RESUMO
BACKGROUND: The US National Institutes of Health (NIH) has produced a minimal data set to promote more accurate and consistent reporting of clinical trials, facilitating easier comparison of research on low back pain patients worldwide. The NIH-minimal dataset has not been previously translated into Turkish, and its features are currently unknown. This study aimed to adapt the NIH-Minimal Data Set into Turkish and investigate its validity and reliability in Turkish-speaking patients with chronic low back pain (CLBP). METHODS: In the study, 245 patients with CLBP were included. Test-retest and internal consistency analyzes were performed to evaluate the reliability of the NIH-minimal dataset. The intraclass correlation coefficient (ICC2,1) value was used to assess test-retest analysis. Cronbach's alpha value was calculated for internal consistency. Total impact scores of the NIH-minimal dataset were compared with total scores of the Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) to assess construct validity. The minimal detectable change (MDC95) was calculated based on the standard error of measurement (SEM95). RESULTS: The NIH-Minimal Data Set was found to have high test-retest reliability (ICC2,1 = 0.928) and high internal consistency (Cronbach α = 0.905). The NIH-minimal dataset correlated well with RMDQ and ODI (r = 0.750 and 0.810, respectively). There were no floor or ceiling effects. Also, SEM95 and MDC95 for the total score were 4.57 and 12.55, respectively. CONCLUSION: Considering all these data, it was concluded that the Turkish version of the NIH-minimal dataset is a valid and reliable outcome measure for evaluating patients with CLBP.
RESUMO
BACKGROUND: Patellofemoral pain and patellofemoral osteoarthritis are highly prevalent knee disorders associated with pain and functional limitations. The subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) was developed to evaluate patients with patellofemoral pain and osteoarthritis. PURPOSE: This study aims to translate the KOOS-PF into Turkish and assess its measurement properties. METHODS: The Turkish version of the KOOS-PF was tested for reliability and validity in a convenience sample of 55 patients with patellofemoral pain and/or osteoarthritis. Reliability analyses were conducted through a retest 7-14 days later with a subgroup of 35 patients. The KOOS-PF was compared with Kujala's Anterior Pain Scale (AKPS) and the Short Form-36 health survey (SF-36) to assess construct validity. Additionally, responsiveness analyses were performed on 29 patients who were followed up with a home-based exercise program three months later. RESULTS: The Turkish version of KOOS-PF has high test-retest reliability (ICC2,1 = 0.96) and internal consistency (Cronbach's α = 0.91). It has a very good correlation with the AKPS (r = 0.77) and the SF-36 physical component summary (r = 0.64) with no floor or ceiling effects. Responsiveness is confirmed by a good correlation with the global rating of change score (r = 0.51). The minimal clinically important change is 16.5 points, and the minimal important difference is 10.2. CONCLUSION: The Turkish version of the KOOS-PF is valid, reliable, and responsive for evaluating patients with patellofemoral pain and/or osteoarthritis.
RESUMO
PURPOSE: To evaluate the clinical results of arthroscopic repair and open Ahlgren-Larsson method in patients with chronic lateral ankle instability. METHODS: We retrospectively evaluated 60 patients who were operated in our clinic between 2010 and 2018 with the diagnosis of chronic lateral ankle instability. Preoperative and postoperative clinical evaluations were performed with AOFAS ankle-hindfoot score, FAOS, and VAS scores. RESULTS: Sixty patients with chronic lateral ankle instability were evaluated. 28 patients were treated with Ahlgren-Larsson method, and 32 patients were treated with arthroscopic repair. Follow-up duration was 35 ± 12 months for the open surgery group and 19 ± 2 months for the arthroscopic surgery group. The mean age of the arthroscopy group was 44 ± 9; the mean age of the open surgery group was 46 ± 11. There was no significant difference between the groups in terms of demographic features (age, sex, BMI). Postoperative clinical improvement was observed in both groups. There was no statistically significant difference between the groups in terms of functionality. However, there was a statistically significant difference in VAS in terms of pain and patient satisfaction in favor of arthroscopy group. CONCLUSIONS: Ahlgren-Larsson method and arthroscopic repair technique are safe and effective for chronic lateral ankle instability. Arthroscopic technique may be preferred for pain and patient satisfaction as it is less invasive and less morbid. LEVEL OF EVIDENCE: II.

OBJECTIVE: The aim of this study was to translate and cross-culturally adapt the Nonarthritic Hip Score (NAHS) into Turkish and determine the validity and reliability of the translated version in physically active patients with hip pain. METHODS: Sixty young to middle-aged and physically active patients (34 women and 26 men; mean age=35 years; age range: 18-40 years) with hip pain were included in the study. The original version of the NAHS was first translated into Turkish and back-translated into English by two bilingual translators each. The back-translated version was compared with the initial English version by a committee of the four translators. The Turkish version was then tested with 15 patients with hip pain and 15 healthy individuals. The participants were asked whether they had difficulties in understanding the questions. Subsequently, the questionnaire was accepted for use in the study population. Test-retest reliability and internal consistency were assessed using Intraclass Correlation Coefficient (ICC) and Cronbach's alpha, respectively. The construct validity was determined via the Pearson correlation coefficient between the NAHS and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), modified Harris Hip Score (mHHS), and Short Form-12 (SF-12). Floor and ceiling effects were analyzed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to test construct validity. RESULTS: An ICC of 0.994 and Cronbach's alpha value of 0.908 were obtained; thus, the Turkish version of the NAHS was reliable. Neither floor nor ceiling effects (15%) were found in the sub-parameters (8.3-1.7%) and the total score (1.7%) of the NAHS. The EFA test showed that this questionnaire had four factors. Model fit indices in CFA were χ2/df=2.23, Tucker-Lewis index=0.90, comparative fit index=0.91, goodness of fit index=0.63, root mean square error of approximation=0.14 (90% CI: 0.12-0.16). The NAHS total score showed an excellent correlation with WOMAC (r=-0.909), mHHS (r=0.850), and SF-12 (r=0.811) scores. CONCLUSION: The Turkish version of the NAHS is a valid and reliable questionnaire for young and physically active patients with hip pain. LEVEL OF EVIDENCE: Level II, Diagnostic study.
