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.

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.

This book was released on 2018 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle braces are often used by athletic trainers across the nation in hopes of preventing ankle related injuries. Since prophylactic ankle braces are widely used and accepted, it is critical to understand the effects prophylactic ankle braces are having on ankle functionality and postural control both in a braced and non-braced state. However, the effects of prophylactic ankle braces over the period of a season has limited research. Thirteen collegiate women's basketball players, who are required to wear prophylactic ankle braces through a 20-week season, participated in this study. The purpose of this study was to determine the effect of prophylactic ankle bracing on passive range of motion, static balance (COG displacement, COG pattern tracking over a period of time), and dynamic balance (COG displacement in a dynamic setting, COG pattern tracking over a period, reach measures through SEBT) in collegiate women's basketball players across a 20-week season span. We rejected the null hypothesis and found differences in ROM, increases in Postural Stability scores, and improvements with Limits of Stability (LOS) scores. We also found a significant decrease in the anterior/lateral quadrant of the ASL test which suggests a change in COG placement over the 20-week span of the season. Although wearing prophylactic ankle bracing over the period of season showed shifts in ROM, improvements in COG location and postural stability scores, further research is needed on wearing ankle braces over a long period of time to determine when these changes are happening.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine if prophylactic ankle tape and/or ankle braces improve dynamic stability in TTS measure. All subjects were healthy and had no prior history of ankle injuries. Data collection consisted of each subject performing a single leg jump-landing with ankle tape, ankle brace, combination of the two, and control (no tape or brace) conditions. Dynamic stability was assessed with time to stabilization force plate measure. Significant plane by ankle tape interaction (p=0.045) was found. No significant plane by ankle tape by ankle brace interaction (p=0.637), no significant ankle tape by ankle brace interaction (p=0.483), or plane by ankle brace interaction (p=0.697) were found. A notable finding was that subjects took longer to stabilize in the anterior/posterior direction than medial/lateral direction. In conclusion ankle tape, ankle brace, and the combination of ankle tape and ankle brace did not statistically improve dynamic stability in healthy ankles.
Book Synopsis Ankle Bracing as a Mediator of the Influence of Attentional Foci on Landing Mechanics in Healthy Females by : Mackenzie Haines

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 Self-adherent Taping on Peak Inversion Angle and Eversion Moment Upon Landing During a Maximal Vertical Jump and a Depth Drop by : Christopher M. Gregoire

Gregoire and published by . This book was released on 2018 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle injuries are the most common injury in physically active adults with roughly 15% to 30% of all physical activity injuries being ankle injuries. The purpose of this study is to evaluate the effectiveness of a self-adherent ankle taping in reducing peak ankle inversion angle and peak ankle eversion moment upon landing during a max vertical jump and depth drop compared to jumping without a prophylactic ankle stabilizer. Twelve volunteers participated in testing procedure on two separate days. Day one consisted of orientation while day two consisted of experimental data collection. The participant's peak inversion angle and eversion moment were measured using 3D motion capture software and force plates during landing from a maximal vertical jump and depth drop. In support of our hypothesis, peak ankle inversion angle during landing decreased 19% as a result of wearing self-adhesive tape when compared to adhesive tape (p= .002). Additionally, peak inversion angle upon landing from a depth drop was 20% less with self-adherent tape as compared to adhesive tape (p= .018). Despite the differences in peak inversion angles, the subjects experienced nearly identical peak ankle eversion moments during the landing phase of both a vertical jump as well as a depth drop both before and after exercise. In conclusion, self-adherent tape showed promise as an alternative to standard adhesive tape in restricting peak ankle inversion. When comparing self-adhesive tape to adhesive tape, the difference in peak inversion angle remains the only advantage of self-adherent tape found by this study.
