Introduction and hypothesis
The objectives of this study were to investigate the level of pelvic floor muscle (PFM) function in women with pelvic floor dysfunction (PFD) referred by gynaecologists and urologists for in-hospital pelvic floor muscle training (PFMT), and to identity associated factors for a low level of PFM function.Methods
Data of women with PFD referred to a PFMT programme were included in a retrospective chart review. Measurement of PFM function performed by digital vaginal palpation included: voluntary PFM contraction, PFM strength (Modified Oxford Grading Scale) and PFM static endurance.Results
Data of 998 women, mean age 56 (SD 13) years, with PFD (urinary incontinence, n?=?757, anal incontinence, n?=?36, pelvic organ prolapse, n?=?111, other PFD, n?=?94) were analysed. In all, 690 women (70 %) were, at baseline, unable to perform correct voluntary PFM contraction, mean PFM strength was 1.5 (SD 1.0) points, mean PFM static endurance was 16.7 (SD 16.1) seconds. Age ≥ 65 years and year of referral > 2000 were significantly (p?< 0.01) associated with the ability to perform correct PFM contraction. Likewise, year of referral was significantly associated with high PFM strength (p?< 0.01).Conclusions
The majority of the women were unable to perform correct voluntary PFM contraction and almost all had low PFM strength. The most important factor associated with a low level of PFM function was age. 相似文献2.

Introduction and hypothesis This observational study was undertaken to determine knowledge, prior instruction, frequency of performance, and ability to
perform pelvic floor muscle exercises in a group of women presenting for evaluation of pelvic floor disorders.
Methods Three hundred twenty-five women presenting for evaluation of pelvic floor disorders were questioned concerning knowledge and
performance of pelvic floor muscle exercises (PMEs) and then examined to determine pelvic floor muscle contraction strength.
Results The majority of women (73%) had heard of PMEs, but only 42% had been instructed to perform them and 62.5% stated they received
verbal instruction only. Only 23.4% of patients could perform pelvic muscle contractions with Oxford Scale 3, 4, or 5 strengths.
Increased age, parity, and stage of prolapse were associated with lower Oxford scores.
Conclusions Although most women with pelvic floor disorders are familiar with PMEs, less than one fourth could perform adequate contractions
at the time of initial evaluation. 相似文献

Transabdominal ultrasound measurement of pelvic floor muscle activity when activated directly or via a transversus abdominis muscle contraction 总被引:3,自引:0,他引:3
AIMS: The purpose of the present study was to compare the effectiveness of instruction to contract the pelvic floor muscles (PFM), the transversus abdominis (TrA), and the TrA + PFM visualized as displacement of the pelvic floor by ultrasound. MATERIALS AND METHODS: Twenty female physical therapists, mean age 41.1 years (range 26-56) participated in the study. A 3.5 MHz 35 mm curved linear array ultrasound transducer (Dornier Medtech) was placed in the mid-sagittal plane immediately suprapubically, angled at 15-30 degrees from the vertical depending on subcutaneous fat and anatomical variations, to image the pelvic floor. Six trials of three maneuvers in random order were performed: contraction of PFM, TrA, and TrA + PFM. RESULTS: In spite of correct contractions assessed by palpation and clinical observation, one subject demonstrated a downward movement of the pelvic floor during PFM contraction on ultrasound. Six subjects (30%) showed a downward movement during a TrA- contraction, and two during the combined TrA + PFM contraction. Instruction to contract PFM produced significantly greater mean displacement: 11.2 mm (95% CI 7.2-15.3) than TrA 4.3 mm (95% CI -0.2-8.8), P < 0.01, and combination: 8.5 mm (95% CI 5.2-12), P = 0.04. Hence, instruction of PFM contraction produced a 61.6% greater displacement of the pelvic floor in the correct direction than a TrA contraction. CONCLUSIONS: It is concluded that ultrasound is a more valid method than palpation and clinical observation to assess PFM function, and that instruction to contract the PFM produces a significantly more effective pelvic floor muscle contraction than instruction to perform a TrA contraction. 相似文献

