AbstractThe modified Broström procedure (MBP) is an initial treatment for symptomatic chronic ankle instability (CAI) patients. This study aimed to compare the proprioception and neuromuscular control ability of both affected and unaffected ankles at the time of return to sports after MBP for patients with scores of normal controls. 75 individuals (40 who underwent MBP, 35 normal controls) participated. The dynamic balance test scores were significantly higher in the affected ankle of the patients than in the controls (1.5 ± 0.6° vs. 1.1 ± 0.4°, p < 0.003). The time to peak torque for dorsiflexion (60.8 ± 13.9 ms vs. 52.2 ± 17.5 ms, p < 0.022) and eversion (68.9 ± 19.1 ms vs. 59.3 ± 21.1 ms, p < 0.043) was significantly delayed in the affected ankle of the patients than in the controls. The dynamic balance test and time to peak torque in CAI patients remained significantly reduced at the time of return-to-sport after MBP. Clinicians and therapists should be aware of potential deficits in proprioception and neuromuscular control when determining the timing of return to sports after MBP.

Abstract Background: The modified Broström procedure (MBP) is an initial treatment in symptomatic chronic ankle instability (CAI) patients. However, there was a deficiency of studies regarding the recovery of proprioception and neuromuscular control at the timing of a return to sports after MBP. This study aimed to compare the proprioception and neuromuscular control of both affected and unaffected ankles at the timing of a return to sports after MBP in CAI patients with those of normal controls. Methods: Totally, 75 patients (40 who underwent MBP vs. 35 normal controls) participated. Proprioception and neuromuscular control were measured by postural stability and time to peak torque, respectively. Postural stability tests included static and dynamic balance and the star excursion balance test (SEBT). Static and dynamic balance were tested using a postural stabilometry system, and time to peak torque was measured using an isokinetic device. Results: The dynamic balance test was significantly higher in the affected ankle of the MBP group than in controls (1.5 ± 0.6 vs. 1.1 ± 0.4, p < 0.003). SEBT was significantly lower in the affected ankle of the MBP group compared to controls (anterior: 70.9±16.4 vs. 80.3±11.7, p < 0.006; posterior: 49.2 ± 10.0 vs. 62.2 ± 19.0, p < 0.000; lateral: 49.9 ± 12.7 vs. 57.3 ± 17.7, p < 0.040). Time to peak torque was significantly increased in the affected ankle of the MBP group compared to controls (dorsiflexion: 608.3 ± 139.4 vs.522.9 ± 175.8, p < 0.022; eversion: 689.1 ± 191.6 vs. 593.1 ± 211.2, p < 0.043). Conclusion: Dynamic balance, SEBT, and time to peak torque in CAI patients remained significantly reduced at the timing of a return to sports after MBP.

Proximal neuromuscular alterations are hypothesized to contribute to the patient- and disease-oriented deficits observed in CAI individuals. The objective was to compare the efficacy of two 4-week intervention programs with or without proximal joint exercises. Twenty-three individuals with CAI completed this single-blinded randomized controlled trial. Outcome measures included the Star Excursion Balance Test (SEBT) and the Foot and Ankle Ability Measure (FAAM). A time main effect was observed for the FAAM-ADL (p = .013), FAAM-Sport (p = .012), and posteromedial (p = .04) and posterolateral (p = .003) SEBT reach directions. No group main effect or time by group interaction was found. Four weeks of supervised rehabilitation improved self-reported function and dynamic balance in people with CAI.

Foot Orthosis

Background: Chronic ankle instability as a prevalent consequence of ankle sprain causes various impairments such as balance and postural control deficits. Foot orthoses are one of the common interventions for rehabilitation of patients with chronic ankle instability. Objectives: To investigate the effect of custom-molded foot orthoses with textured surfaces on dynamic balance of chronic ankle instability patients and to compare their effects with other types of foot orthoses. Study design: This is a repeated measure design. Methods: A total of 30 participants were recruited based on the guideline introduced by the International Ankle Consortium. The effect of prefabricated, custom-molded, and custom-molded with textured surface foot orthoses was evaluated on dynamic balance by the Star Excursion Balance Test. Normalized reach distances in anteromedial, medial, and posteromedial directions of the test were computed to be used for statistical analysis. Results: The foot orthoses increased reach distances compared to the no-orthosis conditions in all three directions. The custom-molded with textured surface foot orthosis has significant differences compared with prefabricated foot orthosis ( p = 0.001) in all measured directions and with custom-molded foot orthosis ( p < 0.01) in medial and posteromedial directions. Conclusion: Foot orthoses improve reach distances in patients with chronic ankle instability. Custom-molded with textured surface foot orthosis has a more pronounced effect compared with other foot orthoses. Clinical relevance The custom-molded foot orthosis with textured surface could be an effective device to improve dynamic balance in chronic ankle instability (CAI) patients. It may be considered as an efficient intervention to reduce ankle sprain recurrence in these individuals, although further research should be conducted.

