Öğe An investigation of machine learning algorithms for prediction of temporomandibular disorders by using clinical parameters(Lippincott Williams & Wilkins, 2024) Yıldız, Nazım Tolgahan; Kocaman, Hikmet; Yıldırım, Hasan; Canlı, MehmetThis study aimed to predict temporomandibular disorder (TMD) using machine learning (ML) approaches based on measurement parameters that are practically acquired in clinical settings. 125 patients with TMD and 103 individuals without TMD were included in the study. Pain intensity (with visual analog scale), maximum mouth opening (MMO) and lateral excursion movements (with millimeter ruler), cervical range of motion (with goniometer), pressure pain threshold (PPT; with algometer), oral parafunctional behaviors (with Oral Behaviors Checklist), psychological status (with Hospital Anxiety and Depression Scale), and quality of life (with Oral Health Impact Profile) were evaluated. The measurements were analyzed via over 20 ML algorithms, taking into account an extensive parameter tuning and cross-validation process. Results of variable importance were also provided. Bagging algorithm using Multivariate Adaptive Regression Spline (MARS) algorithm (accuracy = 0.8966, area under receiver operating characteristic curve = 0.9387, F1-score = 0.9032) was the best performing model regarding the performance criteria. According to this model, the 5 most important variables for predicting TMD were pain intensity, MMO, lateral excursion and PPT values of masseter and temporalis anterior muscles, respectively. The Bagging algorithm using the MARS algorithm is a robust model that, in combination with clinical parameters, assists in the detection of patients with TMD in settings with limited capabilities. The clinical parameters and ML algorithm proposed in this study may assist clinicians inexperienced in TMD to make a preliminary detection of TMD in clinics where diagnostic imaging tools are limited.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.

Method: Forty individuals with CNP were included in the study and randomly divided into two groups: the cervical stabilization group (SG, n=20) and the cervical stabilization-Mulligan mobilization group (SMG, n=20). The SG group only received cervical stabilization exercises for four weeks, while the SMG received Mulligan mobilization techniques for four weeks in addition to cervical stabilization exercises. Before and after the treatment programs, the subjects were evaluated in terms of pain intensity (visual analogue scale), ROM (goniometric measurement), cervical muscle endurance (endurance tests), PPT (algometric measurement), and quality of life (Short Form-36, SF-36). Results: Significant improvements were found in all parameters in both groups after the treatment programs (p<0.05). In addition, there were more improvements in ROM, PPT, and SF-36 scores in SMG compared to SG (p<0.05). Conclusion: The application of cervical stabilization exercises in CNP may improve pain intensity, ROM, cervical muscle endurance, PPT, and quality of life. However, it can be said that Mulligan mobilization techniques applied in addition to cervical stabilization exercises are more effective in improving ROM, PPT, and quality of life compared to cervical stabilization exercises alone in individuals with CNP.Öğe Comprehensive analysis of muscles wasting in disc herniation(Elsevier Ltd., 2022) Gökşen, Ayşenur; Kocaman, Hikmet; Merve Arman, Gökçe; Lütfi Selçuk, MuhammetNeuromuscular reeducation of the muscles that stabilize the spine is the basis of conservative treatment of disc herniation. Therefore, it is important to investigate how these muscles are affected by disc herniation. The aim of this study was to investigate the effect of disc herniation, herniation severity, patient age, and biomechanics on the lumbar stabilizer muscles. A total of 330 individuals, including 261 patients with disc herniations and 69 without disc herniation participated in this study. The cross-sectional areas (CSAs) of the lumbar stabilizer muscles and the lumbar lordosis angle were evaluated by magnetic resonance imaging (MRI), according to the severity of the disc herniation and the patient's age. In the patients with disc herniation, the CSAs of the quadratus lumborum (QL) and the multifidus (MF) muscles were decreased. The psoas major (PM) muscle CSA was higher in the patients with sequestered discs than in those with protruded and extruded discs. A negative relationship between the sagittal curve and the PM muscle CSA was found. In addition, MF muscle CSA was found to decrease at age 45 years and over. Although disc herniation negatively affects muscle CSAs, no linear relationship was found between the severity of the herniation and the muscle CSA. In addition, the PM muscle was found to be a strong compensatory muscle in disc herniation.Öğe Could There Be a Relationship Between Paranasal Sinus and Migraine Etiology?