Transperineal (TP) and transabdominal (TA) ultrasounds were used to assess bladder neck (TP) and bladder base (TA) movement
during voluntary pelvic floor muscle (PFM) contraction and functional tasks. A sonographer assessed 60 asymptomatic (30 nulliparous,
30 parous) and 60 incontinent (30 stress, 30 urge) women with a mean age of 43 (SD = 7) years, BMI of 24 (SD = 4) kg m2 and a median parity of 2 (range, 0–5), using both ultrasound methods. The mean of three measurements for bladder neck and
bladder base (sagittal view) movement for each task was assessed for differences between the groups. There were no differences
in bladder neck (p = 0.096) or bladder base (p = 0.112) movement between the four groups during voluntary PFM contraction but significant differences in bladder neck (p < 0.004) and a trend towards differences in bladder base (p = 0.068) movement during Valsalva and abdominal curl manoeuvre. During PFM contraction, there was a strong trend for the
continent women to have greater bladder neck elevation (p = 0.051), but no difference in bladder base movement (p = 0.300), when compared to the incontinent women. The incontinent women demonstrated increased bladder neck descent during
Valsalva and abdominal curl (p < 0.001) and bladder base descent during Valsalva (p = 0.021). The differences between the groups were more marked during functional activities, suggesting that comprehensive
assessment of the PFM should include functional activities as well as voluntary PFM contractions. TP ultrasound was more reliable
and takes measures from a bony landmark when compared to TA ultrasound, which lacks a reference point for measurements. TA
ultrasound is less suitable for PFM measures during functional manoeuvres and comparisons between subjects. Few subjects were
overweight so the results may not be valid in an obese population. 相似文献

The aim of the study was to evaluate whether four different techniques were able to correctly measure pelvic floor muscle
strength only. Sixteen volunteers performed a set of muscle contractions using the pelvic floor muscles (PFM) only, the abdominal
muscles with and without PFM, gluteal muscles with and without PFM, adductor muscles with and without PFM and Valsalva maneuver
with and without PFM. Pelvic floor muscle strength was evaluated by digital palpation, intravaginal EMG, pressure perineometry
and perineal ultrasound. A “non-pelvic muscle induced” reading was defined as a significant increase even though the pelvic
floor muscles were not contracted. Results were as follows: isolated abdominal muscle contraction: non-pelvic muscle induced
readings in 3/8 women with EMG and in 3/8 with pressure perineometry; isolated gluteal muscle contraction: non-pelvic muscle
induced readings in 1/2 women with EMG perineometry; isolated adductor muscle contraction: non-pelvic muscle induced readings
in 6/11 women with EMG perineometry and in 2/11 women with pressure perineometry; Valsalva maneuver: non-pelvic muscle induced
readings in 4/9 women with EMG perineometry and 9/9 women with pressure perineometry. It was concluded that EMG and pressure
perineometry do not selectively depict pelvic floor muscle activity. 相似文献

Introduction and hypothesis
We compared the maximal voluntary contraction (MVC) and strength of pelvic floor muscles (PFM) of pregnant and nonpregnant women using surface electromyography (SEMG).Methods
Fifteen pregnant primiparous women and 15 nulliparous nonpregnant women were evaluated. The healthy pregnant women were in the third trimester of pregnancy with a single fetus and did not have any neuromuscular alterations. The nonpregnant women did not present with PF dysfunctions and, as with the pregnant women, did not have any previous gynecological surgeries or degenerative neuromuscular alterations. The evaluation methods used were digital palpation (Oxford Grading Scale, which ranges from 0 to 5) and SEMG. In the EMG exam, MVC activity was evaluated, and the better of two contractions was chosen. Before the evaluation, all women received information about PFM localization and function and how to correctly contract PFM.Results
In the EMG evaluation, MVC was significantly greater in the nonpregnant group (90.7 μv) than in the pregnant group (30 μv), with p?0.001. The same results were observed after vaginal palpation, measured by the Oxford scale, which presented an average of 2.1 in the pregnant group and 4.5 in the nonpregnant group (p?=?0.005).Conclusion
In comparison to nulliparous women, pregnant women demonstrated worse PFM function with decreased strength and electrical activity. 相似文献7.

