A questionnaire found disease-specific WORC index is not more responsive than SPADI and OSS in rotator cuff disease

The pursuit of ‘best practice’, health economic planning, the increasing awareness and expectations of patients, pressure from politicians and the media, and the emergence of league tables for surgeons are some of the reasons why orthopaedic surgeons are encouraged to adopt evidence-based

Study Design Clinical measurement. Background Recently, the Western Ontario Rotator Cuff Index (WORC) was shortened, but few studies have reported its measurement properties. Objective To compare the validity and responsiveness of the short version of the Western Ontario Rotator Cuff Index (Short-WORC) and the WORC (disease-specific measures) with those of the Shoulder Pain and Disability Index (SPADI) and the simple shoulder test (SST) (joint-specific measures); the Disabilities of the Arm, Shoulder and Hand (DASH) (a region-specific measure); and the Medical Outcomes Study 12-Item Short-Form Health Survey version 2 (SF-12v2) (a general health status measure) in patients undergoing rotator cuff repair (RCR). Methods A cohort of patients (n = 223) completed the WORC, SPADI, SST, DASH, and SF-12v2 preoperatively and at 3 and 6 months after RCR. Short-WORC scores were extracted from the WORC questionnaire. The construct validity (Pearson correlations) and internal responsiveness (effect size [ES], standardized response mean [SRM], relative efficiency [RE]) of the Short-WORC were calculated. Results The Short-WORC was strongly correlated with the WORC (r = 0.89-0.96) and moderately to strongly correlated with non-disease-specific measures at preoperative and postoperative assessments (r = 0.51-0.92). The Short-WORC and WORC were equally responsive (REShort-WORC/WORC = 1) at 0 to 6 months and highly responsive overall at 0 to 3 months (ESShort-WORC, 0.72; ESWORC, 0.92; SRMShort-WORC, 0.75; SRMWORC, 0.81) and 0 to 6 months (ESShort-WORC, 1.05; ESWORC, 1.12; SRMShort-WORC, 0.89; SRMWORC, 0.89). The responsiveness of the comparator measures (SPADI, SST, DASH, SF-12v2) was poor to moderate at 0 to 3 months (ES, 0.07-0.55; SRM, 0.09-0.49) and 0 to 6 months (ES, 0.05-0.78; SRM, 0.07-0.78). Conclusion The Short-WORC and WORC have similar responsiveness in patients undergoing RCR, and are more responsive than non-disease-specific measures. Future studies should focus on validation of the Short-WORC in samples representing the spectrum of rotator cuff disorders. J Orthop Sports Phys Ther 2018;48(5):409-418. doi:10.2519/jospt.2018.7928.

CORR Synthesis: What Is the Role of Platelet-rich Plasma Injection in the Treatment of Tendon Disorders?

BackgroundInstruments designed to measure the subjective impact of painful shoulder conditions have become essential in shoulder research. The Shoulder Pain and Disability Index (SPADI) is one of the most extensively used scales of this type. The objective of this study was to investigate reproducibility and responsiveness of the SPADI in patients with adhesive capsulitis.MethodsSPADI test-retest reproducibility was estimated by the "intraclass correlation coefficient" (ICC) and the "smallest detectable difference" (SDD). Responsiveness was assessed by exploring baseline and follow-up data recorded in a recently reported clinical trial regarding hydrodilatation and corticosteroid injections in 76 patients with adhesive capsulitis. "Standardized response mean" (SRM) and "reliable change proportion" (RCP) for SPADI were compared with corresponding figures for shoulder range-of-motion (ROM). The relationship between SPADI and ROM change scores was investigated through correlation and linear regression analyses.ResultsResults for test-retest reproducibility indicated a smallest detectable difference of 17 points on the 0–100 scale, and an intraclass correlation coefficient of 0.89. The SPADI was generally more responsive than ROM. Weak to moderately strong associations were identified between SPADI and ROM change scores. According to the regression model, the three variables baseline SPADI, baseline active ROM and change in active ROM together explained 60% of the variance in SPADI improvement.ConclusionThis study supports the use of SPADI as an outcome measure in similar settings.

