“…In addition, the advantage of rotator-cuff measures has not been proven to date in the shoulder-related literature. [19][20][21] Although the main value of the multiple-domain measures is in their ability to document the impact of disease on each QOL domain, we do not have supporting evidence for the specificity of information from each domain or sub-scale. 22,23 Several other shortcomings specific to the WORC can be noted.…”

Purpose: The objective of this study was to develop and examine the measurement properties of a shortened version of the Western Ontario Rotator Cuff Index (WORC), the SHORTWORC, in individuals with rotator-cuff pathology. Methods: The study occurred in two stages, both using secondary analysis of existing data sets. The first stage used cross-sectional data from candidates for rotator-cuff surgery to develop the SHORTWORC. The second stage examined various measurement properties of the SHORTWORC by analyzing scores from the WORC, the American Shoulder and Elbow Surgeons questionnaire, and the Constant-Murley score obtained from patients before and after rotator-cuff surgery. Approaches to validating the SHORTWORC included calculating the standard error of measurement (SEM) at an instant in time, performing a confirmatory factor analysis, correlating findings among the questionnaires, and examining differences between men and women. Sensitivity to change was investigated using standardized response mean and relative efficiency. Results: Data for 712 patients were used to develop the SHORTWORC, the final version of which consisted of 7 questions. Data for 166 patients (86 men, 80 women; mean age 57 e 11 years) were used for validation. The SEM based on internal consistency (SEM IC ) was calculated as 7.43 SHORTWORC points. The SHORTWORC had similar convergent validity (r ¼ 0.72 À 0.82) and sensitivity to change (SRM ¼ 1.20 vs. 1.25, p > 0.05) to the longer version. The relative efficiency of the SHORTWORC was 3.19 times that of the WORC (95% CI, 1.50-71.51) in discriminating men's from women's level of disability. Conclusions: The SHORTWORC has indicators of validity, relative efficiency, and sensitivity to change comparable to those of the original version but has a smaller response burden.Key Words: outcome measures; reliability of results; shortened version; validity of results; WORC.

“…2 The Upper Extremity Functional Index (UEFI) is a patient-reported outcome measure (PROM) for quantifying UE function 3 that has been used in several studies of people with musculoskeletal UE problems. [4][5][6][7][8] Recently, we performed a Rasch analysis of the tool that informed its modification to a 15-item interval-level PROM (UEFI-15). 9 Psychometric properties of the UEFI-15 have not been compared to the original version, nor has the positive minimal clinically important difference (pMCID) been determined for either measure.…”

Purpose: To examine the reliability, validity, and sensitivity to change of the 20-item version and the Rasch-refined 15-item version of the Upper Extremity Functional Index (UEFI-20 and UEFI-15, respectively) and to determine the impact of arm dominance on the positive minimal clinically important difference (pMCID). Methods: Adults with upper-extremity (UE) dysfunction completed the UEFI-20, Upper Extremity Functional Scale (UEFS), Pain Limitation Scale, and Pain Intensity Scale at their initial physiotherapy assessment (Time 1); 24-48 hours later (Time 2); and 3 weeks into treatment or at discharge, whichever came first (Time 3). Demographics, including working status, were obtained at Time 1. Global ratings of change (GRC) were provided by the treating physiotherapist and patient at Time 3. The UEFI-15 was calculated from relevant items in the UEFI-20. The intra-class correlation coefficient (ICC) and minimal detectable change (MDC) quantified test-retest reliability (Time 1-Time 2). Cross-sectional convergent validity was determined by the association (Pearson's r) between Time 1 measures of function and pain. Known-groups validity was evaluated with a one-way ANOVA across three levels of working status. Longitudinal validity was determined by the association (Pearson's r) between function and pain change scores (Time 1-Time 3). Receiver operating characteristic (ROC) curves estimated the pMCID using Time 1-Time 3 change scores and average patient/therapist GRC. Results: Reliability for the UEFI-20 and UEFI-15 was the same (ICC ¼ 0.94 for both measures). MDC values were 9.4/80 for the UEFI-20 and 8.8/100 for the UEFI-15. Crosssectional, known-groups, and longitudinal validity were confirmed for both UEFI measures. pMCID values were 8/80 for the UEFI-20 and 6.7/100 for the UEFI-15; pMCID was higher for people whose non-dominant arm was affected. Conclusions: Both UEFI measures show acceptable reliability and validity. Arm dominance affects pMCID. The UEFI-15 is recommended because it measures only one dimension: UE function.

