Context: Although lateral ankle sprains are common in athletes and can lead to chronic ankle instability (CAI), strength-training rehabilitation protocols may improve the deficits often associated with CAI. Objective: To determine whether strength-training protocols affect strength, dynamic balance, functional performance, and perceived instability in individuals with CAI. Design: Randomized controlled trial. Setting: Athletic training research laboratory. Patients or Other Participants: A total of 39 individuals with CAI (17 men [44%], 22 women [56%]) participated in this study. Chronic ankle instability was determined by the Identification of Functional Ankle Instability Questionnaire, and participants were randomly assigned to a resistance-band–protocol group (n = 13 [33%] age = 19.7 ± 2.2 years, height = 172.9 ± 12.8 cm, weight = 69.1 ± 13.5 kg), a proprioceptive neuromuscular facilitation strength-protocol group (n = 13 [33%], age = 18.9 ± 1.3 years, height = 172.5 ± 5.9 cm, weight = 72.7 ± 14.6 kg), or a control group (n = 13 [33%], age = 20.5 ± 2.1 years, height = 175.2 ± 8.1 cm, weight = 70.2 ± 11.1 kg). Intervention(s): Both rehabilitation groups completed their protocols 3 times/wk for 6 weeks. The control group did not attend rehabilitation sessions. Main Outcome Measure(s): Before the interventions, participants were pretested by completing the figure-8 hop test for time, the triple-crossover hop test for distance, isometric strength tests (dorsiflexion, plantar flexion, inversion, and eversion), the Y-Balance test, and the visual analog scale for perceived ankle instability. Participants were again tested 6 weeks later. We conducted 2 separate, multivariate, repeated-measures analyses of variance, followed by univariate analyses on any significant findings. Results: The resistance-band protocol group improved in strength (dorsiflexion, inversion, and eversion) and on the visual analog scale (P < .05); the proprioceptive neuromuscular facilitation group improved in strength (inversion and eversion) and on the visual analog scale (P < .05) as well. No improvements were seen in the triple-crossover hop or the Y-Balance tests for either intervention group or in the control group for any dependent variable (P > .05). Conclusions: Although the resistance-band protocol is common in rehabilitation, the proprioceptive neuromuscular facilitation strength protocol is also an effective treatment to improve strength in individuals with CAI. Both protocols showed clinical benefits in strength and perceived instability. To improve functional outcomes, clinicians should consider using additional multiplanar and multijoint exercises.

Context: Lateral ankle sprains commonly occur in an athletic population and can lead to chronic ankle instability. Objective: To compare ankle strength measurements in athletes who have mechanical laxity and report functional instability after a history of unilateral ankle sprains. Design: Retrospective cohort. Setting: Athletic Training Research Lab. Participants: A total of 165 National Collegiate Athletic Association Division I athletes, 97 males and 68 females, with history of unilateral ankle sprains participated. Main Outcome Measures: Functional ankle instability was determined by Cumberland Ankle Instability Tool scores and mechanical ankle instability by the participant having both anterior and inversion/eversion laxity. Peak torque strength measures, concentric and eccentric, in 2 velocities were measured. Results: Of the 165 participants, 24 subjects had both anterior and inversion/eversion laxity and 74 self-reported functional ankle instability on their injured ankle. The mechanical ankle instability group presented with significantly lower plantar flexion concentric strength at 30°/s (139.7 [43.7] N·m) (P = .01) and eversion concentric strength at 120°/s (14.8 [5.3] N·m) (P = .03) than the contralateral, uninjured ankle (166.3 [56.8] N·m, 17.4 [6.2] N·m, respectively). Conclusion: College athletes who present with mechanical laxity on a previously injured ankle exhibit plantar flexion and eversion strength deficits between ankles.

Abstract Objective Strength training as a form of exercise therapy has long been used to maintain or promote strength, but its effectiveness as a treatment intervention in chronic ankle instability is not fully understood. The purpose of this study was to evaluate the effects of strength training compared to no exercise and neuromuscular control training on balance and self-reported function in people with chronic ankle instability (CAI). Methods Eight databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, PEDro, CNKI, and WanFang) were searched in June 2020. Randomized controlled trials involving strength training conducted on individuals with CAI were included. Data were extracted by 2 independent reviewers using a standardized form. Methodological quality and risk of bias were assessed by using the PEDro scale. In addition, the evaluation system (Grading of Recommendations Assessment, Development and Evaluation [GRADE]) was used to determine the strength of evidence. A total of 554 studies were initially screened, resulting in a final selection of 11 RCTs involving 428 participants, and 8 RCTs were included in the final meta-analysis. Compared with no exercise, strength training demonstrated some benefits in the Star Excursion Balance Test (SEBT) (anterior: weighted mean difference [WMD] = 2.39, 95% CI = 0.60–4.18; posteromedial: WMD = 3.30, 95% CI = 0.24–6.35; posterolateral: WMD = 2.97, 95% CI = 0.37–5.57), but these intervention results did not reach the minimal detectable change values. Conclusions Available evidence showed that, compared with controls, strength training did not produce any minimal detectable changes on SEBT or Foot and Ankle Ability Measure scores in individuals with CAI. Clinicians should use strength training cautiously for improving balance and symptoms in CAI.