Purpose To link the items from shoulder-specific Patient Reported Outcome Measures (PROMs) to the International Classification of Functioning, Disability and Health (ICF) domains and categories, and to determine if the items fit into the ICF framework. Materials and methods The Brazilian versions of the Oxford Shoulder Score (OSS), Shoulder Pain and Disability Index (SPADI), Simple Shoulder Test (SST) and Western Ontario Rotator Cuff Index (WORC) were linked to the ICF by two researchers independently. Agreement between raters was determined by calculating the Kappa Index. Results Fifty-eight items from the PROMs were linked to eight domains and 27 categories of ICF. The PROMs covered components of body functions, activities, and participation. Components of body structure and environmental factors were not covered by any of the PROMs. ​There was substantial agreement between raters when linking the OSS (Kappa index = 0.66), SPADI (Kappa index = 0.92), SST (Kappa index = 0.72) and WORC (Kappa index = 0.71). Conclusions WORC and SST were the PROMs that covered the highest number of ICF domains (seven and six, respectively). However, SST is short and may be less time consuming in a clinical assessment. Clinicians can benefit from this study to decide which shoulder-specific PROM may be more adequate according to the clinical demand. Implications For Rehabilitation Western Ontario Rotator Cuff Index was the shoulder-specific Patient Reported Outcome Measure (PROM) that best showed a broader view of functionality through the International Classification of Functioning, Disability and Health (ICF) domains that can influence shoulder pain and disability. Simple Shoulder Test seems to be the most recommended shoulder-specific PROM considering the number of domains covered by the ICF and the clinical evaluation time consumption. Shoulder Pain and Disability Index fails to provide a broader view of functioning through other ICF domains that may influence shoulder pain and disability.

The numeric pain rating scale (NPRS) and shoulder pain and disability index (SPADI) are commonly used patient-reported outcome measures (PROMs) in patients with rotator cuff tendinopathy. To date, there are gaps in the evidence supporting the clinimetric properties of these PROMs for patients treated with subacromial pain syndrome (SAPS). A clinimetric analysis (n=145) was performed to examine the reliability, construct validity, responsiveness, interpretability, minimal detectable change (MDC95) and minimum clinically important difference (MCID) of the NPRS and SPADI for "improved" (global rating of change from +3 to +7) and "much-improved" (global rating of change from +5 to +7) patients at 3-months follow-up. The NPRS (ICC: 0.86; 95 %CI, 0.33-0.96) and SPADI (ICC: 0.79; 95 %CI 0.12-0.94) exhibited good reliability and excellent responsiveness (NPRS: area under the curve (AUC)=0.96, 95 %CI 0.92-0.99; SPADI: AUC=0.90, 95 %CI 0.84-0.95) in this patient population. Both outcomes demonstrated strong construct validity (Pearson's r; p<0.001). The MDC95 was a 1.7- and 20.5-point change for the NPRS and SPADI, respectively. For the NPRS, the MCID was a 1.5-point change in the "improved" group and a 2.5-point change in the "much improved" group. For the SPADI, the MCID was an 18-point or 50% change for the "improved" group, and a 25-point or 70% change in the "much improved" group. The NPRS and SPADI demonstrated sound clinimetric properties in patients with SAPS. The MCID exceeded measurement error in the "much improved" group. Diagnosis, type of intervention, level of improvement, and measurement error should be considered when applying the MCID.

BackgroundThis study aimed to translate and culturally adapt a Greek version of the Shoulder Pain and Disability Index (SPADI) questionnaire and to validate its usage in Greek patients.Materials and methodsA forward and backward translation was performed, and the final version of the Greek questionnaire was administered to 134 outpatients (mean age 47.4 ± 14.5) with rotator cuff tear under conservative treatment. The questionnaire was re-administered 2–5 days later to assess test–retest reliability. Patients completed the Greek SPADI, the Greek version of the Quick DASH (Disability of the Arm, Shoulder and Hand Questionnaire) and the EuroQoL EQ-5D. 102 of the 134 questionnaires were considered valid.ResultsThe internal consistencies of the SPADI total and its subscales measured with Cronbach’s alpha coefficient were high (0.932 for SPADI-Total, 0.899 for SPADI-Disability, 0.905 for SPADI-Pain). Intraclass correlation coefficients showed excellent test–retest reliability (0.899 for Disability, 0.902 for Pain, and 0.929 for total SPADI). A significantly high positive correlation was found between the SPADI total score and its subscales, and Quick DASH for Pain and Disability. Significant correlations were also found between SPADI scales and EQ-5D variables. There was a moderate positive correlation with the variables “self-reliance” (r = 0.66), “common activities” (r = 0.58), and “pain/discomfort” (r = 0.49), and a weaker correlation with the “mobility” variable (r = 0.20). Factor analysis (PAF method) revealed a bidimensional formation of the SPADI. Eight items (five pain/three disability) weighted the first factor by >0.5, and five disability items weighted the second factor.ConclusionsThe Greek SPADI represents a valid and reliable tool for measuring pain and disability in patients with painful shoulder disorders.Level of evidenceLevel 3.

