The role of pelvic floor muscle contraction in the genesis of anal canal pressure is not clear. Recent studies have suggested that vaginal distension increases pelvic floor muscle contraction. We studied the effects of vaginal distension on anal canal pressure in 15 nullipara asymptomatic women. Anal pressure, rest, and squeeze were measured using station pull-through manometry techniques with ...

BACKGROUND Patients referred for chronic constipation frequently report symptoms of straining, feeling of incomplete evacuation, or the need to facilitate defecation digitally (dyschezia). When such patients show manometric evidence of inappropriate contraction or failure to relax the pelvic floor muscles during attempts to defecate, they are diagnosed as having pelvic floor dyssynergia (Rome I...

INTRODUCTION Pelvic floor dysfunction affects 25% of women within the United States [1]. Pelvic floor dysfunction encompasses a group of disorders that occur because of weakened pelvic muscles and fascia after damage or trauma. Most significantly, a compromised levator ani muscle is thought to be responsible for the onset of these pelvic floor problems. By the year 2050, the number of women wit...

QUESTIONS Are there any differences in the displacement and endurance of an elevating voluntary pelvic floor muscle contraction in standing and in crook-lying? Are there any differences in these variables between males and females in either test position? DESIGN An experimental study. PARTICIPANTS Forty-five nulliparous female and 20 male participants aged 23 years (SD 3) with no symptoms o...

OBJECTIVE To investigate the pelvic floor muscle strength of the women andevaluateits possible correlation with sexual dysfunction. METHODS In this cross-sectional type study, stratified clusters were used for the sampling method. Index of Female Sexual Function (IFSF) worksheetwere used for questions on sexual function. The pelvic floor muscle strength of subjects was assessed byperineometer...

CONTEXT AND OBJECTIVE There is uncertainty in the literature regarding the theory that obstetric events and pelvic floor injuries give rise to lower risk of subsequent urinary incontinence among women delivering via cesarean section than among women delivering vaginally. The objective of this study was to assess the two-year postpartum prevalence of urinary incontinence and pelvic floor muscle ...

BACKGROUND Combined pelvic floor electromyography (EMG) and videocystourethrography (VCUG) during urodynamic investigation are the most acceptable and widely agreed methods for diagnosing detrusor external sphincter dyssynergia (DESD). Theoretically, external urethral sphincter pressure (EUSP) measurement would provide enough information for the diagnosis of DESD and could simplify the urodynam...

This study was a case series design. The objectives of the study were to investigate the ability of a motor learning intervention to change aberrant pelvic floor and diaphragm kinematics and respiratory patterns observed in subjects with sacroiliac joint pain (SIJP) during the active straight leg raise (ASLR) test. The ASLR test is a valid and reliable tool to assist in the assessment of load t...
