Book excerpt: The use of knee braces prophylactically is still considered as an approach for injury mitigation for those in high-risk sporting activities, though their use is not fully supported. The purpose of this thesis was to examine biomechanical and neuromuscular effects of prophylactic brace wear following standardized repetitive exercise. Twelve participants participated and acted as their own control. The participants were required to participate in two sessions, one control session with no brace and one intervention session with the application of a off-the-shelf prophylactic knee brace. Pre-and post-exercise intervention single leg drop landings were recorded to examine the effects of an acute exercise stimulus on the neuromuscular and biomechanical effects of brace wear. Additionally, trials were collected at 30-minutes post-exercise to examine residual effects of the brace wear on landing kinematics and kinetics. Difference tests using analysis of variance (ANOVA) showed that there was a minimal effect of the prophylactic knee brace on biomechanical and neuromuscular variables following exercise as well as 30-minutes following knee brace removal. Further research may be required to identify if braces can be worn prophylactically to reduce the risk of injury during activity.

This book was released on 2014 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knee is one of the most commonly injured joint in the human body and majority of the injuries are associated with ligaments which have detrimental effects on joint's stability and function. Bracing has often been used as a prominent measure to restrain an unstable joint and for individuals with anterior cruciate ligament (ACL) injury as a post-operative treatment measure. However, it is not known if the brace would protect the ACL of an uninjured person during dynamic activities by reducing the strain in the ACL. Primary objective of this research study was to investigate the effects of knee brace on ACL during dynamic activities. Hence a combined in-vivo/ in-vitro methodology was used to assess the influence of “CTi-Custom” knee brace on ACL strain during drop-landing activity. Motion capture was performed on the drop-landing activity of a high-risk subject with and without knee brace worn. These in-vivo kinetic and kinematic parameters were subsequently input into a biomechanical model to calculate muscle forces that span the knee joint. A hybrid surrogate knee model was prepared using cast foam shell that was wrapped around a cadaver knee specimen to form an artificial interface for mounting a custom fit knee brace during in-vitro simulation. A strain gauge was instrumented on ACL of hybrid surrogate cadaver specimen and mounted on a dynamic knee simulator, where kinematics and muscle forces were applied replicating braced and unbraced drop-landing conditions. This simulation was performed with and without the brace mounted on the cadaver knee specimen and the ACL strain was measured. Observing biomechanical model outputs it was evident that muscle forces for braced and unbraced conditions were different and the knee brace appeared to reduce the ACL antagonist muscle forces thereby dissipating energy, consequently reducing the peak GRF and the internal joint forces. The peak strain in the ACL was radically different for braced (8% strain) and unbraced (18% strain) conditions. However, when unbraced kinetics/kinematics was simulated with brace mounted on the cadaver knee, the ACL strain was not different from the unbraced condition. This enabled us to conclude that the custom fit knee braces reduce the strain in the ACL of high-risk subjects thus preventing them from potential ACL injury. However, any decrease in the ACL strain observed while wearing the brace was due to the brace altering the muscle firing pattern rather than due to the mechanical restraint offered by the brace. This reinforces previous research findings that brace affects proprioceptive feedback and alters the muscle firing pattern.

Download or read book The Influence of Age at Menarche and Hamstrings Fatigue on Knee Biomechanics written by Stephanie Eileen Field and published by . This book was released on 2016 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anterior cruciate ligament (ACL) injury is 4-8 times more likely to occur in females than in males and is associated with significant morbidity. The mechanism underlying the gender disparity in non-contact ACL injuries is likely multifactorial, and may be influenced by a variety of risk factors. This study examines the influence of age at menarche and neuromuscular fatigue of the hamstrings muscles on knee biomechanics. Twelve female athletes performed drop vertical jump (DVJ) tasks before and after a fatiguing protocol utilizing a glute-ham bench. Knee kinematics and kinetics were recorded during the contact phase of the DVJ. The results of this study found a significant decrease in knee abduction angle in the dominant leg after fatigue (P = 0.05), and a significant decrease in peak vertical ground reaction force (vGRF) after fatigue.The findings of this study do not support our hypotheses that (1) age at menarche is correlated with greater dynamic knee valgus, (2) that knee valgus is greater after fatigue, or (3) that the effects of fatigue are exacerbated in females with earlier age at menarche. We concluded that because the glute-ham raise targeted fatigue of the lateral hamstrings (biceps femoris), the exercise caused a decrease in potentially harmful valgus knee angles and moments. The reduction in peak vGRF after fatigue may be a result of an altered landing strategy in order to reduce impact forces and to maintain overall landing mechanics. Understanding the factors that affect knee biomechanics is critical for the development of more effective injury prevention strategies.
