“…In a recent systematic review of the prevalence of CAI in sporting populations, Attenborough et al 115 indicated that CAI is a highly prevalent condition (>25%) in sports such as handball, basketball, soccer and volleyball. This has been confirmed in recent investigations of collegiate and high school athletes in which the prevalence of CAI was ∼25% in those athletes with a previous history of injury 116 117. Within the performing arts population, such as ballet, more than 50% of the dancers with a history of ankle sprain report CAI 118.…”

“…These trends are higher in athletic populations (at least 1 of 3)115 117 and among dancers (1 out of 2) 118. When examining the trends within the general public, individuals with chronic ankle problems report increased modification of functional activity and reduced overall health compared with their non-injured counterparts in the community.…”

Evidence review for the 2016 International Ankle Consortium consensus statement on the prevalence, impact and long-term consequences of lateral ankle sprains

Lateral ankle sprains (LASs) are the most prevalent musculoskeletal injury in physically active populations. They also have a high prevalence in the general population and pose a substantial healthcare burden. The recurrence rates of LASs are high, leading to a large percentage of patients with LAS developing chronic ankle instability. This chronicity is associated with decreased physical activity levels and quality of life and associates with increasing rates of post-traumatic ankle osteoarthritis, all of which generate financial costs that are larger than many have realised. The literature review that follows expands this paradigm and introduces emerging areas that should be prioritised for continued research, supporting a companion position statement paper that proposes recommendations for using this summary of information, and needs for specific future research.

“…1,2 Multiple definitions and models have been used to define CAI. 3,4 However, because of its multi-faceted and heterogeneous character, CAI has recently been defined by the International Ankle Consortium (IAC) as being a chronic condition including three major aspects: (1) a history of at least one significant ankle sprain, (2) a history of ankle joint 'giving way' and/or recurrent sprain, and/or 'feelings of instability', (3) a poor disability status according to specific questionnaires.…”

“…1 Chronic ankle instability is a complex injury caused by mechanical and functional insufficiencies, found after the resolution of an initial lateral ankle sprain, which can lead to repetitive sprains and instability of the ankle joint. 2 Typically, individuals with CAI report feelings of the ankle ''giving way'' during activity.…”

Context: Altered gait kinetics may increase the risk of longterm injuries in participants with chronic ankle instability (CAI). Vertical ground reaction forces (vGRFs) can provide insight into how body loading is altered.Objective: To compare the components of vGRFs while running in participants with or without CAI.Design: Cohort study. Setting: University biomechanics laboratory.Patients or Other Participants: Twenty-four experienced, college-aged runners. Groups were categorized by the presence (CAI group) or absence (control group) of CAI through selfreported questionnaires.Intervention(s): After a warm-up period, all participants ran on an instrumented treadmill for 5 minutes at 3.3 m/s. Data were collected during the last 30 seconds. Five continuous trials of heel-to-toe running were identified per participant and averaged for statistical analysis.Main Outcome Measure(s): The dependent variables were impact peak force (N/body weight [BW]), active peak force (N/ BW), time to impact peak force (milliseconds), time to active peak force (milliseconds), and average loading rate ([N/BW]/s).Results: A difference was found between groups (P ¼ .002). The CAI group had higher impact peak forces (P ¼ .001) and active peak forces (P ¼ .002) compared with the control group. The CAI group also had an increased loading rate (P ¼ .001) and a shorter time to reach the active peak force (P ¼ .001) compared with the control group. No difference was seen between groups in the time to reach the impact peak force (P ¼ .952).Conclusions: Participants with CAI produced altered vGRFs and loading rates while running. Altered loading rates could predispose individuals with CAI to stress-related injuries and repetitive sprains.Key Words: biomechanics, gait, kinetics, stress fractures Key PointsThe group with chronic ankle instability demonstrated greater vertical ground reaction forces and initial and active peak forces. Those with chronic ankle instability also had increased loading rates, which could make them vulnerable to stress injuries and sprains.
