Book Synopsis The Effects of Prophylactic Ankle Bracing on Knee and Hip Mechanics in Basketball Players During Jump Landing by : Riann K. Thayer
Download or read book The Effects of Prophylactic Ankle Bracing on Knee and Hip Mechanics in Basketball Players During Jump Landing written by Riann K. Thayer and published by . This book was released on 2018 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Many athletes of various sports have been required to wear ankle braces for prophylactic uses. Ankle braces have been shown to decrease range of motion in all directions, which means the main force absorption mechanism of the ankle may be inhibited. This decrease in force absorption at the ankle may increase the mechanical demands at the more proximal knee and hip joints. In this study, the change in knee, hip and lower back mechanics will be investigated to gain understanding as to whether bracing the ankle could create a higher injury potential. Methods: In this study, 12 intercollegiate basketball players (6 female, 6 male) participated during one session, in which each subject tested for each taping condition (self-adherent, adhesive cloth, and no tape). For each trial, the participants performed three maximum vertical jump trials and three depth drop trials, a 15-minute bout of exercise, and subsequently three more maximum vertical jumps and three more depth drops. The participants' lower body kinematics and kinetics were measured using 3D motion capture and force plates. Results: Analysis of ankle bracing pre- and post-exercise on lower extremity kinematics and kinetics through a two-way MANOVA yielded results that were not significant for any of the variables, including their interaction effect. There was no effect of the three different types of ankle bracing (control, adhesive, and self-adhesive), exercise (pre-and post-), or the interaction of those variables on peak hip flexion, peak knee flexion, peak knee moment, peak hip moment, and peak lumbosacral moment. Conclusion: Ankle bracing had no effect on selected lower body kinematics and kinetics. More research should be done to better understand whether ankle bracing has the potential to increase injury at other joints.

Book Synopsis Ankle Bracing as a Mediator of the Influence of Attentional Foci on Landing Mechanics in Healthy Females by : Mackenzie Haines
Download or read book Ankle Bracing as a Mediator of the Influence of Attentional Foci on Landing Mechanics in Healthy Females written by Mackenzie Haines and published by . This book was released on 2018 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context: Biomechanics risk factors observed during landing task have been identified such as decreased hip and knee flexion, increased knee valgus, hip adduction and hip external rotation. These patterns have been related to the increase risk for ACL injury and could also be observed with decreased ankle range of motion (ROM). The effects of different forms of attentional focused instruction has been studied and is thought to optimize landing mechanics; decreasing risk for ACL injury. This has not yet been explored in a population with an external mechanical restriction such as an ankle brace. Objective: To determine the effects of lace-up ankle bracing and attentional focused instruction on lower extremity kinematics and kinetics during a landing task in healthy females Design: Crossover. Setting: Laboratory. Participants: 19 healthy females. Inclusion: aged 18-35, physically active with minimal familiarity of drop vertical jump task (DVJ). Exclusion: lower extremity musculoskeletal injury within last 6 months, history of lower extremity injury, vestibular, balance or connective tissue disorders, or history of ankle sprains. Interventions: Independent variables included condition (brace vs. no brace) and mode of attentional focus (external focus (EF) , internal focus (IF), neutral). All participants completed five DVJ trails for each different modes of attentional focus instruction for both bracing conditions. Main Outcome Measures: 3D trunk and lower extremity kinematics and kinetics were analyzed during landing phase of DVJ from initial contact to peak knee flexion Results: Bracing decreased peak ankle dorsiflexion (19.6°± 6.4° vs 25.9°± 5.3°) compared to non-braced. In the bracing vs. nonbraced condition, EF increased peak hip abduction (-3.8°±5.0° vs. -1.7°±4.2°), hip flexion (83.6°±14.3° vs. 79.0°±16.1°), and decreased knee valgus (-13.8°±6.6° vs. - 14.9°± 6.9°). Conclusion: EF instruction can aid in optimizing landing mechanics in healthy female population with mechanical restriction at the ankle is in place.
