“…In the last two decades, numerous studies have been conducted to identify the mechanisms of CAI, substantially studying a single component of sensorimotor impairments (eg, strength, proprioception, postural control, etc) . However, related to common mechanisms of LAS, the injury frequently occurs during jumping, landing, and cutting maneuvers . Because of this, results of most previous studies primarily examining a static measure of sensorimotor impairments may not fully provide dynamic characteristics of altered movement strategies during functional tasks.…”

“…Lateral ankle sprains (LAS) are the most common lower-extremity injury during sport activities. 1 It has been reported that LAS could be associated with reduced proprioception (eg, joint position and force sense errors) 2 and diminished muscular strength and activation (eg, amplitude, timing, and recruitment). 3 Persistent sensorimotor deficits may lead to reorganization of sensorimotor processing in the central nervous system, resulting in altered feedforward motor control following initial and/or recurrent LAS.…”

Centrally mediated changes in sensorimotor function have been reported in patients with chronic ankle instability (CAI). However, little is known regarding supraspinal/spinal adaptations during lower‐extremity dynamic movement during a multiplanar, single‐leg landing/cutting task. The purpose of this study was to investigate the effect of CAI on landing/cutting neuromechanics, including lower‐extremity kinematic, electromyography (EMG) activation, and ground reaction force (GRF) characteristics. One hundred CAI patients and 100 matched healthy controls performed five trials of a jump landing/cutting task. Sagittal‐ and frontal‐plane ankle, knee and hip kinematics, EMG activation in eight lower‐extremity muscles, and 3D GRF were collected during jump landing/cutting. Functional analyses of variance (FANOVA) were used to evaluate between‐group differences for dependent variables throughout the entire ground contact of the task. Relative to the control group, the CAI group revealed (a) reduced dorsiflexion, increased knee and hip flexion angles, (b) increased inversion and hip adduction angles, (c) increased EMG activation of medial gastrocnemius, peroneus longus, adductor longus, vastus lateralis, gluteus medius, and gluteus maximus, and (d) increased posterior and vertical GRF during initial landing, and reduced medial, posterior, and vertical GRF during mid‐landing and mid‐cutting. CAI patients demonstrated alterations in landing/cutting movement strategies as demonstrated by a higher susceptibility of foot placement for lateral ankle sprains, and more flexed positions of the knee and hip with higher EMG activation of knee and hip extensors to modulate GRF to compensate for the unstable ankle. This apparent compensation may be due to mechanical (limited dorsiflexion angle) and/or sensorimotor deficits in the ankle.

“…For example, preventative measures such as prophylactic ankle supports and postural control training are viable options for LAS prevention, 31,32 and perhaps may be particularly valuable for taller athletes and those with a previous ankle sprain. As a LAS in collegiate women's soccer players occurs through a variety of mechanisms (~35% player contact, ~27% non-contact, ~25% surface contact, ~13% other), 33 postural control training likely should be diversified to include static and dynamic balance exercises, dynamic stability following a landing or cutting task, and external perturbations. Future studies should examine women's soccer players.…”

Background: Women's soccer has among the highest injury rates in collegiate sports, and lateral ankle sprains (LAS) are among the most commonly occurring injuries in that athletic population. However, no established LAS prediction model exists for collegiate women's soccer players.The purpose of this study was to develop a prediction model for acute LAS injuries in collegiate women's soccer players utilizing previous ankle sprain history, height, mass, and BMI as potential predictors.The authors' hypothesized that collegiate women's soccer players with greater height, mass, and body mass index (BMI), as well as a previous history of ankle sprain would have greater odds of sustaining a LAS.Study Design: Prospective cohort study.Methods: Forty-three NCAA Division I women's soccer players ' (19.7±1.1yrs, 166.8±3.7cm, 60.8±4.4kg) height, mass, and BMI were measured one week before beginning preseason practices. Additionally, participants reported whether or not they had sustained a previous ankle sprain. The team athletic trainer tracked LASs over the competitive season. Independent t-tests, binary logistic regression analyses, receiver operating characteristic (ROC) curves, and diagnostic statistics assessed the ability of the variables to differentiate between those that did and did not sustain a LAS. Results:Participants that sustained a LAS (n=8) were significantly taller than those that did not sustain a LAS (n=35) (t 41 =-2. 87, p=0.01, d=0.83[0.03,1.60] have demonstrated usefulness in LAS prediction models, 18-23 likely due to their potential influence on LAS mechanisms of injury. Typically, a LAS is sustained when excessive ankle plantar flexion, subtalar inversion, and foot internal rotation are present while decelerating during a functional task. [24][25][26][27] These combined movement patterns result in the center of pressure (COP) moving laterally on the plantar aspect of the foot, as well as medially relative to the ankle joint axis of rotation. In this position, an external load can create an external supination moment at the ankle. Greater body mass index (BMI), calculated from height and mass, likely increases the body's moments of inertia and reduces an individual's ability to resist external forces. 22 Due to the potential influence on injury occurrence and simplicity of their measurement, anthropometrics are viable predictor variables for any injury prediction analysis. No previous investigators have developed a model of LAS risk for collegiate women's soccer players specifically, but anthropometrics may possess potential injury prediction value for that population. Therefore, the purpose of this study was to develop a prediction model for acute LAS injuries in collegiate women's soccer players utilizing previous ankle sprain history, height, mass, and BMI as potential predictors. The primary hypothesis was that athletes with a previous ankle sprain history, greater height, mass, and BMI would have greater odds of sustaining a LAS.

“…Ankle sprains are very common sports injuries but can also happen during daily activities such as walking or even getting out of bed 1, 2 . Patients with inversion ankle sprains constitute a large percentage of these injuries, and occur with an incidence of one sprain per 10,000 people per day 3, 4 .…”

Distal tibiofibular syndesmosis (DTS) has wide anatomic variability in depth of incisura fibularis and shape of tibial tubercles. We designed a 3-year prospective cohort study of 300 young physical training soldiers in an Army Physical Fitness School. Ankle computed tomography (CT) scans showed that 56% of the incisura fibularis were a “C” shape, 25% were a “1” shape, and 19% were a “Г” shape. Furthermore, we invited a randomly selected subcohort of 6 participants in each shape of DTS to undergo a three-dimensional (3D) laser scanning. The “1” shape group showed widest displacement range of the DTS in the y-axis, along with the range of motion (ROM) on the position more than 20° of the ankle dorsiflexion, inversion and eversion. During the 3-year study period, 23 participants experienced recurrent lateral ankle sprains. 7 cases of the incisura fibularis were “C” shape, 13 cases were “1” shape, and 3 cases were “Г” shape. The “1” shape showed highest risk among the three shapes in incident recurrent lateral ankle sprains. We propose that it is possible to classify shapes of DTS according to the shapes of incisura fibularis, and people with “1” shape may have more risk of recurrent lateral ankle sprains.

The Epidemiology of Lateral Ligament Complex Ankle Sprains in National Collegiate Athletic Association Sports

Abstract: LLC sprains were the most commonly reported injury diagnosis among United States collegiate student-athletes. Continued examination of interventions that aim to reduce the incidence, severity, and recurrence of LLC sprains, specifically in women, is warranted.
