Pelvic floor exercises during and after pregnancy: a systematic review of their role in preventing pelvic floor dysfunction.

OBJECTIVE: To review the literature on the origin, anatomical rationale, techniques, and evidence-based effectiveness of peripartum pelvic floor exercises (PFEs) in the prevention of pelvic floor problems including urinary and anal incontinence, and prolapse. DATA SOURCES: Literature was reviewed for background information. MEDLINE, EMBASE, CINAHL, and proceedings of scientific meetings were searched for evidence-based data. A comprehensive literature search was performed to find all studies that involved the use of antepartum and/or postpartum PFEs. For the MEDLINE (1966 to 2002) and CINAHL (1980 to 2002) searches, the following key words were used: urinary incontinence (prevention and control, rehabilitation, therapy), fecal incontinence, exercise or exercise therapy, Kegel, muscle contraction, muscle tonus, muscle development, pelvic floor, pregnancy, puerperium, puerperal disorders. For the EMBASE (1980 to 2002) search, the following key words were used: micturition disorder (prevention, rehab, disease management, therapy), fecal incontinence, labour complication, pregnancy disorder, puerperal disorder, antepartum care, pregnancy, kinesiotherapy, exercise, pelvic floor, bladder. A manual search was performed of available abstracts presented at the annual scientific meetings of the International Continence Society (1997, 1999 to 2002), American Urogynecologic Association (1997 to 1998, 2000 to 2002), and International Urogynecological Association (1997, 1999 to 2002). Twelve studies evaluating the role of antepartum PFE were found, of which 3 randomized controlled trials (RCTs) comparing PFEs for the prevention of urinary incontinence to controls were included. Twelve studies evaluating postpartum PFEs for prevention of urinary incontinence were reviewed, of which 4 RCTs were included. Five studies evaluating postpartum PFEs for the prevention of anal incontinence were reviewed, of which 4 RCTs were included. Participants in the studies were primiparous women. DATA TABULATION AND INTEGRATION: Data were extracted using a standardized collection form. Quality of the data was evaluated using the Jadad scale. Where possible, a meta-analysis was conducted using a random effect model. Heterogeneity between trials was assessed and sensitivity analyses were performed. RESULTS: Antepartum PFEs, when used with biofeedback and taught by trained health care personnel, using a conservative model, does not result in significant short-term (3 months) decrease in postpartum urinary incontinence, or pelvic floor strength. Postpartum PFEs, when performed with a vaginal device providing resistance or feedback, appear to decrease postpartum urinary incontinence and to increase strength. Reminder and motivational systems to perform "Kegel" exercises are ineffective in preventing postpartum urinary incontinence. Postpartum PFEs do not consistently reduce the incidence of anal incontinence. CONCLUSION: Postpartum PFEs appear to be effective in decreasing postpartum urinary incontinence. Data regarding the effect of PFEs on prevention of anal incontinence are lacking, and also on its prevention of prolapse.

Variance of vestibular-evoked myogenic potentials.

OBJECTIVES/HYPOTHESIS: Vestibular-evoked myogenic potential (VEMP) has been thought to originate from sacculus. The variance of this potential and the effectiveness of the adjustments of pInII amplitudes using average muscle tonus of ipsilateral sternocleidomastoid muscle were evaluated. In addition, clinical application of VEMP was examined in patients with acoustic tumors (ATs) and vestibular neurolabyrinthitis (VNL). STUDY DESIGN: Prospective evaluation of the VEMP in 18 normal volunteers and 6 patients. METHODS: Variance and left-right difference of each parameter, including pI latency, nII latency, pInII amplitude, and threshold, was analyzed. Input-output function of pInII amplitude was evaluated. Average muscle tonus was calculated in 20 ears and applied for adjustment of pInII amplitude. Sensitivity of each parameter of VEMP was examined in 3 patients with ATs and 3 patients with VNL. RESULTS: VEMP was present in all 36 ears of 18 control subjects. Thresholds of VEMP for normal subjects were 80 to 95 dB normal hearing level (nHL). The muscle tonus affected pInII amplitude significantly; however, no statistically significant improvement was observed in test-retest investigation after adjustment using muscle tonus. The threshold of the affected side was elevated compared with the non-affected side in all patients with ATs, whereas 2 of 3 patients showed normal pInII-ratio. One patient with VNL presented normal VEMP, whereas 2 patients presented no VEMP to the highest stimulus intensity. CONCLUSIONS: Interaural difference of thresholds might be the most useful parameters. Adjustment using average muscle tonus is not necessary when the subject is able to get sufficient muscle tonus.

Pre-anesthetic oral clonidine is effective to prevent post-spinal shivering.

BACKGROUND: Shivering is a common event during spinal anesthesia. Customarily we just treat it rather than prevent it. This study was designed to evaluate the efficacy of oral clonidine as a premedication to prevent post-spinal shivering. METHODS: One hundred males of ASA physical status I-III, aged above 40, scheduled for elective urological surgery under spinal anesthesia, were included in this study. All participants were randomly divided into the clonidine and control groups. They received either oral clonidine 150 micrograms (n = 48) or placebo (n = 52) 90 min before spinal anesthesia in a double-blind fashion. Spinal blockade was induced with heavy bupivacaine to a dermatomal level near T10. The shivering was graded as: none, no perceptible tension of muscles observed; mild, slight muscle tonus (masseter muscle); moderate, real shivering (proximal muscles); and severe, generalized shivering (whole body). The tympanic membrane temperature was recorded 30 min after spinal anesthesia. Data were expressed as mean +/- standard deviation. Chi-square and Student's t-test were used. A p value less than 0.05 was considered statistically significant. RESULTS: The incidence of post-spinal shivering, which was graded as none, mild, moderate, and severe, showed statistically significant differences (p < 0.05) between clonidine 150 micrograms and placebo (83% vs. 42%, 10% vs. 6%, 10% vs. 19%, 0% vs. 33%, respectively) during the 30 min immediately after spinal anesthesia. The respective mean tympanic temperature in oral clonidine and placebo groups showed no difference (clonidine vs. control = 35.9 +/- 0.8 degrees C vs. 35.9 +/- 0.7 degrees C). CONCLUSIONS: Pre-anesthetic medication with oral clonidine 150 micrograms is effective to prevent post-spinal shivering in patients undergoing elective urological surgery.

