This book was released on 2020 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anterior cruciate ligament (ACL) ruptures are a common injury in sports with short and long term consequences. Second ACL injury rates, defined as an injury to the contralateral or healthy limb, or a re-graft tear of the reconstructed ACL, are on the rise and can range from 24-49%. Previous literature suggests that quadriceps strength limb symmetry index (LSI) is a predictor of second ACL injury after returning to sport. Since single leg hop tests have been shown to not be a predictor of future second ACL injuries, using a functional task with systematically increased demands may help identify strength asymmetry thresholds at which ACLR individuals lose the ability to biomechanically adapt and present movement profiles that may increase risk for a second ACL injury. Specific to this thesis project, we hypothesized that: 1) ACL reconstructed (ACLR) individuals with [less-than]90% quadriceps strength LSI would exhibit biomechanical asymmetries regardless of task demands compared to ACLR individuals with 3?90% quadriceps strength LSI and healthy controls. 2) ACLR individuals with 3?90% quadriceps strength LSI would exhibit biomechanical asymmetries but only when task demands are highest compared to healthy controls. The two purposes of this study are to determine: 1) the effects of quadriceps strength symmetry and task demands on lower extremity biomechanics in ACLR and healthy controls, 2) evaluate asymmetries in single leg tasks. Data was collected on 10 healthy controls and 10 ACLR individuals that were all physically active and scored on the Tegner survey. All participants were asked to complete three hopping tasks commonly used in return to sport testing: the single leg hop for distance, the triple leg hop for distance, and the 6- meter timed hop. Quadriceps strength was measured using a dynamometer and the results determined our two ACLR groups: ACLR LSI 3?90% and ACLR LSI [less-than]90%. Participants performed three vertical drop jumps each from box heights of 30cm, 45cm, and 60cm. Additionally, participants performed single leg landing and single leg takeoff hops targeting 75% of their maximum single leg hop distance obtained earlier in the protocol. The ACLR LSI [less-than]90% group displayed biomechanical asymmetries during both the drop jump and single leg hopping tasks. The uninjured limb of the ACLR LSI [less-than]90% group displayed significantly higher knee adduction torques upon initial contact with the forceplate compared to the healthy matched control limbs at 30cm and 60cm heights, and ACLR LSI3?90% uninjured limbs at all three landing heights (p=0.018, observed power=0.81). During the single leg hopping trials, the ACLR LSI [less-than]90% group displayed a reduction in quadriceps efforts in their injured limb vs non-injured limb as demonstrated by reduced knee energy generation (hop landing) and absorption (hop takeoff), while also maintaining similar ground reaction forces during both single leg landing and takeoff trials (p=0.005, observed power= 0.90). The current thesis had several limitations that could have masked the results obtained: 1) the ACLR groups had small sample sizes, 2) the Tegner scale scores were statistically different between groups with the highest level of activity present in the ACLR LSI [less-than]90% group. Overall, ACLR LSI [less-than]90% exhibited movement characteristics in both the double leg drop jumps and single leg hopping tasks that suggest they are at heightened risk for a second ACL injury. Future research efforts should substantiate these findings as well as attempt to explain why these movement compensations occur post- ACL reconstruction.

Book Synopsis Biomechanics of Lower Limb Prosthetics by : Mark R. Pitkin
Download or read book Biomechanics of Lower Limb Prosthetics written by Mark R. Pitkin and published by Springer. This book was released on 2009-10-14 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword from a Clinical Biomechanist, Applied Physiologist and Prosthetist teaching graduate students in Prosthetics & Orthotics. While there are many books on Biomechanics, arguably the quintessential science of limb prosthetics, none addresses the fundamental principles in sufficient detail and depth to be practically useful to the prosthetist, rehabilitation specialist or researcher. Dr. Pitkin’s monograph is an exemplary collection of theoretical principles from his research and o- ers, presented in its clinical and applied biomechanics form. The textbook provides an excellent overview of the many facets of lower limb prosthetic design and engineering for the ardent clinician researcher and student. The book delves into many of the basic concepts that are required knowledge for the clinician and the scientist to have as the foundation for their work. Dr. Pitkin has an e- quent manner in which he reflects on the history and literature to tell the storied evolution of prosthetic design . He takes the reader on a journey to consider his theories, which have substantive foundations to contemplate. By the end of chapter one, we have the basic h- tory and an appreciation for the rationale behind the “rolling joint ankle” with evidence to support his theoretical views.
