Abstract Purpose Lateral ankle sprains are one of the most prevalent musculoskeletal injuries, with one of the highest recurrence rates. One in five people develops chronic ankle instability (CAI) after a lateral ankle sprain. CAI is mainly described as a subjective phenomenon, but is associated with recurrent symptoms, reduced dynamic stability, and reduced physical activity and quality of life. Understanding the relationship between perception of stability and effect on performance for people with CAI could inform rehabilitative strategies in clinical practice. This study aimed to investigate the relationship between the perception of stability and objective performance of dynamic stability this population. Methods This study is a sub-analysis of data from four separate studies in Australia and the United Kingdom. Participants were screened and categorised as a CAI, coper, or healthy participant. Each participant completed the Star Excursion Balance Test (SEBT) and Cumberland ankle instability tool (CAIT). Distances reached in the anterior, posterior-medial, and posterior-lateral directions, and average, of the SEBT were analysed. Results Data from 95 participants with CAI, 45 copers, and 101 healthy participants was analysed. There was a significant moderate correlation between CAIT score and SEBT reach distance in all directions for the CAI group (p < 0.001). For copers, there was small significant correlation in the posterior-lateral direction (p < 0.05). Conclusion This study highlights the discrepancies between the perception of stability and objective dynamic stability, and reinforces the importance of using both types of measures for continual assessment in practice to optimise selecting rehabilitative strategies.

Given the prevalence of lateral ankle sprains during physical activity and the high rate of reinjury and chronic ankle instability, clinicians should be cognizant of the need to expand the evaluation of ankle instability beyond the acute time point. Physical assessments of the injured ankle should be similar, regardless of whether this is the initial lateral ankle sprain or the patient has experienced multiple sprains. To this point, a thorough injury history of the affected ankle provides important information during the clinical examination. The physical examination should assess the talocrural and subtalar joints, and clinicians should be aware of efficacious diagnostic tools that provide information about the status of injured structures. As patients progress into the subacute and return-to-activity phases after injury, comprehensive assessments of lateral ankle-complex instability will identify any disease and patient-oriented outcome deficits that resemble chronic ankle instability, which should be addressed with appropriate interventions to minimize the risk of developing long-term, recurrent ankle instability.

Context: The Dynamic Leap Balance Test (DLBT) is a new dynamic balance task that requires serial changes in base of support with alternating limb support and recovery of dynamic stability, as compared with the Y modification of the Star Excursion Balance Test (Y-SEBT), which assesses dynamic stability over an unchanging base of support. Objectives: To assess the dynamic balance performance in 2 different types of dynamic balance tasks, the DLBT and the SEBT, in subjects with unilateral chronic ankle instability (CAI) when compared with matched controls. The authors hypothesized that the DLBT score would significantly differ between the CAI involved and uninvolved limbs (contralateral and healthy matched) and demonstrate a modest (r = .50) association with the SEBT scores. Design: Case-control. Setting: Controlled laboratory. Participants: A total of 36 physically active adults, 18 with history of unilateral CAI and 18 without history of ankle injury, were enrolled in the study. CAI subjects were identified using the Identification of Functional Ankle Instability questionnaire. Interventions: The DLBT and the SEBT were performed in a randomized order on a randomly selected limb in CAI and healthy subjects. Main Outcome Measures: Time taken to complete the DLBT and the reach distances performed on the SEBT were compared between the CAI and the healthy subjects. Results: There were no statistically significant differences (P < .05) in SEBT reach distances between groups. The DLBT time was greater (P < .01) for unstable ankles compared with the stable ankle. The authors found no correlation (P > .05) between DLBT time and any of the SEBT reach distances suggesting that the DLBT provides unique information in the assessment of patients with CAI. Conclusion: The DLBT challenges the ability to maintain postural control in CAI subjects differently than the SEBT. There is a need of more dynamic balance assessment tools that are functional and clinically relevant.

