The proposed study aims to characterize the effects of running-specific leg prosthetic stiffness and height during on performance during running and sprinting to optimize running-specific prosthesis prescription. The investigators will collect biomechanical and metabolic data from participants with unilateral and bilateral below the knee amputations while they run at different speeds on a treadmill. This data will be used to understand the effects of running prostheses. Then, these parameters will be used to develop prosthetic prescription techniques for people with below the knee amputations.
The Southern Illinois University (SIU) Hand Transplant Program is a multidisciplinary research effort with the goal of restoring form and function to unilateral or bilateral upper extremity amputees by vascularized composite allotransplantation of the hand/upper extremity (hand transplantation). Hand transplantation includes transferring upper extremities/hands from deceased human donors to patients with single or bilateral hand or arm amputation. The purpose of the trial is to study functional, psychological, and immunological outcomes of human upper extremity allotransplantation.
This study will evaluate the feasibility of using implanted myoelectric sensors (IMES) to control an electromechanical prosthetic wrist and hand.
The proposed study aims to characterize biological ankle joint function during walking and running on slopes in order to further develop advanced powered ankle-foot prostheses. Ankle joint torque and angle data will be collected from non-amputees while walking and running at multiple speeds and slopes. This data will be used to develop control parameters for a powered ankle-foot prosthesis. Then, these parameters will be implemented and tested in a powered prosthesis worn by people with below the knee amputations.
The prospective cohort study, SuTra2, assesses the functional and socio-economic status of patients who were operated on for a severe limb injury resulting in amputation or limb preservation 1 and 2 years after the 2010 Haiti earthquake.
Amputees often choose not to wear prostheses due to marginal performance or may settle for a prosthesis that offers only cosmetic improvement, but lacks function. A simulation tool consisting of a robotics-based human body model (RHBM) to predict functional motions, and integrated modules for aid in prescription, training, comparative study, and determination of design parameters of upper extremity prostheses will be developed. The main objective of collecting and analyzing human movement during several common tasks is to optimize and validate the robotics based human model. The range of motion data of subjects performing activities of daily living such as opening a door, turning a wheel, grooming, eating, bilateral lifting, as well as recreational and sport activities such as swinging a baseball bat, and golf club will be analyzed. This motion analysis data will also be used to compare data between four groups: a control group (n=10), a braced group simulating prosthesis use (n=10), a group wearing a transradial prosthesis (n=10) and a group wearing a transhumeral prosthesis (n =10).
The overall study objective is to examine the feasibility, acceptance, and benefits of home use of an advanced upper limb prosthetic device as well as the logistical support requirements utilized during 3 months of home usage. All participating subjects will enroll in Part A of the study which will involve supervised training. Eligible subjects will be invited to participate in Part B, the home use portion of the study.
The purpose of this pilot study was to conduct a head-to-head comparison of two designs for transhumeral level upper limb prosthetic sockets: a traditional socket design and a socket design hypothesized to provide greater skeletal stabilization. The investigators comparisons included assessments of patient comfort and satisfaction with fit, as well as dynamic kinematic assessment using X-Ray Reconstruction of Moving Morphology (XROMM) a novel high-speed, high-resolution, bi-plane video radiography system.
In older adults, poor circulation in the lower extremities leads to serious health complications including limb loss. In addition, individuals with dysvascular disease also suffer from other co-morbidities like diabetes, coronary and cerebrovascular disease. An individual with a transfemoral (TF) amputation is usually fitted with a prosthetic limb to assist with function, including a prosthetic knee and a prosthetic foot. Currently, dysvascular amputees are given a prosthetic knee based on the basic expectation that they will be functionally stable. This consideration does not address higher levels of function like walking at multiple speeds and over uneven ground. Also, dysvascular amputees are not able to counteract their co-morbidities with a more active lifestyle. Walking is less energy efficient; their traditional prostheses may cause early onset of fatigue and induce a fear of falling. Newer microprocessor knees enable patients with transfemoral amputations to walk on different surfaces and at multiple cadences through better control in swing and stance phases of gait. The impact of the functional differences in the prostheses is not clear and requires additional investigation to clarify the choice of the most appropriate functional prosthesis. The purpose of this study is to compare the functional outcomes with the traditional mechanical knee versus the microprocessor knee (C-leg) in transfemoral amputees.