(2024) Payas, Ahmet; Göktürk, Şule; Göktürk, Yasin; Koç, Ali; Tokpınar, Adem; Kocaman, HikmetAim: Migraine is a complex neurological disease with a neurogenic inflammatory component in which nitric oxide (NO) levels increase. Studies have shown that the NO level produced in adults is closely related to the paranasal sinus volume. The aim of this study is to investigate the differences in paranasal sinus volumes responsible for NO synthesis in migraine patients. Material and Method: The paranasal sinuses of migraine patients (n=50) and healthy subjects (n=50) were examined using cranial T1-weighted magnetic resonance images (MRI). Right and left maxillary, sphenoid and frontal-ethmoid sinus volumes of the groups were calculated in 3D Slicer program and recorded in mm3. Statistical analysis of the study was performed with IBM SPSS 23.0 and p<0.05 values were considered significant. Results: A statistically significant difference was observed between migraine patients and healthy subjects across all sinus volumes, with the sinus volumes of migraine patients being higher than those of healthy subjects (p<0.05). Conclusion: We think that the fact that the paranasal sinus volume, which is primarily responsible for NO synthesis, was found to be high in migraine patients may be related to the high NO level in migraine patients.Öğe COVID-19 and postural sway: a comparison of individuals with a SARS-CoV-2 history and healthy sedentary women(Guilford Press, 2023) Kocaman, Hikmet; Soslu, Recep; Gökşen, Ayşenur; Uysal, AbdullahPurpose: The aim of the study was to evaluate the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postural sway in subjects who have recently recovered from infection. Materials and methods: Fifty-six female individuals with a mild to moderate history of SARS-CoV-2 (n = 25, mean age; 21.13 ± 0.64 years) and healthy sedentary controls (n = 31, mean age; 20.09 ± 1.05 years) were included in the study. Postural sway tests were performed in double and single-leg stance on a force plate with eyes open before and after the neuromuscular fatigue test. The Wingate test was used to induce neuromuscular fatigue. To evaluate the change of the variables determined by the measurements of the groups over time and the group-time interactions, a two-way analysis of variance in repeated measures (mixed design repeated measures ANOVA) was used. Results: It was found that the SARS-CoV-2 group showed increased total sway path, velocity, and area than those in the healthy group on double and single-leg (right-left) stance (p < 0.05). Conclusions: Even if SARS-CoV-2 group individuals have been reported in a mild to moderate outpatient COVID-19 process, they showed deterioration in postural control compared to healthy individuals. In addition, it was found that SARS-CoV-2 accelerated neuromuscular fatigue effects. This can cause more fatigue during activities than individuals who have not had SARS-CoV-2.Öğe Cross-cultural adaptation, reliability, and validity of the Turkish version of the Cumberland Ankle Instability Tool(Elsevier, 2023) Candeniz, Seyda; Kocaman, Hikmet; Celik, Seher Erol; Bek, NilguenObjectives: The objective of the study was to cross-culturally adapt and assess the validity and reliability of the Turkish version of the CAIT (CAIT-TR).Methods: The CAIT was translated and adapted into Turkish according to accepted cross-cultural adaptation guidelines of self-reported measures. A total of 130 individuals, including healthy participants (n = 40) and with chronic ankle instability (CAI) (n = 90), were recruited in this study. The internal consistency and test-retest reliability of the CAIT-TR were assessed using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. To assess convergent validity, hypotheses were tested regarding expected correlations between CAIT-TR, Foot and Ankle Outcome Score (FAOS) subscales, and the Visual Analogue Scale (VAS). Discriminative validity was evaluated with the hypothesis that the CAIT-TR can distinguish between subjects with and without CAI and also calculated a cut-off score for CAI. The dimensional structure of the CAIT-TR was investigated with confirmatory factor analysis. Additionally, minimal detectable change (MDC), floor/ceiling effects, and measurement error values were determined.Results: The CAIT-TR demonstrated high Internal consistency (Cronbach's alpha = 0.854) and test-retest reliability (ICC = 0.919). Regarding convergent validity, the CAIT-TR exhibited a moderate-strong correlation with both the FAOS and VAS. The confirmatory factor analysis supported the unidimensional structure of the questionnaire. The identified cut-off value for the CAIT-TR was 25, and the MDC for individual-level CAIT-TR scores was determined to be 1.87. No floor or ceiling effects were observedConclusion: The CAIT-TR is a valid and reliable questionnaire for the assessment of ankle instability within the Turkish population.