Base Of Support

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.

Category: Sports Introduction/Purpose: Although the peroneal muscle is known to be a major dynamic lateral stabilizer of the ankle, few informations are available regarding the changes of muscle strength and relationship with the outcomes after lateral ligaments repair surgery. The purpose of this study was to identify the effects of peroneal strength on the validated functional outcome measures after the modified Broström procedure(MBP) for chronic ankle instability. Methods: Forty-one patients (41 ankles) underwent MBP using suture anchors were eligible and followed up to 2 years postoperatively. Functional evaluation consisted of the Foot and Ankle Outcome Score(FAOS), Foot and Ankle Ability Measure(FAAM). The changes of peroneal strength were evaluated using isokinetic dynamometer. Differences in the functional outcomes between the 3 groups divided according to recovery rate of peroneal strength were analysed. Results: Peak torque and total work for eversion in 60º/sec angular velocity significantly improved from a mean 8.1 Nm, 5.2 Nm preoperatively to 11.4 Nm, 6.9 Nm at postoperative 2 years, respectively (P < .001, P = .038). Deficit ratio of peak torque for eversion significantly improved from a mean 38.6% to 17.4%, and a significant side to side difference was found (P = .011). There were no significant differences in FAOS, FAAM, and measurements of stress radiograph between the 3 groups. Conclusion: Although restoration of peroneal strength postoperatively was about 82.6% of unaffected ankle, patient-reported function in daily and sport activities were satisfactorily improved. Postoperative isokinetic strength of the peroneus demonstrated no statistically significant effects on the functional outcomes after MBP.

The prevention of recurrent ankle sprain and functional ankle instability in soccer players is essential. This study clarified hip joint mobility and dynamic balance ability in soccer players with functional ankle instability. This case–control study included 17 male college soccer players. All participants were assessed using the Cumberland Ankle Instability Tool and were divided into chronic ankle instability (CAI) and non-CAI groups for each of their dominant and nondominant legs. Bilateral passive hip range of motion (ROM) was assessed and the modified Star Excursion Balance Test (mSEBT) was measured for each leg. In the dominant leg, the reach in the posterolateral direction in the CAI group was significantly less than that in the non-CAI group. Hip internal rotation angles in the dominant leg in the CAI group were greater than those in the non-CAI group; however, no significant correlations with the three directions of mSEBT were observed. In the nondominant leg, mSEBT and hip ROMs did not show any significant differences between groups. The dominant leg in soccer players with CAI had poor dynamic balance ability while reaching posterolaterally. However, acquiring hip flexibility may not be necessary to improve the dynamic balance ability. These findings may help develop future research.

Category: Sports Introduction/Purpose: To (1) describe muscle strength and postural stability in patients with chronic lateral ankle instability, and (2) analyze the correlation between weakness of muscle strength and deficits of postural stability Methods: Results of preoperative isokinetic and balance tests in 203 patients whose contralateral ankle was normal were retrospectively reviewed. Isokinetic peak torque values of eversion and inversion at 2 angular velocities (30°/s, 120°/s) were measured in injured and normal ankles. In balance test, the percent differences of 3 actual scores (Overall, Anterior-Posterior, and Medial-Lateral) between injured and normal ankles were calculated. Additional statistical analyses were performed to describe weakness of muscle strength, deficits of postural stability, and their correlation. Results: There were significant differences in 4 peak torque values and 4 relative peak torque values (peak torque/body weight) between injured and normal ankles. Eight values were significantly lower in injured ankles. Weakness was severe during inversion and at 30°/s. In balance test, 49 subjects (24.1%) had significant deficits in postural stability; the results in 109 subjects (53.7%) were favorable. There was no strong association between weakness of muscle strength and deficits of postural stability. Conclusion: Considering correlation between weakness of muscle strength and deficits of postural stability, strength measurement alone is insufficient in evaluating preoperative functional ability, and other functional test such as postural stability test is required. In addition, the results of this study may provide further evidence for rehabilitation program consisting of proprioceptive training as well as muscle strengthening.

BACKGROUND: Dynamic balance is an essential factor for efficient pitching by baseball pitchers. OBJECTIVE: To compare distances reached and lower-extremity muscle activity during the star excursion balance test (SEBT) in baseball pitchers and healthy young adults. METHODS: Nineteen baseball pitchers (BPG) and 20 healthy adults (HAG) were recruited. Surface EMG was used to measure the activity of vastus medialis (VM), vastus lateralis (VL), tibialis anterior, and lateral gastrocnemius. RESULTS: The BPG exhibited greater dynamic balance than in the HAG (p< 0.05) in the posteromedial (PM) and posterolateral (PL) directions. For the PM and PL directions, significantly greater muscle activity of VM and VL was found in the BPG than in the HAG (p< 0.05). CONCLUSION: SEBT performance is characterized by high-level VM and VL muscle activities. Neuromuscular control of knee extensors, such as the VM and VL of pitchers, might affect the dynamic balance measured by the SEBT.
