Context: Strength deficits and decreased scores on generic, dimension-specific, and region-specific health-related quality of life (HRQL) PRO measures are commonly documented among individuals with chronic ankle instability (CAI). However, it is unknown if there is a relationship between hip strength and self-reported patient-reported outcome (PRO) scores. Objective: To compare isometric peak torque for hip-extension (H-EXT) and hip-abduction (H-ABD), as well as PRO scores between CAI, lateral ankle sprain copers (LAS copers), and uninjured controls (UC). The secondary purpose was to examine the relationship between isometric hip peak torque and PROs in participants with CAI. Design: Cross-sectional. Setting: Laboratory. Participants: Sixty-three individuals, 45 women (23.02 [3.83] y, 165.91 [7.55] cm, 67.28 [11.95] kg) and 18 men (26.28 [5.43] y, 179.28 [9.01] cm, 83.87 [13.26] kg), grouped as uninjured control (n = 26), LAS coper (n = 15), or CAI (n = 22). Main Outcome Measures: The Foot and Ankle Ability Measure was used to assess region-specific HRQL. The Fear Avoidance Beliefs Questionnaire was used to assess injury-related fear. The Disablement in Physically Active was used to assess global HRQL. Isometric peak torque was measured with a handheld dynamometer for H-EXT and H-ABD. Results: No group differences were observed for H-ABD (P = .34) or H-EXT (P = .35). The CAI group had significantly worse scores on all PROs compared with LAS coper (P < .001) and HC (P < .001). Moderate–weak correlations were found between H-ABD and Foot and Ankle Ability Measure—activities of daily living (P = .047; ρ = .392) and Foot and Ankle Ability Measure-Sport (P = .013; ρ = .482) and H- EXT and Fear Avoidance Beliefs Questionnaire-Work (P = .007; ρ = −.517). Conclusions: Individuals with CAI displayed lower HRQL based on worse scores on generic, dimension-specific, and region-specific PROs compared with LAS copers and uninjured controls. There were no significant between-group differences for H-EXT and H-ABD isometric peak torque production, but there was a moderate positive relationship between isometric H-ABD and self-reported ankle disability in individuals with CAI.

Context Individuals with chronic ankle instability (CAI) experience disease- and patient-oriented impairments that contribute to both immediate and long-term health detriments. Investigators have demonstrated the ability of targeted interventions to improve these impairments. However, the combined effects of a multimodal intervention on a multidimensional profile of health have not been evaluated. Objective To examine the effects of a 4-week rehabilitation program on disease- and patient-oriented impairments associated with CAI. Design Controlled laboratory study. Setting Laboratory. Patients or Other Participants Twenty adults (5 males, 15 females; age = 24.35 ± 6.95 years, height = 169.29 ± 10.10 cm, mass = 70.58 ± 12.90 kg) with self-reported CAI participated. Inclusion criteria were at least 1 previous ankle sprain, at least 2 episodes of “giving way” in the 3 months before the study, and a Cumberland Ankle Instability Tool score ≤24. Intervention(s) Individuals participated in 12 sessions over 4 weeks that consisted of ankle stretching and strengthening, balance training, and joint mobilizations. They also completed home ankle-strengthening and -stretching exercises daily. Main Outcome Measure(s) Dorsiflexion range of motion (weight-bearing–lunge test), isometric ankle strength (inversion, eversion, dorsiflexion, plantar flexion), isometric hip strength (abduction, adduction, flexion, extension), dynamic postural control (Y-Balance test), static postural control (eyes-open and -closed time to boundary in the anterior-posterior and medial-lateral directions), and patient-reported outcomes (Foot and Ankle Ability Measure–Activities of Daily Living and Foot and Ankle Ability Measure–Sport, modified Disablement in the Physically Active scale physical and mental summary components, and Fear-Avoidance Beliefs Questionnaire–Physical Activity and Fear-Avoidance Beliefs Questionnaire–Work) were assessed at 4 times (baseline, preintervention, postintervention, 2-week follow-up). Results Dorsiflexion range of motion, each direction of the Y-Balance test, 4-way ankle strength, hip-adduction and -extension strength, the Foot and Ankle Ability Measure–Activities of Daily Living score, the modified Disablement in the Physically Active scale–physical summary component score, and the Fear-Avoidance Beliefs Questionnaire–Physical Activity score were improved at postintervention (P &lt; .001; effect-size range = 0.72–1.73) and at the 2-week follow-up (P &lt; .001; effect-size range = 0.73–1.72) compared with preintervention. Hip-flexion strength was improved at postintervention compared with preintervention (P = .03; effect size = 0.61). Hip-abduction strength was improved at the 2-week follow-up compared with preintervention (P = .001; effect size = 0.96). Time to boundary in the anterior-posterior direction was increased at the 2-week follow-up compared with preintervention (P &lt; .04; effect-size range = 0.61–0.78) and postintervention (P &lt; .04) during the eyes-open condition. Conclusion A 4-week rehabilitation program improved a multidimensional profile of health in participants with CAI.

