RESUMO
OBJECTIVE: This study aimed to investigate the synergy between the diaphragm and pelvic floor muscles (PFM) according to different exercise positions in women with pelvic floor dysfunction. Our secondary aim was to determine the short-term effects of single-week pelvic floor muscle training (PFMT) program on diaphragmatic function. METHODS: The cross-sectional study included 64 women with pelvic floor dysfunction. The participants' diaphragm and abdominal muscle functions during voluntary PFM contraction and relaxation were assessed by surface electromyography and ultrasonography. The surface electromyography assessments were performed in supine (P1), crawling (P2) and sitting (P3) positions. A single week-PFMT was conducted on women who agreed to determine the short-term responses of the diaphragm function. The muscle functions according to exercise positions were compared with Friedman Analysis of Variance, and the short-term effects of single-week PFMT on diaphragm function was analyzed with Wilcoxon Signed-Ranks Test. RESULTS: The diaphragm activity during voluntary PFM contraction was highest in P2 before and after single-week PFMT (P < .001). Positive significant correlations were found between the activities diaphragm and abdominal muscles in different exercise positions (P < .05). After single-week PFMT, diaphragm thickness increased (P = .030) in P1, but diaphragm activity did not change in all 3 exercise positions (P > .05). CONCLUSION: The synergy between the diaphragm and PFM was greater in the crawling position in women with pelvic floor dysfunction. The abdominal muscles seemed to contribute to maintaining this synergy. Therefore, PFMT combined with diaphragmatic breathing exercises in the crawling position should be considered. In addition, single-week PFMT may positively affect diaphragm function in the short-term.

BACKGROUND: Improving pelvic floor muscle training (PFMT), balance and functional activity is recommended in the treatment of urinary incontinence (UI) in the elderly people. The aim of this study is to examine whether PFMT combined with Otago exercises is effective on symptoms, balance and functional status in elderly people with UI compared to PFMT alone. METHODS: This study is an assessor-blinded, randomized controlled trial. Participants with UI aged 65 and over living in a nursing home were randomly assigned to the intervention (IG) and control groups (CG). The intervention group attended an exercise program that included Otago exercises combined with PFMT. The control group was included in the PFMT program with different positions. The duration of exercise for both groups was 45-60 min per session three times a week for 12 weeks. UI symptoms and severity (Pelvic Floor Distress Inventory-20, bladder diary), PFM muscle function (superficial electromyography), balance (Berg Balance Scale), functional status (Senior Fitness Test) and fear of falling (Falls Efficacy Scale) were measured at baseline and after the intervention. RESULTS: The median age of the IG (n: 22) and CG (n: 21) was 73.5 and 77 years, respectively. At baseline and after the intervention within the group, a significant improvement was observed in the PTDE-20 score (IG and CG, p: 0.00) and the 2-min step test in the IG (p: 0.02) and CG (p: 0.01). A significant decrease was found in the 2.45 m get up-and-go test, PFM work average onset, and PFM rest MVC EMG values (p: 0.01, p: 0.01, p: 0.00) in the IG. The PFM rest average value decreased (p: 0.04) in the CG. CONCLUSION: The findings of this study show that combining PFMT with Otago exercises, two evidence-based interventions, is beneficial for effectively treating incontinence symptoms, balance and functional status in elderly people. Thus, a triple effect can be achieved with a single exercise training in the same treatment session and for the same duration. CLINICAL TRIAL NUMBER: Clinical trial number: NCT06331039.
RESUMO
OBJECTIVE: The aim of this study is to examine whether there is a synergistic relationship between the diaphragm and pelvic floor muscles (PFM) in pregnant women. MATERIAL AND METHODS: Our study was carried out as a cross-sectional study in primigravid pregnants in the second and third trimesters. Superficial electromyography (EMG), 2D/3D ultrasonography (USG), pulmonary function test (PFT), PERFECT, maximum expiratory pressure (MEP) and inspiratory pressure (MIP) measurements were used to evaluate pelvic floor and diaphragm muscle functions during pregnancy. Mann-Whitney U test was used to show the change in the second and third trimesters, and Spearman correlation was used to determine the relationship. RESULTS: No correlation was found between the EMG data of the PFM and diaphragm, or between the USG data of the PFM and diaphragm in all participants, in the second and third trimesters. In the third trimester of the study, diaphragmatic thickness and levator hiatal area (LHA) decreased and both diaphragm and PFM % MVC EMG parameters increased. In the third trimester, FVC, MIP, MEP decreased, and nonsignificant increase in FEV1, FEV1/FVC and peak ekspiratuar flow(PEF) were detected. A significant correlation was found between pelvic floor levator hiatal area USG and FEV1/FVC in both trimesters (r: 0,577p: 0,004). CONCLUSION: There may be a synergistic relationship between the diaphragm and PFM in pregnant women, the relationship may weaken as pregnancy progresses, and there may be no coactivation relationship between the two muscles. In order to prevent the occurrence of pelvic floor dysfunction during pregnancy and to increase the effect of rehabilitation programs, the relationship between the diaphragm and the PFM should be determined and more studies should be conducted.
