Filter by: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 double amputation of the forearms is a rare handicap that seriously impacts the autonomy and the quality of life of patients, social and familial exclusion, and dependence on third parties for everyday activities. The management of these patients is nearly exclusively through the use of prostheses. Certain patients refuse this solution, or remain penalized by the absence of sensitivity , the lack of precision in movements, and body image issues related to the amputation; the double graft of hands and forearms may, in this circumstance, be the only solution. Since January 2000, date of the first double hand graft, six bilateral grafts of hands have been performed at the Hospices Civils de Lyon. This first study reported the feasibility of the graft. The functional results obtained after the double transplant have allowed patients to recover complete autonomy for everyday activities, at the price of an immunosuppressive treatment. We have found that these very good functional results are maintained over time and, for a certain number of patients, to return to work which is a factor of social integration. The rate of medical complications (metabolic, infectious, oncological), essentially related to the immunosuppressive treatment, is not greater to that found for other types of graft, but are considered as a limiting factor for the development of this strategy. These results are confirmed by international experience that is of the same order. Only a few rare cases of re-amputation have been reported in patients for whom the immunosuppressive treatment was discontinued or following vascular thrombosis. A new study is required to continue this evaluation and to compare double graft to prostheses in terms costs, quality of life, usefulness, satisfaction, autonomy, and social integration. The results of this study will allow the placement of these strategies in the management of patients with double amputation of the hands and forearms.
The purpose of this study is to determine the effect of prolonged effort in long distance running on the biomechanical bilateral asymmetry in the lower limbs of trans tibial amputee running with running specific prosthesis.
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.
Direct Skeletal Fixation of Prosthetic Limbs Following Trans-Femoral Amputation - Study of an Intraosseous Transcutaneous Amputation Prosthesis (ITAPTM).
This is a two-site study that explores the effects of mirror therapy and transcranial Direct Current Stimulation (tDCS, Soterix ©) in a randomized factorial controlled trial in which patients will be assigned to one of four groups: active tDCS and active MT; sham tDCS and active MT; active tDCS and sham MT (which consists of using a covered mirror for the therapy); and both sham tDCS and sham MT (covered mirror).
Fingertips facilitate smooth motor activity, precise sensation, and the delicate movement of the hands and have an aesthetic function. Fingertip injuries are defined as injuries occurring distal to the insertion of the flexor and extensor tendons. These injuries are one of the most common trauma injuries presented in acute care settings, accounting for approximately 4.8 million emergency department visits per year in the United States.(1) Fingertip amputations may not constitute the majority among these fingertip injuries but can have a complex spectrum of injury. In these cases, the reconstruction methodologies focus on preserving the digital length, ensuring adequate soft tissue coverage, preserving the nail structure, achieving a well-contoured and painless fingertip, and restoring durable and sensate skin. There are so many factor that influence the result of composite graft in distal finger tip amputation. Investigators will collected the data including the size of amputee , shape, level of amputation, mechanism of amputation, if hyperbaric oxygen therapy, operation procedures.
Injuries to the genitalia are of concern to the military with emphasis placed on the surgical reconstruction and psychological health of these Wounded Warriors. However, despite significant surgical advances in microvascular surgery and autologous free tissue transfer, conventional reconstructions cannot truly replace the complicated structures and functions of the penis including the urethra, erogenous sensation, and erectile corporal bodies. Conventional reconstruction poses several challenges: patients may not have sufficient donor tissue due to other injuries or previous surgery; multiple operations are often needed to restore the neophallus; the final reconstruction only approximates the penis' native form; recreating the urethra is challenging and the new urethra is prone to stricture and fistula formation; the erectile function necessary for sexual intercourse is often lacking; and insufficient protective sensation can lead to penile implant extrusion, infection, subsequent explantation or loss of the reconstruction. The investigators propose this clinical trial to determine functional outcomes and quality of life for Wounded Warriors and civilians who choose to undergo penile allotransplantation. The investigators will combine extensive experience performing total penile reconstruction in a large population affected by congenital, traumatic, and therapeutically extirpated Genitourinary deformities and expertise in reconstructive transplantation using an immunomodulatory protocol to for this study. The investigators anticipate penile transplantation can potentially replace "like with like," restoring the appearance, anatomy, and function of the recipient in a manner far superior to autologous reconstruction. This project will establish the ability to perform penile allotransplantation using an immunomodulatory protocol and will compare outcomes with conventional phalloplasty patient results. Study Design: This is a non-randomized subject self-controlled clinical trial to implement a cell-based immunomodulatory protocol for penile allotransplantation. An intermediate deliverable is achieving allograft survival and functional return with reduced dosing/frequency of maintenance immunosuppression on steroid-free monotherapy (tacrolimus) immunosuppression. The long-term deliverable and goal is to demonstrate superior outcomes when compared to satisfaction and QOL in conventional phalloplasty patients 12-60 months post-transplant.
The purpose of this study is to improve prosthesis control for transradial amputees with combining targeted muscle reinnervation surgery (TMR) and pattern recognition control.
