Öğe Carpal tunnel syndrome prediction with machine learning algorithms using anthropometric and strength-based measurement(Public Library of Science, 2024) Yetiş, Mehmet; Kocaman, Hikmet; Canlı, Mehmet; Yıldırım, Hasan; Yetiş, Aysu; Ceylan, İsmailObjectives Carpal tunnel syndrome (CTS) stands as the most prevalent upper extremity entrapment neuropathy, with a multifaceted etiology encompassing various risk factors. This study aimed to investigate whether anthropometric measurements of the hand, grip strength, and pinch strength could serve as predictive indicators for CTS through machine learning techniques. Methods Enrollment encompassed patients exhibiting CTS symptoms (n = 56) and asymptomatic healthy controls (n = 56), with confirmation via electrophysiological assessments. Anthropometric measurements of the hand were obtained using a digital caliper, grip strength was gauged via a digital handgrip dynamometer, and pinch strengths were assessed using a pinchmeter. A comprehensive analysis was conducted employing four most common and effective machine learning algorithms, integrating thorough parameter tuning and cross-validation procedures. Additionally, the outcomes of variable importance were presented. Results Among the diverse algorithms, Random Forests (accuracy of 89.474%, F1-score of 0.905, and kappa value of 0.789) and XGBoost (accuracy of 86.842%, F1-score of 0.878, and kappa value of 0.736) emerged as the top-performing choices based on distinct classification metrics. In addition, using variable importance calculations specific to these models, the most important variables were found to be wrist circumference, hand width, hand grip strength, tip pinch, key pinch, and middle finger length. Conclusion The findings of this study demonstrated that wrist circumference, hand width, hand grip strength, tip pinch, key pinch, and middle finger length can be utilized as reliable indicators of CTS. Also, the model developed herein, along with the identified crucial variables, could serve as an informative guide for healthcare professionals, enhancing precision and efficacy in CTS prediction. © 2024 Yetiş et al.

The objective of this study was to identify the possible predictors of pain intensity in non-surgically treated adults with IS. Methods This cross-sectional study included 58 adults individuals with Lenke type 1 IS. Participants' sociodemographic characteristics were recorded, and pain severity, curvature severity, trunk rotation angle, disability, spinal mobility, cosmetic deformity perception, and quality of life were assessed. Regression analyses with various models were performed to determine the predictors of pain severity and the best model was selected based on performance criteria. Results Strong associations were found between pain severity with curvature severity, spinal mobility, trunk rotation angle, perception of cosmetic deformity, disability, and quality of life (p < 0.05). It was observed that Lasso regression was the best model based on the performance criteria considered. According to this model, the primary predictors of pain intensity in adult IS were determined as curvature severity, spinal mobility, trunk rotation angle, cosmetic deformity perception, back-related disability and quality of life, in order of importance. Conclusion In accordance with the findings of this study, which examined for the first time the determinants of pain intensity in adult individuals with Lenke type 1 IS, we suggest that mentioned possible factors affecting and determining pain should be taken into consideration when establishing evaluation and treatment programs.Öğe The effectiveness of two different exercise approaches in adolescent idiopathic scoliosis: A single-blind, randomized-controlled trial(Public Library of Science, 2021) Kocaman, Hikmet; Bek, Nilgün; Kaya, Mehmet Hanifi; Büyükturan, Buket; Yetiş, Mehmet; Büyükturan, ÖznurObjectives The purpose of this study was to compare the efficacy of two different types of exercise methods in patients with adolescent idiopathic scoliosis. Methods In total, 28 subjects with adolescent idiopathic scoliosis with a mild curve magnitude (10°-26°) were randomly divided into two groups: The Schroth group (n = 14) and the core group (n = 14). The patients in the Schroth group were treated with supervised Schroth exercises, and the patients in the core group were treated with supervised core stabilization exercises; both groups performed