Context:Talocrural joint mobilizations are commonly used to address deficits associated with chronic ankle instability (CAI).Objective:Examine the immediate effects of talocrural joint traction in those with CAI.Design:Blinded, crossover.Setting:Laboratory.Participants:Twenty adults (14 females; age = 23.80 ± 4.02 y; height = 169.55 ± 12.38 cm; weight = 78.34 ± 16.32 kg) with self-reported CAI participated. Inclusion criteria consisted of a history of ≥1 ankle sprain, ≥2 episodes of giving way in the previous 3 mo, answering “yes” to ≥4 questions on the Ankle Instability Instrument, and ≤24 on the Cumberland Ankle Instability Tool.Intervention:Subjects participated in 3 sessions in which they received a single treatment session of sustained traction (ST), oscillatory traction (OT), or a sham condition in a randomized order. Interventions consisted of four 30-s sets of traction with 1 min of rest between sets. During ST and OT, the talus was distracted distally from the ankle mortise to the end-range of accessory motion. ST consisted of continuous distraction and OT involved 1-s oscillations between the mid and end-range of accessory motion. The sham condition consisted of physical contact without force application. Preintervention and postintervention measurements of weight-bearing dorsiflexion, dynamic balance, and static single-limb balance were collected.Main Outcome Measures:The independent variable was treatment (ST, OT, sham). The dependent variables included pre-to-posttreatment change scores for the WBLT (cm), normalized SEBTAR (%), and time-to-boundary (TTB) variables(s). Separate 1-way ANOVAs examined differences between treatments for each dependent variable. Alpha was set a priori at P < .05.Results:No significant treatment effects were identified for any variables.Conclusion:A single intervention of ST or OT did not produce significant changes in weight-bearing dorsiflexion range of motion or postural control in individuals with CAI. Future research should investigate the effects of repeated talocrural traction treatments and the effects of this technique when combined with other manual therapies.

Context:  Therapeutic modalities that stimulate sensory receptors around the foot-ankle complex improve chronic ankle instability (CAI)–associated impairments. However, not all patients have equal responses to these modalities. Identifying predictors of treatment success could improve clinician efficiency when treating patients with CAI. Objective:  To conduct a response analysis on existing data to identify predictors of improved self-reported function in patients with CAI. Design:  Secondary analysis of a randomized controlled clinical trial. Setting:  Sports medicine research laboratories. Patients or Other Participants:  Fifty-nine patients with CAI, which was defined in accordance with the International Ankle Consortium recommendations. Intervention(s):  Participants were randomized into 3 treatment groups (plantar massage [PM], ankle-joint mobilization [AJM], or calf stretching [CS]) that received six 5-minute treatments over 2 weeks. Main Outcome Measure(s):  Treatment success, defined as a patient exceeding the minimally clinically important difference of the Foot and Ankle Ability Measure–Sport (FAAM–S). Results:  Patients with ≤5 recurrent sprains and ≤82.73% on the Foot and Ankle Ability Measure had a 98% probability of having a meaningful FAAM–S improvement after AJM. As well, ≥5 balance errors demonstrated 98% probability of meaningful FAAM–S improvements from AJM. Patients &lt;22 years old and with ≤9.9 cm of dorsiflexion had a 99% probability of a meaningful FAAM–S improvement after PM. Also, those who made ≥2 single-limb–stance errors had a 98% probability of a meaningful FAAM–S improvement from PM. Patients with ≤53.1% on the FAAM–S had an 83% probability of a meaningful FAAM–S improvement after CS. Conclusions:  Each sensory-targeted ankle-rehabilitation strategy resulted in a unique combination of predictors of success for patients with CAI. Specific indicators of success with AJM were deficits in self-reported function, single-limb balance, and &lt;5 previous sprains. Age, weight-bearing–dorsiflexion restrictions, and single-limb balance deficits identified patients with CAI who will respond well to PM. Assessing self-reported sport-related function can identify CAI patients who will respond positively to CS.