Context The accurate evaluation of self-reported changes in function throughout the rehabilitation process is important for determining patient progression. Currently, how a response shift (RS) may affect the accuracy of self-reported functional assessment in a population with chronic ankle instability (CAI) is unknown. Objective To examine the RS in individuals with CAI after a 4-week multimodal rehabilitation program. Design Controlled laboratory study. Setting Laboratory. Patients or Other Participants Twenty adults (5 men, 15 women; age = 24.35 ± 6.95 years, height = 169.29 ± 10.10 cm, mass = 70.58 ± 12.90 kg) with self-reported CAI participated. Inclusion criteria were at least 1 previous ankle sprain, at least 2 episodes of the ankle “giving way” in the 3 months before the study, and a score ≤24 on the Cumberland Ankle Instability Tool. Intervention(s) Individuals participated in 12 intervention sessions over 4 weeks and daily home ankle strengthening and stretching. Main Outcome Measure(s) Patient-reported outcomes (PROs) were assessed at 4 times (baseline, preintervention, postintervention, and 2-week follow-up). At the postintervention and 2-week follow-up, participants completed then-test assessments to measure RS. Then-test assessments are retrospective evaluations of perceived baseline function completed after an intervention. The PROs consisted of the Foot and Ankle Ability Measure-Activities of Daily Living and Sport subscales, the modified Disablement in the Physically Active scale physical and mental summary components, and the Fear-Avoidance Beliefs Questionnaire Physical Activity and Work subscales. We used repeated-measures analyses of variance to compare preintervention with then-test measurements. Individual-level RSs were examined by determining the number of participants who experienced preintervention to then-test differences that exceeded the calculated minimal detectable change. Results We did not identify an RS for any PRO (F &gt; 2.338, P &gt; .12), indicating no group-level differences between the preintervention and retrospective then-test assessments. Individual-level RS was most prominent in the Foot and Ankle Ability Measure-Sport subscale (n = 6, 30%) and the Fear-Avoidance Beliefs Questionnaire Physical Activity subscale (n = 9, 45%). Conclusions No group-level RS was identified for any PRO after a 4-week multimodal rehabilitation program in individuals with CAI. This finding indicates that traditional assessment of self-reported function was accurate for evaluating the short-term effects of rehabilitation in those with CAI. Low levels of individual-level RS were identified.

Context:  Assessing global, regional, and fear-of-reinjury outcomes in individuals with chronic ankle instability (CAI) is critical to understanding the effectiveness of clinical interventions. Objective:  To determine the improvement of patient-reported outcomes after balance- and strength-training and control protocols among participants with CAI. Design:  Randomized controlled clinical trial. Setting:  Athletic training research laboratory. Patients or Other Participants:  Thirty-nine volunteers with CAI who scored 11 or greater on the Identification of Functional Ankle Instability questionnaire 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 met for 20 minutes, 3 times each week, for 6 weeks. The control group completed a mild to moderately strenuous bicycle workout. Main Outcome Measure(s):  Global patient-reported outcomes, regional ankle function, and perceived instability were measured using the Disablement in the Physically Active Scale, the Fear-Avoidance Beliefs Questionnaire, the Foot and Ankle Ability Measure, and a visual analog scale for perceived instability. Participants completed the questionnaires at pretest and 6 weeks posttest. A multivariate repeated-measures analysis of variance with follow-up univariate analysis was conducted. The α level was set a priori at .05. Results:  No time-by-group interaction was found (P = .78, η2 = 0.09). However, we observed a main effect for time (P = .001, η2 = 0.49). Follow-up univariate analyses revealed differences between the pretest and posttest for the Disablement in the Physically Active Scale (P = .02, η2 = 0.15), Fear-Avoidance Beliefs Questionnaire (P = .001, η2 = 0.27), Foot and Ankle Ability Measure–Activities of Daily Living subscale (P = .003, η2 = 0.22), Foot and Ankle Ability Measure–Sport subscale (P = .001, η2 = 0.36), and visual analog scale (P = .008, η2 = 0.18). Conclusions:  Statistically, after the 6-week intervention, all groups improved in global and regional health-related quality of life. Clinicians should compare patient-reported outcomes with clinical measures to have a better understanding of progression during rehabilitation.

