A metabolically efficient leg brace
Locomotion assistive devices can be broadly classified as either being passive or powered. Both have been created to aid in the leg's generation of a ground reaction force which supports the torso during locomotion, yet their inherent design has limited their functional growth to date. While many …

A Comparison of Predicted Brace Loads in Temporary Retaining Structures and Observed Brace Loads in Two Full Scale Test Sections
… culvert was constructed within a sheeted and braced excavation. Information provided by Eustis Engineering Company to the USACE is presented describing the existing soil conditions, the construction schedule, the geotechnical testing apparatus and instrumentation, and the data produced from …

A knee brace design to reduce the energy consumption of walking
Recent research into the mechanics of walking indicates that a quasi passive wearable device could be created which dramatically reduces the metabolic energy used in walking especially when the wearer is carrying additional torso weight. Target population groups include military personnel who must …

Design of a hand-held user interface for the active joint brace
The continued development of the Active Joint Brace, a powered orthosis, required that a suitable user interface be designed to control the brace. Since the brace is an electronically-controlled mechanical, medical device, it was important that the user interface (UI) provide both a proper …

Performance evaluation of innovative toggle brace damper for flexible structure seismic upgrade
… the seismic performance evaluation of the toggle brace frame configuration employed for seismic upgrade. In order to carry out a performance evaluation of the toggle brace damper, a practical approach to performance-based earthquake engineering (PBEE) is presented in this study. The approach …

IMU-Integrated 'Smart' Knee Brace Validation Using Optoelectronic Motion Capture During Treadmill Walking
… to be valid in measuring joint angles. A ‘smart’ brace was implemented with two IMUs and the knee joint angles calculated using data from the ’smart’ brace were compared to a gold standard motion capture system to assess the agreement and reliability of the brace. Ten participants visited the lab …

Adolescent adherence to orthopedic brace wear: A behavioral assessment of high risk factors
… curves is that the adolescents may not wear the brace as prescribed or long enough for the brace to be effective. The present investigation used electronic monitoring and temperature probes to investigate whether the adolescents were wearing their brace during events identified using a modified …

Investigation of Inflection Points as Brace Points in Multi-Span Purlin Roof Systems
… to evaluate the behavior of inflection points as brace points in multi-span purlin roof systems. Seven tests were conducted using "C" and "Z" purlins attached to standing seam and through fastened panels. These tests were subjected to uniform gravity loading by means of a vacuum chamber. The …

Design, Validation, and Clinical Testing of a Novel Fastening Device for a Scoliosis Brace
… children in the US were put into a scoliosis brace. The primary function of scoliosis braces was to reduce and prevent progression of the spinal deformity as the patient grew by application of corrective forces to the spine. Straps, often made of Velcro, were attached to the back of the brace …

Brace Effectiveness of Cross-frame Layout and Connection Design on Skewed Steel Bridges During Construction
The Kansas Department of Transportation (KDOT)'s current design practice is to align cross-frames parallel to the skew angle to avoid problems associated with fit-up during erection. The American Association of State Highway and Transportation Officials (AASHTO) provisions for bridges with skew …

A clinical and biomechanical study of cast-brace treatment of fractures of the femoral shaft
This thesis reviews fracture treatment from early history to the beginning of the First World War; and treatment of fractures of the femoral shaft from then to the present day. A detailed review of the knowledge of fracture healing in relation to fractures of the femoral shaft is undertaken, with a …

Evaluation of force distribution within a dual special moment-resisting and special concentric-brace frame system
… Moment Resisting Frame-Special Concentric Brace Frame System (SMRF-SCBF) under three different force distributions. The three distributions were 80% - 20%, 75% - 25%, and 70% - 30% with the lesser force being allotted to the Special Moment Resisting Frame (SMRF) portion of the system. In …

A Comparison of Optimized Nonlinear Time History Analysis and the Equivalent Lateral Forces Method for Brace Design
… of a design procedure for buckling-restrained braced frames (BRBF's). This procedure uses nonlinear time history analysis and a formal optimization algorithm. The time history analysis includes an elasto-plastic model for the braces. The optimization algorithm is a genetic algorithm. This …

Scoliosis Analog Model for the Evaluation of Bracing Technology
<p>Thoracolumbar braces are commonly used to treat Adolescent Idiopathic Scoliosis (AIS). Braces serve to reduce and prevent progression of the spinal curve by applying corrective forces. The magnitude and direction of these corrective forces applied by the brace to the spine remain unknown. …

Strategies for using electromyographic signals to control ankle torque in an active joint brace for alleviating drop-foot gait
This thesis describes the efforts to develop control strategies that use EMG signals from the anterior tibialis muscle to control ankle torque in an active ankle-foot orthosis. This would ultimately help rehabilitate persons affected by drop-foot gait, a condition which results in the loss of …

Design and evaluation of a quasi-passive robotic knee brace : on the effects of parallel elasticity on human running
While the effects of series compliance on running biomechanics are documented, the effects of parallel compliance are known only for the simpler case of hopping. As many practical exoskeleton and orthosis designs act in parallel with the leg, it is desirable to understand the effects of such an …
