Filter by:The goal of this clinical trial is to investigate the repeatability of application of a fully remote method of manufacturing 3D printing of prosthetic sockets for transtibial amputees, and determine user satisfaction of sockets produced through these methods. The study also aims to evaluate the time and cost effectiveness of this production model. The main question[s] it aims to answer are: 1. To determine the repeatability and user satisfaction with transtibial sockets produced using a remote-digital method as compared to conventional manufacturing methods. 2. To determine if transtibial prosthetic users have greater prosthetic satisfaction scores across the 4 Prosthesis Evaluation Questionnaire (PEQ) subscales of Utility (UT), Appearance (AP), Sounds (SO) and Residual Limb Health (RL) with the 3D printed socket fabricated through the remote-digital method compared to the laminate socket made using the conventional method. 3. To determine if transtibial prosthetic users experience greater socket comfort with the 3D printed socket compared to the laminate socket. Participants will receive a 3D printed socket (trial intervention) and a laminate socket (control intervention) and will use each socket for a period of 4 weeks.The order of socket use will be randomised. At the end of each 4 week period, participants will rate their comfort and satisfaction with the socket. At the end of the trial, participants will indicate their preferred socket, which will be fitted to their prosthesis. Participants will attend 6 visits across a total duration of 11 weeks during the course of the study.
The goal of this multicenter interventional pilot is to verify the functionality of a prosthesis for trans-femoral amputees. The main question it aims to answer are: - Is to verify the technical functionality, safety and reliability of the propulsive lower limb prosthesis prototype, with active ankle, so as to provide indications regarding the technical and functional developments to be implemented in the finalization of the device. - Provide an indication of the functional effectiveness of the device and its satisfaction by patients. Participants will perform: - walking tests inside parallel bars on flat and/or inclined terrain; - walking tests on treadmill; - stair climbing/descent tests.
If a person has to have a part of their body amputated, in this case their hand, the patient then lacks information about the missing limb, which in many cases leads to pain that severely restricts their quality of life and participation in everyday life. This is usually phantom and/or neuroma pain. Phantom pain is usually caused by many different mechanisms and occurs in 80-90% of patients. Pain caused by terminal neuromas affects 13-32% of amputees and manifests itself as residual limb pain. A neuroma itself is a benign lump that can develop at the site of the defect after a nerve has been severed (neurectomy). In some cases the impairment is so severe that prosthetic tolerance, functional independence and quality of life can be severely affected. Numerous treatment options for these types of pain are far from satisfactory for many patients and remain a major challenge for both the clinician and the person affected. It is often no longer possible for the patients to pursue a profession or hobby due to the pain as well as due to the pain medication required and its possible side effects. Surgical intervention can therefore be considered for patients who do not (or no longer) respond to conservative pain treatment. In recent years, many surgical approaches have been introduced to treat or prevent post-amputee pain. One of these methods can make it possible to create an authentic feeling of the missing limb and thus reduce or eliminate phantom pain by means of targeted sensory reinnervation (TSR) of the lost body part. Sensory reinnervation means that a nerve which enables a (sensory) perception associated with a sense is "redirected" to a new area of the body and can therefore fulfil at least part of its task again. In this case, an authentic feeling of the lost body part. The aim of this retrospective data-analysis is to evaluate data from patients with hand amputation (planned surgery or caused by accident/infection..) who have undergone TSR surgery to treat or prevent phantom and neuro-pain with regard to different parameters.

The goal of this retrospective questionnaire study is to evaluate the cost-effectiveness of non-microprocessor controlled prosthetic knees (NMPK) versus microprocessor controlled prosthetic knees (MPK) in persons with a knee-disarticulation or transfemoral amputation. The main aims are: - to provide an overview of the costs, health-related quality of life, and user experiences associated with the use of different types of prosthetic knees. - to evaluate the cost-effectiveness of the NMPK compared to the MPK for adult prosthesis users. Participants will fill out three questionnaires about (1) their medical consumption and productivity costs; (2) health-related quality of life; (3) utility, ambulation and well-being. Researchers will compare the persons with a NMPK to the persons with an MPK to investigate the cost-efficiency of both types of knees.
The goal of this observational study is to learn about the association between cardiac valve calcification and the 1-year mortality after lower-extremity amputation in diabetic patients. Diabetic patients requiring lower-extremity amputation were retrospectively studied. Preoperative detailed anamnesis was taken. Cardiac valve calcification was assessed using echocardiography at baseline. One-year follow-up was conducted and included clinical visits, hospital record assessment, and telephone reviews to obtain the survival status of patients. Researchers compare the survival group to the mortality group to study the relationship between the cardiac valve calcification and mortality.
Researchers aim to compare demographic characteristics, prosthesis type, functional capacity, and quality of life between faller and non-faller transtibial amputees.
Purpose of this study was to assess the balance level of highly qualified amputee football players in relation to their sports level, training experience, position on the pitch, as well as the type of amputation/dysfunction and disability experience.
The study will determine if Symphonie Aqua Digital System, a new method of socket creation, in a weight-bearing environment, may produce more successful fitting and comfortability & functional outcomes than traditional sockets (non-weight bearing scanning). Additionally, the study will determine if a well-fitting socket will positively impact the overall health of amputee residual limb.
The goal of this clinical trial is to determine the validity and reliability of the Community Integration Questionnaire-Revised (CIQ-R) scale in lower limb amputees. The main questions it aims to answer are: - The Turkish version of the Community Integration Questionnaire-Revised is valid for lower extremity amputees. - The Turkish version of the Community Integration Questionnaire-Revised is reliable for lower extremity amputees. Participants will: • Fill out general information, CIQ-R, TAPES, and ABIS forms.
