This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Injury to the anterior cruciate ligament (ACL) may have consequences for an athlete in the form of pain, decreased activity levels and early-onset osteoarthritis. Female athletes are at increased risk of injury, perhaps because of differences in neuromuscular function. Methods of identifying risk factors and effective prevention strategies for ACL injury have traditionally involved athletes of high school age or older. However by that age, the opportune time to intervene may have passed. This thesis involves a sequence of studies which measures the neuromuscular function of younger athletes, aged 10-14 years. First, the reliability of measuring strength and power of the lower extremity on an isokinetic dynamometer was explored. Torque and power of the hip flexors and knee extensors were the only measures with acceptable reliability. Conversely, peak velocity of all the tested hip and knee movements demonstrated acceptable reliability. A high amount of variability was found with all test movements, and so alternate tests should be used if measuring an individual athlete's ability. From the data collected within the reliability study, a sex comparison was undertaken to determine if neuromuscular power differed at this young age. It was determined that girls and boys between 10 and 14 years of age do not differ in terms of knee or hip movement velocity or power. There is evidence to suggest that sex differences exist by adulthood; further research is required to determine when the disparity becomes apparent. The final project was to determine whether strength training would improve the manner in which young female athletes land from a jump; a common ACL injury mechanism. This randomized controlled trial found no difference between the intervention group who trained their legs, and the control group who trained their arms. However those athletes with the poorest landings appeared to improve their movement pattern regardless of training regime. This thesis contributes to the literature by providing evidence for measurement protocols for young athletes, introducing neuromuscular power instead of strength into the investigation of contributing factors to injury, and by furthering the examination of strength training as an effective component of prevention programs.

Available in PDF, EPUB and Kindle. Book excerpt: "Female athletes have become the poster children for anterior cruciate ligament (ACL) injuries in recent years. This has lead to increased attention from research. There is now a vast amount of articles about ACL injuries and the library keeps growing. The purpose of this thesis is to review the current literature on ACL injury related to etiology, pathology and prevention. Through my research an additional topic arose. This is highlighted in a further section, psychosocial factors. Original research was conducted to gain a preliminary look at how playing multiple sports at one time, or specializing in one sport in high school, affects injury rates and what was the greatest influence on the decision to play club sports. The results from the literature review revealed that valgus stress at the knee and the imbalance between the force couple of the hamstrings and quadriceps are the most responsive to correction through training. The research supports that by correcting those two etiological risk factors female athletes can reduce their risk for ACL injury. Additional research is needed to look at how psychosocial factors [are] related to ACL injuries"--Abstract.

This book was released on 2016-08-31 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Anterior cruciate ligament (ACL) injury is a severe and common injury, and females have 2-4 times higher injury risk compared to men. Return to sport (RTS) is a common goal after an ACL reconstruction (ACLR), but only about two thirds of patients RTS. Young patients who RTS may have a 30-40 times increased risk of sustaining an additional ACL injury to the ipsi- or contralateral knee compared with an uninjured person. Aims: The overall aim of this thesis was to increase the knowledge about female football players with ACLR, and patients with bilateral ACL injuries, and to identify predictors for additional ipsi- and/or contralateral ACLR. Methods: This thesis comprises four studies. Study I and II were cross-sectional, including females who sustained a primary ACL rupture while playing football and underwent ACLR 6–36 months prior to study inclusion. In study I, 182 females were included at a median of 18 months (IQR 13) after ACLR. All players completed a battery of questionnaires. Ninety-four players (52%) returned to football and were playing at the time of completing the questionnaires, and 88 (48%) had not returned. In study II, 77 of the 94 active female football players (from study I) with an ACLR and 77 kneehealthy female football players were included. A battery of tests was used to assess postural control (the Star excursion balance test) and hop performance (the one-leg hop for distance, the five jump test and the side hop). Movement asymmetries in the lower limbs and trunk were assessed with the drop vertical jump and the tuck jump using two-dimensional analyses. Study III, was a cohort study including all patients with a primary ACLR (n=22,429) registered in the Swedish national ACL register between January 2005 and February 2013. Data extracted from the register to identify predictors for additional ACLR were: patient age at primary ACLR, sex, activity performed at the time of ACL injury, primary injury to the right- or left knee, time between injury and primary ACLR, presence of any concomitant injuries, graft type, Knee injury and Osteoarthritis Outcome Score and Euroqol Index Five Dimensions measured pre-operatively. Study IV was cross-sectional. In this study, patient-reported knee function, quality of life and activity level in 66 patients with bilateral ACL injuries was investigated and outcomes were compared with 182 patients with unilateral ACLR. Results: Factors associated with returning to football in females were; short time between injury and ACLR (0–3 months, OR 5.6; 3–12 months OR 4.7 vs. reference group >12 months) and high motivation (study I). In all functional tests, the reconstructed and uninvolved limbs did not differ, and players with ACLR and controls differed only minimally. Nine to 49% of the players with ACLR and controls had side-to-side differences and movement asymmetries and only one fifth had results that met the recommended guidelines for successful outcome on all the different tests (study II). Main predictors for revision and contralateral ACLR were younger age (fourfold increased rate for <16 vs. >35-year-old patients), having ACLR early after the primary injury (two to threefold increased rate for ACLR within 3 months vs. >12 months), and incurring the primary injury while playing football (study III). Patients with bilateral ACL injuries reported poorer knee function and quality of life compared to those who had undergone unilateral ACLR. They had a high activity level before their first and second ACL injuries but an impaired activity level at follow-up after their second injury (study IV). Conclusions: Female football players who returned to football after an ACLR had high motivation and had undergone ACLR within one year after injury. Players with ACLR had similar functional performance to healthy controls. Movement asymmetries, which in previous studies have been associated with increased risk for primary and secondary ACL injury, occurred to a high degree in both groups. The rate of additional ACLR seemed to be increased in a selected group of young patients who desire to return to strenuous sports like football quickly after primary ACLR. Sustaining a contralateral ACL injury led to impaired knee function and activity level.

