Öğe Comparison of the effects of pulmonary and cognitive telerehabilitation in severe COPD(European Respiratory Society Journals Ltd, 2023) Ataç, Amine; Pehlivan, Esra; Karaahmetoğlu, Fulya Senem; Özcan, Zeynep Betül; Çınarka, Halit; Çörtük, Mustafa; Baydili, Kürşad Nuri; Çetinkaya, Erdoğan...Öğe Exercise-induced muscle oxygenation changes in fibrosing interstitial lung diseases: a near-infrared spectroscopy study(Mattioli 1885, 2025) Pehlivan, Esra; Zeren, Melih; Özcan, Zeynep Betül; Karaahmetoğlu, Fulya Senem; Demirkol, Barış; İlhan, Umut; Ataç, Amine; Çetinkaya, ErdoğanBackground: The impact of fibrosing interstitial lung disease (F-ILD) on the oxygenation of peripheral and respiratory muscles during exercise remains poorly understood. Specifically, it's unclear whether regional blood flow influences exercise capacity in these patients, and if so, to what degree. Objectives: This study aimed to investigate changes in oxygenation and blood flow volume of the intercostal (IC) and quadriceps femoris (QF) muscles during exercise in patients with F-ILD. Methods: Muscle oxygenation (SmO2) and total haemoglobin (tHb) changes of IC and QF were measured in 36 F-ILD patients using near-infrared spectroscopy (NIRS) during six-minute walking test (6MWT). Resting, minute-by-minute change, and average data were analyzed. Results: At rest, SmO(2)was significantly higher in IC compared to QF (p<0.001). When adjusted for SmO(2)at rest, SmO(2)at the different time points during 6MWT, average SmO(2)during 6MWT, and lowest SmO2 during 6MWT did not differ between QF and IC muscles. Also, SmO(2 )did not vary significantly during 6MWT in either QF (F=2.193) or IC muscle (F=1.262). THb increased more in QF than in IC. THb of IC inversely correlated to respiratory functions and 6MWT distance. Conclusion: Peripheral and respiratory muscle oxygenation in F-ILD seems to be normal. However, blood flow volume in exercising muscle, not muscle oxygenation, may be a contributing factor to exercise intolerance. Patients with poorer respiratory function may require excessive blood flow in their respiratory muscles which in turn may limit the blood flow available for exercising peripheral muscles.Öğe Investigation of inspiratory muscle training efficiency before bronchoscopic lung volume reduction: a randomized controlled trial(Sociedad Espanola de Neumologia y Cirugia Toracica (SEPAR), 2025) Pehlivan, Esra; Çetinkaya, Erdoğan; Özcan, Zeynep Betül; Karaahmetoğlu, Fulya Senem; Çörtük, Mustafa; Ataç, Amine; Çınarka, HalitIntroduction: Pulmonary rehabilitation (PR) is recommended prior to bronchoscopic lung volume reduction (BLVR) procedures to optimize patient outcomes. However, there's a lack of clear guidance on PR content. The aim of our study is to examine the effect of adding inspiratory muscle training (IMT) to standard PR before BLVR on exercise capacity, dyspnea, fatigue level and quality of life. Methods: Sixty-four patients were randomly assigned to either the PR Group (PRGr) or the PR with IMT group (IMTGr). Both groups underwent an 8-week standard PR program, including breathing exercises, muscle strengthening, and walking. Additionally, IMTGr received IMT sessions. Outcome measures comprised six-minute walking distance (6MWD), maximal inspiratory and expiratory pressures (MIP, MEP), peripheral muscle strength, modified Medical Research Council dyspnea score, fatigue symptom scale, spirometric parameters, Saint George Quality of Life Questionnaire (SGRQ), International Physical Activity Questionnaire Short Form (IPAQ-SF), and Hospital Anxiety and Depression Scale. Results: Our study found no significant difference in exercise capacity improvement between IMTGr and PRGr. However, IMTGr showed significant improvement in MIP compared to PRGr. Both groups experienced improvements in dyspnea, fatigue, and depression scores, as well as enhancements in 6MWD, MEP, peripheral muscle strength, IPAQ-SF and SGRQ scores. Conclusion: Adding IMT to PR did not show a significant difference between groups among BLVR-eligible patients. However, improved respiratory muscle strength may have positive clinical implications. Further research is needed to explore short and long-term effects.Öğe The impact of different telerehabilitation methods on peripheral muscle strength and aerobic capacity in COPD patients: a randomized controlled trial(Multidisciplinary Digital Publishing Institute (MDPI), 2024) Ataç, Amine; Pehlivan, Esra; Karaahmetoğlu, Fulya Senem; Özcan, Zeynep Betül; Çınarka, Halit; Çörtük, Mustafa; Baydili, Kürşad Nuri; Çetinkaya, ErdoğanLung diseases have profound effects on the aging population. We aimed to hypothesize and investigate the effect of remote pulmonary telerehabilitation and motor imagery (MI) and action observation (AO) methods on the clinical status of elderly chronic obstructive pulmonary disease (COPD) patients. Twenty-six patients were randomly assigned to pulmonary telerehabilitation (PtR) or cognitive telerehabilitation (CtR) groups. The programs were carried out 3 days a week for 8 weeks. The 6-min walk test (6MWT), modified Medical Research Council dyspnea score, blood lactate level (BLL), measurement of peripheral muscle strength (PMS), and electromyography activation levels of accessory respiratory muscles were the main outcomes. There was a statistically significant improvement (p < 0.05) in both groups in the 6MWT distance and in secondary results, except for BLL. Generally, in the mean muscle activity obtained from the electromyography measurement after the program, there were statistically significant increases in the PtR group and decreases in the CtR group (p < 0.05). There was a statistically significant increase in PMS in both groups. An active muscle-strengthening program has the same benefits as applying the muscle-strengthening program to the patient as MI and AO. CtR can be a powerful alternative rehabilitation method in respiratory patients who cannot tolerate active exercise programs.
