Abstract
To compare the dynamic stability of lower extremities between Copers and individuals with chronic ankle instability (CAI) using clinician-oriented assessments (Y-balance test, YBT) and laboratory-oriented assessments (time to stabilization, TTS). 90 participants (Copers, 45; CAIs, 45) were recruited and measured by YBT and TTS to evaluate dynamic stability. The difference of dynamic stability between Copers and CAIs was examined using a two-factor MANOVA. Only for females in anterior direction, YBT scores for the AS side of Copers were significantly higher than that of CAIs. For males, the TTS of CAIs was significantly shorter than that of Copers in the anterior, lateral, and medial direction separately. For females, the TTS of CAIs is also significantly shorter than that of Copers in the anterior, lateral, and medial direction separately. There are opposite results when evaluating the dynamic stability difference between Copers and CAIs using YBT and TTS.

[PMID: 37705053 PMCID: PMC10498520 DOI: 10.1186/s13047-023-00662-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 08/28/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Functional ankle instability (FAI) is a common condition that affects individuals who have experienced previous ankle sprains. Textured insoles and elastic ankle braces have been previously used as interventions to improve stability in FAI patients. However, the optimal combination of these interventions has not been fully explored. The objective of this study was to investigate the effects of different types of textured insoles and elastic ankle braces on the dynamic stability of individuals diagnosed with FAI. METHODS The study involved 18 FAI patients who performed single-leg landing tasks with and without wearing an eight-band elastic ankle brace while wearing textured insoles with protrusion heights of 0 mm, 1 mm, and 2 mm. The dynamic posture stability index (DPSI) and its components in the anterior-posterior (APSI), mediolateral (MLSI) and vertical (VSI) directions were calculated from the ground reaction force collected from the Kistler force plate during the first three seconds of the landing tasks. RESULTS A significant interaction was found between textured insole type and ankle brace for DPSI (P = 0.026), APSI (P = 0.001), and VSI (P = 0.021). However, no significant interaction was observed for MLSI (P = 0.555). With elastic ankle braces, textured insoles with 1-mm protrusions significantly enhanced anterior-posterior, mediolateral, vertical, and overall stability compared to textured insoles with no and 2 mm protrusions (P < 0.05). Without elastic ankle braces, textured insoles with 1-mm protrusions significantly improved the anterior-posterior (P = 0.012) and overall stability (P = 0.014) of FAI patients compared to smooth insoles. CONCLUSIONS The combination of textured insoles with 1-mm protrusion heights and an elastic ankle brace could enhance the dynamic stability of individuals with FAI, potentially mitigating the risk of ankle sprains.

Seever TC, Mason J, Zech A. Chronic and Residual Effects of a Two-Week Foam Rolling Intervention on Ankle Flexibility and Dynamic Balance. Front Sports Act Living 2022; 4:799985. [PMID: 35243341 PMCID: PMC8886294 DOI: 10.3389/fspor.2022.799985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/20/2022] [Indexed: 11/26/2022] Open
Abstract
Background Foam rolling has been shown to acutely improve joint range of motion (ROM). However, limited knowledge exists on the chronic and residual effects. The primary purpose of this study was to examine the chronic and residual effects of a 2-week roller–massager intervention on ankle dorsiflexion ROM and dynamic balance. Methods Forty-two participants (24.3 ± 2.5 years, 33 males, 9 females) were randomly assigned to either roller-massage (RM) or control group (= no intervention). Ankle ROM was assessed with the weight-bearing lunge test (WBLT) and dynamic balance with the Y-Balance test for both limbs. The RM group was instructed to roll their calf muscles for three sets of 60 s per leg on 6 days a week over 2 weeks. Acute effects were measured during baseline testing for dorsiflexion ROM and dynamic balance immediately after foam rolling. Chronic and residual effects were measured 1 day and 7 days after the intervention period. Multivariate ANOVA was performed for post-hoc comparisons to determine acute, chronic, and residual effects. Results Significant acute and chronic foam rolling effects (p <0.05) were found for ankle dorsiflexion ROM. The chronic increase in ROM slightly decreased 7 days post-intervention but remained significantly above baseline (p < 0.05). Regarding dynamic balance, there were no acute but chronic (p < 0.05) and residual (p < 0.05) effects. Conclusion Using a roller–massager for a 2-week period chronically increases ROM and dynamic balance. These increases are still significant 7 days post-intervention emphasizing the sustainability of foam rolling effects.

Abstract
OBJECTIVE The purpose of this review with meta-analyses was to determine the dynamic reach differences 1) between chronic ankle instability (CAI) and uninjured individuals, 2) between the limbs of an individual with CAI, and 3) between the uninvolved CAI limb and the healthy control limb across all possible reach directions of the Star Excursion Balance Test (SEBT). METHODS PubMed, CINAHL, SPORTDiscus, and Scopus databases were searched up to October 2021. Data were extracted from the retained studies and underwent methodological quality assessment and meta-analysis using random-effect models. RESULTS After screening, 33 articles were included for the analyses. In all possible SEBT reach directions, the CAI group demonstrated significantly decreased normalized dynamic reach distances relative to the uninjured control group (SMDs: -0.66 to -0.48, p ≤ 0.05). Similarly, the involved CAI limb demonstrated significantly decreased normalized dynamic reach distances relative to the uninvolved CAI limb (SMDs: -0.61 to -0.33, p ≤ 0.05). However, no differences were noted between the uninvolved CAI limb and the healthy control limb (SMDs: -0.22 to 0.09, p ≥ 0.13). CONCLUSIONS Our findings were that the involved limb of those with CAI has dynamic postural deficits relative to (i) an uninjured control group and (ii) relative to their uninvolved limb. However, the uninvolved limb of the CAI group does not differ from an uninjured control group in any reach direction.

Abstract
This revised clinical practice guideline (CPG) addresses the distinct but related lower extremity impairments of those with a first-time lateral ankle sprain (LAS) and those with chronic ankle instability (CAI). Depending on many factors, impairments may continue following injury. While most individuals experience resolution of symptoms, complaints of instability may continue and are defined as CAI. The aims of the revision were to provide a concise summary of the contemporary evidence since publication of the original guideline and to develop new recommendations or revise previously published recommendations to support evidence-based practice.

Abstract
BACKGROUND Chronic ankle instability (CAI) is a frequent complication of ankle sprain that may be associated with long-term consequences. Although taping and bracing are common interventions that are widely used by clinicians and athletic trainers for patients with CAI, no studies have compared the effects of kinesiotaping and bracing on balance performance in these patients. The present study aimed to compare the effects of ankle kinesiotaping, a soft ankle orthosis, and a semirigid ankle orthosis on balance performance in patients with CAI. METHODS Sixty patients with CAI were randomly assigned to 4 groups that received kinesiotaping, a soft orthosis, a semirigid orthosis, or no treatment (control group). Dynamic and static balance were measured with the modified Star Excursion Balance Test, single leg hop test, and single leg stance test before and after a 4-week intervention period. RESULTS Significant between-group differences were seen in all evaluated outcomes (P ≤ .003). The lowest reach distances in all directions in the modified Star Excursion Balance Test were found in the control group, and these patients also had a significantly shorter measured distance in the single leg hop test, and more errors in the single leg stance test compared with the 3 intervention groups. No significant differences were found among the 3 intervention groups. CONCLUSION Use of kinesiotaping and a soft or a semirigid ankle brace for 4 weeks were all beneficial in improving static and dynamic balance in individuals with CAI. None of the interventions was superior to the other 2. LEVEL OF EVIDENCE Level I, randomized controlled trial.