Download or read book Understanding and Preventing Anterior Cruciate Ligament Injuries Using Novel Motion Analysis Systems written by Ariel Veronica Dowling and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this dissertation is to use novel motion analysis systems to investigate the underlying mechanisms that cause an anterior cruciate ligament (ACL) injury and then to explore movement modification methods that might prevent ACL injuries from occurring. Additionally, novel motion analysis systems can provide new information about ACL injuries and therefore should be used to help analyze these injuries from a different perspective. This thesis provides the results from multiple experimental studies that used two novel motion analysis systems to investigate the underlying causes of ACL injury and potential injury prevention methods. Using a markerless motion capture system, the first investigation determined that increasing the coefficient of friction of the shoe-surface condition will change a subject's movement strategies during a sidestep cutting task in specific ways that may increase the risk of ACL injury. This investigation provides a biomechanical basis for the increased incidence of ACL injuries on high friction surfaces, and suggests that females are more at risk for ACL injury when cutting on high friction surfaces. In terms of novel motion analysis systems, there is a need for simple, cost effective methods to identify athletes at a higher risk for ACL injury during jumping tasks. As such, the second study assessed the capacity of a wearable inertial-based system to evaluate ACL injury risk during jumping tasks. The proposed system measured the knee flexion angle and the trunk lean, and demonstrated good concurrent validity and discriminative performance in terms of the known risk factors for ACL injury. This study also reported the angular velocity of the thigh and shank segments during bilateral and unilateral drop jumps for the first time. Furthermore, this study illustrated that there is an association between the coronal segment angular velocity and knee abduction moment, and that the coronal segment angular velocity can differentiate between subjects at higher risk for ACL injury. Recent studies have shown that the incidence of ACL injury can be decreased through the use of intervention programs. Therefore, the objective for the final study was to determine if an independent inertial-based system can be used to modify jump landing mechanics in order to decrease the risk for ACL injury by providing real-time feedback based on known kinematic and kinetic injury risk factors. This study found that the subjects reduced their risk for ACL injury after training with the system because there were significant increases in the maximum knee flexion angle and the maximum trunk lean. The subjects also reduced their risk for injury by decreasing their thigh coronal angular velocity, which was correlated with a decrease in their knee abduction moment. This study suggests that an inertial-based system could be used for interventional training aimed at reducing the risk for ACL injury.

This book was released on 2015 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problem: It is known that anterior cruciate ligament (ACL) tears are significantly more common in female athletes than male athletes. Research has looked at anatomical, hormonal and biomechanical risk factors for ACL tears in female athletes. Biomechanical risk factors are an important focus when discussing ACL injury prevention because biomechanical deviations have potential for correction with the appropriate training. Methods: The Weill Cornell Medical College electronic libraries were used to conduct the literature search. The literature search was accomplished using PubMed with the key words `ACL injuries AND female athletes' and `ACL injury prevention AND neuromuscular training program'. The search was limited to articles published within the last 5 years. There were 11 additional articles from earlier years and one additional source included because of their significance to the topic and later research was dependent on results of these previous studies. Results: The articles included in the literature review provided specifics about modifiable risk factors for ACL tears in female athletes. Biomechanical risk factors provide the best avenue for ACL injury prevention through neuromuscular training programs. Conclusions: Future research should continue to analyze the specific neuromuscular training programs that provide the most effective ACL injury prevention and the age group when implementing training is most effective. Currently, studies have focused on neuromuscular training programs for club, high school and collegiate athletes and the programs show injury reduction.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Well controlled Anterior Cruciate Ligament (ACL) injury prevention neuromuscular training reduces the risk of ACL injury by 50%, but despite the efficacy of these programs, ACL injury rates have not decreased. This lack of decrease in injury incidence may be due in part to limited knowledge on who is most at risk for sustaining an ACL injury, and there is no formal clinical tool available to estimate the personalized or group risk of ACL injury. The purpose of this study was to better understand what groups of athletes are most at risk of sustaining a primary ACL injury, as the first step in mitigating risk and decreasing the substantial public health and financial burden of ACL injuries. To accomplish this goal, we conducted a systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and through specific inclusion/exclusion criteria to analyze specific subgroupings of athletes. 7,038 studies were identified in the initial database search and 80 studies were included in the final subgroup meta-analysis. Analyses revealed that female athletes had a greater risk of ACL injury compared to male athletes. However, this project pointed out gaps in the current epidemiological prevalence of ACL injuries and the extra precaution people should take about the overgeneralization of sex and sport types for risk assessment. For example, it is well known that for sex comparable sports, females are at greater risk for ACL injury compared to males - however, the absolute risk level for various female sports is substantially low (e.g., female high school volleyball and female college lacrosse). In addition, female professional sports have overall higher ACL injury rates and prevention programs appear less effective for this group warranting more rigorous and targeted prevention efforts. Future studies should also utilize rigorous epidemiological approaches to assess injury rates as there are many sports, sex, and levels that do not have sufficient data to determine absolute prevalence or risk level. When more information is discovered, a personalized risk assessment tool can then be developed to then determine the most at-risk populations to allocate resources and prevention efforts to reduce the number of ACL injuries.
