This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomechanical analysis has been used by many to evaluate upper extremity (UE) motion during human movement, including during the use of assistive devices such as crutches and walkers. However, few studies have been conducted to examine the upper extremity kinetics during wheelchair mobility, specifically within the pediatric population. In 2000, 90% of wheelchair users (1.5 million people) in the United States were manual wheelchair users, requiring the use of their upper body to maneuver the wheelchair as well as perform other activities of daily living. Among children under the age of 18, the wheelchair was the most used assistive mobility device at 0.12% of the USA population (about 88,000 children). Of these children, 89.9% (79,000) use manual wheelchairs. Associated with the leading causes of assistive mobility device usage in children and adolescents, are severe cases of osteogenesis imperfecta (OI), cerebral palsy (CP), myelomeningocele (MM) and spinal cord injury (SCI). Once confined to a wheelchair, the upper extremities must take over the responsibilities of the lower extremities, including mobility and other activities of daily living. For many individuals who are wheelchair-bound since childhood, pain and other pathological symptoms present by their mid to late 20{u2019}s. Due to increased life expectancy and continual wheelchair use, these injuries may cause the user to have reduced, or loss of, independent function as they age, further decreasing quality-of-life. Better knowledge of upper extremity dynamics during wheelchair propulsion can improve understanding of the onset and propagation of UE pathologies. This may lead to improvements in wheelchair prescription, design, training, and long-term/transitional care. Thereby, pathology onset may be slowed or prevented, and quality of life restored. In order to better understand and model the UE joints during wheelchair mobility three main goals must be accomplished: 1. Create an upper extremity kinematic model including: additional segments, more accurate representations of segments and joint locations, consideration of ease of use in the clinical setting with children. 2. Create the corresponding kinetic model to determine the forces and moments occurring at each joint. 3. Implement the model and collect preliminary data from children with UE pathology.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Introduction: A manual wheelchair (MWC) is an essential assistive device that enhances locomotion for individuals with restricted mobility. Unfortunately, 30% to 70% of total MWC users experience upper extremity pain due to repetitive propulsion. One fundamental aspect of MWC propulsion is a stroke pattern, of which one pattern is the semicircular (SC) pattern in which the hands return below the pushrim after a stroke. This pattern is favoured by MWC users, since it may help to decrease the prevalence of shoulder pain. To reduce the prevalence of upper extremity pain and injury for MWC users, research has identified critical changes in some of the specific parameters of MWC propulsion. In our lab, we have developed a low-cost virtual reality simulator that consists of a hardware interface that enables users to control a virtual MWC displayed on a screen, and which also provides force feedback. The present study measures push time, cycle time, velocity, and the contact angle of MWC propulsion, so users also can improve their stroke pattern. Objective: To determine the accuracy and precision of the MWC simulator for measuring the crucial biomechanical parameters of the MWC propulsion technique of young-health individuals when compared to a gold standard system. Methods: We recruited 12 healthy individuals through personal contacts. Participants propelled the MWC in a straight-line and an ecological scenario in the VR simulator. During the straightline scenario, participants propelled MWC at each of eight increasing stroke cadences--in synchronization with metronome beats--using two different propulsion patterns (SC and arcing (ARC)). Then, the participants propelled the MWC in an ecological scenario: an outdoor sidewalk scene that included side slopes, straight slopes, static obstacles, and a street crossing. Push time, vi cycle time, contact angle, and velocity were recorded simultaneously by the MWC simulator and the instrumented wheels (the SMARTWheel system) installed on the MWC. To analyze the collected data, we first calibrated the contact angle and velocity measured by the simulator by performing a regression analysis using the same variables measured by the SMARTWheel system. In the straight-line scenario, we compared the measurements of push time, cycle time, contact angle, and velocity by the simulator and the SMARTWheel by using a Bland-Altman analysis, which was done separately for each propulsion pattern (ARC and SC). Furthermore, we compared the effects of target cadence, propulsion pattern, and instrument measurements by using a mixedmodel analysis. For the ecological scenario, in which propulsion pattern and cadence were unconstrained, we compared the measurements of cycle time, push time, contact angle, and velocity by the simulator and SMARTWheel by using Bland-Altman and mixed-model analyses. Results: The measurements of the simulator and SMARTWheel were not influenced by the propulsion pattern (ARC and SC) or targeted cadence. All the measured variables in the straight-line scenario and ecological scenario were accurate but not precise. Among all the variables of interest, a good precision was achieved only for the measurement of cycle time during the straight-line scenario. For that measurement, the precision corresponded to 10% and 14% of the change due to training for propulsion with the ARC and SC patterns, respectively, with a 95% certainty. Discussion: The wheelchair propulsion variables measured during the straight-line and ecological scenarios were accurate, but, unfortunately, a targeted precision was not attained. However, the precision of the simulator measurements could be enhanced potentially by taking repeated measurements of the same condition. This study demonstrates that important MWC propulsion parameters can be measured accurately by a simulator during straight-line movements"--

Available in PDF, EPUB and Kindle. Book excerpt: During last couple of years there has been an increasing recognition that problems arising in biology or related to medicine really need a multidisciplinary approach. For this reason some special branches of both applied theoretical physics and mathematics have recently emerged such as biomechanics, mechanobiology, mathematical biology, biothermodynamics. The Biomechanics in Application is focusing on experimental praxis and clinical findings. The first section is devoted to Injury and clinical biomechanics including overview of the biomechanics of musculoskeletal injury, distraction osteogenesis in mandible, or consequences of drilling. The next section is on Spine biomechanics with biomechanical models for upper limb after spinal cord injury and an animal model looking at changes occurring as a consequence of spinal cord injury. Section Musculoskeletal Biomechanics includes the chapter which is devoted to dynamical stability of lumbo-pelvi-femoral complex which involves analysis of relationship among appropriate anatomical structures in this region. The fourth section is on Human and Animal Biomechanics with contributions from foot biomechanics and chewing rhythms in mammals, or adaptations of bats. The last section, Sport Biomechanics, is discussing various measurement techniques for assessment and analysis of movement and two applications in swimming.