“…Therefore, a method such as SF-36, used to evaluate general daily life activity, was not used in the present study. A study comparing the Rotator Cuff-Quality of Life (RC-QOL) with WORC index as well as with other scales indicated that both forms were quite sensitive in determining alterations in patients with rotator cuff lesions (24). Holtby et al (25) compared the ConstantMurley Form, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and WORC Index Form for evaluating patients with shoulder pain and they reported a strong correlation between them.…”

Objective: In this study, we aimed to compare the clinical effect of landbased and water-based exercise programs in patients with subacromial impingement syndrome. Materials and Methods: Seventy shoulders were randomized to waterbased (n=35) or land-based (n=35) exercise program. The intervention in the water-based exercise group consisted of hot pack, transcutaneous electrical nerve stimulation (TENS), ultrasound (US) and exercise in the water; and in the land-based exercise group, consisted of hot pack, TENS, US and land-based exercises. The measurement was performed after the treatment and 3 months after the beginning of the treatment. We used visual analog scale (VAS) for pain assessment and shoulder function was measured with the Shoulder Pain and Disability Index and the Western Ontario Rotator Cuff Index. Results: Patient demographics and baseline values were similar for both groups. The pain reduction in both groups was statistically significant at the first follow-up. A significant reduction in pain at second follow-up was observed in the water-based exercise group compared with the land-based exercise group. We found statistically significant recuperation in both groups for functional index and more recuperation in the water-based exercise group at the second follow-up. Conclusion: A greater improvement in pain and functional capacity was achieved with combination of physical therapy and water-based exercise program in patients with subacromial impingement syndrome.

Key Words: Exercise therapy, aquatic rehabilitation, shoulder pain Özet Amaç: Bu çalışmamızda omuz subakromiyal sıkışma sendromlu hastalarda kara egzersizleri ile su içi egzersizlerin etkinliğini karşılaştırmayı amaçladık. Gereç ve Yöntem: Çalışmaya her iki grupta 35 olmak üzere, toplam 70 omuz alındı. Hastalar 2 gruba randomize edildi. Kara egzersiz grubuna (n=35) sıcak paket + transkütanöz elektiriksel sinir stimulasyonu (TENS) + ultrason (US) + kara egzersizleri, su içi egzersiz grubuna (n=35) sıcak paket + TENS + US + su içi egzersiz tedavileri uygulandı. Hastalar tedaviden hemen sonra ve 3. ayda değerlendirildi. Değerlendirme ölçümlerinde ağrı için görsel analog skala, fonksiyonel durum için ise Shoulder Pain and Disability İndex ve Western Ontario Rotator Cuff İndeksleri kullanıldı. Bulgular: Çalışmaya alınan hastaların her iki grupta da tedavi öncesinde demografik ölçümleri benzerdi. Hastaların tedaviden hemen sonraki ilk kontrolünde ağrı şiddetinde istatistiksel olarak anlamlı azalma her iki grupta da gözlendi. 3. aydaki ikinci kontrolde ise su içi egzersiz grubunda ağrı şiddetindeki azalmanın daha fazla olduğu kaydedildi. Her iki grupta da ilk kontrolde omuzun fonksiyonel durumunu değerlendirmeye yönelik skalalarda istatistiksel olarak anlamlı düzelme kaydedildi, ikinci kontrolde bu düzelmenin su içi egzersiz grubunda daha fazla olduğu gözlendi. Sonuç: Omuz subakromiyal sıkışma sendromlu hastalarda, fizik tedavi ajanları ile su içi egzersiz programının kombinasyonu; ağrı ve fonksiyonel kapasite...
