Are clinically recommended pelvic floor muscle relaxation positions really efficient for muscle relaxation?

Does pelvic floor and abdominal muscle function and the synergy between these muscles change in young and older women with urinary incontinence?

AIM

The aim of this study was to examine the synergistic relationship between the pelvic floor muscles (PFM) and abdominal muscles in older women with urinary incontinence (UI). Our secondary aim is to compare PFM and abdominal muscle functions and synergistic relationship according to incontinence type in younger and older women.

MATERIAL AND METHODS

This cross-sectional study was conducted with 46 older and 31 younger women. Urogenital Distress Inventory (UDI-6) and Over Active Bladder-Validated 8 (OAB-V8) were used to evaluate the severity of participants' urinary symptoms, and the Incontinence Impact Questionnaire (IIQ-7) was used to evaluate the quality of life related to the symptoms. PFM function was evaluated by superficial electromyography (EMG) and digital palpation; abdominal muscle function was evaluated by EMG.

RESULTS

The average ages of the participants in the younger and old female groups were 49.74 ± 7.25 years and 74.87 ± 5.41 years, respectively. PFM endurance (p = 0.005), number of fast repetitions (p = 0.073) and work average value of the participants in the older women group were found to be lower than those in the younger women group (p = 0.002). In the group of older women with mixed incontinence (MUI), PFM endurance (p = 0.022), PFM (p = 0.002), Transversus abdominis (TrA) (p = 0.007), rectus abdominis (RA) (p = 0.015), internal oblique (IO)(p = 0.002) and external oblique (EO) abdominal muscles (p = 0.001) work average values ​​were significantly lower. In the younger women group with urge incontinence (UUI), the PFM work average value was higher than in the older women group (p = 0.021). During PFM contraction, a moderate positive correlation was found between PFM and RA (r = 0.498, p = 0.001), IO (r = 0.405, p = 0.006) and EO (r = 0.442, p = 0.002) in the older women group.

CONCLUSION

This study showed that older women with UI demonstrated reduced PFM endurance, fewer fast PFM contractions, and lower PFM and abdominal muscle activity compared to younger women with UI. A positive association was observed between the PFM and the RA, IO, and EO muscles specifically in older women with UI. Importantly, our findings indicate that both PFM and abdominal muscle function decline with age in women, irrespective of UI status, leading to a worsening of related symptoms. Consequently, we recommend the implementation of preventive physiotherapy and rehabilitation programs beginning at a young age to preserve and optimize PFM and abdominal muscle function in women.

Are pelvic floor muscle function, quadriceps femoris muscle, gluteus medius muscle, hand grip strength and functional performance affected by incontinence types in elderly people with urinary incontinence?

AIM

The aim of this study is to examine the relationship between incontinence type and pelvic floor muscle function, gluteus medius muscle, quadriceps femoris muscle, hand grip strength, functional performance and balance in elderly people with incontinence.

MATERIALS AND METHODS

This cross-sectional study was conducted in a nursing home with 78 elderly people with stress (SUI, n: 20), urgency (UUI, n: 27) and mixed (MUI, n: 31) urinary incontinence. "Urogenital Distress Inventory-6, Incontinence Impact Questionnaire Form-7, Overactive Bladder-8" were used to evaluate incontinence symptoms and severity. Superficial electromyography was used to evaluate the function of the PFM. A hand dynamometer was used to evaluate hand grip strength, and a digital manual muscle tester was used to evaluate quadriceps femoris (QF) and gluteus medius muscle strength. Short Physical Performance Battery and Time Up and Go Test were performed for functional performance.

RESULTS

There was no significant difference between PFM contraction and relaxation functions, gluteus medius, QF muscle strength, functional performance (p > 0.05) but hand grip strength was highest in the group with UUI (ptotal: 0.022). The group with the highest rate of low hand grip strength is MUI (38.7%). A weak positive correlation was found between QF muscle strength and PFM Work Average value in the MUI group (r: 0.370, p: 0.048). In the MUI group, a moderate positive correlation was found between hand grip strength and gluteus medius muscle strength (r: 0.499, p: 0.005).

CONCLUSION

Our findings show that hand grip strength is related to the type of incontinence in the elderly people. The average hand grip strength was highest in the elderly people with UUI. Additionally, there was a positive relationship between gluteus medius and hang grip strength in MUI. It may provide guidance for evaluation and risk factors in elderly people with incontinence.

Effectiveness of exercise interventions on urinary incontinence and pelvic organ prolapse in pregnant and postpartum women: umbrella review and clinical guideline development

INTRODUCTION AND AIMS

Dysfunction related to pelvic floor muscles (PFM) is common among pregnant and postpartum women and can cause symptoms such as urinary incontinence or pelvic organ prolapse (POP). As part of developing a nationwide clinical practice guideline for nursing in Finland, the aim of this umbrella review is to summarize the existing evidence about the effectiveness of exercise interventions on urinary incontinence and POP in pregnant and postpartum women. To promote knowledge translation, recommendations for health care professionals are presented.

METHODS

We conducted an umbrella review to summarize the existing evidence. The JBI methodology for umbrella reviews was used to guide the review. The level of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, and recommendations based on the evidence were formulated by a clinical guideline working group.

RESULTS

Altogether, 9 systematic reviews, reporting findings from 89 original studies, were included. The methodological quality of the reviews was evaluated using JBI's checklist. The highest level of evidence was found for preventing the symptoms of postpartum urinary incontinence through exercise and pelvic floor muscle training (PFMT) during pregnancy. Moderate-level evidence showed that exercise and PFMT are likely to reduce the symptoms and severity of urinary incontinence, but the level of evidence was low on PFMT reducing the symptoms of POP.

CONCLUSION

We recommend encouraging and guiding pregnant and postpartum women to exercise and train PFM. We also recommend identifying pregnant and postpartum women with symptoms of PFM dysfunction and directing them to a physiotherapist or other health care professional specializing in pelvic floor function.

Can pelvic floor muscle training positions be selected according to the functional status of pelvic floor muscles?

Background

Pelvic floor muscle (PFM) training varies according to the functional status of PFM. It is used to strengthen underactive PFM and relax overactive PFM.

Aim

This study aimed to determine the appropriate PFM training positions according to the functional status of the PFM in women with pelvic floor dysfunction.

Materials and Methods

Seventy-six women diagnosed with pelvic floor dysfunction were included. After the digital palpation, participants were divided into four groups according to the functional status of PFM: normal, overactive, underactive, and nonfunctional. Participants' PFM and abdominal muscle functions were assessed with superficial electromyography in three positions (modified butterfly pose-P1, modified child pose-P2, and modified deep squat with block pose-P3). Friedman's analysis of variance and the Kruskal-Wallis test were used to assess whether the function of the muscles differed according to the functional status of the PFM and training positions.

Results

Normal PFM maximally contracted and relaxed in P1, whereas nonfunctional PFM was in P3 (P > 0.05). Overactive and underactive PFM was most contracted in P2 (P > 0.05) and relaxed in P1 (P < 0.001). In each functional state of the PFM, all abdominal muscles were most relaxed in P1, while their most contracted positions varied (P < 0.05).

Conclusion

This study showed that the positions in which the PFM relaxes and contracts the most may vary according to the functional status of the PFM. Therefore, different PFM training positions may be preferred according to the functional status of the PFM in women with pelvic floor dysfunction. However, more study needs to be done in this subject.

Exercise Position to Improve Synergy Between the Diaphragm and Pelvic Floor Muscles in Women With Pelvic Floor Dysfunction: A Cross Sectional Study

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.