Context: Injury-related fear has recently been recognized to exist in ankle sprain populations. It is unclear, however, if injury-related fear levels differ between those who develop chronic ankle instability (CAI) and those who do not and the best tools for assessing these differences. Objective: The purpose of this study was to conduct a comprehensive systematic review investigating differences in injury-related fear between individuals with and without CAI. Evidence Acquisition: Relevant studies from CINAHL Plus with full text, PubMed, and SPORTDiscus through November 2020 were included. All studies used the Tampa Scale of Kinesiophobia, Fear-Avoidance Beliefs Questionnaire, or Athlete Fear Avoidance Questionnaire as either a descriptor or a main outcome and provided comparison data between a CAI group and ankle sprain copers (COP) or controls (CON). The authors independently assessed methodological quality using the modified Downs and Black Quality Index. Studies were then grouped by between-group comparisons including CAI and CON, CAI and COP, and COP and CON. The authors calculated Hedge g effect sizes and 95% confidence intervals to examine group differences. Evidence Synthesis: A total of 11 studies were included in this review. In total, 8 studies provided data for the CAI and CON comparison, 7 for CAI and COP comparisons, and 4 for COP and CON comparisons. Methodological quality scores ranged from 60.0% to 86.7%, with 2 high-, and 9 moderate-quality studies. Overall, the evidence suggests that physically active individuals with CAI report higher levels of injury-related fear when compared with both COP and CON. Although limited, ankle sprain COP do not seem to differ from CON. Conclusion: Available evidence emphasizes the importance of injury-related fear in individuals who develop chronicity after ankle sprain injury. The Fear-Avoidance Beliefs Questionnaire and Tampa Scale of Kinesiophobia are useful for the identification of injury-related fear in individuals after sustaining an ankle sprain and should be used to inform rehabilitation strategies and to monitor efficacy in fear reduction.

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 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. Conclusions: Although restoration of peroneal strength postoperatively was about 82.6% of the unaffected ankle, patient-reported function in daily and sport activities were satisfactorily improved. Postoperative isokinetic strength of the peroneals demonstrated no statistically significant effects on the functional outcomes after MBP. Level of Evidence: Level III, prospective comparative case series.

The study objective was to develop a shortened version of the Foot and Ankle Ability Measure (FAAM) for individuals with chronic ankle instability (CAI). Forty individuals with CAI completed the FAAM Activities of Daily Living and Sport subscales and the Short Form-12. Analyses were completed for item reduction followed by dimensionality, coverage redundancy, and internal consistency of a reduced-item instrument. Validity was examined through correlations with the original FAAM and Short Form-12. A 12-item FAAM was created which demonstrated strong internal consistency and convergent/divergent validity. The Quick-FAAM may provide an alternative patient-reported outcome for CAI which requires less administration time.

