Book The Effects of Prophylactic Ankle Bracing on Knee and Hip Mechanics in Basketball Players During Jump Landing

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 The Effect of Ankle Prophylactic Bracing on Kinematics of the Lower Body when Landing from a Vertical Jump

Download or read book The Effect of Ankle Prophylactic Bracing on Kinematics of the Lower Body when Landing from a Vertical Jump written by Joshua Paul Rayburn and published by . 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.

Book The Effect of Ankle Bracing on Knee Joint Kinematics and Kinetics During Repeated Single Leg Hop and Drop Vertical Jump in High School Aged Girls

Download or read book The Effect of Ankle Bracing on Knee Joint Kinematics and Kinetics During Repeated Single Leg Hop and Drop Vertical Jump in High School Aged Girls written by Virginia Norene Christensen and published by . 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 Ankle Bracing as a Mediator of the Influence of Attentional Foci on Landing Mechanics in Healthy Females

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 The Effects of Ankle Bracing and Fatigue on Time to Stabilization in Subjects with Chronic Ankle Instability

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.

Book Effects of Ankle Support on Time to Stabilization of Subjects with Stable Ankles

Download or read book Effects of Ankle Support on Time to Stabilization of Subjects with Stable Ankles written by Raquel Elise Martin and published by . 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 Biomechanical Analysis of the Lower Extremities During Cutting Maneuvers with and Without an Ankle Brace

Download or read book Biomechanical Analysis of the Lower Extremities During Cutting Maneuvers with and Without an Ankle Brace written by Jesse Ryan Bethke and published by . This book was released on 2018 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to move is an important component for quality of life. Injury can hamper this component reducing the quality of life. The time needed to recover from injury can have economic, psychological, and emotional impacts. Therefore it is important to determine ways to prevent injuries whenever possible. One common injury occurring to many active people is an inversion ankle sprain. Unfortunately after such an injury the likelihood it may occur again increases due to the decreased ankle stability. To help prevent ankle sprains, individuals can wear external ankle supports such as ankle tape or ankle braces. The latter of the two is reusable, does not degrade with activity, and reduces the risk of ankle injuries. However, with the reduction of the ankle’s range of motion there may be an alteration in the kinetic chain dynamics of the lower extremities, which may have consequences including risk of injury at other joints, including the knee and hip. Females have a four to six fold incidence rate of ACL injuries when compared to men. Additionally 60% of ACL injuries occur during noncontact situations. This study was designed to examine whether the kinetics of the knee and hip, and the angular kinematics of the knee are affected in a female population when wearing an ankle brace during a sidestep cutting maneuver. Sixteen healthy and recreationally active females between the ages of 18-40 performed a number of dynamic movement tasks using of their preferred leg. A total of 24 experimental trials were completed over two sessions (12 in session one and 12 in session two) with half of each sessions trials being straight run throughs and the other half being sidestep cutting maneuvers. Half of the participants wore a brace during their first session (no brace for their second) and the other half did not wear a brace during their first session (brace for their second). The results showed no difference in almost all dependent variables except for knee varus moment between sessions one and two with a p-value less than 0.05. These findings suggest a learning effect occurred and the participants altered their valgus moments without altering knee angular kinematics. Wearing an ankle brace did not increase the injury risk factors for the knee in this task.
