Prediction of disability in trigger finger: a cross-sectional and longitudinal study
(2023) Namaldi, Seda; Kuru, Cigdem Ayhan; Kuru, Ilhami; 36324191
The aim of this prospective study of 55 patients was to analyse the cross-sectional and longitudinal relationship between disability and physical and psychological variables after conservative treatment of trigger finger and to determine the predictive factors for the post-treatment disability score and change in disability score. The primary outcome measure was the Disabilities of the Arm, Shoulder, and Hand questionnaire. Potential predictive factors included pain, number of triggering events, depression, anxiety and kinesiophobia. Disability correlated strongly with anxiety, moderately with pain and depression and weakly with triggering and kinesiophobia. The change in depression score correlated significantly with the change in disability score. Post-treatment pain and anxiety scores accounted for 47% of the explained variance in disability score. Improvement in depression after treatment accounted for 18% of the explained variance in disability change score. Psychological variables appear to be potential predictors of disability.
Responsiveness and Validity of Weight-Bearing Test for Measuring Loading Capacity in Patients With Triangular Fibrocartilage Complex Injury
(2022) Kuru, Cigdem Ayhan; Uysal, Ozgun; Karaca, Nur Banu; Akar, Zeliha; Ayhan, Egemen; Kuru, Ilhami; 35461186
Context: Weight-bearing test (WBT) is a noninvasive quantitative test which has been used recently to determine loading capability of the individuals. The aim of this study was to strengthen the evidence for using the WBT test for measuring weight -bearing capacity of the upper-extremity with the specific objective of examining the internal and external responsiveness and concurrent validity of the test in patients with triangular fibrocartilage complex injury. Design: Single-group repeated measures.Methods: Internal responsiveness was assessed using effect size statistics. The correlation coefficient was used to examine external responsiveness by testing 5 hypotheses regarding predefined correlations between the changes in the measurements. Concurrent validity was evaluated by analyzing correlations between the WBT and other measurements. Thirty-one patients with triangular fibrocartilage complex injury were included for the analysis of the concurrent validity. Eighteen patients who completed all measurements at baseline and at 3-month follow-up enrolled for the responsiveness analysis. Measurements included the WBT, pain intensity, grip strength, and upper extremity functional level.Results: The WBT test was able to detect statistically significant changes in weight-bearing capacity between baseline and follow-up (P = .0001). The effect size of the WBT was large. Three out of 5 hypotheses (60%) were confirmed, a good correlation was found between changes scores of the WBT and grip strength (r = .478; P < .05). There were significant correlations between the WBT and other measurements (r value range from -.401 to .742; P < .05). A higher correlation was found between the WBT and grip strength (r= .742; P = .0001).Conclusions: The responsiveness and concurrent validity of the WBT test confirmed that it is able to measure change in weight -bearing capacity in patients with triangular fibrocartilage complex injury.
Use of Generalizability Theory Evaluating Comparative Reliability of the Scapholunate Interval Measurement With X-ray, CT, and US
(2023) Kuru, Cigdem Ayhan; Sezer, Rahime; Cetin, Can; Haberal, Bahtiyar; Yakut, Yavuz; Kuru, Ilhami; 0000-0003-3173-1757; 0000-0003-4613-1607; 0000-0002-1668-6997; 36604227; W-9080-2019
Rationale and Objectives: There is no universally accepted standard technique for measuring the scapholunate interval and no specific sources of measurement error have been identified. We aimed to establish a set of normal radiological criteria for the scapholunate interval that could be used in comparative studies of wrist pathology to determine interobserver reliability and to identify potential errors that might influence measurements.Materials and Methods: A total of 60 healthy volunteers participated in the study. Scapholunate interval was measured by three independent observers using X-ray, CT, and US in four positions, including neutral, fist, radial and ulnar deviation. Inter-observer reliability was tested using intraclass correlation coefficient. Generalizability theory was applied to evaluate specific sources of measurement error related to participant, observer, imaging modality and measurement position.Results: In neutral position, the scapholunate interval measured by X-ray, CT, and US was 3.1 mm, 3.5 mm and 3.5 mm respectively. The interval remained constant during fist and radial deviation but decreased during ulnar deviation. Correlation coefficients ranged from 0.874 to 0.907 for X-ray, 0.773-0.881 for CT and 0.964-0.979 for US. In the generalizability study, the participant x modality x position interaction accounted for the largest proportion of total variance (29%).Conclusion: X-ray, CT, and US are reliable modalities for measuring the scapholunate interval, with US having the highest reliability. Participant and position factors may independently contribute to measurement error. Therefore, standardized measurement positions are recommended to obtain reliable measurement results.