Lateral Ankle Ligaments

Ankle sprains are common injuries involving the lateral ankle ligaments and affect athletes of all levels. Most patients heal uneventfully, but those with symptoms persisting past 3 months should be evaluated for chronic ankle instability and its associated conditions as well as for the presence of varus malalignment. Chronic ankle instability is initially treated nonoperatively, with surgical management reserved for those who have failed to improve after 3 to 6 months of bracing and functional rehabilitation. Anatomic repair using a modification of the Broström procedure is the preferred technique for initial surgery. Anatomic reconstruction with tendon graft should be considered when repair is not possible, as it maintains physiological joint kinematics. Nonanatomic reconstructions are seldom indicated. Arthroscopic repair or reconstruction of the lateral ankle ligaments is a promising new technique with results similar to those of open surgery.

Gait Kinematics

Context: Chronic ankle instability is characterized by repetitive lateral ankle sprains. Prophylactic ankle taping is a common intervention used to reduce the risk of ankle sprains. However, little research has been conducted to evaluate the effect ankle taping has on gait kinematics. Objective: To investigate the effect of taping on ankle and knee kinematics during walking and jogging in participants with chronic ankle instability. Design: Controlled laboratory study. Setting: Motion analysis laboratory. Patients or Participants: A total of 15 individuals (8 men, 7 women; age = 26.9 ± 6.8 years, height = 171.7 ± 6.3 cm, mass = 73.5 ± 10.7 kg) with self-reported chronic ankle instability volunteered. They had an average of 5.3 ± 3.1 incidences of ankle sprain. Intervention(s): Participants walked and jogged in shoes on a treadmill while untaped and taped. The tape technique was a traditional preventive taping procedure. Conditions were randomized. Main Outcome Measure(s): Frontal-plane and sagittal-plane ankle and sagittal-plane knee kinematics were recorded throughout the entire gait cycle. Group means and 90% confidence intervals were calculated, plotted, and inspected for percentages of the gait cycle in which the confidence intervals did not overlap. Results: During walking, participants were less plantar flexed from 64% to 69% of the gait cycle (mean difference = 5.73° ± 0.54°) and less inverted from 51% to 61% (mean difference = 4.34° ± 0.65°) and 76% to 81% (mean difference = 5.55° ± 0.54°) of the gait cycle when taped. During jogging, participants were less dorsiflexed from 12% to 21% (mean difference = 4.91° ± 0.18°) and less inverted from 47% to 58% (mean difference = 6.52° ± 0.12°) of the gait cycle when taped. No sagittal-plane knee kinematic differences were found. Conclusions: In those with chronic ankle instability, taping resulted in a more neutral ankle position during walking and jogging in shoes on a treadmill. This change in foot positioning and the mechanical properties of the tape may explain the protective aspect of taping in preventing lateral ankle sprains.

Context:  One of the major concerns after an acute lateral ankle sprain is the potential for development of chronic ankle instability (CAI). The existing research has determined that clinician-delivered plantar massage improves postural control in those with CAI. However, the effectiveness of self-administered treatments and the underlying cause of any improvements remain unclear. Objectives:  To determine (1) the effectiveness of a self-administered plantar-massage treatment in those with CAI and (2) whether the postural-control improvements were due to the stimulation of the plantar cutaneous receptors. Design:  Crossover study. Setting:  University setting. Patients or Other Participants:  A total of 20 physically active individuals (6 men and 14 women) with self-reported CAI. Intervention(s):  All participants completed 3 test sessions involving 3 treatments: a clinician-delivered manual plantar massage, a patient-delivered self-massage with a ball, and a clinician-delivered sensory brush massage. Main Outcome Measure(s):  Postural control was assessed using single-legged balance with eyes open and the Star Excursion Balance Test. Results:  Static postural control improved (P ≤ .014) after each of the interventions. However, no changes in dynamic postural control after any of the interventions were observed (P &gt; .05). No differences were observed between a clinician-delivered manual plantar massage and either a patient-delivered self-massage with a ball or a clinician-delivered sensory brush massage in any postural-control outcome. Conclusions:  In those with CAI, single 5-minute sessions of traditional plantar massage, self-administered massage, and sensory brush massage each resulted in comparable static postural-control improvements. The results also provide empirical evidence suggesting that the mechanism for the postural-control improvements is the stimulation of the plantar cutaneous receptors.