The purposes of this study were (1) to assess the construct validity of the Shoulder Pain and Disability Index (SPADI) and (2) to determine whether the SPADI is more responsive than the Sickness Impact Profile (SIP), a generic health status measure. The sample consisted of 94 patients who were diagnosed with a shoulder problem and referred to six outpatient physical therapy clinics. Clinically meaningful change was determined by use of an ordinal rating scale designed to determine whether the patient's shoulder function was improved, the same, or worse following treatment. Spearman rho correlations were calculated for the initial visit SPADI and SIP scores. The standardized response mean (SRM) was used to measure responsiveness for the patients who were judged to be improved. One-tailed paired t tests (alpha = .01) were used to determine whether differences existed among SRM values. Correlations between the SPADI and SIP scores ranged from r = .01 to r = .57. The SRM value was higher for the SPADI total score (SRM = 1.38) than for the SIP total score (SRM = 0.79). Most correlations between SPADI and SIP scores provided support for the construct validity of the SPADI. The SPADI does not appear to strongly reflect occupational and recreational disability and is more responsive than the SIP.

The aim of the present study was to investigate the effectiveness of prolotherapy injections in the treatment of failed rotator cuff repair surgery. Between May 2014 and March 2016, a total of 15 patients (5 males, 10 females; mean age 49.4±10.7 years; range, 33 to 71 years) with failed rotator cuff repair surgery who had at least six months of complaints and were refractory to at least of three months of conservative methods were included. Ultrasound-guided prolotherapy injections were performed under aseptic conditions, and the patients were instructed to carry out a home-based exercise program. Clinical assessment of shoulder function was performed using a visual analog scale (VAS) for pain, Shoulder Pain and Disability Index (SPADI), Western Ontario Rotator Cuff (WORC) Index, patient satisfaction and shoulder range of motion. All patients were examined at baseline, at Week 3, 6, and 12 and at the final follow-up visit. The intra-group comparison showed that the patients achieved significant improvements at all time points, compared to baseline as measured by VAS, SPADI, WORC index, and shoulder range of motion (p<0.001). Twelve patients (80%) reported excellent or good outcomes. Our study results show that prolotherapy is effective in the treatment of patients with failed rotator cuff repair surgery with significant improvements in the shoulder functions and pain relief.

BackgroundThe Oxford Shoulder Score (OSS) and the Shoulder Pain and Disability Index (SPADI) are patient-based outcome scores with valid psychometric properties which are widely used for shoulder interventions.ObjectiveThe purpose of the study is to adapt both questionnaires cross-culturally to Spanish, and to test their reliability, validity, responsiveness, and feasibility.DesignCultural adaptation and psychometric validation study.MethodsConsecutive patients who had undergone breast cancer surgery referred to an outpatient clinic at the University of Alcalá de Henares, Spain. One hundred and twenty women who had undergone breast cancer surgery, with pain and shoulder dysfunction. Cross-cultural adaptation was performed according to the international guidelines. Reliability was analysed by test-retest reliability and internal consistency. Content and convergent construct validity were measured by the Expert Committee’s and Spearman coefficient respectively. Responsiveness, feasibility, floor and ceiling effects were also tested.ResultsOne hundred and twenty women aged 54.2 (±11) years took part in the study. The reliability was excellent; test-retest reliability was 0.974 (p < 0.001) for OSS, and 0.992 (p < 0.001) for SPADI; and Cronbach’s alpha value was 0.947 for OSS, and 0.965 for SPADI. High construct validity was found between the OSS and SPADI questionnaires (r = −0.674). The effect size (ES) and standardized response mean (SRM) was moderate in OSS (ES = 0.50 and SRM = 0.70 (p < 0.001)), and moderate to good in SPADI (ES = 0.59 and SRM = 0.82 (p < 0.001)).LimitationsThis study has some limitations, such as the group of participants is composed only of women following breast cancer treatment; the measurement took place in a single centre; and all the questionnaires administered were always provided to the participants in the same order.ConclusionsThe OSS and SPADI Spanish versions are applicable, reliable, valid, and responsive to assess shoulder symptoms and quality of life in Spanish women with shoulder pain and disability after breast cancer treatment.Electronic supplementary materialThe online version of this article (doi:10.1186/s12955-015-0256-y) contains supplementary material, which is available to authorized users.

