Filter by:The purpose of this study is to investigate the relationship between thigh strength and walking ability and assess if using a blood pressure cuff on the leg improves strength and walking performance.
The aim of this study was to investigate MIC and non-MIC prostheses in terms of gait pattern and energy consumption in above-the-knee amputee patients.
Amputation is the loss or removal of a body part such as an arm or leg. It is the last option in trauma treatment and irreversible procedure. Amputation rehabilitation begins in the pre-amputation period. The goal of rehabilitation after an amputation is to help the patient return to the highest level of function and independence possible, while improving the overall quality of life. Many factors can affect the success of lower limb amputation rehabilitation, and stump length is one of them. A sufficient stump length provides a large contact surface and increases the stability of the socket unit.
The finger and fingertip are the most frequently amputated body parts, due to work-related incidents. Yet because of space, weight and cost constraints, prosthetic fingers and fingertips are heavy and bulky with limited active motion and sensation. Most are basic variations on the hook and claw. Lower limb prostheses have become extremely technologically advanced in their design and materials, and upper limbs lag behind in all of these areas. This is due to the complexity of the anatomy and function of the upper limb compared to the lower. There are no commercially available prostheses that offers direct sensory feedback and as such, rely on visual feedback from the wearer. The original PROLIMB study (PROLIMB I) used a Leap Motion Controller (LMC) to investigate the type of grasp adaptation that have been undertaken by patients during the rehabilitation process following amputation and compared this to similar data from healthy volunteers. PROLIMB I also looked at refining the tactile feedback system by investigating the sensation felt on amputation sites in order to feed this information into the haptic feedback system. The vision of the PROLIMB II project is to build on the work completed in PROLIMB I and develop and combine mechanistic models of hand motion and haptic sensing to deliver novel, affordable body-powered prosthetic fingertip digits with enhanced motion and sensation to address current clinical needs and support the quality of life of amputees. With collaboration from the University of Warwick (UoW) and University College London (UCL), Steeper Group and Naked Prosthetics the PROLIMB II study will aim to model, design, fabricate and validate a body-powered prosthetic fingertip digit with integrated sensory feedback. The University Hospital Coventry & Warwickshire (UHCW) will provide the clinical facility with which to assess the comfort, usability and acceptance of this prosthetic in the daily lives of patients with digit amputations. This project will be a proof of concept study with verification of the prosthetic in motion capture (gait) laboratories as well as the use of simple validation data collection over a longer period.
Amputation is a problem that can be encountered for many reasons, can cause functional disability in varying severities and puts a multifaceted financial burden on individuals, society, and states. The phantom feeling is the state of the sensory sensation of a limb that does not already exist and is observed in various forms in individuals with amputation. The aim of this project is to investigate whether the phantom sensation affects autocorrelation of gait in unilateral amputated individuals and thus to determine whether the phantom sensation is a functional sensation that affects the multifaceted nature of gait. In addition, the measurement of whether phantom sensation contributes to the ability of amputees to adapt to changing conditions and obtaining a unique calculation method that determines autocorrelation are other specific aspects of the study. The study will be conducted on individuals with unilateral traumatic transtibial amputation who have acceptable phantom sensation, individuals with no-phantom sensation and healthy individuals. Individuals who meet the inclusion criteria will be included in the gait assessment. During the evaluation, at least 512 consecutive steps will be collected from each individual when walking on the treadmill at their preferred speed. The walk test will then be repeated on the perturbation treadmill of 5-10%. It will be determined whether the gait characteristics obtained by gait analysis show autocorrelation by using signal processing methods.
Microvascular partial toe transfer for reconstruction of traumatic amputation of the digits
Twenty individuals who were referred to receive physiotherapy will be participants of the study. Participants with lower limb loss will evaluate with the following assessment tools: Demographic datas; age, gender, height, body mass, year, side and level of limb loss will be recorded. Gait parameters (step length, variation of step length) will evaluate with Gait Trainer Biodex 2, at participant's preferred speed.Phantom sensation and phantom pain will be asked as existence or not. Sensorial loss will evaluate with Semmes Weinstein Monofilaments
