“…Many recent reviews and multifactorial studies have provided important information outlining that there are multiple potential contributing mechanical, neuromuscular, functional, and/or perceived deficits that may persist long after physiologic tissue healing times have elapsed and interventions have been completed following an acute ankle joint sprain. [23][24][25][26][27][28][29][30][31][32][33][34] Consistently, these reviews and multifactorial studies support the proposition that CAI is a multifaceted and complex condition, requiring further indepth interdisciplinary study.…”

“…Data from other multifactorial studies that have included measures of mechanical instability in CAI patients suggest that mechanical instability alone is not a consistent identifier of this pathology. 28,33 A recent advancement in the CAI literature has been the stratification of individuals based on structural and functional impairments associated with ankle instability. Multiple studies by Brown et al [44][45][46] compared sensorimotor and biomechanical measures between patients classified as having mechanical ankle instability, functional ankle instability, and copers (no measurable ankle instability or repeated injury).…”

“…Previous authors have considered mechanical instability as an explanatory factor for lingering ankle instability, but there has not been a definitive association of ankle laxity with CAI. [19][20][21]23,28,29,33,44,45 Hertel's 19 original model differentiated mechanical instability from functional instability. More recently, Hiller et al, 21 refining the model of categorizing CAI, suggest as many as 7 subgroups of individuals with CAI that likely provide better homogeneity in describing the pathology.…”

While research on chronic ankle instability (CAI) and awareness of its impact on society and health care systems has grown substantially in the last 2 decades, the inconsistency in participant or patient selection criteria across studies presents a potential obstacle to addressing the problem properly. This major gap within the literature limits the ability to generalize this evidence to the target patient population. Therefore, there is a need to provide standards for patient or participant selection criteria in research focused on CAI with justifications using the best available evidence. The International Ankle Consortium provides this position paper to present and discuss an endorsed set of selection criteria for patients with CAI based on the best available evidence to be used in future research and study designs. These recommendations will enhance the validity of research conducted in this clinical population with the end goal of bringing the research evidence to the clinician and patient.

“…The manifestations of functional instability include impairments in sensorimotor control [27,33], which have been previously quantified by means of static [18,26,35] and dynamic balance tasks [28]. The Star Excursion Balance Test (SEBT) is one of the most commonly utilised measures of dynamic balance in lateral ankle sprain populations, capably identifying those who are at an increased risk of sustaining an ankle sprain injury [4,30], who have a current acute lateral ankle sprain injury [7], who are proceeding along the recovery trajectory of this injury [6], and who develop the chronic sequalae of chronic ankle instability [2,13,14,16].…”

lateral ankle sprain copers, 1-year following a first-time lateral ankle sprain injury. AbstractPurpose: To quantify the dynamic balance deficits that characterize a group with chronic ankle instability compared to lateral ankle sprain copers and non-injured controls using kinematic and kinetic outcomes.Methods: Forty-two participants with chronic ankle instability and twenty-eight ankle sprain copers were initially recruited within 2-weeks of sustaining a first-time, acute lateral ankle sprain and required to attend our laboratory one-year following to complete the current studyprotocol. An additional group of non-injured individuals were also recruited to act as a control group. All participants completed the anterior, posterior-lateral and posterior-medial reach directions of the Star Excursion Balance Test. Sagittal plane kinematics of the lower extremity and associated fractal dimension of the center of pressure path were also acquired. Results:Participants with chronic ankle instability displayed poorer performance in the anterior, posterior-medial and posterior-lateral reach directions compared to controls bilaterally, and in the posterior-lateral direction compared to ankle sprain copers on their 'involved' limb only. These performance deficits in the posterior-lateral and posterior-medial directions were associated with reduced flexion and dorsiflexion displacements at the hip, knee and ankle at the point of maximum reach, and coincided with reduced complexity of the center of pressure path. Conclusion:In comparison to ankle sprain copers and controls, participants with chronic ankle instability were characterized by dynamic balance deficits as measured using the SEBT. This was attested to reduced sagittal plane motions at the hip, knee and ankle joints, and reduced capacity of the stance limb to avail of its supporting base. Level of evidence: Level III

Introduction: Participation in sport among university athletes in Malaysia has progressed right up to Olympic level. However, some of these athletes are prevented from competing due to injuries. Ankle injuries, in particular, are among the common types of injury. Even so, there is still lack of local data and research describing the incidence of ankle injuries. Objectives: To determine peroneus longus muscle activity in different taped ankles and positions among subjects with functional ankle instability (FAI). Methods: Twenty-three subjects with ankle instability (AJFAT score > 26) volunteered to take part in the study. The subjects were tested under three conditions; 1) no tape (NT), 2) Kinesio(r) tape (KT), and 3) rigid tape (RT). The subjects completed two postural stability tests, followed by a sudden inversion perturbation test with EMG, recording throughout the procedures. The EMG data were analyzed, filtered, full-wave rectified and normalized. The data were analyzed by analysis of variance (Independent T-test and ANOVA) to evaluate differences in peak muscle activation (mV) and peroneal latency (ms). Results: Peak muscle activation of the peroneus was activated more in the RT group during both the Static and Dynamic Stability Tests. Apart from that, there were no statistically significant differences. During sudden inversion perturbation, the RT group was the one that was most activated (p=0.001). Peroneal latency was even delayed in KT and RT during the three tests, and shorter in the NT group. There were significant differences during the Dynamic Stability Test, between the NT and KT groups (p=0.001) and between the NT, RT and KT groups (p=0.001). Conclusion: RT tape may enhance the peroneus longus response by maintaining a higher level of muscle activation, especially during dynamic movements and sudden inversion of the ankle, and may selectively benefit individuals with FAI. The KT ankle did not show superior effect to the NT ankle, and demonstrated minimal benefit when used in FAI. Also, its use may be more likely to cause reinjury to the ankle.
