Effect of Pelvic Floor Muscle Training Using Pressure Biofeedback on Pelvic Floor Muscle Contraction and Trunk Muscle Activity in Sitting in Healthy Women

Abstract

Pelvic floor muscle training (PFMT) has been recommended as the first choice as one of the effective methods for preventing and improving urinary incontinence (UI). We aimed to determine whether pressure biofeedback unit training (PBUT) improves short term and retention performance of pelvic floor muscle contraction. The muscle activities of the external oblique (EO), transversus/internal oblique (TrA/IO), multifidus (MF) and the bladder base displacement were measured in the verbal feedback group (n = 10) and PBU group (n = 10) three times (baseline, post-training, and at the 1-week follow-up). Surface electromyographic activity was recorded from the EO, TrA/IO, and MF muscles. The bladder base displacement was measured using ultrasound. The results were analyzed using two way mixed ANOVA. The bladder base displacement may have elevated more in the PBU group than in the verbal feedback group due to decreased TrA/IO activity. These findings indicate that PBUT is a better method than verbal feedback training.

Relationship between Female Sexual Dysfunction and Trunk Stability Post-Stroke: A Cross-Sectional Study

“…While variables such as depressive symptoms and urinary incontinence did not exhibit significant differences between groups, others such as SD, QL, and TS showed notable distinctions. This underscores the multifactorial nature of post-stroke sexual function, emphasizing the importance of considering various factors in its assessment and management [25,26] [16] reported that the activation of PF muscles in a sitting position creates an inconsistent pattern of activation response in trunk muscles, concluding that they may be more involved in maintaining a position against gravity than in acting as coactivators of PF muscles [29]. A possible reason for the discrepancy in this last study's results could be the difference in the assessment position, as trunk and PF muscles can plausibly change their coactivation pattern depending on postural demands [30].…”

“…Stroke severity was recorded by the National Institute of Health Stroke Score (NIHSS), which classifies severity into no stroke symptoms (0), minor (1-4), moderate (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), moderate to severe (16)(17)(18)(19)(20), and severe . The dependency level was assessed with the Barthel Index (BI).…”

“…Urinary incontinence (UI) poses significant challenges to women's quality of life and health, leading to mental-social disorders such as depression, reduced self-confidence, and limitations in daily activities [16]. The intricate interplay between pelvic floor muscles and trunk stability is increasingly recognized in the realm of rehabilitation.…”

“…Pelvic floor muscles function in tandem with the abdominal wall, diaphragm, deep trunk muscles, and lumbar musculature to facilitate visceral support, urinary and fecal continence, and maintain postural stability against gravitational forces [17][18][19]. In addition, pelvic floor muscles seem to be closely related to abdominal wall muscles, such as the diaphragm, deep muscles of the trunk, and lumbar area, acting as a synergic unit for sensory-motor function and stability [16,20]. Consequently, any dysfunction within the pelvic floor musculature has the potential to disrupt the integrity of the abdominal-pelvic-lumbar muscular complex, thereby compromising trunk stability, and vice versa.…”
