Filter by:The aim of this study is to investigate the relationship of hip muscle thicknesses measured by ultrasonography with hip flexion and extension strength and clinical parameters in prosthesis users with unilateral traumatic transfemoral amputation.
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.
The purpose of this research study is to see how well a new type of myoelectric prosthesis works. A myoelectric prosthesis is a robotic limb for amputees that is controlled by sensing the activity of muscles in the body above the amputation level. This study involves a medical procedure to implant the Myoelectric Implantable Recording Array (MIRA) in the residual limb. The procedure will be performed under sedation by a physician. When muscles contract, they generate an electrical signal that can be sensed by MIRA and used to control the prosthetic limb. Myoelectric prosthetic limbs normally use electrodes that are placed on the surface of the skin to control different movements. However, MIRA is implanted under the skin, which could improve the ability to control the myoelectric prosthesis. After the MIRA is implanted, training will occur to learn how to control the prosthesis using the muscles in the residual limb. The device can stay implanted for up to one year. The device will be removed (explanted) by a physician.
The aim of this study is to compare the sitting and standing postural stability of transfemoral individuals with healthy individuals with similar demographic characteristics.
Glittre activities of daily living test is used in different populations. The test, which is valid and reliable in different populations, has not been validated in amputees. In our study, we wanted to investigate the validity and reliability of the Glittre activities of daily living test (Glittre ADL) test in amputees using a lower extremity prosthesis.
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.
A trial to compare the performance of the SoftHand Pro (SHP) and Ossur i-Limb in people with transradial limb loss over an 8-week period.
The aim of this study is to investigate the relationship between sagittal spinopelvic parameters and low back pain and quality of life in individuals with lower extremity amputation.
Investigators will test if changes in CO2 is detected postoperatively in ischemic tissue in a replanted extremity of a traumatically amputated upper or lower extremity. IscAlert is measuring continuously CO2 in muscular and subcutaneous tissue. IscAlert is inserted distal to the operative field into normal muscle and/or subcutaneous tissue in the replanted extremity. Local tissue CO2 and temperature will be monitored continuously postoperatively for the next 10 days. If a reduced or totally obstructed blood flow appear (thrombosis), an increase in tissue CO2 and a lower local temperature will emerge rapidly as a sign of ischemia. This will be detected by the sensor which will alarm the investigators. This will lead to assessment of the replanted extremity and if restricted blood flow is diagnosed, a reoperation will be performed. After reoperation new sensors will be implanted for another ten days if applicable. Sixty patients will be enrolled to undergo the procedures. The IscAlert will be removed from the patient before the patient is discharged from the hospital or a maximum of 10 days (the event that occurs first). 500 devices is planned to be used in this clinical study.
The goal of this proposed project is to gather community-based data from the K4-level Transfemoral Amputee (TFA) population to aid in evidence-based prescription of powered prosthetic knees (i.e., choosing the right device to maximize the benefit for each patient). The investigators envision that this Level 1 submission will transition into a larger follow-on Level 2 trial that will explore a larger spectrum of patient populations (K2-K4), as well as testing additional Power Knees currently in development that are expected to become commercialized in the near future. The investigators intend to use this Level 2 trial data to guide the implementation of effective prescriptions towards those that can benefit most from a given device and limit prescription to those who would not see benefit in order to ensure the most judicious use of Department of Defense (DoD) and Veteran's Affairs healthcare dollars. The findings will also be shared with the research community to help drive the design of future devices by identifying what features and functions are most beneficial to which patient populations when the devices are used outside of the laboratory. In summary, more community-based data on how powered prosthetic knees compare with MPKs is needed to allow for improved clinical decision making and clinical outcomes.