Background. A semi-rigid brace or taping is often used to prevent giving-ways in the joint with chronic ankle instability (CAI). However, it remains unknown whether the application of a semi-rigid brace or taping modifies abnormal kinematics in CAI joints. The objective of this study was to determine if the application of a semi-rigid brace or taping of the ankle normalizes abnormal weight-bearing kinematics in CAI joints during ankle internal rotation in plantar flexion. Methods. A total of 14 male patients with unilateral CAI (mean age 21.1 ± 2.5 years) were enrolled. Three-dimensional bone models created from the computed tomography images were matched to the fluoroscopic images to compute the 6 degrees-of-freedom talocrural, subtalar, and ankle joint complex (AJC) kinematics for the healthy and contralateral CAI joints, as well as for CAI joints with a brace or taping. Selected outcome measures were talocrural anterior translation, talocrural internal rotation, and subtalar internal rotation. Results. There was no significant difference in talocrural anterior translation and internal rotation induced by applying either a semi-rigid brace or taping ( P > .05). For subtalar internal rotation, there was a tendency toward restoration of normal kinematics in CAI joints after applying a semi-rigid brace or taping. However, the difference was not significant ( P > .05). Discussion. Application of a semi-rigid brace or taping had limited effects on the CAI joint during weight-bearing ankle internal rotation in plantar flexion. Further studies using a variety of testing conditions should be conducted in the future. Levels of Evidence: Therapeutic, Level IV: Cross-Sectional Case Series

Abstract Background: Preliminary studies have reported differences in strength and functional performance between sexes for patients with anterior cruciate ligament injury or reconstruction. Similar sex differences may occur in chronic ankle instability (CAI) populations. Factors like hip abduction strength and functional performance may be contributors to sex differences in CAI populations, but their presence and magnitude is unclear. While decreased hip abductor strength, functional performance, and self-reported instability scores have all been shown in association with CAI, any sex difference in the relationship between these indicators is unclear. The study was to determine if sex differences are present in the relationship between these indicators in individuals with CAI.Methods：Thirty-two women and twenty-nine men with unilateral CAI took part. Hip abductor strength and functional performance were respectively assessed using a hand-held dynamometer and the figure-8-hop test. All 61 participants scored the Cumberland Ankle Instability Tool (CAIT) for self-reported ankle instability.Results: Normalized hip abductor strength and functional performance measures for females were lower than for males. The self-reported ankle instability CAIT score, where higher values represent less instability, was significantly and positively correlated with normalized hip abductor strength and functional performance on the affected side in females (all p < 0.01), but not in males (all p > 0.19).Conclusions: Sex differences were observed in the relationships of normalized hip abductor strength and functional performance to CAIT scores from the CAI, holding for females but not males, and suggesting that evaluation and rehabilitation strategies should be sex-specific.

ABSTRACT Introduction: Ankle sprains are recurrent injuries in basketball, hence more and more athletes are taping their ankles to promote joint stability, aiming at improving dynamic balance and, consequently, functional performance. Objective: To verify the effects of elastic and rigid athletic taping on the functional performance and level of comfort of basketball players with chronic ankle instability. Methods: Twenty-one athletes aged between 18 and 30 years (mean age 23.7 ± 3.2) with chronic ankle instability (CAI), verified using the Cumberland Ankle Instability Tool, were selected to take part in this study. The Star Excursion Balance Test (SEBT) and the Figure-of-8 hop test (F8) were applied unilaterally to assess functional performance, considering the ankle of greater instability in three situations: without athletic taping, with rigid athletic taping and with elastic athletic taping. A draw was held to determine the order in which the tests (held over a number of days) would be applied. A questionnaire was conducted to assess comfort on the same day the athletic tapes were applied. Results: There was no significant difference between the tests in any direction of the SEBT, but there was a significant difference in F8 between the rigid athletic taping x control and elastic athletic taping x control situations. In addition, the elastic athletic tape was considered significantly more comfortable than the rigid athletic tape. Conclusion: Athletic taping appears to effectively improve the dynamic balance and functional performance of athletes with CAI only in activities that cause considerable joint stress, as is the case in F8. Elastic athletic tape appears to be just as effective as rigid athletic tape in these situations, in addition to being a significantly more comfortable alternative. Levef of Evidence I; High quality randomized trial with statistically significant difference or no statistically significant difference but narrow confidence intervals.
