Constipation and paradoxical puborectalis contraction in anismus and Parkinson's disease: a dystonic phenomenon?
Anismus, or constipation due to functional obstruction at the pelvic outlet by paradoxical contraction of the striated sphincter muscles during defaecation straining, is described in ten constipated patients and four patients with Parkinson's disease and constipation. The dysfunctional pattern of muscle recruitment resembled that characteristic of dystonia elsewhere in the body and was indistin...
متن کاملpuborectalis and external anal sphincter muscles
The innervation of the puborectalis and external anal sphincter muscles was studied in 32 patients with idiopathic (neurogenic) faecal incontinence, 12 of whom also had complete rectal prolapse, using transcutaneous spinal stimulation, transrectal pudendal nerve stimulation, single fibre EMG, anorectal manometry, and measurement of perineal descent. Fourteen normal subjects served as controls. ...

متن کاملAn Analysis of Factors Associated with Increased Perineal Descent in Women
PURPOSE Treatment of descending perineal syndrome is focused on personal etiology and on improving symptoms. However, the etiology of increased perineal descent (PD) is unclear. Therefore, the aim of the present study was to evaluate factors associated with increased resting and dynamic PD in women. METHODS From January 2004 to August 2010, defecographic findings in 201 female patients were r...
متن کاملParadoxical sphincter contraction is rarely indicative of anismus.
BACKGROUND Anismus is thought to be a cause of chronic constipation by producing outlet obstruction. The underlying mechanism is paradoxical contraction of the anal sphincter or puborectalis muscle. However, paradoxical sphincter contraction (PSC) also occurs in healthy controls, so anismus may be diagnosed too often because it may be based on a non-specific finding related to untoward conditio...
