Diabetes affects 463 million population of the world. Diabetic foot is one of the complications of uncontrolled diabetes which can lead to amputation in 5- 24% of non-healing diabetic foot ulcers. Every 30 seconds a lower extremity is amputated in the world due to diabetes. This is a retrospective study conducted in Balochistan, Pakistan. In this study investigators explored the risk factor of amputation in diabetic patients. Baseline characteristics, clinical profile, and lab tests were retrieved retrospectively and presented in the forms of tables. Investigators compared the categorical variables in amputees vs non-amputees and analyzed associated risk factors of amputation.
This study evaluated the effect of joint position sense on compliance with the prosthesis, balance and functional performance in individuals with lower extremity amputation due to diabetic polyneuropathy. Study group consisted of 16 subjects with unilateral transtibial amputation due to diabetic polyneuropathy and control group consisted of 16 subjects with unilateral transtibial amputation due to traumatic reasons.
This work will focus on new algorithms for powered prostheses and testing these in human subject tests. Individuals with above knee amputation will walk with a robotic prosthesis and ambulate over terrain that simulates community ambulation. The investigators will compare the performance of the advanced algorithm with the robotic system that does not use an advanced algorithm.
Phantom limb pain (PLP) is defined as pain or discomfort in a missing limb following amputation, whereas residual limb pain (RLP) is often experienced as pain at the site of amputation. Unfortunately, PLP can affect as many as 80% of upper- or lower-extremity amputees, with 40-60% also experiencing RLP. There are many theories regarding the mechanisms underlying these types of pain, but effective treatments remain elusive .Amputation of a limb is often accompanied by a traumatic event that can be emotionally devastating. Consequently, studies have reported high levels of depression in this population, up to 80%. Other studies have reported elevated levels of depression (70%), suicidality (30%) and posttraumatic stress disorder (PTSD, 20%) with PTSD being highly correlated with PLP. Thus, it is critical that effective treatments be employed that address, not only the chronic pain, but the comorbid conditions as well. Diet interventions have been utilized as a non-pharmacological method to reduce pain and/or inflammation. We have shown that a low-carbohydrate diet (LCD) reduced pain independent of weight loss. Importantly, we observed a reduction in depressive symptomology and improved quality of life (QOL) following the LCD. Thus, it is reasonable to expect that the LCD may have beneficial effects of pain experience and also on measures of QOL. Phase 1: To characterize the dietary habits, pain severity and psychological well-being of the local amputee population. Hypotheses: We expect that the local population will show high prevalence of phantom limb pain (PLP) and/or residual limb pain (RLP). Self-report of depressive symptomology, poor-quality diet, will coincide with low QOL reports. Phase 2: To assess the feasibility and efficacy of a low-carbohydrate diet (LCD) to reduce pain and increase QOL in amputees. Hypotheses: All participants will complete the 6-week LCD. Compared to baseline, a 6-week LCD will reduce self-reports of pain and depressive symptoms. Overall QOL will improve over 6 weeks with concomitant improved mood and sleep.
Lower-limb amputation is associated with life-altering and life-limiting comorbidities. Currently, onus is on primary care providers to diagnose, educate, and refer patients for appropriate management. Recently our laboratory has found, however, that of adults post-amputation seen in an outpatient Limb Loss Clinic presenting with comorbidities, >50% are unaware they have signs of peripheral arterial disease and/or neuropathy. Lack of patient awareness and thus, inadequate comorbidity management, may contribute to suboptimal patient outcomes post-amputation. As a first step in this research line, the proposed project will help determine if comorbidity screening by prosthetists during routine care visits for patients post-amputation may enhance comorbidity awareness, increase patient satisfaction in prosthetic services, and reduce gratuitous prosthetic service utilization. During a follow-up visit, seventy patients following a unilateral lower-limb amputation will be randomized into either a standard-of-care group or a standard of-care plus group. The standard-of-care plus group will receive clinical screenings by a certified prosthetist for peripheral arterial disease, peripheral neuropathy, depression, and high-risk for persistent back pain; patient education on findings; and each participant's primary care provider will receive screening results. The long-term goal of this research is to determine if prosthetists can maximize their utility in an interdisciplinary care team, while enhancing patient outcomes post-amputation.
The study investigated the perceived-mobility of patients with unilateral lower limb amputations by means of patient-reported outcome measures (PROMs). Such aspect may play an important role in evaluating the patient impairment and addressing forensic-medical issues. However, to this concern, the use of PROMs has not been extensively investigated yet. Among the validated PROMs, the study assessed self-perceived mobility and quality of life by administering the Trinity Amputation Prosthetic Evaluation Survey (TAPES) and the more recent Prosthetic Mobility Questionnaire (PMQ). The aim of this observational study was to improve the estimation of the physical and psychological impairment caused by the amputation, focusing on the impact of the limb loss on social participation, quality of life and daily living activities.
Lower limb amputations account for more than 85% of all amputations. In Canada, it has been reported that transtibial amputation (TTA) is the most common level of amputation. Many people with limb amputation have awareness and feel that their missing limb still exists (phantom limb), with perceptions of sensation or pain, and the ability to move the limb with or without intention. Phantom limb sensation (PLS) is defined as all non-painful somatic sensations (e.g. sense of the limb position, touch, pressure, warmth or cold, or movement) in the missing part of the limb. The incidence of PLS is about 60% in adults after 17 months. In addition to PLS, 60-70% of people with amputation experience phantom limb pain (PLP), an intense chronic pain perception in their phantom limb, in the first year after amputation. Although PLP is well known to decrease the quality of life and lessen function, little is known about PLS and phantom limb control (PLC), the ability to intentionally move or control movements of the phantom limb. Enhancing PLS and PLC especially in the immediate months after amputation, could decrease painful perception, facilitate prosthetic control, and improve the function of people with amputations. Keeping this therapeutic and rehabilitative significance in mind, it is hypothesized that a targeted program of phantom motor execution, designed to address phantom limb awareness (PLA), the general knowledge of the presence or existence of the missing limb as one's own, could be associated with improving PLC in people with TTA. Furthermore, prosthetic embodiment, the sense that the prosthesis is accepted as a part of the body with the same functional abilities, may play a role in PLC. Investigating the association of PLC, as one of the phantom phenomena (i.e. PLA, PLS, PLP, and PLC), with surgical, clinical, and demographic characteristics of people with TTA will provide better insight into how phantom phenomena develop. The association of PLC with physical function has significant clinical importance that has never been investigated in people with TTA.
