“…In addition, this assessment technique is quick and easy to apply. These advantages are important in children, adolescents, men, and some ethnic groups, who may not benefit from assessment with digital palpation and transperineal ultrasonography into vaginal [9]. Thompson et al [5] found a significant correlation between TAUS and transperineal ultrasonography, and manual muscle testing for PFMs contraction.…”

“…The ultrasonographic transducer was placed transversely across the midline of the abdomen, immediately superior to the symphysis-pubis region. The angle of the transducer was moved toward the postero-inferior direction of the bladder until it is approximately 60 o from the vertical [9][10][11][12]. The distance of the PFMs movement was calculated at rest and during the other contractions.…”

“…Then, the participants performed PFMs contraction during the other PFMs contractions. The image was captured at the highest maximum displacement and again marked with a 'X' [9] ( Figure 1). The difference between the resting position and the other task position's at the end of the bladder base was measured by using the on-screen calipers [12].…”

Objective: Pelvic floor muscles (PFMs) form the base of the abdomino-pelvic cavity and also the PFMs function is important for urinary continence. PFMs training (PFMT) is considered to be the first method for PFM dysfunction. This study demonstrated correct PFMs contraction among commonly used different contraction methods for PFMT. Design: Cross-sectional study. Methods: In this study, nineteen middle-aged (40-70 years) women participated. To evaluate PFM function, ultrasonography was used to measure the distance of the bladder base movement. The distance of the PFM movements were calculated at rest and during the other contractions. The following four different contraction methods were performed randomly: (1) PFM contraction, (2) abdominal drawing-in maneuver (ADIM), (3) anal contraction, and (4) hip adductor muscle contraction. The participants held the contraction for 3 seconds for a total of 3 times with a 30 seconds rest period between each trial. The mean of three measurements in each position were obtained and compared with that in the resting position. Results: The bladder base movement values were significantly greater when comparing PFM with ADIM and hip adductor contractions (p<0.05). The bladder base movement values were significantly greater when comparing ADIM and anal contractions with hip adductor contractions (p<0.05). Conclusions:The results of this study suggest that performing PFM contractions is the best method among the common methods for PFMT. Performing PFM contractions was more effective than the other contraction methods.

Inter‐rater reliability and variability of ultrasound measurements of abdominal muscles and fasciae thickness

et al. 2019

Ultrasound (US) imaging is being increasingly used by Physical and RehabilitationMedicine (PRM) specialists to measure the thickness of abdominal muscles. The current study set out to assess the inter-rater reliability of US measurements of the thickness of the abdominal muscles/fasciae. Three raters (1 = orthopedic specialist, expert on fasciae; 2 = PRM resident; 3 = PRM specialist) with different levels of US training examined the abdominal muscles and fasciae of a healthy volunteer under supine resting and dynamic conditions following a standard US protocol. The probe was positioned along the right lateral abdominal wall at the height of the 12th rib: (1) above the umbilicus at the linea alba, (2) to the side of and approximately 2 cm from the umbilicus, (3) along the mammillary line, and (4) along the anterior axillary line. Each rater measured 17 anatomical structures six times during two sessions. The relative error of the measurements (intra-rater variability) was slightly higher for the fasciae than for the muscles, and during the dynamic condition than the resting condition. Inter-rater reliability was good under both conditions for the fasciae (Intraclass Correlation Coefficient = ICC = 0.83) and excellent for the muscles (ICC = 0.99). Knowledge of the fascial anatomy of the abdominal wall is essential for accurate ultrasound examinations and for improving reliability. These findings confirm that US imaging is a reliable, non-invasive, cost-effective instrument for evaluating the abdominal muscles/ fasciae. Clin. Anat. 32:948-960, 2019.

Background and Objective: It has been suggested that pelvic floor dysfunction may contribute to the development of lumbopelvic pain as a result of changes in trunk muscle control. However, there is limited evidence that pelvic floor muscle training (PFMT) can improve clinical outcomes in women with lumbopelvic pain. Databases and Data Treatment: Six databases were searched for randomized controlled trials (RCTs) comparing the effectiveness of PFMT to other conservative interventions (usual physiotherapy care or minimal intervention), no treatment or placebo interventions on pain and disability in women with lumbopelvic pain. Results: We included eight RCTs totalling 469 participants. PFMT was more effective than minimal intervention for lumbopelvic pain [mean difference (MD) 15.9/100 (95% confidential interval (CI), 8.2 to 23.6; p = 0.00; I 2 = 3.92%)] and disability [standardized mean difference (SMD) 0.5 (95% CI 0.1-0.9; p = 0.00; I 2 = 0%)] during pregnancy. PFMT was more effective than usual physiotherapy care for pain (MD 11.7/100 [95% CI 7.5-15.9; p = 0.00; I 2 = 94.14%]) and disability (SMD 0.3 (95% CI 0.0-0.6; p = 0.01; I 2 = 82.54%]) in non-pregnant women. Effect sizes were in general of arguable clinical relevance. Conclusions: Overall, the certainty of the evidence was very low to low. There is no conclusive evidence that the addition of PFMT to usual physiotherapy care or minimal intervention is superior to minimal intervention and usual care alone given the small number of studies and high levels of heterogeneity of included studies. Further well-designed trials are needed to establish the effectiveness of PFMT for lumbopelvic pain in women.
