Available in PDF, EPUB and Kindle. Book excerpt: Knee-ankle-foot orthoses (KAFOs) are full leg braces for individuals with knee extensor weakness, designed to support the person during weight bearing activities by preventing knee flexion. KAFOs typically result in an unnatural gait pattern and are primarily used for level ground walking. A novel variable resistance orthotic knee joint was designed and evaluated to address these limitations. This low profile design fits beneath normal clothing. Mechanical and biomechanical testing demonstrated that the design resisted knee motion during stance phase, released the knee joint without restricting the knee's range of movement, and provided flexion resistance during stair descent. Design modifications and related testing procedures were developed to further improve joint performance and to validate the design prior to testing on individuals with knee extensor weakness.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2019-11-20 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technical Report from the year 2019 in the subject Engineering - Mechanical Engineering, grade: 10.00, , language: English, abstract: Ankle foot orthosis (AFO) are externally applied device that a reused to support as well as control the foot and ankle joint of patients having foot deformity. Foot drop is caused by a deficiency in the ankle joint in which results in the weakness of ankle and toe dorsiflexion. This research proposes a new approach to design and performance evaluation of AFO fabrication that utilizes modeling, simulation and analysis software (like Open Sim, Ansys Work bench & Solid work) and additive manufacturing technologies to customize the fit form to an individual. By implementing a carbon fibre strut at ankle joint the design will result in a stronger, more comfortable, more flexible AFO that can adaptively constrain ankle movement for various different activities. GAIT Analysis was performed on six patients having foot drop, from the emotion analysis system in the GAIT lab. The data from the GAIT lab was then imported into the Open Sim to create a biomechanics simulation to extract the joint angle and joint moments. These value of ankle angle and moment with & without AFO was compared with normal value. The results show a considerable effect of the use of the AFO by drop foot patients in terms of ankle angle and ankle moments. Furthermore, the muscular analysis in terms of activation and forces also suggest that the dorsiflexors are assisted by the AFO during GAIT and the activation of the plantarflexion are considerably less during the lifting of the foot of the ground.

Download or read book The Design and Control of Active Ankle foot Orthoses written by Kenneth A. Shorter and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle foot orthoses (AFOs) can be used to ameliorate the impact of impairments to the lower limb neuromuscular motor system that affect gait. Existing AFO technologies include passive devices with fixed and articulated joints, semi-active devices that modulate damping at the joint and active devices that make use of a variety of technologies to produce power to move the foot. Emerging technologies provide a vision for fully powered, untethered AFOs. In this dissertation, a novel portable powered ankle-foot orthosis (PPAFO) cabable of providing un-tethered assistance during gait is presented. The PPAFO provides both plantarflexor and dorsiflexor torque assistance via a bi-directional pneumatic rotary actuator. The system uses a portable pneumatic power source (compressed CO2 bottle) and embedded electronics to control the motion of the foot. Experimental data from two impaired and five healthy subjects were collected to demonstrate design functionality. The impaired subjects had bilateral impairments to the lower legs that caused weakness to the plantarflexors, in one case, and to the dorsiflexors in the other. Data from the healthy walkers demonstrated the PPAFO0́9s capability to provide correctly timed plantarflexor and dorsiflexor assistance during gait. The results from the impaired subjects demonstrated the PPAFO0́9s ability to provide functional assistance during gait. Additionally, this dissertation presented a modeling and control approach to address limitations present in the PPAFO through the introduction of a new hardware configuration and new control architecture. A combined model consisting of both the PPAFO and the human foot and shank segments was first derived and validated. Next, the current and the new PPAFO system configurations were evaluated both in simulation and experimentally during three simplified functional gait tasks: (1) motion control of the foot at the start of the gait cycle, (2) plantarflexor torque assistance during late stance, and (3) dorsiflexor position control of the foot during swing. The resulting analysis showed that the new system configuration both outperformed and was more efficient than the current PPAFO configuration. The stringent design requirements of light weight, small size, high efficiency and low noise make the creation of daily wear assist devices challenging, but once such devices appear they will present new opportunities for clinical treatment of gait abnormalities.
Download or read book Load Analysis of Ankle Foot Orthoses During Gait written by Atichart Kwanyuang and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different causes of gait deficiencies generate different symptoms. It is important for orthotists to gain a better understanding on how to design Ankle Foot Orthoses (AFOs) in order to address individual biomechanical requirements. The loads acting on AFOs during gait are important factors for orthotists to accurately understand so as to design AFOs more effectively. Therefore, the aim of this study is to develop a validated Finite Element (FE) model, which could be used to quantify and analyse the loads acting on an AFO during gait. In this thesis, for mutual comparison and confirmation, pressures acting on the AFO are recorded by two different types of pressure transducers: resistive and capacitive. Trends of the results obtained from the two sensors are similar; however, the magnitudes tend to be different. Furthermore, an accurate digital 3D scanning model of an AFO is captured using the 3D digitiser which can be modified by Computer Aided Design (CAD) software before being exported to Finite Element Analysis (FEA) software to create an FE model. Both the loads measured from the experiment and the assumed constraint during heel off are then applied to the FE model. To make the analysis more complete, a number of features of AFO and a range of FEA methods are conducted. The results are validated by both empirical findings from previous literature and an additional experiment carried out. Based on a healthy subject with no pathological gait, this study reveals that, on the one hand, the AFO is able to assist walking by carrying 6.89% of the overall magnitude of ground reaction force. On the other hand, it resists walking by generating 18.63% in dorsiflexion of the overall magnitude of the moment generated by the plantarflexors. It is therefore claimed that these findings are useful for orthotists involved in fitting AFOs, in order to efficiently design and construct them.
Download or read book Development and Evaluation of a Quick Release Posterior Strut Ankle Foot Orthosis written by Wentao Li and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle foot orthosis (AFO) stiffness affects ankle range of motion but can also provide energy storage and return to improve mobility. To perform multiple activities during the day, a person may want to change their AFO stiffness to meet their activity's demand. Carrying multiple AFO and changing the AFO is inconvenient and could discourage users from engaging in multiple activities. This thesis developed a new quick-release mechanism (QRM) that allows users to easily change posterior strut elements to change AFO stiffness. The QRM attaches to the AFO and requires no tools to operate. The new QRM includes a quick-release key, weight-bearing pin, receptacle anchor, and immobilization pin. A prototype was modelled with SolidWorks and simulated with SolidWorks Simulation. The QRM was designed to have no mechanical failure during intense activities such as downhill walking and running. Unlike a solid screw connection, the QRM needed an additional part to eliminate unsecured motion related to clearance between the quick release key and receptacle anchor. Mechanical test results and measurement data demonstrated no deformation on each part after mechanical testing. User testing revealed that, although the quick release mechanism can be locked or unlocked rapidly, the person's posture when operating can facilitate strut swapping. A learning effect occurred by repeated practice. The Quick Release AFO (QRAFO) prototype verified the manufacturing feasibility of the QRAFO design. Overall, the novel quick release AFO improved strut swapping time without sacrificing device strength.
