Filter by: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 device, a bipolar percutaneous intramuscular electromyography electrode, is intended for use in upper-limb amputation patients who have received the regenerative peripheral nerve interface surgical procedure, in order to enable the use of advanced prosthetic arms and hands.
The purpose of this study is to learn more information about nerves. This study is also designed to learn how the information in nerves could be used to develop new prosthetic devices.
AIM: To provide initial information on the efficacy (pain reduction) and safety of focused ultrasound surgery for the ablation of stump neuromas in amputees with chronic neuropathic pain. PARTICIPANTS: The study will include 10 amputees (men/women age >18 years old) with chronic (>3 months) phantom/residual limb pain (NPS ≥ 4). DESIGN: Patients potentially qualifying for the study will be offered an Informed Consent to sign prior to further evaluation. Those who accept will sign the informed consent, complete study questionnaires and be evaluated in terms of inclusion/exclusion criteria. Specifically, a complete medical history will be obtained to determine the patient's general health status, current symptoms, frequency and dosage of their current analgesic intake etc. Baseline pain scores will be established. If not performed within six months prior to the evaluation, a contrast MRI of the stump will be performed. Patients not meeting the study criteria will be exited from the study as screen failures and not be included in analyses. All qualifying patients will complete a baseline MRI exam on treatment day. Any patient not meeting study criteria at Imaging will be exited as screen failures. After completion of the MRI exam, qualifying patients will proceed to the ExAblate treatment. These patients will then be followed for 6-months post-ExAblate treatment; the patients will complete study follow-up questionnaires at 1, 3 days, 1 and 2 weeks, and 1, 3 and 6 months after treatments. Follow-up visits will take place 1 week and 1, 3 and 6 months after treatment to assess their pain status, their quality of life and safety. Data regarding dosage and frequency of analgesic intake for the management of post amputation NP will be collected. Relevant cost data will be collected in order to enable an assessment of the total cost of the procedure.
The purpose of this study is to evaluate how well subjects heal after surgery who receive standard dressings or incisional negative pressure wound therapy for non-traumatic amputation sites.
The purpose of this study is to determine whether the geriatric prosthetic foot 1M10 is superior to the classical SACH (Solid Ankle Cushion Heel) foot, when used by indoor ambulators with a transtibial amputation.
This is a 4-year, non-randomized, single center, patient self-controlled, clinical trial (though enrolled subjects will be followed for life as are all transplant patients) for patients seeking allotransplantation of the male external genitalia (MEG), or penile tissue, as a feasible reconstructive strategy for the treatment of devastating and irreversible injuries to the genitalia. In addition to receiving penile allotransplantation and post-operative monitoring and support, enrolled patients will receive an innovative and clinically proven immunomodulatory protocol that combines lymphocyte depletion of the recipient with donor bone marrow cell infusion. Patients will be treated with lymphocyte depleting induction therapy, donor bone marrow cell infusion and tacrolimus. After the first year, maintenance immunosuppression will be modified gradually and cautiously (tapered dose reduction or spaced frequency dosing of tacrolimus) in selected patients based on a critical evaluation of clinical and immunologic outcomes. Outcomes will include but not be limited to functional metrics (sensation, erection, voiding), psychosocial (body integrity, adaptation to transplant) and health related quality of life (HRQOL) measures.
Peripheral artery disease (PAD) affects 8-18 million in the US and is an economic burden, currently estimated to be greater than cancer and heart disease. Older age (> 65 years), smoking, diabetes and kidney diseases are some risk factors associated with PAD and are known to have increased morbidity and mortality.Early detection is critical for mitigating PAD progression. Ankle-brachial index (ABI) testing is recommended by the US Preventative Services Task Force as an affordable and effective screening tool for evaluating PAD risk. QuantaFlo™ (Semler Scientific, Inc.) is a novel, noninvasive, 510K FDA approved digital device that is used as a screening tool to measure ABI of patients at risk of PAD. This single center prospective clinical trial will evaluate the sensitivity and specificity of digital ABI in detecting PAD using color Doppler ultrasound and 'gold standard' angiography as reference. Specifically in patient undergoing dialysis and who cannot undergo ABI using pressure cuffs dialysis grafts/ fistulae in the arms, we will evaluate the value of digital ABI in detecting PAD.
The aim of this study is to assess the efficacy of the mirror therapy on phantom pain for patients with amputation after vascular etiology. the secondary aim are to measure the impact of the mirror therapy on quality of life, sleep disorders, and predictive factors for effectiveness. the design is a prospective study, randomised, blindly evaluated, monocentric. There will be 2 groups: 1) rehabilitation and gabapentine; 2) rehabilitation and gabapentine + mirror therapy during the first 4 weeks. The assessment are going to be preformed at the inclusion day and then every 2 weeks during 8 weeks. the primary evaluation criterion will be the phantom pain measured on a VAS. the delay for inclusion is 18 months in order ton include 40 patients. The length of the study is 20 months.
To assess the functional characteristics and utility of upper and lower limb prosthetic devices (advanced bionic and current clinical standard-of-care) that incorporate physiologically relevant touch and/or movement feedback.
