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.

Musculoskeletal injuries sustained during physical training and sports-related activities are the greatest threat to military force readiness. Injuries sustained during physical training are one of the principal reasons for the inability of service men and women to be deployed and for the almost 25 million limited duty days accrued annually. Ankle sprains have been shown to be a leading cause for military disability and are a long-term health care issue, potentially leading to a medical discharge. Military parachuting studies have demonstrated the benefits of using an outside-the-boot ankle brace to reduce the risk for sustaining an ankle injury, but the use of ankle bracing on other performance measures in the military have not been established. The first chapter of this dissertation focused on reviewing existing literature that investigated the effects of ankle bracing on functional performance measures in civilian populations. It was concluded in the literature that ankle braces, used in healthy physically active populations, have little statistical impact on balance and functional performance measures. The second chapter of this dissertation focused on reviewing how ankle braces effect performance measures in military specific populations. At this point, only one study has specifically evaluated how these devices affect performance measures, and the remaining studies focused only on the reduction of ankle injuries. Due to the lack of literature available, the purpose of this study was to investigate the effects of ankle braces on dynamic balance and three functional performance measures in a Reserve Officers Training Corps. This randomized crossover study indicated significant results in which ankle braces do create negative effects for balance reach distances, max jump height, max jump distance, and obstacle course completion time. This is the first study to evaluate ankle braces in a military sample while wearing battle dress uniform, combat boots, and a loaded rucksack.

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.

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.