Clinical Questions

Abstract Objective: To answer the following clinical questions: (1) Is poor postural control associated with increased risk of a lateral ankle sprain? (2) Is postural control adversely affected after acute lateral ankle sprain? (3) Is postural control adversely affected in those with chronic ankle instability? Data Sources: PubMed and CINAHL entries from 1966 through October 2006 were searched using the terms ankle sprain, ankle instability, balance, chronic ankle instability, functional ankle instability, postural control, and postural sway. Study Selection: Only studies assessing postural control measures in participants on a stable force plate performing the modified Romberg test were included. To be included, a study had to address at least 1 of the 3 clinical questions stated above and provide adequate results for calculation of effect sizes or odds ratios where applicable. Data Extraction: We calculated odds ratios with 95% confidence intervals for studies assessing postural control as a risk factor for lateral ankle sprains. Effect sizes were estimated with the Cohen d and associated 95% confidence intervals for comparisons of postural control performance between healthy and injured groups, or healthy and injured limbs, respectively. Data Synthesis: Poor postural control is most likely associated with an increased risk of sustaining an acute ankle sprain. Postural control is impaired after acute lateral ankle sprain, with deficits identified in both the injured and uninjured sides compared with controls. Although chronic ankle instability has been purported to be associated with altered postural control, these impairments have not been detected consistently with the use of traditional instrumented measures. Conclusions: Instrumented postural control testing on stable force plates is better at identifying deficits that are associated with an increased risk of ankle sprain and that occur after acute ankle sprains than at detecting deficits related to chronic ankle instability.

Context:Chronic ankle instability (CAI) describes the residual symptoms present after repetitive ankle sprains. Current rehabilitation programs in the high school population focus on a multistation approach or general lower-extremity injury-prevention program. Specific rehabilitation techniques for CAI have not been established.Objective:To determine the effectiveness of a 4-wk biomechanical ankle platform system (BAPS) board protocol on the balance of high school athletes with CAI.Design:Randomized control trial.Setting:Athletic training facility.Patients:Twenty-two high school athletes with “giving way” and a history of ankle sprains (ie, CAI) were randomized into a rehabilitation (REH) (166.23 ± 0.93 cm, 67.0 ± 9.47 kg, 16.45 ± 0.93 y) or control (CON) (173.86 ± 8.88 cm, 84.51 ± 21.28 kg, 16.55 ± 1.29 y) group.Interventions:After baseline measures, the REH group completed a progressive BAPS rehabilitation program (3 times/wk for 4 wk), whereas the CON group had no intervention. Each session consisted of 5 trials of clockwise/counterclockwise rotations changing direction every 10 s during each 40-s trial. After 4 wk, baseline measurements were repeated.Main Outcome Measures:Dependent measures included longest time (time-in-balance test), average number of errors (foot lift test), average reach distance (cm) normalized to leg length for each reach direction (Star Excursion Balance Test [SEBT]), and fastest time (side hop test [SHT]).Results:Significant group-by-time interactions were found for TIB (F1,20 = 9.89, P = .005), FLT (F1,20 = 41.18, P < .001), SEBT-anteromedial (F1,20 = 5.34, P = .032), SEBT-medial (F1,20 = 7.51, P = .013), SEBT-posteromedial (F1,20 = 12.84, P = .002), and SHT (F1,20 = 7.50, P = .013). Post hoc testing showed that the REH group improved performance on all measures at posttest, whereas the CON group did not.Conclusion:A 4-wk BAPS rehabilitation protocol improved balance in high school athletes suffering from CAI. These results can allow clinicians to rehabilitate in a focused manner by using 1 rehabilitation tool that allows benefits to be accomplished in a shorter time.

Injury Causation

Lateral ankle sprains (LASs) are a common injury sustained by individuals who participate in recreational physical activities and sports. After an LAS, a large proportion of individuals develop long-term symptoms, which contribute to the development of chronic ankle instability (CAI). Due to the prevalence of LASs and the propensity to develop CAI, collective efforts toward reducing the risk of sustaining these injuries should be a priority of the sports medicine and sports physiotherapy communities. The comprehensive injury-causation model was developed to illustrate the interaction of internal and external risk factors in the occurrence of the inciting injury. The ability to mitigate injury risk is contingent on a comprehensive understanding of risk factors for injury. The objective of this current concepts review is to use the comprehensive injury-causation model as a framework to illustrate the risk factors for LAS and CAI based on the literature.