Aims
The purposes of this study were: (i) to evaluate the reliability of vaginal palpation, vaginal manometry, vaginal dynamometry; and surface (transperineal) electromyography (sEMG), when evaluating pelvic floor muscle (PFM) strength and/or activation; and (ii) to determine the associations among PFM strength measured using these assessments.Methods
One hundred and fifty women with pelvic floor disorders participated on one occasion, and 20 women returned for the same investigations by two different raters on 3 different days. At each session, PFM strength was assessed using palpation (both the modified Oxford Grading Scale and the Levator ani testing), manometry, and dynamometry; and PFM activation was assessed using sEMG.Results
The interrater reliability of manometry, dynamometry, and sEMG (both root‐mean‐square [RMS] and integral average) was high (Lin's Concordance Correlation Coefficient [CCC] = 0.95, 0.93, 0.91, 0.86, respectively), whereas the interrater reliability of both palpation grading scales was low (Cohen's Kappa [k] = 0.27‐0.38). The intrarater reliability of manometry (CCC = 0.96), and dynamometry (CCC = 0.96) were high, whereas intrarater reliability of both palpation scales (k = 0.78 for both), and of sEMG (CCC = 0.79 vs 0.80 for RMS vs integral average) was moderate. The Bland‐Altman plot showed good inter and intrarater agreement, with little random variability for all instruments. The correlations among palpation, manometry, and dynamometry were moderate (coefficient of determination [r2] ranged from 0.52 to 0.75), however, transperineal sEMG amplitude was only weakly correlated with all measures of strength (r2 = 0.23‐0.30).Conclusions
Manometry and dynamometry are more reliable tools than vaginal palpation for the assessment of PFM strength in women with pelvic floor disorders, especially when different raters are involved. The different PFM strength measures used clinically are moderately correlated; whereas, PFM activation recorded using transperineal sEMG is only weakly correlated with PFM strength. Results from perineal sEMG should not be interpreted in the context of reporting PFM strength. 相似文献8.

A new theory claims that the pelvic floor muscles (PFM) can be trained via the transversus abdominis (TrA). The aim of the
present study was to compare the effect of instruction of PFM and TrA contraction on constriction of the levator hiatus, using
4D perineal ultrasonography. Thirteen women with pelvic organ prolapse participated in the study. Perineal ultrasound in standing
position was used to assess constriction of the levator hiatus. Analyses were conducted off-line with measurements in the
axial plane of minimal hiatal dimensions. The reduction of all the hiatal dimensions was significantly greater during PFM
than TrA contraction. All patients had a reduction of the levator hiatus area during PFM contraction (mean reduction 24.0%;
range 6.1–49.2%). In two patients, there was an increase of the levator hiatus area during TrA contraction. Instruction of
PFM contraction is more effective than TrA contraction.

Aims
The aim of this study was to evaluate the effectiveness of a Pilates exercise program with pelvic floor muscle (PFM) contraction compared to a conventional intervention in pregnant women.Methods
Fifty primiparous women, without gestational alterations, were randomized to the Pilates group (n = 25) and control group (n = 25). Interventions for both groups consisted of twice‐weekly sessions of 1 h each during the period between the 14‐16th and 32‐34th gestational weeks. The Pilates group performed a Pilates exercises program with the addition of voluntary PFM contraction. Mat‐based Pilates exercises were performed involving movement of the upper limbs, lower limbs and trunk in all sessions. The Control group walked for 10 min and performed strengthening exercises of the lower limbs, upper limbs, and trunk with resistance from an elastic band and body weight. Each woman was evaluated by an unblinded physiotherapist before and after intervention for primary (PFM strength using a manometer) and secondary (PFM strength using Oxford Scale, endurance and repeatability) outcomes. Covariance analysis (ANCOVA) was used to compare the groups using the baseline values as a covariate.Results
Thirty‐six women were included in the analysis. There were no differences between the groups for manometry. An increase in the PFM strength, endurance, and repeatability was only observed in the Pilates group. In addition, the Pilates group showed greater adherence to the intervention.Conclusion
Pilates exercise program with PFM contraction is not able to change the PFM strength assessed by manometer in pregnant women, but it improved adherence to the intervention. 相似文献10.
AIMS: To investigate the muscle activation patterns of the abdomino-pelvic region used by incontinent women during a pelvic floor muscle (PFM) contraction and a Valsalva manouevre compared to healthy, asymptomatic subjects. METHODS: Thirteen incontinent (symptomatic) women, identified using ultrasound to be consistently depressing the bladder base during PFM contraction, and thirteen continent women (asymptomatic) able to perform an elevating PFM contraction were assessed using surface electromyography (EMG) of the PFM, abdominal and chest wall muscles and vaginal and intra-abdominal pressure (IAP) measurements during PFM contraction and Valsalva under ultrasound surveillance. RESULTS: There were no differences between groups in age, parity or BMI. There was a difference in muscle activation patterns between groups (P = 0.001). During PFM contraction the PFM were less active and the abdominal and chest wall muscles were more active in the symptomatic group. During Valsalva, the PFM and EO were more active in the symptomatic group but there was no difference in the activation of the other muscles between groups. There was a significant interaction (group x pressure) for change in IAP (P = 0.047) but no significant interaction for change in vaginal pressure (VP) (P = 0.324). CONCLUSIONS: The symptomatic women displayed altered muscle activation patterns when compared to the asymptomatic group. The symptomatic women were unable to perform a voluntary PFM contraction using a localized muscle strategy, instead activating all the muscles of the abdomino-pelvic cavity. The potential for muscle substitution strategies reinforces the need for close attention to specificity when prescribing PFM exercise programs. 相似文献

