- ItemDoes Pulmonary Function Testing Affect Autonomic Nervous System Activity?(GALENOS PUBL HOUSE, 2026-03) Yalçın, Gülay; Erdoğmuş Gülcan, Server; Kavlak, Erdoğan; 308202; 392815Objective: The autonomic nervous system (ANS) regulates vital functions such as heart rate (HR) and respiration. Pulmonary function tests (PFTs), which require forced breathing maneuvers, may influence ANS activity, potentially affecting the accuracy of autonomic measurements. This study aimed to investigate the effects of PFT on ANS activity and to assess the reliability of the test order. Material and methods: Forty-eight healthy university students (32 women, 16 men; mean age 19±0.92 years) participated. ANS activity was assessed by heart rate variability (HRV) analysis using the Elite HRV Corsense device. HRV was recorded at rest in a seated position (first measurement), was repeated after a 5-minute rest (second measurement), and was recorded again following PFT performed with a Medwelt SP10 spirometer (third measurement). Results: Comparison of the first and second measurements showed a statistically significant increase only in the root mean square of successive differences (RMSSD) parameter, with no significant changes in other indices. Comparison of the second and third measurements revealed no significant differences in RMSSD or average HR; however, significant changes were observed in the low-frequency (LF) and high-frequency (HF) components and in the LF/HF ratio. Conclusion: Respiratory maneuvers during PFT may temporarily alter ANS activity, particularly affecting parasympathetic-sympathetic balance. The differences between the first and second measurements emphasize the importance of adequate rest periods before HRV assessment. Measurements taken prior to PFT appear to be more reliable for the accurate evaluation of autonomic function.
- ItemCOMPARISON OF THE EFFECTS OF NERVUS VAGUS STIMULATION, TENS, AND BACKUP STIMULATION DEVICE ON THE AUTONOMIC NERVOUS SYSTEM AND PAIN IN FIBROMYALGIA PATIENTS(TÜRKİYE FİZYOTERAPİSTLER DERNEĞİ, 2025-09) Yalçın, Gülay; Kayış, Rukiye; Beceni, Esra; Külekçioğlu, Sevinç; 308202; 392833Purpose: This study aimed to compare the acute effects of vagus nerve stimulation (VNS), transcutaneous electrical nerve stimulation (TENS), and the backup stimulation device (Backup) on pain, sympathetic, and parasympathetic nervous system functions in fibromyalgia patients. Methods: Thirty fibromyalgia patients (aged 20-45) from a hospital in Bursa were randomly assigned to three groups: VNS, TENS, and Backup stimulation device. Each group received a 30-minute session once weekly for five sessions. Pain was assessed using the visual analog scale (VAS), and sympathetic and parasympathetic functions were measured with the Elite heart rate variability device. Parameters included heart rate, root mean square of successive differences, proportion of NN50 divided by total RR intervals, low-frequency/high-frequency (LF/HF) power, and LF/HF ratio. Results: No significant post-intervention changes were found in autonomic parameters across groups (p>0.05). However, all groups showed a significant reduction in VAS scores (p<0.05), indicating effective pain relief. Heart rate significantly decreased only in the Backup group (p<0.05), suggesting a shift toward parasympathetic dominance. Between-group analysis revealed significant differences in VAS scores between the TENS and VNS groups, and the VNS and Backup groups (p<0.05), indicating variability in pain response. Conclusion: TENS, VNS, and Backup stimulation devices effectively reduce pain in fibromyalgia patients. The heart rate reduction in the Backup group suggests a potential effect on autonomic regulation, which may offer a beneficial approach for managing fibromyalgia symptoms. Although autonomic parameters showed no significant changes overall, further research is needed to understand the long-term effects and clinical relevance of these treatments.
