Objective: To determine if application of fibular reposition tape (FRT) has any effect on ankle, knee, or hip kinematic, kinetics as well as vertical ground reaction forces (vGRFs) during gait in individuals with chronic ankle instability (CAI). Design: Cross over repeated measures laboratory study. Subjects: Twenty active individuals with bilateral CAI (age = 21.5 ± 4.1 years, height = 170 ± 7.5 cm, mass = 81.8 ± 22 kg). Measurements: Time series curve analysis were used for group comparisons. Groups included FRT, Sham FRT, and no tape. Measurements included ankle, knee, and hip kinematics and kinetics in the sagittal, frontal, and transverse planes throughout the entire gait cycle as well as vGRFs during the stance phase. Results: There were no significant differences when comparing the no tape and sham FRT groups for all variables across the entire gait cycle. Additionally, there were no significant results when comparing the sham FRT and FRT groups for all variables across the entire gait cycle. Conclusion: Application of FRT did not have any effect on ankle, knee, or hip kinematics or kinetics across the entire gait cycle as well as vGRFs during the stance phase in individuals with CAI.

Context: External stabilizing devices serve to limit the range of motion of the involved joint. As the most common injury in collegiate athletes, ankle injuries are frequently supported by external devices such as external ankle tape. Changes in biomechanical values at the ankle may result in changes up the kinetic chain. By using external ankle tape, clinicians may be increasing the risk of pathology in the athletic population. However, no research exits to support this theory. Objective: To compare the effect of external ankle taping on knee and hip kinematics and kinetics compared to no taping during an anticipated sidestep cutting task and a straight sprint task. Study Design: Cross-over study. Setting: Laboratory. Participants: 16 healthy males (Age: 23.1±2.6years, Mass: 81.4±11.4kg, height: 181.7±7.3cm) with no history of lower extremity surgery, lower extremity injury in the past six months or any vestibular or balance disorders. Intervention: Participants completed both an external taping technique and a no taping condition. Main Outcome Measures: Three-dimensional kinematics and kinetics were collected with a 12-camera motion capture system and in-ground force plate. Participants completed 5 trials each of a sprint and an anticipated side-step cut with or without external ankle taping. Group means and associated 90% confidence intervals were plotted, with significance being identified when the confidence intervals did not overlap for three consecutive data points. Results: No significant differences in speed, kinetics, or kinematics were identified between conditions for the tasks. Conclusion: External ankle tape did not have a significant effect on the kinetics or kinematics in healthy adult males during a sprinting or anticipated side-step cutting task. However, the basis of the study was dependent on the assumption that ankle kinematics and kinetics would be changed. Future research should evaluate potential influences of external taping on lower extremity function in female or pathological participants.

Lower extremity musculoskeletal injuries are a common occurrence that can threaten deployment, completion of duty, and quality of life for a soldier. Repetitive activities, explosive movements, impact forces, and extreme joint angles all increase risk for injury and are often found in military physical training. Addition of external loading is necessary for combat situations and can lead to biomechanical alterations in gait, landing, and reactive forces, even at small bodyweight-relative loads. Although external load might not be able to be manipulated, individual strength levels and appropriate landing technique may reduce the relative risk for injury. The purpose of this study was to determine how a combat-relative body-borne loads can affect lower extremity biomechanics in Reserve Officers' Training Core cadets utilizing 3D motion capture and in-ground force plate analysis. Twenty-five college-aged Ohio University Reserve Officer's Training Core cadets and military personnel conducted two series of three consecutive jump landings from a 30cm high box placed half their height from the landing position on two force plates. The testing series consisted of an unweighted baseline condition and a weighted condition of 35% of their bodyweight added to their person by the way of a tactical weighted vest. Unloaded baseline and weighted conditions were compared using a paired t-test and 95% confidence intervals (p

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.

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.
