Article Citation - WoS: 3The Effects of Respiratory Muscle Functions on Trunk Muscle Endurance in Healthy Young Adults(Dokuz Eylul Univ Inst Health Sciences, 2023-05-31) Aktan, Özge Ocaker; Aktan, Rıdvan; Yakut, Hazal; Yakut, Hazal; Ozalevli, Sevgi; Kara, Bilge; Ocaker Aktan, OzgePurpose: Respiratory muscles play a dual role in breathing and trunk stability during activities. The relationship between respiratory muscle functions and trunk stability has not yet been clarified. The aim of the study was to examine the effects of respiratory muscle functions on trunk muscle endurance in healthy young adults. Methods: McGill's trunk muscle endurance tests, which consist of trunk flexion endurance test (FE), Sorensen test (ST) and Side Bridge test (SB), were used to evaluate the participants' trunk muscle endurance. Respiratory muscle strength was evaluated by measuring intraoral maximal inspiratory and expiratory pressures using an intraoral pressure meter device. The respiratory muscle endurance test was performed with the incremental threshold load protocol using a threshold IMT device. Results: A total of 51 healthy young adults, with a mean age of 21.8 ± 3.2 years, were evaluated. The results of the linear regression models were significantly explained 46% of the variance in the SB and 38% in the FE, (for SB Adj R2=0.46, F=21.40, p< 0.001 and for FE Adj R2=0.38, F=15.65, p< 0.001). Respiratory muscle endurance contributed 30% to the endurance of the trunk flexor muscles, while respiratory muscle strength contributed only 8%. Similarly, respiratory muscle endurance contributed 38% to the endurance of the trunk lateral flexor muscles, while respiratory muscle strength contributed only 8%. Conclusion: Although respiratory muscle strength and respiratory muscle endurance were independent contributors to trunk muscle endurance, respiratory muscle endurance more affected trunk muscle endurance than respiratory muscle strength in healthy young adults.Article Citation - WoS: 2Validation of the Rapid Assessment of Physical Activity Questionnaire in Older Patients With Chronic Obstructive Pulmonary Disease(Dokuz Eylul Univ Inst Health Sciences, 2021-09-20) Aktan, Ridvan; Ozalevli, Sevgi; Yalcinkaya, Gamze; Alpaydin, Aylin Ozgen; Sevinc, CanPurpose: There are not many questionnaires that have proven validity and reliability in evaluating the level of physical activity in older patients with chronic obstructive pulmonary disease (COPD). In clinical and scientific studies, it is important to quickly determine the physical activity level of patients in terms of time management. The aim of the study was to examine the validity of the rapid assessment of physical activity (RAPA) questionnaire in older patients with COPD. Methods: A total of 105 older patients with COPD surveyed the short form of the International Physical Activity Questionnaire (IPAQ-SF) and after 2 weeks RAPA questionnaire as well. The IPAQ-SF was accepted as the gold standard for physical activity assessment in COPD. Furthermore, patients were assessed for a 6-min walking test (6MWT) and perceived dyspnea (with modified medical research dyspnea scale (mMRC)). Correlation coefficients (r) was used for the relationship between RAPA and IPAQ-SF. Results: There were significant positive correlations between RAPA and IPAQ-SF total score (r = 0.968, p<0.001), 6MWT (r = 0.626, p<0.001), in addition to significant negative correlation between the RAPA and mMRC scores (r = -0.454, p<0.001). The RAPA showed good sensitivity (87.5%) and a specificity (100%) value. Positive and negative predictive values of the RAPA were 100% and 96.4% respectively. Conclusion: This study showed the RAPA was an easy-to-use, valid, and reliable questionnaire to measure physical activity levels in older patients with COPD.