- ItemThe Effect of Physical Activity and Sleep on Quality of Life and Depression Level in 18- 25 Years Old University Students(2025-05) Kavlak, Erdoğan; Erdoğmuş Gülcan, Server; Yalçın, Gülay; 392815; 308202Aim: Physical activity,which involves movements exceeding basal energy levels, affects both physical and psychological health.This descriptive study examines the effects of physical activity and sleep on quality of life and depression in university students. Methods: A total of 141 university students aged 18-25 years were included in the study.Sociodemographic data was collected using a form.Physical activity was assessed with the International Physical Activity Questionnaire short form (IPAQ), sleep quality with the Pittsburgh Sleep Quality Index (PSQI), depression levels with the Beck Depression Inventory, and quality of life with the Quality of Life Scale (SF-36). Results: While there was no statistically significant correlation between PSQI,which was used to evaluate sleep duration and quality, and SF-36 sub-parameters Physical Function (r=-0.127;p=0.133) and Physical Role Difficulty (r= - 0.155;p=0.066);There was a weak negative statistically significant relationship between the sub-parameters of Vitality (r=-0.281*;p=0.001),Social Functioning (r=-0.278*;p=0,001),Pain (r=-0.296*;p=0.000), General Health (r=-0.290*;p=0.000). A statistically significant relationship was found between PSQI and Emotional Role Difficulty (r=-0.300*;p=0.000), Mental Health (r=-0.409*;p=0.000) sub-parameters at a moderate negative level. There was also a statistically significant moderate positive correlation between the total scores of PSQI and Beck Depression Inventory (r=0.483*;p=0.000). Conclusions: Adequate sleep and physical activity improve the quality of life and mood in university students,a critical life stage.Therefore, interventions to assess and improve physical activity levels and sleep quality are necessary. In this population, physical activity levels and sleep quality should be questioned and interventions to improve them are needed.
- ItemA Comparison of Physical Activity Level, Quality of Life, Sleep Quality and Depression Levels in Mothers of Disabled Children With and Without Musculoskeletal Pain(İstanbul Gelişim Üniversitesi, 2025-11) Yalçın, Gülay; Kayış, Rukiye; 308202Aim: This study aims to compare physical activity levels, quality of life, sleep quality, and depression levels in mothers of children with disabilities, distinguishing between those with and without musculoskeletal pain. Method: A total of 61 mothers aged 20–45 years participated in the study, including 27 mothers with musculoskeletal pain, as determined by the Visual Analog Scale (VAS), and 34 mothers without musculoskeletal pain. The physical activity levels of the mothers were assessed using the International Physical Activity Questionnaire – Short Form (IPAQ), pain status with the VAS, depression levels with the Beck Depression Inventory (BDI), sleep quality with the Pittsburgh Sleep Quality Index (PSQI), and quality of life with the Nottingham Health Profile (NHP). Results: Body mass index, NHP, PSQI, VAS and number of pregnancies were statistically significantly different between the two groups (p<0.05). There was no statistically significant difference between the two groups in the results of IPAQ, BDI, number of children, number of miscarriages, smoking, presence of care assistants, educational status and economic status (p>0.05). Conclusion: Musculoskeletal pain negatively affects the sleep quality and quality of life of mothers of children with disabilities. Depression levels and physical activity levels were high in both groups. In addition, factors such as sociocultural and number of children are also associated with musculoskeletal pain.
- ItemThe effect of interval and continuous aerobic training on exercise capacity and health-related quality of life in people with coronary artery DISEASE: A randomized controlled trial(W B SAUNDERS CO LTD, 2026-02) Yalçın, Gülay; Mutluay, Fatma; 308202Background: Aerobic exercise is a fundamental component of cardiac rehabilitation in individuals with coronary artery disease (CAD). However, the comparative effects of interval and continuous aerobic training on exercise capacity and health-related quality of life (HRQoL) remain under debate. Methods: This randomized controlled trial included 40 patients with clinically stable coronary artery disease. Participants were randomly assigned to either interval aerobic training or continuous aerobic training for six weeks. The 6-min walk test (6MWT) was used to evaluate exercise capacity, and the Short Form-36 (SF-36) questionnaire was used to assess health-related quality of life (HRQoL). All assessments were performed before and after the training program. Results: Both training groups demonstrated significant improvements in exercise capacity and HRQoL following the intervention. Interval aerobic training resulted in greater improvements in 6-min walk distance, exercise test duration, and selected SF-36 domains compared with continuous aerobic training. Conclusion: Both interval and continuous aerobic training improved exercise capacity and health-related quality of life in patients with coronary artery disease. Interval aerobic training was associated with superior improvements in submaximal exercise capacity and selected quality-of-life domains, suggesting that it may be an effective alternative within cardiac rehabilitation programs.