The aim of this study was to assess pelvic floor muscle (PFM) strength and perception and its correlation with stress urinary incontinence (SUI). One hundred and one women were divided into two groups according to the presence (G1=51 patients) or absence (G2=50 patients) of SUI. Subjective [urine stream interruption test (UST), visual survey of perineal contraction and transvaginal digital palpation to assess pelvic muscle contraction] and objective evaluations of pelvic floor muscles in all patients were performed (vaginal manometry). During the UST, 25.5% of G1 patients and 80% of G2 patients were able to interrupt the urine stream (p<0.05). Digital evaluation of pelvic muscular contraction showed higher strength in G2 than in G1 patients (p<0.0001). Perineometer evaluation of PFM strength was significantly higher in the continent group (p<0.001). Pelvic floor muscle weakness in incontinent patients demonstrates the importance of functional and objective evaluation of this group of muscles.This revised version was published online in February 2005 with corrections to the third authors name.

The aims of the study were: (1) to assess women performing voluntary pelvic floor muscle (PFM) contractions, on initial instruction without biofeedback teaching, using transperineal ultrasound, manual muscle testing, and perineometry and (2) to assess for associations between the different measurements of PFM function. Sixty continent (30 nulliparous and 30 parous) and 60 incontinent (30 stress urinary incontinence (SUI) and 30 urge urinary incontinence (UUI)) women were assessed. Bladder neck depression during attempts to perform an elevating pelvic floor muscle (PFM) contraction occurred in 17% of continent and 30% of incontinent women. The UUI group had the highest proportion of women who depressed the bladder neck (40%), although this was not statistically significant (p=0.060). The continent women were stronger on manual muscle testing (p=0.001) and perineometry (p=0.019) and had greater PFM endurance (p<0.001) than the incontinent women. There was a strong tendency for the continent women to have a greater degree of bladder neck elevation than the incontinent women (p=0.051). There was a moderate correlation between bladder neck movement during PFM contraction measured by ultrasound and PFM strength assessed by manual muscle testing (r=0.58, p=0.01) and perineometry (r=0.43, p=0.01). The observation that many women were performing PFM exercises incorrectly reinforces the need for individual PFM assessment with a skilled practitioner. The significant correlation between the measurements of bladder neck elevation during PFM contraction and PFM strength measured using MMT and perineometry supports the use of ultrasound in the assessment of PFM function; however, the correlation was only moderate and, therefore, indicates that the different measurement tools assess different aspects of PFM function. It is recommended that physiotherapists use a combination of assessment tools to evaluate the different aspects of PFM function that are important for continence. Ultrasound is useful to determine the direction of pelvic floor movement in the clinical assessment of pelvic floor muscle function in a mixed subject population. 相似文献