Öğe Determinants of Parental Satisfaction with Rehabilitation Service Delivery to Children with Childhood-Onset Physical Disabilities: A Turkish Sample(2024) Bingöl, Hasan; Yıldız, Nazım Tolgahan; Kocaman, HikmetAim: Studies have demonstrated that family centeredness, or family involvement in decision-making and care provision, is crucial for achieving the best results in pediatric rehabilitation and is also directly associated to parental/caregiver satisfaction with rehabilitation services. This study aimed to explore the potential determinants of parents’/caregivers’ satisfaction with rehabilitation services based on the various elements of family centeredness. Material and Method: Authors included the parents/caregivers of 120 children with physical disabilities aged 5-18 years (mean 10.14 years, SD 4.17). The Measure Process of Care-20 (MPOC-20) was used to assess parents'/caregivers' perceptions of the family centeredness in provision of rehabilitation services and therefore parental/caregiver satisfaction with rehabilitation service delivery to children. Results: Service-related and child-related factors accounted for 78% and 67% of the variances in the parents’/caregivers’ satisfaction with being provided opportunities for them to make decisions about rehabilitation services (MPOC-20-Enabling and Partnership subscale), respectively. Parental/caregiver satisfaction with service delivery in the context of sharing information about child’s progress was correlated with service-related, child-related, and parent/caregiver-related factors (adjusted R2=0.75, 0.71, and 0.68, respectively). Satisfaction with service delivery regarding coordinated and comprehensive care was significantly influenced by the service provider and the parent/caregiver-related variables (R2=0.63 and R2=0.59, respectively). Finally, in the event of satisfaction with services in terms of respectful and supportive care, each factor accounted for a small and approximately equal amount of variance in the mean score of relevant MPOC-20 subdomain (range of adjusted R2=0.10–0.18). Conclusion: Factors or determinants identified in the current study as having the potential to increase parents’/caregivers’ satisfaction with rehabilitation services should be considered when providing rehabilitation services.Öğe Determination of functional movement screening scores in wrestlers and examination in terms of some variables(EDRA S.p.A, 2023) Ünver, Gülşah; Kocaman, HikmetThe aim of this study was to determine functional movement screening (FMS) scores in wrestlers to examine FMS scores in terms of years of sport experience and wrestling weight, and to determine the relationship between FMS score and body mass index (BMI). Materials and methods. Forty-four male wrestlers were included in this study. Functional movement analyses were performed of the wrestlers. In addition, the wrestlers filled out a personal information form which contains information such as age, years of sport experience, wrestling weight, and height. Results. The FMS scores of the wrestlers have been found to be 16.07 ± 1.87. A statistically significant difference has been found in terms of FMS scores according to years of sport experience and wrestling weight (p < 0.05). A statistically significant correlation has been found between the FMS score with BMI (p < 0.05). Conclusions. It has been concluded that the FMS scores of the wrestlers with more years of sport experience are higher, the FMS scores of the wrestlers with low body weight are lower, and the FMS score increases as the BMI increases. It is thought that the functional movement levels of the wrestlers should be evaluated regularly at certain intervals and interpreted according to their characteristics.Öğe Determination of predictors associated with pain in non-surgically treated adults with idiopathic scoliosis(Bmc, 2024) Yetiş, Mehmet; Yıldız, Nazım Tolgahan; Canlı, Mehmet; Kocaman, Hikmet; Yıldırım, Hasan; Alkan, Halil; Valamur, IremBackground It is recognized that pain related to adult individuals with idiopathic scoliosis (IS) substantially impacts individuals' daily activities and quality of life. 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 Evaluation of intracerebral ventricles volume of patients with Parkinson's disease using the atlas-based method: A methodological study(Elsevier Science Bv, 2019) Kocaman, Hikmet; Acer, Niyazi; Köseoğlu, Emel; Gültekin, Murat; Dönmez, HalilKnowing the volumetric changes in brain can allow for the estimation of the disease progression of various neurodegenerative disorders. Many studies have been shown that the volumetric changes in the some brain structures especially including the dopaminergic neurons, in patients with Parkinson's disease (PD). The objective of this study was to compare intracerebral ventricles volume in patients with PD and healthy subjects to compare an automated atlas-based method (MRIStudio software) and a manual method (ImageJ). T1-weighted brain Magnetic Resonance Imaging (MRI) data of 21 patients with PD and 20 healthy individuals were used to calculate the intracerebral ventricle volumes. Measurement results obtained by ImageJ were considered as the gold standard. We found a significant increase in the left occipital part of the lateral ventricle volume in the patients with PD compared to the control subjects (p < 0.05). Also, no significant difference was found between the two methods of measurement (p > 0.05), meaning that a substantial agreement was found between the results obtained with the atlas-based analysis and manual method. The present study showed that MRIStudio can be performed easily and accurately on routine MRI scans for which the total intracerebral ventricles volume is to be estimated in PD. We suggest that, the attained volume values of intracerebral ventricles may provide a precious data for volumetric dependences of the anatomical structures in several clinical conditions.