In our experience, when assessing constipated patients, constipation is often due to defecation-related concerns rather than impaired bowel function or dyssynergic
defecation; thus, these factors may be of capital importance.
(1) Adult primary chronic constipation can be classified into 3 overlapping subtypes: colonic inertia, dyssynergic
defecation, and constipation-predominant irritable bowel syndrome.
Primary constipation consists of several overlapping subtypes, among which dyssynergic
defecation (DD) is relatively common [4, 5].
The straining test result was considered a dyssynergic
defecation pattern if there was an inappropriate increase or if the relaxation was <20% of the basal resting pressure.
In patients with dyssynergic
defecation and loss of stool, the goal of neuromuscular training is two-fold: 1) to correct the dyssynergia or incoordination of the abdominal, rectal, puborectalis, and anal sphincter muscles to achieve a normal and complete evacuation; and 2) to enhance rectal sensory perception in patients with impaired rectal sensation (Markland et al., 2008).
The "'Biofeedback treatment in chronically constipated patients with dyssynergic
defecation", article aimed to evaluate the effects of psychophysiological measures (EMG-activity during straining to defecate and anismus index), as well as in clinical variables on chronically constipated patients with dyssynergic
Some patients may have dyssynergic
defecation, which will not be helped with fiber.
Previous short-term randomized trials have demonstrated that biofeedback is effective in patients with dyssynergic
detrusor dysfunction in the apparently normal female.
The aim of this study was to evaluate the effects of electromyographic biofeedback training in chronically constipated patients with dyssynergic
Primary constipation can be classified into three categories: slow-transit constipation, dyssynergic
defecation, and normal-transit constipation.
Biofeedback success was 3.6-fold more likely in patients with pelvic floor dyssynergia at baseline, compared with those who were dyssynergic