Book Synopsis The Effects of Ankle Bracing and Fatigue on Time to Stabilization in Subjects with Chronic Ankle Instability by : Sari L. Cattoni
Download or read book The Effects of Ankle Bracing and Fatigue on Time to Stabilization in Subjects with Chronic Ankle Instability written by Sari L. Cattoni and published by . This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is unknown whether the application of an ankle brace can increase dynamic stability to overcome the effects of fatigue in those individuals with CAI. Ankle dynamic stability was assessed before and after a functional fatigue protocol using the Time to Stabilization (TTS) method. Prior to the functional task, dynamic stability was measured using a single leg jump landing at 50% of the subjects' maximum vertical jump height. The functional fatigue circuit was repeated until the time it took to complete the circuit increased to 50% of the baseline time. Immediately after fatigue was reached, the single leg jump landing measures were repeated. This protocol was performed with and without an ankle brace. For APTTS, the main effect for Group was statistically significant (F= 4.15; p= .05). Subjects in the CAI group (1.291"0.179s) took significantly longer to stabilize than those in the healthy group (1.191"0.10s). There were no other significant results found. The results of our study provide questions regarding the use of ankle braces for improving dynamic stability measured with TTS in both a healthy population and those with CAI. Further research, with a larger sample size should be conducted to make a better decision regarding the effectiveness of ankle braces in improving single-leg jump landing stabilization.

This book was released on 2014 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to investigate the effects of the ASO ankle brace and the closed Gibney ankle taping method on kinematics of the lower body when landing from a vertical jump. By observing lower limb joint angular kinematics during landing this study may help to identify if ankle prophylactic bracing may increase the potential risk of injury to the more proximal unstabilized knee and hip joints. For this study, 10 females (age: 18-24 years), were randomly selected from a group (N= 24) of well-trained intercollegiate athletes, who had been competitive for at least 4 years in a jumping sport.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Ankle bracing has not been studied for its effects of knee joint kinematics and kinetics in the adolescent female athlete. Hypothesis: A) A statistically significant mean increase of knee joint valgus and extensor moments and valgus angles would be found in the braced group during the drop vertical jump and the single log hop tests and B) A statistically significant mean decrease in knee joint varus and extensor moments and valgus angles will be found between pre- and post-test acclimation periods in the braced condition. Study Design: Randomized Controlled Trial. Methods: Fifteen adolescent female athletes performed Drop Vertical Jump (DVJ) and Single Leg Hop (SLH) tests without ankle bracing and with a lace-up style ankle brace. Subjects wore braces over a 1 week period and retested. Results: During the DVJ, bracing increased knee extensor moments during the first 50 ms of landing but had no affect on knee frontal plane moments. Bracing increased vertical ground reaction force (vGRF) within the first 50ms of landing, and peak vGRF with less time to achieve peak vGRF. During the SLH, bracing increased knee flexion at IC and decreased knee frontal plane displacement into valgus. Ankle bracing increased vGRF within the first 50ms of landing and decreased stance time. Conclusions: Ankle bracing increased vGRF and knee extensor moments during the first 50ms of landing. Clinical Relevance: The adolscent female athlete may be at risk for knee injury during the initial landing phse when wearing a lace-up style ankle brace.
Book Synopsis The Influence of Residual Fatigue on Lower Limb Stiffness During Jump Landing by : Lindsay Victoria Slater
Download or read book The Influence of Residual Fatigue on Lower Limb Stiffness During Jump Landing written by Lindsay Victoria Slater and published by . This book was released on 2010 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Anterior cruciate ligament (ACL) injuries have become commonplace among female athletes in today's society. With more than 70% of injuries resulting from noncontact mechanisms such as jump landing, the relationship between fatigue and altered movements patterns has become an important topic of research. Purpose: The main purpose of this study was to investigate the influence of residual fatigue on lower extremity kinematics and vertical leg stiffness at landing as experienced by female athletes. Method: The participants in this study were 12 NCAA female intercollegiate soccer players. Participants completed five single-leg drop jumps on their dominant leg every day for 4 days. The first day was completed without intervention to obtain pre-fatigue data and drop jumps on days two through four were completed after a fatigue protocol. Results: A repeated measures MANOVA did not reveal significant differences in post-fatigue peak knee flexion angle, vertical ground reaction forces, or vertical leg stiffness. Despite lack of statistical significance, vertical leg stiffness was increased during post-fatigue testing when compared to pre-fatigue values. Implications: The increased vertical leg stiffness may indicate altered landing techniques in post-fatigue states. If fatigue results in compromised movement patterns, it may explain the increased number of ACL injuries during the end of soccer matches. Suggestions for Future Research: Future research with a larger sample size should include post-fatigue dominant and nondominant leg comparison due to previous conflicting findings regarding which limb is most often injured. Future researchers should also quantify the magnitude of fatigue induced by the fatiguing protocol to document the strength of the independent variable.
