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.
The objective of this study is to develop a feasible and safe regimen for minimization of immune suppression in recipients of vascularized composite allotransplants (VCA) using a daily dose of recombinant IL-2. In order to achieve this aim, this trial will: 1. Perform VCA in 5 eligible subjects; 2. Administer recombinant IL-2 at a low-dose to promote the expansion and function of regulatory T cells in subjects who received VCA; and 3. Minimize immune suppression to tacrolimus single therapy in subjects who received VCA and recombinant IL-2. This trial will also investigate if it is possible to predict immune rejection in VCA using blood and tissue samples from recipients of VCA. Lastly, this trial will develop non-invasive technologies to monitor for VCA rejection. These technologies will involve magnetic resonance imaging. Multi-contrast ultra-high resolution MR imaging (MRI) with serial direct planimetry will be performed in recipients of VCA.
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.
Our goal is to temporarily implant the following groups for 540 +/- 30 days: 1. Forearm FAST electrodes 1. Five human partial hand amputees (amputated at the level of the hand) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve. 2. Five human hand and forearm amputees (amputated at the level of the forearm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve . 2. Arm FAST electrodes 1. Five human partial hand amputees (amputated at the level of the hand) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve. 2. Five human hand and forearm amputees (amputated at the level of the forearm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve. 3. Five human hand, forearm and arm amputees (amputated at the level of the arm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve.
The primary purpose of this study is to determine the extent to which the Regenerative Peripheral Nerve Interface ( i.e. reinnervation of partial muscle grafts by residual peripheral nerves) enables both the generation of high-performance motor control signals for prosthetic limbs, and the input of sensory percepts by electrical stimulation.
Twenty individuals who were referred to receive physiotherapy will be participants of the study. Participants with lower limb loss will evaluate with the following assessment tools: Demographic datas; age, gender, height, body mass, year, side and level of limb loss will be recorded. Gait parameters (step length, variation of step length) will evaluate with Gait Trainer Biodex 2, at participant's preferred speed.Phantom sensation and phantom pain will be asked as existence or not. Sensorial loss will evaluate with Semmes Weinstein Monofilaments
