Abstract
Pelvic floor disorders are a common source of morbidity in the developed world.
The incidence increases with age, parity, and obesity. The need of pelvic floor services is expected to grow at twice the population rate in the future.
Obstructed defecation syndrome is a well-defined symptom complex consisting of excessive straining at stool, need for perineal splinting, and incomplete rectal evacuation
This study was carried out prospectively on 50 patients, 25 patients (group A) received sessions of 30 minutes duration each of bilateral posterior tibial nerve stimulation, three times weekly over a period ranging between 6 to 12 weeks according to the patient improvement and the other 25 patients (group B) took medical treatment in the form of dietary modification, including fiber and fluid supplementation and osmotic laxatives.
The aim of this work is to study the effect of bilateral trasncutaneous posterior tibial nerve stimulation in the treatment of obstructed defecation without anatomic alteration in comparison to patients only taking medical treatment.
There was statistically significant difference for both groups and between the two groups in comparison between pre-treatment and after 6 weeks as regards MODS score and PAC-QoL score.
As regard the quantitative electromyography on pelvic floor muscles in group A (bilateral posterior tibial nerve stimulation), there was statistically significant difference between pre-treatment and after 6 weeks regarding the amplitude, number of turns and duration.
