Lower extremity features of Velocardiofacial syndrome and other 22q11 deletions
This study investigated the symptom of recurrent leg pain of unknown aetiology (PUA) in children and adolescents with 22q11 deletion. A leg pain questionnaire was designed and administered to 300 patients with 22q11 deletion and to 4507 school children. Replies were received from 119 patients …

Lower extremity amputation in people with diabetes: Trends and determinants
… Assessing quality of diabetes care is difficult. Lower Extremity Amputation (LEA) is recognised as a marker of the quality of diabetes care. The focus of this thesis was first to describe the trends in LEA rates in people with and without diabetes in the Republic of Ireland (RoI) in recent years …

Long term mortality after lower extremity amputation in South Africa
Introduction: Long-term mortality after lower extremity amputation is not well reported in low- and middleincome countries. The primary aim of this study was to report 30-day and one-year mortality after lower extremity amputation in South Africa. The secondary objective was to report risk factors …

Effects of Hip Osteoarthritis on Lower Extremity Joint Contact Forces
… and validate a musculoskeletal model in which lower extremity JCF were calculated at the hip, knee, and ankle in 10 participants with hip OA (H-OA) and 10 healthy control participants using OpenSim 4.0 [simtk.org, 23]. The generic gait2392 model was scaled to participant demographics, then the …

The use of instrumented measures to describe lower extremity joint mechanics
… to quantitatively assess the mechanics of the lower extremity joints as a possible solution to the low repeatability of commonly used clinical tests. It was shown through the use of instrumentation that the torques about the lower leg joint during passive movement could be accurately measured …

Lower Extremity Coordination Pattern Stability During a Single-leg Hop for Distance
… the coordination pattern stability of the lower extremity during a single-leg hop for distance, a commonly used tool in athletic rehabilitation programs and return-to-activity decisions. A dynamical systems analysis was utilized to examine single-leg hop performance of bilaterally healthy …

Computational modeling of trabecular bone in lower extremity injuries due to impact
Lower extremity injuries resulting from improvised explosive devices (IEDs) pose a serious threat to the safety of military troops. Reports from Operation Iraqi Freedom and Operation Enduring Freedom identify IEDs as the cause for a substantial number of lower extremity bone fractures. The Army …

Model and Characterization of a Passive Biomimetic Ankle for Lower Extremity Powered Exoskeleton
Lower extremity powered exoskeletons (LEPE) allow people with spinal cord injury (SCI) to perform activities of daily living, such as standing, walking, or stair and ramp ascent/descent. However, current LEPE walk slowly and require extensive use of forearm crutches to maintain user stability. …

Hand control of bipedal balance in quiet standing: implementations for lower extremity exoskeleton
… that greatly reduces the ability to move their lower extremities. In recent years, lower extremity exoskeletons that apply torques generated by motors to the joints of the person have helped to them stand and walk. This research is a part of an extended project to build a new exoskeleton for use …