Context: Individuals with chronic ankle instability (CAI) have reported decreased global and regional function. Despite the identification of functional deficits in those with CAI, more research is required to determine the extent to which CAI influences the multidimensional profile of health-related quality of life. Objective: To determine whether global, regional, and psychological health-related outcomes differ between individuals with and without CAI. Design: Case-control study. Setting: Laboratory. Patients or Other Participants: Twenty-five participants with CAI (age = 21.9 ± 2.5 years, height = 170.8 ± 8.6 cm, mass = 69.8.0 ± 11.7 kg) were sex- and limb-matched to 25 healthy participants (age = 22.0 ± 2.1 years, height = 167.4 ± 9.1 cm, mass = 64.8 ± 11.2 kg). Main Outcome Measure(s): Both groups completed the Disablement in the Physically Active Scale, the Foot and Ankle Ability Measure (FAAM), the FAAM-Sport, the Tampa Scale of Kinesiophobia-11, and the Fear-Avoidance Beliefs Questionnaire. Dependent variables were scores on these instruments, and the independent variable was group. Results: Compared with healthy individuals, those with CAI reported decreased function on the Disablement in the Physically Active Scale, FAAM, and FAAM-Sport (P &lt; .001) and increased fear of reinjury on the Tampa Scale of Kinesiophobia-11 and Fear-Avoidance Beliefs Questionnaire (P &lt; .001). In the CAI group, the FAAM and FAAM-Sport demonstrated a significant relationship (r = 0.774, P &lt; .01). Conclusions: Individuals with CAI reported decreased function and increased fear of reinjury compared with healthy control participants. Also, within the CAI group, there was a strong relationship between FAAM and FAAM-Sport scores but not between any other instruments. These findings suggest that health-related quality of life should be examined during the rehabilitation process of individuals with CAI.

RESUMO Objetivo: descrever os índices de medos, crenças e evitação em policiais militares portadores de dor lombar crônica, acompanhados pelo Grupo de Coluna Vertebral do Hospital da Polícia Militar de Minas Gerais (PMMG). Materiais e métodos: durante um período de três anos, estas variáveis foram medidas pelo Fear-avoidance beliefs questionnaire (FABQ) versão português-brasileira, preenchido por autorrelato. As demais variáveis utilizadas para classificação da amostra em subgrupos e comparação destes quanto aos seus escores no FABQ foram idade, sexo, histórico de procedimento invasivo de coluna, presença de radiculopatia e encaminhamento pela Junta Central de Saúde (JCS), órgão oficial de perícias médicas na PMMG. Resultados: 248 militares preencheram o questionário satisfatoriamente e foram incluídos no estudo. A média de pontuação do FABQ-Work foi de 23,18 ± 10,79, enquanto a média de pontuação do FABQ-Phys foi de 18,10 ± 6,09. Não foram encontradas diferenças significativas nos escores dos subgrupos divididos por sexo, histórico de procedimento invasivo ou presença de radiculopatia. Indivíduos com idade superior a 40 anos apresentaram maiores índices de medo e evitação para atividades físicas (FABQ-Phys). Indivíduos que se encontravam em afastamento prolongado do trabalho (encaminhados pela JCS) apresentaram maior medo e evitação tanto para atividades físicas quanto atividades de trabalho. Conclusão: estes resultados permitiram identificar características dos policias militares em risco de incapacidade prolongada, ressaltando a necessidade de medidas educativas focadas na correção de crenças errôneas sobre dor lombar crônica para um melhor prognóstico na sua reabilitação.Palavras-chave: Dor lombar, Polícia, Medo, Questionários ABSTRACTObjectives: the purpose of this study was to describe fear-avoidance levels in military police agents with chronic low back pain followed by the Spine Group of the Military Police Hospital. Materials and Methods: The Brazilian Portuguese version of the Fear-avoidance Beliefs Questionnaire (FABQ) was applied during a three-year period. Secondary variables (age, sex, history of spinal invasive procedures, presence of radiculopathy, referral from medical experts due to prolonged sick-leave) were used for subgroup analysis and FABQ mean scores comparison. Results: 248 patients filled out FABQ correctly and were included in the study. FABQ-work and FABQ-Phys means were 23.18±10.79 and 18.10±6.09, respectively. There were no differences in FABQ scores between subgroups divided by sex, invasive procedures or radiculopathy. Age subgroup comparisons revealed that older individuals (> 40-years old) showed higher FABQ-Phys scores. Individuals with prolonged sick-leave showed higher scores at both FABQ-Phys and FABQ-Work subscales. Conclusion: Our results allowed identification of variables possibly related to long-time disability in military police agents and put emphasis on the need of educational interventions in which fear-avoidance beliefs are addressed in order to improve their rehabilitation prognosis.Keywords: Low back pain, Police, Fear, Questionnaires.
