Cross-cultural adaptation and validation of the Chinese version of the shoulder pain and disability index in patients with symptomatic shoulder pain: A prospective case series

The Greek version of shoulder rating questionnaire (SRQ): Translation, cultural adaptation, a reliability and validity study in patients with rotator cuff related shoulder pain

BACKGROUND

The Shoulder Rating Questionnaire (SRQ) was created in the English language to assess shoulder disorders in six areas: global function, pain, daily activities, recreational and athletic activities, and work.

PURPOSE

The study aimed to translate and culturally adapt Shoulder Rating Questionnaire (SRQ) into Greek.

METHODS

The SRQ English version was translated and adapted into the Greek language using forward translation, expert panel synthesis, and backward translation procedures. A pilot testing has been made in the target population, and the final version was created. A cross-sectional study was conducted in clinical settings with the SRQ and the Shoulder Pain and Disability Index. A total of 168 Greek adult patients with rotator cuff-related shoulder pain were recruited from physical therapy clinics. Τhe reliability of the SRQ Greek version was assessed using intraclass correlation coefficients. Internal consistency was assessed using the Cronbach alpha coefficient. Concurrent validity was measured by correlating the Shoulder Rating Questionnaire with the Shoulder Pain and Disability Index using Pearson's correlation coefficient.

RESULTS

The results showed that the SRQ Greek version has excellent internal consistency (Cronbach's α = 0.99), test-retest reliability (ICC = 0.976), and concurrent validity (r > 0.9). No ground or ceiling effects were found. The standard error of measurement and the minimum detectable change of the total score were 5.55 and 15.38.

CONCLUSIONS

The Greek Language Version of the SRQ is a reliable and valid instrument that can be used to evaluate adult patients with shoulder rotator cuff-related disorders in the acute or chronic phases and in clinical trials.

Psychometric analysis of the questionnaires for the assessment of upper limbs available in their Italian version: a systematic review of the structural and psychometric characteristics

INTRODUCTION

There is no systematic review that analyzes the psychometric properties of questionnaires in Italian. Previous studies have analyzed the psychometric characteristics of instruments for the measurement of pathologies of upper limbs and their joints in different languages. The aim of the present study was to analyze the psychometric properties of the questionnaires published in Italian for the evaluation of the entire upper limb or some of its specific regions and related dysfunctions.

EVIDENCE ACQUISITION

For the development of this systematic review, the following databases were used: PubMed, Scopus, Cochrane, Dialnet, Cinahl, Embase and PEDro. The selection criteria used in this study were: studies of transcultural adaptation to Italian of questionnaires oriented to the evaluation of upper limbs or any of their structures (specifically shoulder, elbow and wrist/hand), and contribution of psychometric variables of the questionnaire in its Italian version.

EVIDENCE SYNTHESIS

After reading the titles and applying the inclusion and exclusion criteria to the complete documents, 16 documents were selected: 3 for the upper limb, 8 for the shoulder, 1 for the elbow and 4 for the wrist and hand. The cross-sectional psychometric variables show levels between good and excellent in all the questionnaires. Longitudinal psychometric variables had not been calculated in the vast majority of the analyzed questionnaires.

CONCLUSIONS

Italian versions of the questionnaires show good basic structural and psychometric characteristics for the evaluation of patients with musculoskeletal disorders of the upper limb and its joints (shoulder, elbow and wrist/hand).

Development and Validation of a Simplified Chinese Version and a Face-Scale Version of the Oxford Shoulder Score: A 2-Center Prospective Study

Background

There has not yet been a pictorial version of a patient-reported outcome measure for shoulder pain.

Purpose

To translate the English version of the Oxford Shoulder Score (OSS) to a simplified Chinese version (SC-OSS) and to validate a new face-scale version of the OSS (FS-OSS), while investigating cross-cultural adaptation, validation, and reproducibility of both versions in patients with shoulder pain.

Study Design

Cohort study (diagnosis); Level of evidence, 2.

Methods

The translation and cross-cultural adaptation of the SC-OSS was performed using a forward-backward translation method. The FS-OSS was developed on the basis of the SC-OSS, using the Wong-Baker FACES Pain Rating Scale for reference. Participants were asked to complete the SC-OSS, FS-OSS, Simple Shoulder Test (SST), Constant-Murley score (CMS), and 36-Item Short Form Health Survey (SF-36). Validation and reproducibility were tested by calculating Cronbach α values for internal consistency as well as by intraclass correlation coefficients. Time needed to complete the scores was used to test cross-cultural adaption.

Results

A total of 312 respondents participated in the research and completed all outcome measures. The internal consistency was strong, with a Cronbach α of .94 and .91 for the FS-OSS and SC-OSS, respectively. High intraclass correlation coefficient values for the FS-OSS score (0.95) and SC-OSS (0.92) were obtained, which indicated excellent test-retest reliability. The Pearson correlation coefficients of the SC-OSS and FS-OSS with the SST (r = 0.67 and 0.65, respectively), CMS (r = 0.62 and 0.66, respectively), and SF-36 (r = 0.52 and 0.57, respectively) indicated good construct validity. The time needed to complete the FS-OSS was less than that needed for the SC-OSS and SST.

Conclusion

The FS-OSS and SC-OSS were validated as reliable instruments for patients with shoulder pain. For Chinese patients, the face-scale version was easier to understand than the cross-cultural text version.

