RESUMO
OBJECTIVE: Large numbers of people are subject to alterations and pathologies in the foot. To quantify how these problems of foot function affect the quality of life, clinicians and researchers have developed measures such as the Foot Function Index (FFI). Our aim is to determine the methodological quality of the FFI including adaptations to other languages. DATA SOURCES: The studies considered in this review were extracted from the PubMed, Embase and CINAHL databases. The inclusion criteria were followed: (1) studies of patients with no previous foot or ankle pathology and aged over 18 years; (2) based on English-language patient-reported outcome measures that assess foot function; (3) the patient-reported outcome measures should present measurement properties based on COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria. REVIEW METHODS: The systematic review was conducted following the COSMIN criteria to establish the methodological quality of the original FFI, together with its variants and adaptations. The last search was carried out in May 2024. RESULTS: Of the 1994 studies obtained in the preliminary search, 20 were eligible for inclusion in the final analysis. These results are the validations and cross-cultural adaptations to the following languages: the original FFI has cross-cultural adaptation in 13 languages and the FFI-Revised Short Form has been adapted and validated for use in 2 languages. CONCLUSION: In terms of methodological quality, the FFI-Revised Short Form questionnaire is a valuable instrument for evaluating ankle and foot function and could usefully be expanded to be available in more languages.
RESUMO
OBJECTIVES: To cross-culturally adapt and validate a Spanish version of the Exercise-Induced Leg Pain questionnaire. DESIGN: Clinical measurement study. PARTICIPANTS: The validity and reliability of the adapted version were assessed in four groups of 40 patients with exercise-induced leg pain, 40 physically active healthy individuals (control group), 40 athletes with other leg conditions and 40 athletes, military personnel and candidates with no history of injury (risk group). MAIN MEASURE: Exercise-Induced Leg Pain questionnaire. REFERENCE MEASURES: Spanish version of the Short-Form 36 and Schepsis postsurgical classification scale. RESULTS: In patients with exercise-induced leg pain, the mean age was 24.9 (± 6.7) years and the mean score of the questionnaire was 62.8 (± 10.9). The standard error of measurement and minimum detectable change threshold were 1.67 and 4.63 points, respectively. Excellent internal consistency (Cronbach's α = 0.942) and test-retest reliability (intraclass correlation coefficient = 0.995) were found. The exploratory and confirmatory factor analyses indicated that a one-factor solution explained 66.84% of the variance. For construct validity, 87.5% of the previously stated hypotheses were fulfilled between the total score of the questionnaire and Short-Form 36 dimensions. Concurrent validity, assessed by the Schepsis scale, was almost perfect (r = 0.92, p < 0.001). The predictive validity of the questionnaire was demonstrated using the receiving operating curve (area of 0.992; 95% CI: 0.983-1, p < 0.001). CONCLUSION: The Spanish version of the Exercise-Induced Leg Pain questionnaire resulted in a reliable and valid instrument to assess patients with exercise-induced leg pain.

Background and Objectives: To determine the most commonly used patient-reported outcome measures (PROMs) in exercise-induced leg pain (EILP) and to identify specific PROMs for EILP in order to evaluate their psychometric properties and methodological quality. Materials and Methods: A strategic search was performed in different databases to identify and extract the characteristics of studies based on the use of PROMs in patients with EILP. Specific PROMs were evaluated according to the Terwee et al. and COSMIN criteria. Results: Fifty-six studies were included in the review. The Medial Tibial Stress Syndrome Score (MTSSS), Lower Extremity Functional Scale (LEFS) and Exercise-Induced Leg Pain Questionnaire (EILP-Q) were identified as specific PROMs for EILP. The Visual Analog Scale (VAS) was the most widely used instrument in the assessment of EILP. The methodological quality assessment showed six positive values for the LEFS, four for the MTSSS and three for the EILP-Q for the eight psychometric properties analyzed according to the COSMIN criteria. The evaluation of the nine psychometric properties according to Terwee showed five positive values for the LEFS and MTSSS, and three for the EILP-Q. Conclusions: The overall methodological quality of the PROMs used was low. The VAS was the most widely used instrument in the assessment of EILP, and the LEFS was the highest quality PROM available for EILP, followed by the MTSSS and EILP-Q, respectively.

