Deep Diaphragmatic Breathing-Anatomical and Biomechanical Consideration.

Background: Deep diaphragmatic breathing (DDB) involves slow and fully contraction of the diaphragm with expansion of the belly during inhalation, and slow and fully contraction of the abdominal muscles with reduction of the belly during exhalation. It is the key component of the holistic mind-body exercises commonly used for patients with multimorbidity. Purpose: The purpose of this study was to re-visit and address the fundamental anatomical and biomechanical consideration of the DDB with the relevant literature. Method: Peer-reviewed publications from last the 15 years were retrieved, reviewed, and analyzed. Findings: In this article, we described the updated morphological and anatomical characteristics of the diaphragm. Then, we elucidated in a biomechanical approach how and why the DDB can work on the gastrointestinal, cardiopulmonary, and nervous systems as well as on regulating the intra-abdominopelvic pressure and mind-body interaction to coordinate the diaphragm-pelvic floor-abdominal complex for a variety of physical and physiological activities. Conclusion: Understanding of this updated DDB knowledge may help holistic healthcare professionals including holistic nurses provide better patient education and care management during the DDB or DDB-based mind-body intervention time.

Laparoscopic implantation of electrodes for bilateral neuromodulation of the pudendal nerves and S3 nerve roots for treating pelvic pain and voiding dysfunction.

INTRODUCTION AND HYPOTHESIS: The objective of this video is to describe the technique for laparoscopic implantation of electrodes for bilateral neuromodulation of S3 and pudendal nerves. We report a successful case of a 48-year-old woman with spina bifida occulta referred with a 14-year history of intense acyclic pelvic pain, urinary hesitancy, and intermittent flow refractory to various conservative measures. METHODS: The procedure began with the removal of two previously placed InterStims. A quadripolar electrode was then laparoscopically inserted into Alcock's canal and attached to the pelvic pectineal line. Another lead was placed juxtaneurally to S3. Lead contacts were then exteriorized, and the peritoneum closed. The same procedure was then performed on the contralateral side. The leads were connected to a 16-pole rechargeable pulse generator. Postoperatively, the patient developed an acute dissection and partial thrombosis of the external iliac artery, which was treated endovascularly. RESULTS: Complete pain resolution was observed with simultaneous S3 and pudendal stimulation, with pudendal stimulation turned off for voiding. CONCLUSIONS: We conclude that laparoscopic implantation of neuromodulation electrodes allows simultaneous stimulation of S3 and pudendal nerves, providing more programming options and possibly increasing success rates in complex pelvic floor dysfunction cases.

Transvaginal Pelvic Floor Muscle Injection Technique: A Cadaver Study.

INTRODUCTION: Women with pelvic floor dysfunction can have tender areas on vaginal examination, which can be treated with trigger-point injections. There are no publications to evaluate the accuracy of pelvic floor muscle injections. METHODS: Trigger-point injections were performed on 2 fresh cadaveric pelvises using a curved nasal cannula guide and 7-in spinal needle. This was performed using our standard template of 2 sets of injections at the 1-, 3-, and 5-o'clock positions distally and proximally. The first pelvis was dissected to examine dye penetration. Based on these results, we modified our technique and repeated the injections on the second cadaver. We dissected the second pelvis and compared our findings. RESULTS: The 1-o'clock proximal and distal injections stained the obturator internus and externus near the insertion at the ischiopubic ramus. The 3-o'clock injections stained the midbody of the pubococcygeus and puborectalis. The distal 5-o'clock position was too deep and stained the fat of the ischiorectal space. The proximal 5-o'clock injection stained the area of the pudendal nerve. Our goal at the distal 5-o'clock position was to infuse the iliococcygeus muscle, so we shortened the needle depth from 2 to 1 cm beyond the cannula tip. In our second dissection, the distal 5-o'clock injection again stained only the fat of the ischiorectal space. CONCLUSIONS: This is the first study to characterize the distribution of pelvic floor muscle injections in a cadaver model and confirms the ability to deliver medications effectively to the pelvic floor muscles.

The integrated continence system: a manual therapy approach to the treatment of stress urinary incontinence.

Stress urinary incontinence (SUI) constitutes a large-scale public health concern. The integrated continence system (ICS) developed by the authors is an evidence-based model that demonstrates how urinary incontinence is maintained through the interaction of three structural systems (intrinsic urethral closure, urethral support and lumbopelvic stability) and three modifiable factors (motor control, musculoskeletal and behavioural). The purpose of the ICS is first, to demonstrate the important role that manual physiotherapists can play in the treatment of SUI and second, to guide clinical practice decisions in order to improve clinical outcomes among women with SUI.

MRI-based registration of pelvic alignment affected by altered pelvic floor muscle characteristics.

BACKGROUND: Pelvic floor muscles have potential to influence relative pelvic alignment. Side asymmetry in pelvic floor muscle tension is claimed to induce pelvic malalignment. However, its nature and amplitude are not clear. There is a need for non-invasive and reliable assessment method. An intervention experiment of unilateral pelvic floor muscle activation on healthy females was performed using image data for intra-subject comparison of normal and altered configuration of bony pelvis. METHODS: Sequent magnetic resonance imaging of 14 females in supine position was performed with 1.5 T static body coil in coronal orientation. The intervention, surface functional electrostimulation, was applied to activate pelvic floor muscles on the right side. Spatial coordinates of 23 pelvic landmarks were localized in each subject and registered by specially designed magnetic resonance image data processing tool (MPT2006), where individual error calculation; data registration, analysis and 3D visualization were interfaced. FINDINGS: The effect of intervention was large (Cohen's d=1.34). We found significant differences in quantity (P<0.01) and quality (P=0.02) of normal and induced pelvic displacements. After pelvic floor muscle activation on the right side, pelvic structures shifted most frequently to the right side in ventro-caudal direction. The right femoral head, the right innominate and the coccyx showed the largest displacements. INTERPRETATION: The consequences arising from the capacity of pelvic floor muscles to displace pelvic bony structures are important to consider not only in management of malalignment syndrome but also in treatment of incontinence. The study has demonstrated benefits associated with processing of magnetic resonance image data within pelvic region with high localization and registration reliability.

