Abstract
BACKGROUND Translation and validation of important scales in other languages reduce bias in reporting the functional status of the patient. OBJECTIVE To translate the Back Pain Functional Scale into Urdu (BPFSu), adapt it for use in other cultures, and evaluate its psychometric properties. METHOD According to Beaton guidelines, translation and cultural adaption was carried out. On 100 Urdu-literate men and women aged 18-60 years with lower back pain, the final BPFSu was assessed for psychometric qualities. First at baseline and again after 7 days, participants completed the BPFSu, the Functional Rating Index (FRI), and the Numeric Pain Rating Scale (NPRS). RESULTS Internal consistency of the BPFSu was excellent (Cronbach's alpha: 0.937). No floor and ceiling effects were found Excellent test-retest reliability (ICC = 0.882, CI 95%; 0.830-0.919) was achieved. Spearman correlation coefficient showed criterion validity with the NPRS (rho =â0.701, p⩽ 0.001) and Pearson correlation coefficient showed construct validity with the FRI (r=â0.740, p⩽ 0.001). The minimum detectable changes were 9.96, while the standard error of measurement was 3.6. CONCLUSION The BPFSu is a valid and reliable instrument for assessing physical function in individuals experiencing low back discomfort.

Abstract
PURPOSE This study cross-culturally adapted and psychometrically validated a simplified Chinese version of the Exercise-Induced Leg Pain Questionnaire (SC-EILP) for evaluating the severity of symptoms and sports ability among individuals with exercise-induced leg pain. MATERIALS AND METHODS One hundred and fourteen participants with exercise-induced leg pain were included. To assess reliability, we calculated Cronbach's α and intra-class correlation coefficient (ICC). Construct validity was analysed by assessing the correlations between SC-EILP and visual analogue scale (VAS), University of California Los Angeles activity score (UCLA), and short form (36) health survey (SF-36). Factorial validity was used to establish the factor structure of the questionnaire. RESULTS The EILP was cross-culturally well-adapted and translated into simplified Chinese. Each item was appropriately correlated with the total items. SC-EILP had nearly good reliability [Cronbach's α = 0.798, ICC = 0.897, 95% confidence interval 0.851-0.929]. The elimination of any one item in all did not result in a value of Cronbach's α of <0.80. SC-EILP had a very good correlation with VAS (-0.607, p < 0.01) and a moderate correlation with UCLA (0.581, p < 0.01) and physical domains of SF-36 (0.499-0.528, p < 0.01). Exploratory factor analysis revealed the 3-factor loading explained 74.736% of the total variance [Kaiser-Mayer-Olkin (KMO) = 0.672, C2 = 665.34, p < 0.001]. CONCLUSIONS SC-EILP showed excellent acceptability, internal consistency, reliability, and construct validity, and could be recommended for individuals in Mainland China.

[PMID: 36494873 PMCID: PMC9733288 DOI: 10.1186/s40001-022-00936-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 12/05/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Under the obvious acetabular superolateral bone defect of Crowe II/III hips, this study aimed to investigate the difference in surgical technique of different hip center positions from the surgical data and clinical outcomes. METHODS From July 2007 to December 2016, 87 patients (106 Crowe II/III hips) consecutively received total hip arthroplasty (THA). The minimum follow-up time was 5 years. The mean limb length discrepancy was 1.97 ± 1.81 cm. Twenty-four hips had surgical histories. The patients were divided into three groups according to the acetabular prosthesis positions, depending on the Crowe classification, respectively, group 1 (Crowe I), group 2 (Crowe II) and group 3 (Crowe III). The surgical data and clinical results were used to evaluate the outcome of different surgical techniques of different hip center positions, including surgical time, blood loss, blood transfusion, number of osteotomy hips, osteotomy length, the distribution of prothesis, postoperative inpatient days, Harris hip scores, Visual Analogue Scale (VAS), Back Pain Function Scale (BPFS) and complications. RESULTS The mean follow-up time was 8.93 ± 2.55 years. Nineteen hips performed intraoperative osteotomy. From group 1 to group 3, the mean osteotomy length were 0.53 ± 1.11 cm, 0.05 ± 0.22 cm, and 0.00 ± 0.00 cm, respectively (p = 0.083); the surgical time were 142.57 ± 57.94 min, 118.4 ± 41.22 min, and 120.00 ± 84.85 min, respectively (p = 0.324); the blood loss were 498.21 ± 368.53 mL, 333.33 ± 167.62 mL, and 350.00 ± 212.13 mL, respectively (p = 0.255); the blood transfusion were 288.48 ± 381.68 mL, 128.00 ± 235.17 mL, and 385.00 ± 219.20 mL, respectively (p = 0.199); the postoperative inpatient days were 7.95 ± 4.42 d, 7.47 ± 4.29 d, and 6.50 ± 0.71 d, respectively (p = 0.831). Among the groups, the distribution of acetabular prosthesis, acetabular liner, acetabular prosthesis sizes, femoral head sizes and femoral prothesis distal sizes were not significantly different (p > 0.05). Only the distribution of femoral prosthesis was significantly different (p = 0.046); the Harris, VAS, BPFS, and the distribution of complications were not significantly different (p > 0.05). CONCLUSIONS We provided a framework to guide decision-making in Crowe II/III hips for surgeons: the surgical technique of different hip center positions was stable and had good outcomes, but the acetabular prothesis position and femoral prothesis should be determined according to the intraoperative situation. LEVEL OF EVIDENCE Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.
