Filter by:The trial is designed to test the effectiveness of a force-feedback cuff in combination with a myoelectric prosthesis in conveying information on grasp strength to the user, as well as the user's preference regarding the feature.
The aim of this study is to investigate the Reliability and construct validity of the Turkish version of the Prosthesis donning and doffing questionnaire in transtibial amputees.
Stump and phantom pain after amputation are common, but the responsible mechanisms are still not clarified. It has been suggested that phantom limb pain can be reduced by regional anaesthesia and in several recent studies, pain was reduced following intrathecal and intraforaminal blocks. In this study, the investigators want to investigate if spontaneous and evoked pain in amputees will be relieved by regional nerve blocks involving the damaged nerves.
This study was conducted to examine the effect of visual feedback on function, stability and quality of life in transtibial amputees. A total of 24 subjects who had unilateral transtibial amputations, used prosthesis with total surface bearing socket (TSB) for at least 1 year and volunteered to participate in the study were included. Before and after Treatment subjects were evaluated with "LASAR Posture" for prosthetic weight bearing (PWB), "Berg Balance Scale (BBS)" and "Timed Up& Go Test (TUG)" for balance and functional mobility, "2-Minute-Walk-Test (2MWT)" for physical performance, "Satisfaction with the Prosthesis Questionnaire (SATPRO)" for prosthetic pleasure and "Nottingham Health Profile (NHP)" for health- related quality of life. Participants were randomly divided into two equal groups as study and control groups. After the evaluations the same exercises; PWB exercises, balance exercises, anteroposterior and lateral weight shifting, obstacle course, walking on different grounds were applied to the the study group with visual feedback methods and control group.
Targeted Muscle Reinnervation increases the control signals available for commercial arm systems. A new type of control, pattern recognition, has been developed into a form that allows use with commercially available arm system. The goal of this project is a home trial, in which people who have had TMR will try the new controls and the new arm to find out if they are better than what is currently available. Home trials will also allow us to see what needs to be done to make our inventions work even better.
One Solid Ankle Cushion Heel (SACH) and two Dynamic Elastic Response (DER) prosthetic feet will be tried six times in random order by the patient. The patient will be an active prosthetic foot user who walks several kilometers per day and was amputated at the trans-tibial level because of injury. Gait pattern will be rated in comparison with the patient's previous prosthetic foot by a physiatrist, physiotherapist, prosthetist and the patient. One-leg standing and 10-meter walking tests will also be performed.
The goals of this study are to provide sensory information to amputees and reduce phantom limb pain via electrical stimulation of the lumbar spinal cord and spinal nerves. The spinal nerves convey sensory information from peripheral nerves to higher order centers in the brain. These structures still remain intact after amputation and electrical stimulation of the dorsal spinal nerves in individuals with intact limbs and amputees has been demonstrated to generate paresthetic sensory percepts referred to portions of the distal limb. Further, there is recent evidence that careful modulation of stimulation parameters can convert paresthetic sensations to more naturalistic ones when stimulating peripheral nerves in amputees. However, it is currently unclear whether it is possible to achieve this same conversion when stimulating the spinal nerves, and if those naturalistic sensations can have positive effects on phantom limb pain. As a first step towards those goals, in this study, the investigators will quantify the sensations generated by electrical stimulation of the spinal nerves, study the relationship between stimulation parameters and the quality of those sensations, measure changes in control of a prosthesis with sensory stimulation, and quantify the effects of that stimulation on the perception of the phantom limb and any associated pain.
The purpose of this study is to demonstrate the efficacy of functional electrical stimulation (FES) for trans-tibial amputees. The investigators aim to demonstrate that providing three months of FES intervention will increase knee extension strength, increase volume of the residual limb and decrease chronic and phantom pain.
The goal of this research is to determine the effectiveness of a powered prosthesis compared to an unpowered prosthesis during short bouts of walking, extended periods of walking (to fatigue), and performance in the community.
The aims of this study address an exploratory endpoint in the Major Extremity Trauma Research Consortium (METRC) Transtibial Amputation Outcomes Study (TAOS; NCT01821976) that is investigating prosthesis fit, alignment and condition of the residual limb. As there are no validated measures of fit and alignment (factors known to impact comfort, function and performance among amputees) the TAOS study includes a provision in the protocol for acquisition of photographs, video and radiographs in order to help develop uniform assessments of the residual limb. The goal of the ProFit study is to validate and refine the prosthetic assessment tool (ProFit) that was developed by an expert panel of certified orthotist prosthetistis (CPOs) in collaboration with orthopaedic trauma investigators, a measurement scientist and a biomedical engineer from the BADER consortium.