Öğe Examination of functional ankle instability in soccer players: a prospective study(Kamuzu Univ Health Sciences - Kuhes, 2023) Ünver, Gülşah; Kocaman, Hikmet; Eroğlu, HüseyinAim The foot area is one of the most active body parts in soccer branch. There may be various loads on the foot in soccer players and ankle instability may be occur. The present study aimed to evaluate functional ankle instability in soccer players and examine it in terms of some variables. Methods A total of 175 male soccer players were included in the present study. The ankle instability of soccer players was evaluated with the Identification of Functional Ankle Instability (IdFAI) scale. Results It was determined that 35.4% of the soccer players had functional ankle instability in their right foot, 29.7% in their left foot, and 46.3% on at least one side. The average IdFAI total score of the all players was 9.39 +/- 6.18 for the right side and 8.20 +/- 5.55 for the left side. When the soccer players were evaluated regarding the position they played, it was determined that the mean of the IdFAI total score for both feet was higher in the midfielders. Conclusions It is thought that the results of the study may contribute to the determination of risk factors for the foot part and shed light on the development of prevention strategies for injuries in soccer players.Öğe 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 Factors influencing of quality of life in adolescent idiopathic scoliosis(Elsevier, 2022) Kaya, Mehmet Hanifi; Erbahçeci, Fatih; Alkan, Halil; Kocaman, Hikmet; Büyükturan, Buket; Canlı, Mehmet; Büyükturan, ÖznurBackground: Adolescent idiopathic scoliosis (AIS) is the lateral and horizontal deformity of the vertebral column which occurs idiopathically during adolescence.

The five-times sit-to-stand test (FTSST) can evaluate the muscle strength and balance of the lower extremities. This study's primary purpose was to assess the validity and reliability of the FTSST in patients who have undergone ACL-R. Material and Methods Forty-three people who had undergone ACL-R surgery were included in the study. The study's primary outcome measure, the FTSST, was assessed by two different investigators. Secondary outcome measures were body balance, quadriceps muscle strength, Tegner activity score (TAS), and Lysholm score. Results The FTSST's test-retest and inter-rater reliability were both high (ICC: 0.99). The FTSST also showed a strong statistically significant correlation with all secondary outcome measures, including balance, quadriceps muscle strength, TAS, and Lysholm score (p<0.05). Conclusions According to the study results, the FTSST is a tool-free, simple method for assessing muscle strength and the body balance level, mobility level, and functional status of the knee in patients who have undergone ACL-R surgery.Öğe An investigation into the relationships between physical activity level, burnout, job satisfaction, quality of life and sociodemographic factors in academicians(2023) Yıldız, Nazım Tolgahan; Kocaman, HikmetPurpose: The aim of the study was to examine the relationships between physical activity level (PAL), burnout, job satisfaction, quality of life, and some sociodemographic factors in academicians. Materials and Methods: The study included 214 academicians, including research assistants, lecturers, assistant professors, associate professors, and professors. Computer usage time, tenure of office, age, experience abroad, PAL (with International Physical Activity Questionnaire), burnout level (with Maslach Burnout Inventory), job satisfaction (with Job Satisfaction Scale for Academicians), and quality of life (with Short Form-36 Health Survey) were evaluated. Results: It was observed that computer usage time, PAL, burnout, job satisfaction, and quality of life varied according to the academic title (p<0.05). Computer usage time and burnout level were the highest among research assistants, while job satisfaction and quality of life were the lowest. This finding was found to be the opposite in professors (p<0.05). Strong negative relationships were observed between burnout and job satisfaction, and quality of life (p<0.05). Those with experience abroad had lower burnout levels, higher job satisfaction, and quality of life (p<0.05). In each academic title group, significant and strong negative relationships were observed between PAL and burnout, while significant strong positive relationships were observed between PAL and job satisfaction and quality of life (p<0.05). Conclusion: It is thought that the academicians' burnout levels can be decreased and job satisfaction and quality of life can be increased by improving working conditions, enabling them to gain experience abroad, and encouraging adequate and regular physical activity.