Context: Ankle-dorsiflexion (DF) range of motion (ROM) may influence movement variables that are known to affect anterior cruciate ligament loading, such as knee valgus and flexion. To our knowledge, researchers have not studied individuals with limited or normal ankle DF-ROM investigate the relationship between those factors lower extremity patterns associated injury. Objective: determine, using 2 different measurement techniques, whether knee- ankle-joint kinematics differ participants...
Knee valgus is a potential risk factor for lower extremity (LE) injuries. Clinical movement screenings and passive range of motion (PROM) measurements may help identify neuromuscular patterns, which contribute to knee valgus. The purpose this study was compare LE muscle activation PROM between subjects who display visual medial displacement (MKD) during single leg squat (SLS) those do not. We hypothesized that muscular would differ the groups. Forty physically active adults (20 controls, 20...
Excessive trunk motion and deficits in neuromuscular control (NMC) of the lumbopelvic hip complex are risk factors for anterior cruciate ligament (ACL) injury. However, relationship between motion, NMC complex, triplanar knee loads during a sidestep cutting task has not been examined.To determine if there is an association multiplanar with ACL injury task.Descriptive laboratory study.The biomechanics 30 participants (15 male, 15 female) were analyzed using optoelectric camera system...

J Strength Cond Res 27(4): 1083–1090, 2013—Traditional weight programs use an exercise prescription strategy that emphasizes improving muscle strength through resistance exercises. Other factors, such as stability, endurance, movement quality, power, flexibility, speed, agility are also essential elements to overall functional performance....
ABSTRACT The study sought to determine the association between gait biomechanics (vertical ground reaction force [vGRF], vGRF loading rate [vGRF‐LR]) collected 6 months following anterior cruciate ligament reconstruction (ACLR) with patient‐reported outcomes at 12 ACLR. Walking and all subsections of Knee Injury Osteoarthritis Outcomes Score (KOOS) were ACLR, respectively, in 25 individuals a unilateral Peak peak instantaneous vGRF‐LR extracted from first 50% stance phase. Limb symmetry...
Background: Knowledge is limited regarding how long improvements in biomechanics remain after completion of a lower extremity injury prevention program. Purpose: To evaluate the effects an program on movement technique and peak vertical ground-reaction forces (VGRF) over time compared with standard warm-up (SWU) Study Design: Controlled laboratory study. Methods: A total 1104 incoming freshmen (age range, 17-22 years) at military academy United States volunteered to participate. Participants...
The Landing Error Scoring System (LESS) can be used to identify individuals with an elevated risk of lower extremity injury. limitation the LESS is that raters movement errors from video replay, which time-consuming and, therefore, may limit its use by clinicians. A markerless motion-capture system capable automating scoring, thereby removing this obstacle. To determine reliability automated for scoring LESS. Cross-sectional study. United States Military Academy. total 57 healthy, physically...
A greater knee valgus angle is a risk factor for lower extremity injuries. Visually observed medial displacement used as proxy motion during movement assessments in an attempt to identify individuals at heightened injury. The validity of indicator has yet be determined single-leg squat. This study compared three-dimensional and hip angles between participants who displayed (MKD group) squat those did not (control group). Participants completed five squats. An electromagnetic tracking system...
Females with history of anterior cruciate ligament (ACL) injury and subsequent reconstruction are at high risk for future ACL injury. Fatigue may influence the increased in females by altering lower extremity biomechanics postural control.Fatigue will promote control deficits associated injury.Descriptive laboratory study.Fourteen physically active (mean age, 19.64 ± 1.5 years; mean height, 163.52 6.18 cm; mass, 62.6 13.97 kg) volunteered this study. Postural were assessed surgical limb...
Preventive training programs (PTPs) can reduce injury rates and improve neuromuscular control sport performance. However, PTPs must be implemented correctly consistently over time for athletes to benefit. Coaches represent the best long-term option implementing PTPs. Youth are at optimal age developing good habits before maturation. Although frameworks have been proposed guide implementation efforts, little is known regarding feasibility real-world context of PTP youth level.To evaluate...
The purpose of this study was to examine associations between ankle dorsiflexion (ankle-DF) displacement and knee hip kinematics kinetics during a jump-landing task in females following anterior cruciate ligament reconstruction (ACLR). Females (n = 23) with history unilateral ACLR (≥ 6-months post-ACLR) underwent three-dimensional lower extremity biomechanical evaluation. Pearson Product Moment (r) correlations assessed ankle-DF kinematic kinetic variables. On the involved-limb, individuals...

This pilot study assessed the feasibility and combined effect of aerobic exercise (AE) mindfulness meditation (MM), compared with MM alone a control (CON) condition, on stress, anxiety, depression in high-stress college-based young adults. Thirty-two participants (84.4% F, 20.5 ± 2.7 years, 23.9 5.0 kg/m2) were randomized to four-week, AE + (n = 16), 10), or intervention 6). ANOVA revealed non-significant, but noteworthy group x time interactions (perceived stress: p 0.09;...
Lower extremity injuries have immediate and long-term consequences. movement assessments can assist with identifying individuals at greater injury risk guide prevention interventions. Movement identify similar characteristics evidence suggests large magnitude kinematic relationships exist between patterns observed across assessments; however, the of for electromyographic (EMG) measures remains largely unknown. This study examined lower EMG during jump landings single leg squats....
