AIM To evaluate female runners' pelvic floor muscles using three-dimensional ultrasonography (3DUS) and surface electromyography (SEMG). MATERIAL AND METHODS A cross-sectional study was conducted on 24 female runners. SEMG was performed using surface electrodes inserted in the vagina. 3DUS was performed using perineal convex transducer. SEMG was evaluated at rest and with maximum voluntary co...
OBJECTIVE A Valsalva maneuver is used clinically and on imaging in order to determine female pelvic organ prolapse. We have examined the potential confounding effect of levator co-activation at the time of a Valsalva maneuver and the impact of repetition with biofeedback instruction. METHODS Fifty nulliparous women at 36-38 weeks' gestation received 3D/4D translabial ultrasound investigation ...
OBJECTIVE Our objective was to use a combination of axial MR source images and three-dimensional (3D) models to describe the anatomy of the normal pelvic floor in young nulliparous women and to measure the volume of the levator ani. SUBJECTS AND METHODS Ten healthy nulliparous female volunteers (average age, 27 years) underwent T2-weighted MR imaging of the pelvis. Three-dimensional color-cod...
One of the characteristic features of the East Asian person's eyelids is the lack of a supratarsal fold. A relaxed upper eyelid skin, due to the lack of supratarsal fixation, causes coverage of the tarsal margin of the upper eyelid. Thus the palpebral fissure looks smaller, giving a slit-eye appearance. Unlike those lids with a natural supratarsal crease, the levator palpebrae muscle and/or apo...
The regenerating levator ani muscle of the rat is known to retain its sensitivity to the effects of testosterone. To determine whether hormonal sensitivity of the regenerating muscle is purely myogenic or requires some interaction with the pudendal nerve or the local humoral environment, levator ani muscles were freely grafted in place of the soleus or extensor digitorum longus muscles in norma...
The intrinsic tongue muscle, genioglossus, and soft palatal muscles, tensor palatini, levator palatini and palatoglossus, are known to exhibit phasic respiratory activity and to respond reflexly to negative pressure in man, which may be important in the maintenance of upper airway patency. We hypothesized that the palatopharyngeus muscle should also have respiratory activity and increased activ...
OBJECTIVE The objective of the study was to develop a model of the female pelvic floor to study levator stretch during simulated childbirth. STUDY DESIGN Magnetic resonance data from an asymptomatic nulligravida were segmented into pelvic muscles and bones to create a simulation model. Stiffness estimates of lateral and anteroposterior levator attachments were varied to estimate the impact on...
Blepharoptosis is an abnormally low position of the upper eyelid in relation to eyeball due its omission. The method surgical treatment blepharoptosis depends on function levator. aim . To analyze results partial various etiology by dosed muscle-conjunctival resection cartilage. Material and methods We operated 78 patients (82 eyes) with blepharoptosis, among them congenital – 34 people (36 eye...
BACKGROUND Pelvic organ prolapse (POP) is a condition affecting more than half of the women above age 40. The estimated lifetime risk of needing surgical management for POP is 11%. In patients undergoing POP surgery of the anterior vaginal wall, the re-operation rate is 30%. The recurrence risk is especially high in women with a levator ani defect. Such defect is present if there is a partially...
