    Effect of Inspiratory Muscle Training on Diaphragm Function and Activity Performance in Subacute Ischemic Stroke Patients: A Single-Blind Randomized-Controlled Trial
    (SAGE Publications Inc., 2026) Akçay S.; Akyol D.K.; Erkut Ü.; Karagözoğlu Coşkunsu D.; Kunduracilar Z.; Bajrami A.; Dinç Yavaş A.; Kunduracilar, Zuhal; Coskunsu, Dilber Karagozoglu; Bajrami, Arsida; Akçay, Sümeyye; Akyol, Dudu Kübra; Erkut, Ümit; Karagözoğlu Coşkunsu, Dilber; Yavas, Arzu Dinc; Dinç Yavaş, Arzu
    Background: Respiratory dysfunction is common after stroke and may negatively affect functional recovery. Inspiratory muscle training (IMT) has been proposed to enhance diaphragmatic function and activity performance in this population. Objective: To investigate the effects of IMT on diaphragm function and activity performance in patients with subacute ischemic stroke. Methods: In this randomized controlled, single-blind trial, 26 patients with subacute ischemic stroke (>1 month post-onset) were randomly allocated to an intervention group (IG, n = 13) or control group (CG, n = 13). Both groups received standard neurorehabilitation, aerobic training, and the Active Cycle of Breathing Technique (ACBT). The IG additionally underwent IMT, 5 days per week for 6 weeks (30 sessions). Assessments included maximal inspiratory and expiratory pressures (MIP, MEP), diaphragmatic thickness (Ti, Te) and excursion via ultrasonography, 6-minute walk test (6MWT), and Canadian Occupational Performance Measure (COPM). Results: Twenty-two participants completed the study (IG = 11; CG = 11). Significant within-group improvements were observed in both groups for MIP, MEP, Ti, TF, excursion, 6MWT, and COPM scores (P < .05). Between-group analyses showed significantly greater improvements in the IG for ΔMIP (P < .001), ΔMEP (P = .003), affected-side ΔTi (P = .007), ΔTF (P = .008), and Δexcursion (P = .005). No significant differences were found for 6MWT and COPM (P > .05). Conclusions: IMT effectively improves respiratory muscle strength, diaphragmatic thickness, and excursion in subacute ischemic stroke and may be a valuable addition to post-stroke rehabilitation programs.

    Ultrasound Measurements of Pelvic Floor and Diaphragm Muscles in Chronic Obstructive Pulmonary Disease Patients With Urinary Incontinence
    (Springer London Ltd, 2025) Balaban, Mehtap; Dusgun, Elif Sena; Nur, Hifziye Pervin; Lalecan, Nida; Sertcelik, Umran Ozden; Celenay, Seyda Toprak; Ozden Sertcelik, Umran; Toprak Celenay, Seyda
    BackgroundThe precise manner in which morphological properties of pelvic floor muscles (PFMs) and diaphragm muscle in Chronic Obstructive Pulmonary Disease (COPD) patients with Urinary Incontinence (UI) are affected remains unclear.AimThis study aimed to compare the ultrasound measurements of PFMs and diaphragm muscle in COPD patients with and without UI.MethodsThirty COPD patients with UI [UI group, age: 61.00 (42.00-70.00) years, body mass index: 27.86 (20.20-54.69) kg/m2] and thirty COPD patients without UI [N-UI group, age: 64.00 (47.00-70.00) years, body mass index: 27.11 (20.30-35.94) kg/m2] were included. The PFMs contaction assessment and diaphragm muscle morphological properties were evaluated using the Logiq S7/Expert ultrasound device. The percentage of change in thickness of diaphragm muscle, known as the diaphragm thickening fraction index (DTFI), was also calculated.ResultsIt was found that the PFMs contraction (p = 0.018) and DTFI (p = 0.016) values were significantly lower in the UI group compared to the N-UI group. No significant differences were observed in the diaphragm thickness score during the inspiration (p = 0.973) and expiration (p = 0.233) between the groups.ConclusionsPatients with COPD and UI exhibited diminished the PFMs contaction severity and DTFI compared to those with COPD but no UI. It should be considered that UI comorbidity in COPD may negatively affect PFMs contaction severity and diaphragm muscle morphological properties.

    The Effects of Diaphragmatic Breathing Exercises on Individuals with Premature Ejaculation: A Randomized Controlled Trial
    (Oxford University Press, 2025) Erkut, Umit; Karagözoğlu Coşkunsu, Dilber; Erkut, Kubra; Özden, Ali Veysel; Coskunsu, Dilber Karagozoglu
    Background There are no standardized, evidence-based rehabilitation protocols for premature ejaculation (PE) which hinders effective management, the development of validated patient-reported outcomes, regulatory oversight, and the potential benefits of targeted interventions. Aim To investigate the effect of diaphragmatic breathing exercises (DBE) on PE. Methods Sixty-two participants with PE were randomly assigned to Group I (n = 31) or Group II (n = 31). Both groups received behavioral therapy (BT) and pelvic floor muscle training (PFMT) twice daily, three days a week, for eight weeks. Additionally, Group I recieved DBE twice daily, every day, for eight weeks. Intravaginal ejaculation latency time (IELT) was calculated with a stopwatch, at the end of the 8th week (post-treatment), and at 1-year follow-up. Pelvic floor muscle (PFM) strength and endurance were evaluated with ultrasound, and changes in the in the autonomic nerves system (ANS) parameters (including the root mean square of successive differences [RMSSD], proportion of NN50 [PNN50], low-frequency [LF] power, and high-frequency [HF] power) were evaluated with an Elite HRV device at pre-treatment and post-treatment by a blinded assessor. Outcomes Primary outcome measurements were IELT, PFM strength and endurance, and changes in ANS paramaters. Results The study was completed by 29 participants (mean age = 31.4 ± 6.5 years) in Group I and 30 (mean age = 31.3 ± 7.6 years) in Group II. At post-treatment, all outcome measures showed significant improvements in both groups (P <.001 for all). Compared to Gropu II, Group I showed significantly greater improvements in IELT(P=0.12), RMSDD (P<.001), PNN50 (P=.003), LF Power (P<.001), HF Power (P=.003), strength(P<.001), and endurance (P<.001). The median IELT increase from baseline to post-treatment was 283 seconds (range: 84-870; 900%) in Group I and 204 seconds (range: 44- 581; 690%) in Group II. While IELT declined significantly from post-treatment to 1-year follow-up in Group II, no statistically significant change was found in Group I. Clinical Implications The effect of DBE on the ANS may help regulate the ejaculatory reflex. Strengths and Limitations This is the first study to apply breathing exercises with BT and PFMT in men with PE. Limitations include the lack of exercise adherence records beyond 8 weeks and the estimation-based IELT measurement at baseline. Conclusion Adding DBE, to BT and PFMT, yields better results in IELT (at 8 weeks and 1 year) and inreases PFM strength and endurance of PFM (at 8 weeks) in men with PE. © 2025 Elsevier B.V., All rights reserved.