The 10th Bielschowsky Lecture. Changes in strabismus over time: the roles of vergence tonus and muscle length adaptation.

Patients with long-standing unilateral strabismus, such as "sensory" exotropia in the absence of fusion, or esotropia with unilateral amblyopia, typically show bilateral deviations under anesthesia, often symmetric. Forced ductions usually show symmetric muscle tightness. Changes in extraocular muscle lengths thus appear to occur primarily bilaterally, whether fusion is present or not. With skeletal muscles responding to changes in stimulation by the gain or loss of sarcomeres, it is likely that abnormal or unguided vergence tonus, which changes the lengths of the extraocular muscles bilaterally, is largely responsible for changes in the angle of strabismus over time. This mechanism helps explain the development of [1] increasing "basic" deviations in accommodative esotropia; [2] torsional deviations with apparent oblique muscle "overaction/underaction" and A and V patterns; [3] recurrent esotropia with early presbyopia; [4] occasional divergence insufficiency in presbyopes; and [5] basic cyclovertical deviations that mimic superior oblique muscle paresis.

The effect of biofeedback physical therapy in men with Chronic Pelvic Pain Syndrome Type III.

UNLABELLED: Recent studies suggest that the symptoms of chronic non-bacterial prostatitis (CP) or Chronic Pelvic Pain Syndrome (CPPS) may be due to or associated with pelvic floor muscle dysfunction. Therapies aimed to improve relaxation and proper use of the pelvic floor muscles such as biofeedback physical therapy and pelvic floor re-education are expected to give symptom improvement. The objective of this study was to evaluate the effect of biofeedback physical therapy on the symptoms of men with CPPS. MATERIALS AND METHODS: Between March 2000 to March 2004, 33 consecutive men were diagnosed with CP/CPPS based on history including the NIH-CPSI questionnaire and physical examination including pelvic floor muscle tonus, urinalysis, uroflowmetry with residual urine measurement and transrectal ultrasonography of the prostate. All patients participated in a pelvic floor biofeedback re-educating program. A rectal EMG probe was used to measure resting tone of the pelvic floor muscles and was helpful for instruction pelvic floor muscles contraction and relaxation. RESULTS: Two of the 33 men dropped out. In the remaining 31 men, mean age 43.9 years (range 23-70), the mean total Chronic Prostatitis Symptom Index (NIH-CPSI) changed from 23.6 (range 11-34) at baseline to 11.4 (range 1-25) after treatment (p<0.001). The mean value of the pelvic floor muscle tonus was 4.9 at diagnosis (range 2.0-10.0) and decreased to 1.7 (range 0.5-2.8) after treatment (p<0.001). CONCLUSIONS: Our study clearly demonstrates a significant effect of biofeedback physical therapy and pelvic floor re-education for CP/CPPS patients, leading to a significant improvement of the symptom score. The correlation between the pelvic muscle tonus results with NIH-CPSI score is highly suggestive that the pelvic floor plays an important role in the pathophysiology of CP/CPPS.

Dystonic posturing associated with putaminal hyperperfusion depicted on subtraction SPECT.

PURPOSE: Dystonic posturing (DP) is one of the most reliable lateralizing indicators for temporal lobe epilepsy (TLE). We evaluated the ictal hyperperfusional areas in patients with DP by using ictal-interictal subtraction single-photon emission computed tomography (SPECT). METHODS: Ninety-seven patients were treated surgically for intractable TLE, and 39 patients underwent ictal and interictal SPECT studies with the same isotope. These patients were divided into three groups: group I with DP of the contralateral side extended to the epileptogenic focus, group II with elevated muscle tonus but without DP, and group III without DP or alteration of muscle tonus. Ictal, interictal SPECT and thin-slice magnetic resonance imaging (MRI) were overlaid by using the automatic multimodality registration program to construct ictal-interictal subtracted images of SPECT on MRI. RESULTS: Thirteen patients belonged to group I; 14, to group II; and 12, to group III. A statistically significant difference in hyperperfusion rate was observed in the putamen (10 patients in group I, three in group II and two in group III; p < 0.01) and mesial temporal lobe (10 patients in group I, seven in group II, and two in group III; p < 0.05) on the ipsilateral side of the epileptogenic focus. No statistically significant difference was observed for other ictal symptoms except ipsilateral upper-limb automatism (eight patients in group I, three in group II, and none in group III; p < 0.01). CONCLUSIONS: A strong correlation between DP and hyperperfusion in the putamen and mesial temporal lobe was demonstrated. Some patients showed a wide hyperperfusion area extending from the mesial temporal lobe to putamen, which may correspond to the propagation of epileptic discharges. Our results suggest a correlation between hyperperfusion of putamen and contralateral dystonic posturing.