Introduction and hypothesis
Interruption of urine flow during micturition has been used as an assessment of ability to voluntarily contract the pelvic floor muscles (PFM). However, the PFM are also activated during specific abdominal manoeuvres. This study aimed to assess the effect of similar abdominal manoeuvres on urine flow and compare this with the effect of PFM contraction.Methods
Eight healthy women, of mixed parity, contracted the abdominal muscles and the PFM during urine flow on separate occasions. Differences in urine flow were compared using paired t tests.Results
All participants were able to interrupt the urine stream using both muscle activation patterns. There was no difference in the time taken to interrupt urine flow (p?=?0.78) between the two patterns.Conclusions
These data provide evidence that specific abdominal muscle manoeuvres influence urethral closure in continent women, and this is probably mediated by concurrent activation of PFM during the abdominal task. 相似文献14.

AIMS: To evaluate the test-retest reliability of dynamometric measurements of the pelvic floor muscles (PFM) during speed and endurance tests. METHODS: Nineteen parous women suffering from stress urinary incontinence (SUI) participated in the study. Two PFM evaluation sessions were conducted using the dynamometric speculum. For the speed test, the women were instructed to contract maximally and relax as quickly as possible during a 15-s test period. The speed of contraction was quantified by the rate of force development of the first contraction and the number of contractions performed. The maximal strength value attained during the speed test was also extracted from the curves. For the endurance test, the subjects were asked to maintain a maximal contraction for 90 s. The normalized area under the force curve was utilized as the endurance parameter. The reliability of the data was evaluated using the generalizability theory. Two reliability estimates were calculated, the dependability indices (Phi) and the standard error of measurement (SEM), for one measurement session involving one trial. RESULTS: The indices of dependability obtained indicate that the reliability of the speed of contraction and endurance parameters are good (Phi=0.79-0.92). The corresponding SEMs were 1.39 N/s, 1 contraction, 1.00 N, and 298%*s for the rate of force development, number of contractions, maximal strength and normalized area, respectively. CONCLUSION: This study indicates that the speed of contraction and endurance parameters possess good test-retest reliability. The inclusion of these parameters in the PFM assessment is therefore highly recommended for assessing changes in PFM in incontinent women. 相似文献

AIMS: To assess how muscular fatigue deteriorates the modulation of pelvic contraction during increasing cough efforts. Furthermore, we investigated the correlation between the temporal course of pelvic floor activation during cough. METHODS: Informed consent was obtained from 20 women presenting with SUI and 6 continent women (overactive bladder syndrome [OAB]). Bladder pressure (BP) and external anal sphincter electromyographic activity (EAS EMGi) were recorded concomitantly during increasing cough efforts. Modulation of pelvic contraction was assessed before and after two types of intense pelvic exercise (Exercise #1: 10 successive strong cough efforts; Exercise #2: 10 pelvic contractions followed by a maximal pelvic contraction) at 0, 200, and 400 ml of bladder filling. We have also recorded electromyographic activity of external intercostal (EIC) muscles. RESULTS: Whereas the Exercise 1 had no effect on modulation, the Exercise 2 altered significantly the modulation of pelvic contraction during increasing cough efforts (P = 0.043) only in women presenting with SUI. The bladder filling volume seems to not significantly modify this modulation (P = 0.12). Median latency between the onset of the EAS EMGi and the onset of the EIC EMGi was -470 and -60 msec in OAB group and in SUI group, respectively (P = 0.012). There was a good correlation between mean latency (default of EAS EMGi pre-activation) and an altered modulation of pelvic contraction during increasing cough efforts (P = 0.040). CONCLUSIONS: Some women with SUI exhibit an altered pattern of the PFM response during increasing coughing efforts. The lack of this modulation of PFM response to stress may be one of the pathophysiologic factors of SUI. 相似文献

Our aim was to compare the urethral pressure response pattern to pelvic floor muscle contractions in 20–27 years old, nulliparous
continent women (n = 31) to that of continent (n = 28) and formerly untreated incontinent (n = 59) (53–63 years old) women. These women underwent urethral pressure measurements during rest and repeated pelvic muscle
contractions. The response to the contractions was graded 0–4. The young continent women showed a mean urethral pressure response
of 2.8, the middle-aged continent women 2.2 (NS vs young continent), and the incontinent women 1.5 (p < 0.05 vs middle-aged continent, p < 0.001 vs young continent). Urethral pressures during rest were significantly higher in the younger women than in both groups
of middle-aged women. The decreased ability to increase urethral pressure on demand seen in middle-aged incontinent women
compared to continent women of the same age as well as young women seems to be a consequence of a neuromuscular disorder rather
than of age. 相似文献