BACKGROUND Tarsometatarsal joint (TMJ) arthrodesis is common method used for correcting hallux abductus valgus (HAV). Its popularity has grown due to studies revealing HAV's triplanar deformity with frontal plane rotation. This case report presents a 28-year-old woman with Down syndrome, congenital heart disease, and a history of knee surgery and plantar fasciitis, with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. CASE REPORT Examination revealed severe foot deformities, and radiographic studies confirmed the condition. A surgical intervention was planned, and the patient's cardiologist confirmed she was fit for the procedure. The modified Lapidus technique with frontal plane rotational correction included realigning the metatarsal joint, resecting spurs, osteosynthesis material, and arthrosis in the sinus tarsi. After surgery, the patient underwent a recovery period without support for 8 weeks and received appropriate medical care. Radiographs showed successful alignment, and the patient gradually resumed her daily activities. The patient had an uneventful recovery, and postoperative radiographs showed good alignment in all planes. CONCLUSIONS The hyperlaxity associated with Down syndrome makes the incidence of HAV more frequent, and TMJ fusion is preferable to correction by osteotomy. The modified Lapidus technique with frontal plane rotational correction could be a good technique to achieve satisfactory correction in patients with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. TMJ fusion is indicated when severe or recurrent rotational component is observed in X-rays.

BACKGROUND: the main aim of this study was to analyze the relationship between sole pattern parameters of football boots with the frequency of injuries that occur in semiprofessional and amateur footballers. METHODS: The study sample was composed of 77 male football players. All were at least 18 years old, played at least 10 h per week, gave signed informed consent to take part and properly completed the Visual Analogue Scale. This study analysed data from each player's medical history, including age, injuries, years of practice, field type and surface condition information. RESULTS: The visual analogic score in semiprofessional players was higher (2.05 ± 2.43) than in amateur players (1.00 ± 1.1). A total of 141 lesions were collected, equivalent to 1.81 injuries for each football player studied (n = 77). The result of the ROC curve indicated that the player's years of practice could predict significantly (p < 0.05) the presence of lower limb injuries, with an area under the curve of 0.714. CONCLUSIONS: This study described the predictive capacity of sole pattern characteristics concerning lower limb injuries in amateur and semiprofessional footballers. Football boot variables associated with the number of studs were associated with foot and ankle overload injuries.

The purpose of this cross-sectional study was to analyse the relationship of neuromuscular performance and spatiotemporal parameters in 18 adolescent distance athletes (age, 15.5 ± 1.1 years). Using the OptoGait system, the power, rhythm, reactive strength index, jump flying time, and jump height of the squat jump, countermovement jump, and eight maximal hoppings test (HT8max) and the contact time (CT), flying time (FT), step frequency, stride angle, and step length of running at different speeds were measured. Maturity offset was determined based on anthropometric variables. Analysis of variance (ANOVA) of repeated measurements showed a reduction in CT (p < 0.000) and an increase in step frequency, step length, and stride angle (p < 0.001), as the velocity increased. The HT8max test showed significant correlations with very large effect sizes between neuromuscular performance variables (reactive strength index, power, jump flying time, jump height, and rhythm) and both step frequency and step length. Multiple linear regression found this relationship after adjusting spatiotemporal parameters with neuromuscular performance variables. Some variables of neuromuscular performance, mainly in reactive tests, were the predictors of spatiotemporal parameters (CT, FT, stride angle, and VO). Rhythm and jump flying time in the HT8max test and power in the countermovement jump test are parameters that can predict variables associated with running biomechanics, such as VO, CT, FT, and stride angle.

Anaerobic power and capacity are considered determinants of performance and are usually assessed in athletes as a part of their physical capacities' evaluation along the season. For that purpose, many field tests have been created. The main objective of this study was to analyze the agreement between four field tests and a laboratory test. Nineteen CrossFit® (CF) athletes were recruited for this study (28.63 ± 6.62 years) who had been practicing CF for at least one year. Tests performed were: (1) Anaerobic Squat Test at 60% of bodyweight (AST60); (2) Anaerobic Squat Test at 70% of bodyweight (AST70); (3) Repeated Jump Test (RJT); (4) Assault Bike Test (ABT); and (5) Wingate Anaerobic Test on a cycle ergometer (WG). All tests consisted of 30 s of max effort. The differences among methods were tested using a repeated-measures analysis of variance (ANOVA) and effect size. Agreement between methods was performed using Bland-Altman analysis. Analysis of agreement showed systematic bias in all field test PP values, which varied between -110.05 (AST60PP-WGPP) and 463.58 (ABTPP-WGPP), and a significant proportional error in ABTPP by rank correlation (p < 0.001). Repeated-measures ANOVA showed significant differences among PP values (F(1.76,31.59) = 130.61, p =< 0.001). In conclusion, since to our knowledge, this is the first study to analyze the agreement between various methods to estimate anaerobic power in CF athletes. Apart from ABT, all tests showed good agreement and can be used interchangeably in CF athletes. Our results suggest that AST and RJT are good alternatives for measuring the anaerobic power in CF athletes when access to a laboratory is not possible.
