Assessment of Cross-Cultural Adaptations and Patient-Reported Outcome Measures Relevant To Shoulder Disorders in Turkish: a Systematic Review Using the Cosmin Methodology
(Public Library Science, 2025) Isiklar, Cagdas; Sirma, Gamze Cagla; Turgut, Elif
Background There are many shoulder assessment outcome measures in the literature that have been studied for validity and reliability. However, there is no study examining the Turkish-adapted patient outcome measures (PROMs) on the shoulder according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist. In addition, there is a small number of studies that carry out this examination on the shoulder internationally. Determining the most appropriate questionnaires for clinical use will also be an important guide in patient evaluation by filling the gap in both literature and clinical aspects.Objective Our aim in this study is to identify the valid and reliable Turkish scales used to evaluate shoulder pain and disability, to reveal how compatible these scales are with the aspects of study quality and psychometric quality according to COSMIN criteria list.Methods A systematic search was performed in the following electronic databases: MED-LINE, Web of Science (WOS), EMBASE, SCOPUS, and ULAKBIM were searched from inception to September 2024.Results A total of 2890 articles were found in the databases. Four articles were included additionally without a search. Then, after eliminating the duplicates, 2231 articles were included based on the title and abstract search. 63 articles were included in full-text review. After the full-text review, according to our criteria, 29 articles were included in the systematic review. According to the assessment by the COSMIN checklist, 28 articles received the final classification of "inadequate". Only 1 article (UCLA-Tr) received the final classification of "adequate".Conclusion There is a wide range of Turkish PROMs available for the shoulder, with only one fully meeting COSMIN methodology criteria. However, this does not imply that other PROMs lack clinical utility. Future studies should focus on refining PROMs by incorporating MCID and PASS scores and prioritizing their responsiveness to enhance their clinical relevance. Additionally, variations in PROM performance across different patient populations highlight the need for context-specific evaluations to ensure their applicability in diverse clinical settings.Trial registration PROSPERO registration number: CRD42022298425.
Shoulder Muscular Activation during Common Kettlebell Exercises: A Randomized Cross-Sectional Surface EMG Study
(Taylor & Francis Inc, 2026) Paköz, Büşra; Işiklar, Çağdaş; Turgut, Elif
Purpose This study aimed to examine shoulder muscle activation patterns within functionally similar upper-body exercise categories performed using different resistance modalities. Methods Twenty healthy males (mean age 22.6 +/- 1.69 years) performed overhead pressing, rowing, and swinging tasks using kettlebells, dumbbells, and elastic bands. Surface electromyography (EMG) was used to record activity from seven shoulder muscles. The recorded electromyographic signals were normalized to maximal voluntary isometric contractions (%MVIC), log-transformed, and analyzed using a two-way repeated-measures analysis of variance (ANOVA) with exercise and muscle as within-subject factors. Results A repeated-measures ANOVA on log-transformed EMG data showed significant main effects of exercise (F(2.10, 39.95)=22.04, p<.001, eta(2) p=.537) and muscle (F(4.49, 85.34)=47.55, p<.001, eta(2) p=.714), as well as a significant exercise & times;muscle interaction (F(8.16, 154.98)=82.84, p<.001, eta(2) p=.813). Within the overhead pressing category, the Bottoms-Up Kettlebell Overhead Press elicited significantly greater activation than the traditional Kettlebell Overhead Press in the upper trapezius, lower trapezius, biceps brachii, and infraspinatus (all p<.050), with upper trapezius activation reaching 30.4 +/- 13.4%MVIC. In the rowing category, middle and lower trapezius activation was greater during free-weight rowing than during elastic band rowing, while serratus anterior activation remained relatively low across the rowing conditions. In the swing category, activation patterns were largely comparable between the two-hand kettlebell and dumbbell swings, whereas the one-hand kettlebell swing produced greater activation in selected muscles, with the lower trapezius showing the highest activation. Absolute between-exercise differences in %MVIC were modest. Conclusion Kettlebell, dumbbell, and elastic band exercises elicit distinct shoulder muscle activation profiles. These findings may inform exercise selection and program design when targeting specific shoulder muscles within task-oriented training contexts.