Objective: Several muscles surrounding neck are vital not only for neck motion, but for upper extremities motions as well. Neck pain would affect neck and shoulder disability. The Neck Disability Index (NDI), Shoulder Pain and Disability Index (SPADI), and Visual Analogue Scale (VAS) are increasingly used to evaluate treatment effectiveness after chronic neck pain. The purpose of this study was to analyze the correlation of neck pain, shoulder pain, and quality of life in patients with chronic neck pain. Design: Cross-sectional study. Methods: Forty-three patients with neck pain participated in this study. Participants were instructed to place a mark on each item of three clinical measures that best represented their experience of his/her neck and shoulder problem over the last week. The outcome measures of the study were NDI, SPADI, and VAS for neck and shoulder pain and disability. Results: The NDI was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The VAS-Neck was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI- Total, and VAS-Shoulder (p<0.05). The SPADI-Total was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI- Disability, and VAS-Shoulder (p<0.05). The SPADI-Pain was significantly correlated with the NDI, VAS-Neck, SPADI- Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Disability was significantly correlated with the NDI, VAS- Neck, SPADI-Total, SPADI-Pain, and VAS-Shoulder (p<0.05). The VAS-Shoulder was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and SPADI-Total (p<0.05). Conclusions: Neck disability in patients with chronic neck pain should be considered with disability and pain of the shoulder.

Shoulder Pain and Disability Index (SPADI)

To evaluate the psychometric properties of self-administered patient-reported outcome (PRO) questionnaires which were used in non-surgical homogeneous populations with musculoskeletal shoulder disorders. The included studies were identified using eligibility criteria. The methodological quality of each article was assessed using the COSMIN checklist. The psychometric properties of original versions and translated versions of PROs were also assessed. Twenty articles were included. Two musculoskeletal shoulder disorders were identified that met the selection criteria: rotator cuff disease and glenohumeral instability. A total of 11 PROs were identified. In general, the methodological quality of the included studies is fair or poor. The Western Ontario Rotator Cuff Index (WORC) and the Shoulder Pain and Disability Index (SPADI) are the most frequently evaluated PROs for patients with rotator cuff disease, and their psychometric properties seem to vary according to what language that they are in. For glenohumeral instability, the Western Ontario Shoulder Instability Index (WOSI) and the Oxford Instability Shoulder Score (OISS) are the most frequently evaluated PROs, and their psychometric properties seem to be adequate. Using for rotator cuff disease is advised, for Norwegian users, the SPADI, WORC, Oxford Shoulder Score, and disabilities of the arm, shoulder and hand. Dutch and Persian users could use the WORC. For Greek speakers, the SPADI is recommended. Turkish users could use the rotator cuff quality-of-life measure. For glenohumeral instability, Dutch and Norwegian speakers could use the WOSI and the OISS. Italian, Japanese, and Turkish users could use the WOSI. For English users, the OISS and the Shoulder Rating Questionnaire are recommended. III.

The literature emphasizes that a consideration of patients' perspectives is an important part of the assessment process; however, it is ignored by many clinicians because they believe physical impairment measures can reflect patients' perspectives about their symptoms. But the relevance of changes in physical impairments to changes in patient-reported outcome scores in rotator cuff disease is ambiguous. The purpose of this study is to determine the relationship between changes in glenohumeral range of motion (ROM) and shoulder muscle strength and changes in pain, disability, and health-related quality of life scores before and after physical therapy in patients with rotator cuff disease. This was a retrospective study of thirty-nine patients with unilateral rotator cuff disease. All patients received a 6-week physical therapy program. The outcome measures were glenohumeral ROM, shoulder muscle strength, pain and disability using the Shoulder Pain and Disability Index (SPADI), and health-related quality of life as measured by the Western Ontario Rotator Cuff Index. All outcomes were measured before and after the treatment period. There were weak correlations between the changes in abduction ROM and the SPADI-total score (r = - 0.32, p < 0.05), and the changes in external rotation strength and the SPADI-disability score (r = - 0.32, p < 0.05). There was no correlation between the changes in the other parameters. This study implies that the changes in glenohumeral ROM and shoulder muscle strength do not represent the changes in patients' perspectives in pain, disability, and health-related quality of life after the physical therapy program in patients with rotator cuff disease.
