosthetic system. A maximum of six subjects will be enrolled. Each subject will undergo a surgery where the e-OPRA Implant System will be implanted. The subjects will participate in follow-up sessions of which the last one occurs approximately 24 months after the surgery. This is a prospective, non-randomized, uncontrolled study.
