“…These authors did not find any significant problems and/or difficulties in the cross-cultural adaptation process. The lack of difficulties in comprehension for the participants during the cross-cultural process is consistent with other studies [ 17 , 28 , 29 ]. Moreover, our new Spanish language version achieved good readability.…”

BackgroundThe Shoulder Pain and Disability Index (SPADI) is a tool designed to evaluate the impact of shoulder pathology. The aim of this study was to cross culturally adapt a Spanish version of the SPADI for Spanish population with a musculoskeletal shoulder pain, and to determine the psychometric properties of this instrument using confirmatory factor analysis (CFA).MethodsCross-cultural adaptation was performed according to the international guidelines. To assess factor structure, a confirmatory factor analysis was done. Internal consistency was measured using Cronbach’s alpha. Item-total and inter-item correlations were assessed. Pearson and Spearman correlations were calculated to assess the convergent validity between SPADI and quick-DASH.ResultsA new Spanish version of SPADI was achieved. The original SPADI factor structure was tested by CFA, obtaining a poor fit: relative chi-square (χ2/df) 3.16, CFI 0.89, NFI 0.92, and RMSEA 0.10 (90 % CI 0.08 to 0.12). An additional model was tested, after deleting items which have had a poor adjustment in the model (1, 11, and 12), obtaining the best fit: relative chi-square (χ2/df) of 1.94, CFI 0.98, NFI 0.95, GFI 0,95, and RMSEA 0.06 (90 % CI 0.04 to 0.09). The analysis confirmed the bidimensional structure (pain and disability subscales). A correlation Spearman’s Rho coefficient of 0.752 (p < 0.0001) and a Cronbach’s alpha of 0.90 were obtained.ConclusionsThis study validated a new 10-items version of SPADI for Spanish population with musculoskeletal shoulder pain providing a patient reported outcome measure that could be used in both clinical practice and research.

“…Similar to other cross-cultural studies on SPADI [ 30 – 32 ], we found a strong correlation between the SPADI and the Quick-DASH indicating good convergent validity. Alsanawi et al [ 33 ] found a correlation between the SPADI and DASH of 0.84 (Spearman coefficient), while Ebrahimzadeh et al [ 28 ] reported a correlation of 0.61.…”

“…Similar to those of prior validation studies, Persian version of modified ODQ was found to be valid and reliable for low back pain disability assessment in an Iranian population. For a patient centered tool, slight differences tailored for cultural adaptation are acceptable as far as the results prove to be valid and reliable [ 12 ].…”

Study DesignProspective study.PurposeWe aimed to validate the Persian version of the modified Oswestry disability questionnaire (MODQ) in patients with low back pain.Overview of LiteratureModified Oswestry low back pain disability questionnaire is a well-known condition-specific outcome measure that helps quantify disability in patients with lumbar syndromes.MethodsTo test the validity in a pilot study, the Persian MODQ was administered to 25 individuals with low back pain. We then enrolled 200 consecutive patients with low back pain to fill the Persian MODQ as well as the short form 36 (SF-36) questionnaire. Convergent validity of the MODQ was tested using the Spearman's correlation coefficient between the MODQ and SF-36 subscales. Intraclass correlation coefficient (ICC) and Cronbach's α coefficient were measured to test the reliability between test and retest and internal consistency of all items, respectively.ResultsICC for individual items ranged from 0.43 to 0.80 showing good reliability and reproducibility of each individual item. Cronbach's α coefficient was 0.69 showing good internal consistency across all 10 items of the Persian MODQ. Total MODQ score showed moderate to strong correlation with the eight subscales and the two domains of the SF-36. The highest correlation was between the MODQ and the physical functioning subscale of the SF-36 (r=–0.54, p<0.001) and the physical component domain of the SF-36 (r=–0.55, p<0.001) showing that MODQ is measuring what it is supposed to measure in terms of disability and physical function.ConclusionsPersian version of the MODQ is a valid and reliable tool for the assessment of the disability following low back pain.

“…To answer the questions, subjects place a mark on a numbered scale ranging from "0 (for no pain and difficulty) to 10 (for maximum pain, or difficulty in function, so that the patient needs help)" for each question [30]. Validity and reliability of this questionnaire in Persian version has been confirmed in previous researches [31].…”

Electrical interferential current stimulation versus electrical acupuncture in management of hemiplegic shoulder pain and disability following ischemic stroke-a randomized clinical trial

et al. 2020

Background: Hemiplegic Shoulder Pain (HSP) is among common complications occurring after stroke leading to disability. This study was conducted to compare the effects of electrical Interferential Current stimulation (IFC) and Electrical Acupuncture (EAC) on pain intensity, range of motion, and functional ability in patients with HSP and also comparing the two modalities regarding improvement of above indices. Methods: In this randomized clinical trial, 46 patients with HSP caused by ischemic stroke were recruited and assigned into 2 groups. Conventional exercise trainings were applied for both groups. Group A received additional IFC with medium frequency of 4000 HZ, and Group B received additional EAC two times a week for a total of 10 sessions. Pain severity, daily function, and shoulder Range of Motion (ROM) were evaluated using Visual Analogue Scale (VAS), Shoulder Pain and Disability Index (SPADI), and goniometry, respectively before and 5 weeks after the treatment. Results: Both groups showed relative improvement in pain severity, SPADI score, and its subscales, and also active and passive shoulder ROM after the treatment. However, IFC group compared to EAC group had higher mean changes of active ROM in abduction (28.00 ± 3.81 vs. 12.25 ± 2.39) and functional subscale of SPADI (11.45 ± 1.88 vs. 5.80 ± 1.66) after the treatment. On the contrary, EAC group showed higher percentage of VAS changes (46.14 ± 6.88 vs. 34.28 ± 5.52), indicating better pain improvement compared to IFC group. Other parameters did not show significant difference between two groups. Conclusion: Both IFC and EAC caused short term improvement in functional state, increased motion, and decreased pain in patients with HSP. Although pain control was more evident in acupuncture group, IFC resulted in better effects on function and active ROM of abduction, and seems to have higher efficacy. Trial registration: This clinical trial was registered in the Iranian Registry of Clinical Trials at 2016-07-16 with a registry number of IRCT201602153217N10.
