Book E MAG active a newer stance control knee ankle foot orthosis SCKAFO in the context of workers compensation

Download or read book E MAG active a newer stance control knee ankle foot orthosis SCKAFO in the context of workers compensation written by and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: SCKAFOs may utilize various mechanisms, but in general are designed for locking the knee joint during the stance phase of gait and unlocking it (allowing the knee to bend) during the swing phase. [...] With the stance control feature, flexion of the knee is blocked during stance, the weight-bearing phase of the gait. [...] In the same article, a quote by G. Bedard points out that out of 500 attendees of the 2007 Annual Meeting and Scientific Symposium of the American Academy of Orthotists and Prosthetists, only "30 percent had any experience in providing SCOs; only 15 percent had fitted as many as five; and only two people had fitted ten or more." The issue of reimbursement was also mentioned. [...] When prescribing SCKAFOs and selecting the most appropriate one for the patient, the following 14, 15 factors should be taken into account, according to the manufacturer: - age and cognitive state of the patient - diagnosis and prognosis - biomechanics of the muscles and joints, such as muscle strength and range of motion - contraindications - properties of the candidate SCKAFOs (cost, size, weigh [...] The intelligent sensors of E-MAG Active are placed to measure the 17 position of the leg and to control the orthotic joint system accordingly.

Book Prescription of a Passive dynamic Additive manufactured Ankle foot Orthosis on a Patient with a Severe Trimalleolar Fracture

Download or read book Prescription of a Passive dynamic Additive manufactured Ankle foot Orthosis on a Patient with a Severe Trimalleolar Fracture written by Luke Nigro and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this study are to better understand the gait mechanics of a patient with an ankle fracture, and to provide a prescription for a rehabilitative device, known as a passive-dynamic ankle-foot orthosis (PD-AFO) in order to restore functional gait. One 58-year-old female subject recovering from a trimalleolar fracture (three fractures across both the medial and lateral malleoli) sustained from high-impact trauma was recruited for this study. Gait kinematics and ground reaction forces of the subject walking at a slow and fast pace were captured by a passive-marker camera-based motion analysis system and a floor-mounted force plate, respectively. An 8-segment biomechanical model was built based on several of the subjects anatomical landmarks and used to compute joint moments about the ankle, knee, and hip of both legs. Based on these kinetic metrics and the anatomy of the subject, a PD-AFO was designed in computer-aided design (CAD) software and verified through finite element analysis (FEA) to assist the subject by adding passive stiffness about the ankle, were it to be constructed. Results show that the subject utilized much less range of motion, and produced a much lower peak moment about the mediolateral axis in the injured ankle than the uninjured ankle at both walking speeds. Frequency and time-frequency analysis of the joint kinematics show slight differences in coordination between joints of the injured and uninjured legs at different frequencies. Residuals of joint angles, after being fit with a Fourier series, had generally higher standard deviations during slow walking, showing that the subject had less consistent joint angle ranges, perhaps due to a lack of stability. Finite element testing of the PD-AFO load showed the design is resolute enough to withstand normal loading during walking for the subject and can act as an additional stiffness component.

Book Design and Evaluation of a Variable Resistance Orthotic Knee Joint

Download or read book Design and Evaluation of a Variable Resistance Orthotic Knee Joint written by Andrew Herbert-Copley and published by . This book was released on 2015 with total page pages. 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.

Book Management of Spinal Cord Injuries

Download or read book Management of Spinal Cord Injuries written by Lisa Harvey and published by Elsevier Health Sciences. This book was released on 2008-01-10 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining 25 years of clinical, research and teaching experience, Dr Lisa Harvey provides an innovative 5-step approach to the physiotherapy management of people with spinal cord injury. Based on the International Classification of Functioning, this approach emphasises the importance of setting goals which are purposeful and meaningful to the patient. These goals are related to performance of motor tasks analysed in terms of 6 key impairments. The assessment and treatment performance of each of these impairments for people with spinal cord injury is described in the following chapters: training motor tasks strength training contracture management pain management respiratory management cardiovascular fitness training Dr Harvey develops readers' problem-solving skills equipping them to manage all types of spinal cord injuries. Central to these skills is an understanding of how people with different patterns of paralysis perform motor tasks and the importance of differentmuscles for motor tasks such as: transfers and bed mobility of people wheelchair mobility hand function for people with tetraplegia standing and walking with lower limb paralysis This book is for students and junior physiotherapists with little or no experience in the area of spinal cord injury but with a general understanding of the principles of physiotherapy. It is also a useful tool for experienced clinicians, including those keen to explore the evidence base that supports different physiotherapy interventions.

Book Tuning a Custom Made Solid Ankle foot Orthosis in Early Stroke Rehabilitation

Download or read book Tuning a Custom Made Solid Ankle foot Orthosis in Early Stroke Rehabilitation written by Melissa Rodgers and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tuning ankle-foot orthoses (AFO) involves adjusting the design for biomechanical optimisation to improve gait. Research conlcuded only half of NHS orthotists execute tuning with lack of three-dimensional (3D) equipment a restricting factor. The study had three aims: first to investigate spatiotemporal and kinematic effects of fitting and tuning AFO on gait of acute stroke, compared to un-tuned AFO; secondly, to evaluate use of novel 3d gait analysis system which provided point of care feedback; and finally to establish any difference to tuning prescription between the novel system and observational gait analysis (OGA) by a NHS orthotist. Two males participated. Both presented hemiplegia in the lower limbs following a recent stroke and had been precribed a custom-made solid AFO which was tuned by the NHS orthotist using OGA. Gait analysis and tuning were also carried out using novel system producing point of care feedback of the following trials; treadmill, walking with shoes only, un-tuned AFO and during tuning. The software indicated the same wedge as the orthotist chose using OGA. Walking velocity and step symmetry increased for both patients with AFO. P1 achieved highest velocity and step-length with the un-tuned AFO. This was rejected as it caused excessive knee flexion throughout the gait cycle. Cadence increased for P2 and decreased for P1. P2's step length decreased with the use of an AFO. Neither patient achieved normal kinemtaic profiles for the hip, knee or ankle with the use of a tuned or un-tuned AFO.