Validation and reliability of a Japanese version of the Shoulder Pain and Disability Index: A cross-sectional study

BACKGROUND

The Shoulder Pain and Disability Index (SPADI) is a simple disease specific questionnaire that is used to evaluate the impact of shoulder disorders. The purpose of this study was to translate the SPADI into Japanese (SPADI-Jp) and evaluate its reliability and validity in Japanese patients with shoulder disorders.

METHODS

Cross-cultural adaptation of the SPADI was performed according to international guidelines. A total of 100 patients with shoulder disorders participated in this study. Each participant was asked to finish the SPADI-Jp, Disability of Arm, Shoulder and Hand (DASH), and the Short-Form 36 (SF-36) at the initial visit. Thirty-four patients repeated the SPADI-Jp to assess the test-retest reliability. The test-retest reliability was quantified using the interclass correlation coefficient (ICC), while Cronbach's alpha was calculated to assess the internal consistency. The construct validity was assessed using Spearman's rank correlation coefficients.

RESULTS

Internal consistency in the SPADI-Jp was very high (0.969), as measured by the Cronbach's alpha. The ICC of the SPADI-Jp was 0.930. There was a strong, positive correlation between the DASH and the SPADI-Jp (r = 0.837, p < 0.001). The SPADI-Jp was significantly correlated with most of the SF-36 subscales. The correlations of the SPADI-Jp with physical subscales of the SF-36 were stronger than those with the other subscales.

CONCLUSIONS

We demonstrated that the SPADI-Jp is a reliable and valid self-assessment tool. Because cross-cultural adaptation, validation, and reliability of the disease-specific questionnaire for shoulder pain and disability have not been evaluated in Japan, the SPADI-Jp can be useful for evaluating such patients in the Japanese population.

How to Assess Shoulder Functionality: A Systematic Review of Existing Validated Outcome Measures

The objective of this review was to compile validated functional shoulder assessment tools and analyse the methodological quality of their validations. Secondarily, we aimed to provide a comparison of the tools, including parameter descriptions, indications/applications, languages and operating instructions, to choose the most suitable for future clinical and research approaches. A systematic review (PRISMA) was conducted using: PubMed, WoS Scopus, CINHAL, Dialnet and reference lists until 2020. The main criteria for inclusion were that papers were original studies of validated tools or validation studies. Pre-established tables showed tools, validations, items/components, etc. The QUADAS-2 and COSMIN-RB were used to assess the methodological quality of validations. Ultimately, 85 studies were selected, 32 tools and 111 validations. Risk of bias scored lower than applicability, and patient selection got the best scores (QUADAS-2). Internal consistency had the highest quality and PROMs development the lowest (COSMIN-RB). Responsiveness was the most analysed metric property. Modified UCLA and SST obtained the highest quality in shoulder instability surgery, and SPADI in pain. The most approached topic was activities of daily living (81%). We compiled 32 validated functional shoulder assessment tools, and conducted an analysis of the methodological quality of 111 validations associated with them. Modified UCLA and SST showed the highest methodological quality in instability surgery and SPADI in pain.

Measurement properties of translated versions of the Shoulder Pain and Disability Index: A systematic review

PURPOSE

To summarise measurement properties of translated versions of the Shoulder Pain and Disability Index (SPADI) and to assess their methodological quality.

METHODS

Relevant studies testing measurement properties of translated versions of the SPADI in non-specific shoulder pain participants were included from 11 databases (August 2020). Two reviewers independently screened articles and assessed individual measurement property risk of bias using the COSMIN checklist as very good, adequate, doubtful or inadequate. For each measurement property results were pooled and rated sufficient, insufficient, or inconsistent. Synthesised evidence was graded as high, moderate, low or very low (GRADE approach).

RESULTS

Thirty-four studies (21 languages and 26 different versions) were included from 4402 articles. A total of 141 measurement properties were reported with 60 rated as very good or adequate. These included; internal consistency (19), test-retest reliability (4), construct validity (6), structural validity (10), measurement error (5), responsiveness (9), and cross-cultural validity (2). Comprehensibility was adequate in the Chinese, German, Nepali, Spanish and Urdu versions. Only the Danish, Dutch and Nepali versions confirmed all, or all but one, of their measurement properties with sound methodology. Pooled results of all measurement properties except structural validity were rated as sufficient. Quality of evidence was graded moderate to high with downgrading due to inconsistent results.

CONCLUSION

Overall evidence suggests the SPADI is valid, reliable and responsive in translated form but less than half the measurement properties tested were of adequate quality. Further testing is required in many languages particularly in; test-retest reliability, measurement error and construct validity.

Functional outcome of single stage capsular release and rotator cuff repair for cuff tear in periarthritic shoulder

Rotator cuff tear and periarthritic shoulder is a concomitant condition. In this study, both were managed with single stage arthroscopic Capsular release and rotator cuff repair and its functional outcome was evaluated till one year postoperatively. 58 patients diagnosed clinically, radiologically by MRI and arthroscopically were included. Mean constant shoulder score preoperatively was 32.6 and at one year postoperatively 78.5. Mean SPADI preoperatively was 72.1% which decreased to 20.7% at one year postoperatively. These improvements were statistically significant (p < 0.001). Thus this single stage procedure is effective for patients having rotator cuff tear in periarthritic shoulder.