Öğe Investigation of Factors Associated with Pain Level in Individuals with Chronic Non-Specific Low Back Pain(2023) Kocaman, Hikmet; Alkan, Halil; Ceylan, İsmail; Canlı, Mehmet; Kuzu, ŞafakObjectives: The aim of this study was to investigate the factors associated with pain levels in individuals with chronic non-specific low back pain (CSLBP). Material and Methods: A total of 90 patients (44 males and 46 females) diagnosed with CS LBP were included in the study. Pain level was assessed by the Visual Analogue Scale (VAS), body balance was assessed statically and dynamically by the Biodex Stability System, quadriceps femoris muscle strength was assessed by an isometric dynamometer, and disability level was assessed by the Oswestry Disability Index (ODI). A linear regression analysis was performed to determine the factors affecting pain level. Results: According to the results of linear regression analysis, static balance (anteroposterior, mediolateral, and general), dynamic balance (anteroposterior, mediolateral, and general), ODI, and quadriceps femoris muscle strength (left, right) explained 98.1% of the variance. In addition, all sub-parameters of dynamic balance (general p=0.000, anteroposterior p=0.001, mediolateral p=0.008) and ODI (p=0.000) were independent predictors of pain level. Conclusion: It was determined that pain level was associated with balance, muscle strength (quadriceps femoris), and disability level in individuals with CSBP. It was also observed that dynamic balance and ODI were factors affecting the pain level.Öğe An investigation of machine learning algorithms for prediction of lumbar disc herniation(Springer Heidelberg, 2023) Kocaman, Hikmet; Yildirim, Hasan; Goeksen, Aysenur; Arman, Gokce MerveThe prevalence of lumbar disc herniation (LDH), which makes patients' daily activities more difficult and reduces their quality of life, has tended to increase recently. Many risk factors associated with LDH have been reported. In this study, LDH was predicted using machine learning techniques using measures of the lumbar paraspinal muscles, lumbar vessels cross-sectional area (CSA), and lumbar sagittal curve. Three hundred and forty-four individuals' MR scans were prospectively enrolled (264 with LDH and 80 healthy). Predictive factors were the lumbar sagittal curve and the cross-sectional areas of the lumbar paraspinal muscles and vessels from sagittal and axial MR images. The measurements have been analyzed via ten different and most common machine learning algorithms by considering a comprehensive parameter tuning and cross-validation process. The variable importance results have been also presented. XGBoost algorithm among all algorithms has provided the best results in terms of different classification metrics including f-score ( 0.830 ), AUC ( 0.939 ), accuracy ( 0.922 ), and kappa ( 0.779 ). The findings of this study demonstrated that cross-sectional areas of the quadratus lumborum and abdominal aorta can be utilized as a reliable indicator of LDH. Consequently, the developed model and the variables found to be important may guide to healthcare professionals to make more accurate and effective decisions in terms of prediction the LDH.Öğe Investigation of sectional surface area and volume of carpal tunnel, median nerve and structures ınside in unilateral carpal tunnel syndrome(Universidad de la Frontera, 2024) Gulaçtı, Muhammet Mustafa; Acer, Niyazi; Kocaman, Hikmet; Demirel, AdnanCarpal tunnel syndrome (CTS) is a common entrapment neuropathy of the median nerve (MN). The objective of this study was to evaluate and compare the cross-sectional surface area of the canalis carpi (CC), median nerve (MN), and flexor tendons (FTs) in patients diagnosed with unilateral carpal tunnel syndrome (CTS) with those of the unaffected side, utilizing magnetic resonance imaging (MRI). Additionally, the study aimed to assess and compare the volume of the CC and MN between the affected and unaffected sides. 18 unilateral CTS female patients were included in this study. Magnetic resonance images were obtained using a 1.5-T MRI scanner. The sectional surface area and volume of the CC, MN, and structures inside were measured using Analyze version 12.0 software. The sectional surface area and volume of the CC and MN were significantly larger on the CTS side than on the healthy side (p<0.05). The results showed that the cross-sectional surface area of CC gradually decreased towards the beginning and end of the CC, but the values were higher on the side with CTS than on the healthy side (p<0.05). The cross-sectional surface area of the CC, MN, and FTs was significantly larger on the CTS side compared to the healthy side. Furthermore, the volumes of the CC and MN were notably elevated on the CTS side in comparison to the healthy side. The measurement of these parameters using MRI may be useful in the diagnosis and assessment of CTS. © 2024, Universidad de la Frontera. All rights reserved.
