Plain-language summary

This study has been completed. The following is a brief description of the aims, methods, and results of the study: Previous small studies suggest that chronic proctalgia (chronic recurring pain in the anal canal or rectum), which is also called levator ani syndrome, can be treated with biofeedback to teach relaxation of pelvic floor muscles, or electrogalvanic stimulation (electrical stimulation to relax muscles), or massage of pelvic floor muscles. The aim of this study was to compare the effectiveness of these three treatments, to determine how they work physiologically, and to identify which patients are most likely to benefit. Methods: Subjects had to meet the diagnostic criteria for chronic proctalgia and to report pain at least once a week. They had to also be free of medical or psychiatric disorders that could explain their chronic proctalgia. Patients qualified to enter the study were separated into two groups based on whether they reported tenderness when the examining physician pressed on the levator ani muscles of the pelvic floor. All 157 patients who were enrolled received 9 sessions of psychological counseling plus biofeedback or electrogalvanic stimulation or massage. The results of treatment were assessed at 1, 3, 6, and 12 months after the end of treatment.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: Recurring episodes of pain or aching in the anal canal or rectum for at least 12 weeks in the previous year. Episodes last at least 20 minutes. Pain must occur at least weekly during a 4-week run-in. Exclusion Criteria: Other medical or psychiatric diagnoses that could explain recurring rectal pain. Daily use of psychotropic medications.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
