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.

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.

Download or read book Effect of Ankle Stabilzers on Vertical Jump, Agility, and Dynamic Balance written by Jatin P. Ambegaonkar and published by . This book was released on 2003 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The current study compared the effects of ankle stabilizers on the vertical jump, agility, and dynamic balance performance. The ankle stabilizers utilized were Swede-O Ankle Lok Brace, Air-Cast Air-Stirrup Ankle Brace, athletic taping, and the nonsupport condition. Vertical jump performance was measured using the vertical jump test, agility performance was measured using the Right-Boomerang Run test, and dynamic balance performance was measured using the Modified Bass Test of Dynamic Balance. No statistically significant (p = .27) difference existed in the heights of the jumps performed by participants (N = 10) in the vertical jump test. No statistically significant difference (p = .08) existed in the points obtained by participants in the Modified Bass Test of Dynamic Balance. A statistically significant difference (p = .03) existed in the run times obtained by participants in the Right Boomerang Run test for agility. A post-hoc Bonferroni test did not show any significant differences in the pairwise comparisons. Standardized effect sizes revealed similar decrements in performance when using any type of ankle stabilizer in comparison to the nonsupport condition. Ankle stabilizers are primarily designed to restrict inversion and eversion of the ankles. Vertical jumping mostly requires dorsiflexion and plantarflexion, and thus might not be affected when using ankle stabilizers. The rigidity offered by the ankle stabilizers might make it more difficult for the participants to change direction quickly enough, which could hinder have hindered agility performance. The test for dynamic balance did not require quick changes in direction. As ankle tape was custom-molded for every participant, the Swede-O Ankle Lok Brace was worn like regular shoes, and the ability to change directions quickly, which is negatively affected when using the Air Cast Air-Stirrup ankle brace was not tested for dynamic balance, the dynamic balance performance was probably not negatively affected when using any ankle stabilizer.

This book was released on 2000 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle taped, braced, and bare. Therefore, each subject performed eighteen total test jumps for this study. Performance of single-leg vertical jumps initiated from various stride run-up lengths was not significantly affected by ankle taping or bracing. This study failed to show a statistical significance in decreased vertical jump heights in subjects with taped and braced ankles when compared to vertical jump heights in subjects with bare ankles. Ankle taping and bracing are widely accepted practices in sports medicine for injury rehabilitation and prevention. Taping and bracing a sprained ankle allowed athletes to return to sport quickly and safely after sustaining an injury. Researchers found both taping and bracing a sprained ankle reduced the occurrence of reinjury. Athletes often will not compromise performance for safety and injury prevention. Therefore, the chosen prosthetics must not hinder performance as they offer protection. Otherwise, athletes will not be compliant.

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.

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.

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 2008 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this study was to compare a lace-up ankle brace with a no-brace condition on the ability to return an athlete with CAI to a stable state by measuring the TTS following a jump-landing task. Design: Repeated measures within-subject design. Setting: Athletic Training Research Laboratory. Patients or Participants: Ten subjects, five males and five females (18.5625±.814yr; 174.0963±7.191cm; 69.2937±8.277kg) that fit the criteria for chronic ankle instability participated in this study. Measurements: Subjects participated in two separate testing sessions during which a jump-landing task was performed with one of two conditions: lace-up ankle brace or no ankle brace. The brace condition was randomized. During each session, five trials of a jump-landing task were performed on each leg. The jump-landing task consisted of a single-leg landing from a double-leg jump height equivalent to 50% of the subject's maximum jump height. Subjects jumped off of both feet from a distance 70cm away from the center of the force plate, reached up and touched the indicated marker, and landed on the force plate on a single test limb. The landing leg was randomized. Ground reaction forces were used to calculate TTS in the medial/lateral (MLTTS) and anterior/posterior (APTTS) directions. The independent variables were Condition (brace, no brace) and Side (injured, non-injured). A separate two-within (Condition, Side) repeated measures ANOVA was performed for APTTS and MLTTS. Main Outcome Measure(s): APTTS and MLTTS. Results: For APTTS, the Side by Condition interaction was not statistically significant (F1,9 = .004; p=.952). For MLTTS, the Side by Condition interaction was not statistically significant (F1,9 = .023; p= .884). No measurements were found to be statistically significant in either direction. Conclusion: This study was designed to show if the use of an ankle brace, like the Swede-O Universal would assist those subjects with CAI in reducing the amount of time it takes for them to stabilize after a jump landing task. Although the results of this study do not support these conclusions with statistical significance, it may provide an important direction in examining the connection between TTS, ankle bracing, and those with CAI. There is a definite need for further testing on more subjects with CAI so we can make a better conclusion about the use of the Swede-O Universal and its ability to reduce time to stabilization after a jump-landing task.
