Neuromechanical adaptations in joint stiffness when hopping with a SL-AFO
(Georgia Institute of Technology, 2007-04-11)Humans hopping on different elastic surfaces in series adjust leg stiffness to maintain system stiffness primarily by modulating ankle joint stiffness. When a parallel elastic element is applied at the ankle to assist ... -
Pedaling Asymmetry in Unilateral Transtibial Amputee Cyclists and the Effect of Prosthetic Foot Stiffness
(Georgia Institute of Technology, 2007-04-11)In addition to its rehabilitation potential, a prosthetic designed for cycling will enable amputees to have the benefits of cardiovascular exercise and participation in sports. A prosthetic design for cycling can be aided ... -
The Effect of Model Design, Cushion Construction, and Thin Pressure Mats on Pressure Measurement
(Georgia Institute of Technology, 2007-04-11)Wheelchair cushions are designed to protect skin by reducing and distributing pressure. Pressure sensors and buttock models are used in standardized testing of wheelchair cushions. The purpose of this study was to explore ... -
Stiffness properties of prosthetic feet under cross-slope conditions
(Georgia Institute of Technology, 2007-04-18)As an integral component after lower extremity amputation, prosthetic feet assist the body in forward progression, weight bearing stability and shock absorption. A Key element of weight bearing stability is the foot’s ... -
Asymmetric Stability Margin of Postural Response to Perturbation in Unilateral Transtibial Amputees
(Georgia Institute of Technology, 2007-04-18)Falling is an important clinical problem in amputee population. In unilateral transtibial amputees, increased postural sway in quiet standing and asymmetric EMG reactions in anticipatory postural adjustments to rapid arm ... -
The Capacity of the Prosthetic Profession to Provide Lower Extremity Prosthetic Limbs within the State of Georgia
(Georgia Institute of Technology, 2007-04-18)Due to an aging population and a rise in conditions known to increase the risk of amputation, demand for prosthetic services is thought to be increasing nation wide. 20% of certified practitioners will reach retirement age ... -
The Effect of Surface Curvature and a Gel Liner Interface on Performance Properties of the Tekscan Socket System
(Georgia Institute of Technology, 2007-04-25)The presence of mechanical loads at the limb socket interface is considered an initiating cause of tissue breakdown and ulceration. Historically, prosthetists have relied on past experience, patient feedback, and indirect ... -
Upper Extremity Robotic Therapy for Individuals with Spinal Cord Injury
(Georgia Institute of Technology, 2007-04-25)Cervical injury causes tetraplegia in about half of spinal cord injury (SCI) cases and results in impaired hand function. Despite their different etiologies, both SCI and stroke subjects have demonstrated recovery by similar ... -
A Method of Prototype Evaluation for Assistive Mobility in Animals: Intervention for a Congenitally Malformed Dog – a Case Study
(Georgia Institute of Technology, 2007-04-25)Several studies report successful fittings of tripedal quadruped animals with prosthetic devices, but very few report fittings of bipedal quadrupeds. None of these studies report how the animals were trained to use their ... -
Testing the Skin Interrogation Device
(Georgia Institute of Technology, 2008-04-09)The purpose of this project was to perform a series of bench tests to evaluate particular aspects the Skin Interrogation Device (SID), a prototype instrument designed to measure the in-vivo mechanical properties of human ... -
Kinematic Effects of Sloped Surfaces on Shank Angle for Persons with Drop Foot
(Georgia Institute of Technology, 2008-04-09)Functional Electrical Stimulation (FES) was introduced in 1961 by Liberson as an alternative to the Ankle Foot Orthosis (AFO) for treating drop foot. The common peroneal nerve can be stimulated to create dorsiflexion in ... -
Evaluation of Alignment Methods for Transtibial Prostheses
(Georgia Institute of Technology, 2008-04-16)There are an estimated 3-4 million amputees in need of a prosthesis in developing countries. These people are unlikely to receive prosthetic limbs due to remote living conditions, finances, and few providers of care. The ... -
Lower Limb Joint Forces in Transtibial Amputees during Cycling
(Georgia Institute of Technology, 2008-04-16) -
Frontal Plane Characteristics of Multi-Axis Feet: A Test Method for Evaluation and Effect of Shoes on Foot Performance
(Georgia Institute of Technology, 2008-04-23)Introduction: The purpose of this project is to analyze the stiffness properties of multiaxis prosthetic feet in the frontal plane, and analyze the influence on mechanical testing of those feet when a shoe is worn. We ... -
Natural Progression of Non-Synostotic Plagiocephaly
(Georgia Institute of Technology, 2008-04-23)Background. Despite having a good understanding of the causes and treatment for deformational plagiocephaly, the need for treatment has yet to be determined conclusively. The purpose of this study was to determine the ... -
The Effect Of Prosthesis Suspension On Residual Limb Pistoning
(Georgia Institute of Technology, 2008-04-23)The main goal of transtibial prosthesis suspension is to minimize residual limb motion within the prosthesis. Poor suspension can lead to negative outcomes in prosthetic treatment, and may have a great impact on the ... -
An Association Between Translation and Hand Dominance
(Georgia Institute of Technology, 2009-04-08)Many tests are available for measuring and evaluating hand function. These tests measure manual dexterity, requiring arm-hand coordination and using the hand as a unit. Translation, a task requiring moving an object from ... -
Clinical Reliability of a Device for Measuring Forces and Moments in Amputee Gait
(Georgia Institute of Technology, 2009-04-08)Practitioners find it difficult to measure forces and moments on a prosthesis when an amputee walks. Traditional measures, such as using force platforms, are expensive and inaccessible. Practitioners also question the ... -
