Chronic ankle instability (CAI) is a condition characterized by repetitive episodes of the ankle giving way and trauma as well as persistent symptoms such as pain, weakness, range of motion deficits, and reduced self-reported function. 1 The evolution and progression of CAI is thought to be due to

Both balance training and selected interventions meant to target sensory structures (STARS) have been shown to be effective at restoring deficits associated with chronic ankle instability (CAI). Clinicians often use multiple treatment modalities in patients with CAI. However, evidence for combined intervention effectiveness in CAI patients remains limited.
To determine if augmenting a balance-training protocol with STARS (BTS) results in greater improvements than balance training (BT) alone in those with CAI.
24 CAI participants (age 21.3 ± 2.0 y; height 169.8 ± 12.9 cm; mass 72.5 ± 22.2 kg) were randomized into 2 groups: BT and BTS.
Participants completed a 4-week progression-based balance-training protocol consisting of 3 20-min sessions per week. The experimental group also received a 5-min set of STARS treatments consisting of calf stretching, plantar massage, ankle joint mobilizations, and ankle joint traction before each balance-training session.
Main Outcome Measures:
Outcomes included self-assessed disability, Star Excursion Balance Test reach distance, and time-to-boundary calculated from static balance trials. All outcomes were assessed before, and 24-hours and 1-week after protocol completion. Self-assessed disability was also captured 1-month after the intervention.
No significant group differences were identified (P > .10). Both groups demonstrated improvements in all outcome categories after the interventions (P < .10), many of which were retained at 1-week posttest (P < .10). Although 90% CIs include zero, effect sizes favor BTS. Similarly, only the BTS group exceeded the minimal detectable change for time-to-boundary outcomes.
While statistically no more effective, exceeding minimal detectable change scores and favorable effect sizes suggest that a 4-week progressive BTS program may be more effective at improving self-assessed disability and postural control in CAI patients than balance training in isolation.

instability is a characterized by chronic symptoms, such as a recurring injury, feelings of the ankle “giving way,” and/or pain in the previously injured ankle. Other individuals who sustain lateral ankle sprain injury, that is, copers, recover in a manner in which recurring symptoms of chronic ankle

Clinical Scenario Lateral ankle sprains are the most commonly sustained sport-related injury. Approximately 40% of acute ankle sprain patients develop chronic ankle instability (CAI), which is characterized by residual ankle sprain symptoms, recurrent ankle sprains, and repetitive episodes of ankle

Chronic ankle instability (CAI) is a frequently reported residual pathology as a result of an initial ankle sprain event. 1 A prevalence study identified CAI in 23.4% of all high school and college athletes. 2 The high prevalence of CAI is caused by a multifactorial underlying mechanism and is

The article presents a focused review of the literature surrounding training methods for addressing the proprioceptive loss and subsequent balance problems that result from inversion ankle sprains.
The authors searched the MEDLINE and CINAHL databases for the period 1985 through December 2001 using the key words ankle, ankle sprain, and rehabilitation.
Any study investigating a rehabilitation or prevention program for the proprioceptive or balance aspects of ankle instability was included.
Key components of the training regimen used in each study are described, and major findings are summarized.
Based on the literature reviewed, there is evidence to suggest that training programs for individuals with ankle instability that include ankle-disk or wobble-board activities help improve single-leg-stance balance and might decrease the likelihood of future sprains.

Chronic ankle instability (CAI) is a prevalent lower-extremity musculoskeletal condition that manifests in approximately 40% of first-time lateral ankle sprain cases. 1 CAI is characterized by residual pain, weakness, and patient-reported episodes of the ankle “giving way” and reinjury. 1 CAI is