The aim of the present study was to describe co-activity patterns of the striated urethral wall muscle and the pelvic floor muscles (PFM) during contraction of outer pelvic muscles. Six healthy nulliparous physical education students, mean age 19.5 years (19–21) participated in the study. Concentric needle EMG and a Dantec amplifier were used for registrations. EMG activity was continuously recorded with the participants lying in a supine position. EMG was recorded during relaxation, contraction of the PFM. valsalva maneuver, coughing, hip adductor contraction, gluteal muscle contraction, backward tilting of the pelvis, and sit-ups. The procedure was performed with the needle in the striated muscle of the anterior wall of the urethra and then repeated with the needle set lateral to the urethra in the PFM. The results showed that the striated urethral wall muscle was contracted synergistically during PFM, hip adductor, and gluteal muscle contraction, but not during abdominal contraction. Both hip adduction, gluteal muscle, and abdominal muscle contraction gave synergistic contraction of the PFM. Thus the urethral wall striated muscle and the PFM react differently during abdominal contraction. © 1994 Wiley-Liss, Inc. 相似文献

Introduction and hypothesis
The purpose of this study was to determine pelvic floor muscle (PFM) function in hospitalized elderly women with urinary incontinence (UI).Methods
A cross-sectional study was performed using data of 704 patients, routinely collected by means of a clinical UI assessment.Results
Only 25.5% of the patients were able to perform normal PFM contractions (Oxford grading scale score ≥3); 74.5% were unable to contract their PFM or showed weak PFM activity without circular contraction or elevation of the vagina. Vulvovaginal mucosal dystrophy was noted in 84% of the patients. A significant positive correlation of PFM function was found to cognitive status (MMSE score), mobility (Tinetti performance score), and history of previous PFM training; a negative correlation of PFM function was found to patients’ age and vulvovaginal mucosal dystrophy, and no significant correlation to body mass index, parity, or history of hysterectomy.Conclusions
Targeted clinical UI assessment including digital vaginal palpation should be performed in all incontinent elderly women in order to detect PFM dysfunction and to optimize therapeutic measures. 相似文献19.

We describe the impact of genital trauma on pelvic floor function in a low-risk cohort of women after vaginal birth. Questionnaires
(Present Pain Intensity Scale, Incontinence Impact Questionnaire, Fecal Incontinence Score, and Intimate Relationship Scale)
were completed up to 12 weeks postpartum. Severity of trauma was recorded at delivery. Overall follow-up was 444/565 (79%).
Major trauma (trauma that involved perineal muscles or required suturing) occurred in 20%; 20% delivered intact. At 12 weeks,
10% complained of perineal pain; 24% reported anal (AI) and 27% urinary incontinence (UI). Women with trauma were no more
likely than those intact to complain of UI or AI, sexual inactivity, or perineal pain postpartum (all P = NS). Women with major trauma had weaker pelvic floor exercise strength than those who delivered intact or with minor trauma
(odds ration 3.06, 95% confidence interval 1.41–6.63). Pelvic floor complaints postpartum were common but not associated with
severity of genital trauma in a cohort of low-risk women. 相似文献

The aim of this study was to describe normal characteristics of spontaneous and voluntary pelvic muscle function in nulliparous healthy continent women and to assess the reaction of the pelvic floor to stress and fatigue. Ten nulliparous volunteers were recruited. Pelvic muscle strength was evaluated by palpation and perineal ultrasound. Kinesiological EMG and perineal ultrasound were performed to test for possible fatigue and to assess bladder neck mobility during coughing with a pre-contraction of the pelvic floor muscles. Bladder neck mobility did not increase after attempts to fatigue the pelvic floor muscles. Bladder neck descent was significantly less when the women were instructed to contract the pelvic floor muscles before coughing. The contraction of the pelvic floor muscles stabilizes the vesical neck in nulliparous women. 相似文献
