Filter by:The aim of the current study is to examine the biomechanical changes of gait kinetics in patients with either partial foot amputation or peripheral neuropathy
Through this pilot prospective trial, we aim to obtain preliminary data investigating the effectiveness of perineural catheters and liposomal bupivacaine, both currently accepted as standard care at Maine Medical Center, for the management of post-limb amputation pain. We will use the data that we collect to inform the design of a larger, appropriately powered study.
The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by nonbreathable and non-thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to passively conduct heat from the skin using thermally conductive elastomers. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.
This study explored the pattern and type of amputations performed on patients with diabetic foot who were admitted to our institution, as well as the 7-year mortality rate of patients with diabetic foot at the same institution. We believe that our study makes a significant contribution to the literature because it highlights the need for strengthening efforts to decrease the risk of amputation and mortality among patients with diabetic foot, especially in Jeddah, Saudi Arabia.
Veterans with dysvascular lower limb amputation (LLA) have a high fall risk, which persists despite completion of conventional rehabilitation. The presence of fall risk could be a primary reason for the high disability and low quality of life outcomes in this Veteran population. A potential novel intervention for this population is to train performance of tasks that require both physical and cognitive attention (i.e., dual-tasking). Therefore, the purpose of this study is to explore relationships between dual-task performance and self-reported falls for Veterans with dysvascular LLA. Further, dual-tasking occurs during everyday life and this project will examine the association between dual-task performance and participation in activities of daily living (basic and instrumental). The results will form the foundation for development and future study of a novel dual-task training program for Veterans with dysvascular LLA.
this project seeks to understand and quantify the effects of powered transtibial prostheses on socket loading and direct measures of residual limb health so as to inform the optimization of prosthesis fit.
A simple weight-bearing exercise has been designed using off-the-shelves devices (Nintendo Wii Balance Board) and centre of pressure (COP) analysis software (Python) for trans-tibial amputees receiving their first prosthesis. A pilot randomised control study will be conducted to check the progress with weight-bearing training using COP-based objective measures. Additionally, gait and functional task performance will be assessed by means of clinical test. Participants will be divided into 2 groups: test group (performing additional weight-bearing exercises) and control group (receiving only conventional training for fitting of initial prosthesis).
People with limb loss receiving inpatient rehabilitation are at greater risk for depression and anxiety, social isolation, and generally have poor quality of life. To proactively address the mental health needs of this population, this study plans to test an innovative psychological group therapy program designed for limb loss inpatients to enhance coping skills, address mental health challenges, and better prepare them to integrate back into the community via a randomized blinded feasibility trial. Since this is a novel intervention, adapted specifically for limb loss, this study will test the feasibility of delivering this inpatient group program to these at-risk individuals to see: if they will participate in the program, what they like/do not like about it, and if there are some early findings suggesting it is effective. Researchers will use these results to improve the psychosocial group program and to further test its effectiveness in a larger clinical study.
Diabetic foot ulcers (DFU) are one of the complications of diabetes mellitus resulting from multiple causes such as neuropathy, ischemia, and infection that contribute to morbidity and amputation. The prevalence of DFU has been estimated to be 3 to 5 times higher than the overall population. Minor amputations (digital or transmetatarsal) are the treatment of choice in case of irreversible DFU. However, many minor amputations do not heal and require re-amputation. Improvements of healing rate after adipose stem cells (ASCs) injection through micro-fragmented autologous adipose tissue of the amputation stump following minor DFU amputation were demonstrated. The use of ASCs obtained from the superficial enhanced fluid fat injection technique (SEFFICARE) to improve the healing process after DFUs minor amputation is the object of the present study. A single-center non-randomized prospective observational study will be performed. The recruited patients will undergo local injection of superficial enhanced fluid fat after a lower limb minor amputation. Laboratory analysis to evaluate the composition of the tissue and stromal cell components harvested from adipose tissue with SEFFICARE system by using digital droplets PCR. These data will serve for making associations between the clinical outcome and characteristics of the cell population administered to each patient.
This study is conducted to evaluate the efficacy of the Power Knee Mainstream Dynamic compared to passive microprocessor-controlled knees (MPKs) regarding metabolic cost for high active transfemoral amputees.The test is of a single group repeated measures crossover design. The primary endpoint is the difference in MET/HRI-VO2 index between conditions. Subjects are measured on their prescribed device at visit 1, be fitted to the PKM which they wear as their primary prosthesis for one week before coming for visit 2 and being measured again on the PKM.