the exercises for three days per week for a total of 10 weeks, and both were given additional traditional exercises to perform. Assessment included Cobb angle (Radiography), trunk rotation (Adam's test), cosmetic trunk deformity (Walter Reed Visual Assessment Scale), spinal mobility (Spinal Mouse), peripheral muscle strength (Biodex System 4-Pro), and quality of life (Scoliosis Research Society-22 questionnaire). Results It was found that patients in the Schroth group showed greater improvement in Cobb angles, thoracic trunk rotation angle, cosmetic trunk deformity, spinal mobility, and quality of life than those in the core group (p<0.05), except for in lumbar trunk rotation angle. Peripheral muscle strength improvement was greater in the core group than in the Schroth group (p<0.05). Conclusion Schroth exercises are more effective than core stabilization exercises in the correction of scoliosis and related problems in mild adolescent idiopathic scoliosis, and core stabilization exercises are more effective than Schroth exercises in the improvement of peripheral muscle strengthÖğe Factors Associated with Upper Extremity Functionality After Mini-Open Release Surgery for Treatment of Carpal Tunnel Syndrome(2024) Yetiş, Mehmet; Canlı, Mehmet; Kuzu, Şafak; Valamur, İrem; Kocaman, Hikmet; Yıldız, Nazım Tolgahan; Özüdoğru, AnılAim: The objective of this study was to investigate the correlation between upper extremity functionality, pain intensity, muscle strength, and symptom severity among patients diagnosed with carpal tunnel syndrome (CTS) who underwent mini-open release surgery. Material and Method:This retrospective study entailed the review of medical records of 70 patients diagnosed with CTS who underwent mini-open release surgery between January 2021 and January 2023. Data were collected from preoperative assessments and routine follow-up evaluations conducted at 3 months post-surgery. Upper extremity functionality was assessed utilizing the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire, pain severity was determined using the Visual Analog Scale (VAS), muscle strength was evaluated through hand grip strength, and disease severity was measured using the Boston Carpal Tunnel Questionnaire (BCTQ). Results: A statistically significant improvement was observed in DASH questionnaire scores, VAS scores, hand grip strength, and BCTQ scores at the 3-month follow-up compared to preoperative values (p<0.05). Furthermore, significant correlations were found between DASH questionnaire scores and VAS scores, hand grip strength, and BCTQ scores during postoperative assessments (p<0.05). Conclusion: Mini-open-release surgery demonstrates effectiveness as a surgical approach for achieving favorable clinical outcomes in patients with CTS. Furthermore, our findings suggest that postoperative upper extremity functionality may be influenced by factors such as pain intensity, symptom severity, and hand grip strength. Therefore, we advocate for the integration of these factors into postoperative patient evaluation protocols and treatment programs to optimize patient outcomes.Öğe Validity and reliability of the modified four square step test in individuals with ankle sprain(BioMed Central Ltd., 2024) Yetiş, Mehmet; Kocaman, Hikmet; Canli, Mehmet; Yıldırım, Hasan; Yıldız, Nazım TolgahanBackground: Postural instability and gait abnormalities are frequently observed after an ankle sprain. A modified Four Square Step Test (mFSST) was developed to assess dynamic balance during gait. The aim of this study was to evaluate the reliability and validity of the mFSST in individuals with ankle sprains. Methods: The study included 39 individuals with grade 1 and 2 ankle sprains with a mean age of 30.36 ± 6.21 years. The dynamic balance of the participants was assessed with the mFSST and Timed Up & Go test (TUG). To determine the test-retest reliability of the mFSST, the test was repeated approximately 1 h apart. Results: The test-retest reliability of the mFSST was excellent (ICC = 0.85). Furthermore, when the concurrent validity of the mFSST was examined, a high correlation was found between with the TUG (r = 0.78, p < 0.001). Conclusion: The mFSST is a valid and reliable clinical assessment method for evaluating dynamic balance during walking in individuals with ankle sprains. We think that the mFSST is preferable in clinical evaluations because its platform is easy to prepare and requires very little equipment.
