Dr Nazir Naimy and colleagues from Norway evaluated the effect of biofeedback, and electrostimulation in a randomized, clinical trial for the treatment of patients with postdelivery anal incontinence.
The patients received biofeedback or electrostimulation sessions 2 times daily for 8 weeks in each group.
The team evaluated females who sustained third-degree or fourth-degree perineal rupture with a mean age of 36 years in the study.
The research team randomized 19 patients to biofeedback, and 21 to electrostimulation treatment, of which 40 females completed the study.

The research team registered Wexner incontinence score, fecal incontinence quality of life scores, and reduced quality of life on visual analog scale before and after treatment.
Patients self-rating of treatment effect also was registered in both groups.
The team assessed that the primary outcome measure was the Wexner incontinence score.
The researchers observed no differences in treatment effect between groups.
The team of doctors found no improvement in Wexner score, reduced quality of life, or any of the fecal incontinence quality of life scores in either group.
Patients' self-rating of the treatment effect, however, showed a subjective improvement of symptoms both in the biofeedback, and in the electrostimulation group.
Dr Naimy's team concluded, "This study shows that there was no difference in effect between biofeedback and electrostimulation."
"Neither biofeedback nor electrostimulation treatments improved Wexner incontinence score, reduced quality of life, or fecal incontinence quality of life scores."
"Both treatments resulted in improvement of patients' subjective perception of incontinence control."