Aim: To identify the effects of balance and strength training on function, ankle instability and dynamic balance in people with chronic ankle instability. Method: The search was conducted on randomized controlled trials that investigated the effects of balance training or strength training in people with chronic ankle instability compared to a control group. Therefore, a systematic electronic search was performed until April 2021 in Pubmed/MEDLINE, Cochrane, and Embase databases. Moreover, an additional search was further performed checking the reference lists of the selected articles. The main outcomes were ankle instability, functionality, and dynamic balance. Finally, a qualitative and quantitative synthesis was performed. Results: Fifteen randomized controlled trials with 457 volunteers were included. Compared to regular exercise, balance training demonstrated to be more effective in terms of improving functionality (0.81 (0.48, 1.14)), ankle instability (0.77 (0.27, 1.26)), and dynamic balance (0.83 (0.57, 1.10)) outcomes. However, when compared to strength training, the effectiveness of balance training was only greater in terms of the functionality outcome (0.49 (0.06, 0.92)), since no differences were found for instability (0.43 (0.00, 0.85)) and dynamic balance (0.21 (−0.15, 0.58)). Conclusions: Based on fair-to-high quality evidence, balance training significantly improves functionality, instability, and dynamic balance outcomes in people with chronic ankle instability Moreover, results of the comparison between balance training versus strength training suggest that the former achieves greater benefits for functionality, but not for instability and dynamic balance. Systematic review registration number: CRD42021224179.

Context:  Functional rehabilitation may improve the deficits associated with chronic ankle instability (CAI). Objective:  To determine if balance- and strength-training protocols improve the balance, strength, and functional performance deficits associated with CAI. Design:  Randomized controlled clinical trial. Setting:  Athletic training research laboratory. Patients or Other Participants:  Participants were 39 volunteers with CAI, which was determined using the Identification of Functional Ankle Instability Questionnaire. They were randomly assigned to 1 of 3 groups: balance-training protocol (7 males, 6 females; age = 23.5 ± 6.5 years, height = 175.0 ± 8.5 cm, mass = 72.8 ± 10.9 kg), strength-training protocol (8 males, 5 females; age = 24.6 ± 7.7 years, height = 173.2 ± 9.0 cm, mass = 76.0 ± 16.2 kg), or control (6 males, 7 females; age = 24.8 ± 9.0 years, height = 175.5 ± 8.4 cm, mass = 79.1 ± 16.8 kg). Intervention(s):  Each group participated in a 20-minute session, 3 times per week, for 6 weeks. The control group completed a mild to moderately strenuous bicycle workout. Main Outcome Measure(s):  Participants completed baseline testing of eccentric and concentric isokinetic strength in each ankle direction (inversion, eversion, plantar flexion, and dorsiflexion) and the Balance Error Scoring System (BESS), Star Excursion Balance Test (SEBT), and side-hop functional performance test. The same variables were tested again at 6 weeks after the intervention. Two multivariate repeated-measures analyses of variance with follow-up univariate analyses were conducted. The α level was set a priori at .05. Results:  We observed time-by-group interactions in concentric (P = .02) and eccentric (P = .01) inversion, eccentric eversion (P = .01), concentric (P = .001) and eccentric (P = .03) plantar flexion, BESS (P = .01), SEBT (P = .02), and side hop (P = .004). With pairwise comparisons, we found improvements in the balance- and strength-training protocol groups in concentric and eccentric inversion and concentric and eccentric plantar flexion and the BESS, SEBT, and side hop (all P values = .001). Only the strength-training protocol group improved in eccentric eversion. The control group did not improve in any dependent variable. Conclusions:  Both training protocols improved strength, balance, and functional performance. More clinicians should incorporate hop-to-stabilization exercises into their rehabilitation protocols to improve the deficits associated with CAI.