Pelvic floor muscle biofeedback in the treatment of urinary incontinence: a literature review.

Biofeedback is efficacious in the training of the pelvic floor musculature in order to enhance continence. This article reviews the anatomy and physiology of micturition as the underlying rationale for pelvic floor muscle biofeedback in the treatment of urinary incontinence. It critically reviews 28 studies published in peer reviewed journals from 1975 to 2005 that were prospective, randomized studies with parametric statistical analyses, operationally defined patient selection criteria, treatment protocols and outcome measures. The overall mean treatment improvement for patients undergoing biofeedback for urinary incontinence was 72.61%. In 21 of 35 (60%) paired comparisons, biofeedback demonstrated superior symptomatic outcome to control or alternate treatment groups. Larger studies and a standardization of technology and methodology are required for more conclusive determinations.

A new minimally invasive procedure for pudendal nerve stimulation to treat neurogenic bladder: description of the method and preliminary data.

AIMS: Pudendal nerve stimulation has beneficial effects on numerous pelvic floor function impairments such as urinary and/or fecal incontinence, retention, and constipation. In preceding literature the implant technique required a fairly complex and invasive surgery, although recent advances with percutaneous placement of the lead through an introducer have made the procedure much less invasive. We performed staged procedure similar to that of sacral neuromodulation (SNM) to place tined lead near the pudendal nerve, using neurophysiological guidance that allowed accurate pudendal nerve stimulation through either perineal or posterior approach. We have named this approach chronic pudendal nerve stimulation (CPNS). METHODS: Fifteen neurogenic patients (eight male, seven female) with symptoms of urge incontinence due to neurogenic overactive bladder underwent CPNS. All patients had complete neurophysiological and urodynamic evaluation at baseline and follow-up and were asked to complete voiding and bowel diary for 7 days. RESULTS: During screening, average number of incontinent episodes per day decreased from 7+/-3.3 to 2.6+/-3.3 (P<0.02, paired t-test). Eight patients became continent, two improved by more than 88% (from 9 to 1 daily incontinence episode) and two patients reduced the number of incontinence episodes by 50%. The implantable pulse generator (IPG) was subsequently implanted in those 12 patients. Three patients without improvement did not continue to second stage. In implanted patients with 6 months follow-up, urodynamic evaluation showed an objective improvement in the maximum cystometric capacity which increased from 153.3+/-49.9 to 331.4+/-110.7 ml (P<0.01, paired t-test). The maximum pressure decreased from 66+/-24.3 to 36.8+/-35.9 cmH2O (P=0.059, paired t-test). Eight patients reported significant improvement in bowel function. CONCLUSION: Chronic pundedal nerve stimulation is feasible. Neurophysiological guidance is mandatory to place the lead near the pudendal nerve either using perineal or posterior approach. Further studies must be carried out to identify the best stimulation parameters and to verify the long term results.

Front and rear: the pelvic floor is an integrated functional structure.

The pelvic floor is a muscular structure, pierced by the urologic, genital and distal intestinal tract. This structure is not a frozen but a functional unit. Normal function can thus be replaced by dysfunctions of several kinds, overlapping voiding, sexual, genital and defecatory behaviour. For instance, vaginismus is akin to anismus and vesicourethral dyssynergia. Recent recognition of the medicosurgical consequences of sexual abuse has shown that many urologic, genital and digestive dysfunctions are sort of a body signature of the trauma, which must be dealt with if the symptom is to disappear. If the pelvic floor is integrated, unsuspected pathology will lie outside of the spectrum of activities of a given specialty, and thus urologists, gynecologists, gastroenterologists and colorectal surgeons should not only exchange, but should also be aware of the pathologies of neighbouring specialties. This paper elaborates on a more holistic vision of pelvic floor function including sexuality. Out of this, a number of different hypotheses are elaborated in the different spheres of activities, about different pathologies, their basic cause, and how they could be dealt with.

Female pelvic floor functions, dysfunctions, and behavioral approaches to treatment.

This article has reviewed normal pelvic floor function and the type of evaluation and treatment programs that should be offered to the woman who presents with pelvic floor dysfunction. Pelvic floor muscle contraction is an acquired function. It is not innate. Development of pelvic floor muscle strength requires specificity training and dedication to an exercise program. It is imperative that women be educated about the functions and dysfunctions of the pelvic floor complex in order to promote preventive rather than restorative benefits of pelvic floor exercise. Exercise programs should be specific to the type of pelvic floor muscle dysfunction and its causes. Behavioral treatment options focus on traditional physical therapy techniques of education, therapeutic exercise, and the use of physical modalities that aid in the restoration of muscle function. Exercises for the pelvic floor should be part of every woman's fitness regime. Health care providers, health educators, and fitness personnel need to ask women more questions about pelvic floor function, encourage women to exercise these muscles, and to seek medical care for their dysfunctions. Only then will the magnitude and prevalence of pelvic floor muscle dysfunctions receive the attention that they need.
