Splinting during a bowel movement means using your hand to press against the vagina, perineum, or nearby tissue to help stool pass. It sounds unusual if you have never heard of it, but it is remarkably common among people with pelvic floor issues, and it works. One MRI study found that splinting improved or completely corrected the underlying anatomical defect in nearly all women who used the technique. The reasons you might need to splint, the anatomy driving it, and the practical details of doing it safely are more straightforward than you might expect.
What Splinting Actually Is
Splinting is a self-help maneuver for getting stool out when straining alone does not do the job. The person applies external or internal pressure with their fingers to support weakened tissue, essentially giving the rectal wall a backstop so stool can move forward and out. People who splint typically press in one of three locations: inside the vagina (pushing backward against the rectal wall), on the perineum (the tissue between the vagina and anus), or on the buttock near the anus. In an imaging study of 29 women who reported needing manual splinting, about 59% splinted vaginally, 31% on the perineum, and 10% on the buttock area. MRI confirmed that in all but one of those women, the maneuver improved or fully corrected the structural problem causing their difficulty.
1PubMed Central. Assessment of Women With Defecatory Dysfunction and Manual Splinting Using Dynamic Pelvic Floor Magnetic Resonance ImagingThe word “splinting” comes from the same idea as splinting a broken bone: you are bracing a structure that cannot hold its shape on its own. In this case, the structure is the wall between the rectum and the vagina (or the surrounding pelvic floor), which has weakened enough that stool gets trapped in a pocket rather than moving straight through. People sometimes discover splinting on their own, without a doctor ever mentioning it, because the instinct to press against bulging tissue turns out to be anatomically sound.
Why the Rectal Wall Bulges in the First Place
The most common anatomical reason behind the need to splint is a rectocele, a bulge where the front wall of the rectum pushes into the back wall of the vagina. When stool arrives in the rectum, it can slide into that pocket instead of heading toward the anal opening. The person feels like stool is “right there” but cannot push it out no matter how hard they strain. In the MRI study mentioned above, about 86% of the women who splinted had a rectocele. Most also had more than one pelvic floor defect happening at the same time: roughly 72% had multiple structural issues, including bladder prolapse and pelvic muscle tears alongside the rectocele.
1PubMed Central. Assessment of Women With Defecatory Dysfunction and Manual Splinting Using Dynamic Pelvic Floor Magnetic Resonance ImagingRectoceles are extremely common. Many women have a small one and never notice it. They become a problem when they are large enough to trap stool. A study of 260 women with pelvic organ prolapse found that those with posterior vaginal wall prolapse (the type that involves the rectum bulging forward) were significantly more likely to report obstructive symptoms: about 36% reported needing to splint, compared with 14% of women without that type of prolapse. They also reported more straining and a persistent feeling of incomplete emptying.
2International Journal of Gynecology & Obstetrics. Clinical significance of obstructive defecatory symptoms in women with pelvic organ prolapseThe causes of rectocele and related pelvic floor weakness include vaginal childbirth, aging, chronic constipation, heavy lifting, and genetic predisposition. Childbirth is the biggest single contributor, because the pelvic floor tissues stretch and sometimes tear during delivery. But rectoceles also develop in women who have never been pregnant, and the condition is not exclusive to older adults, although it becomes more common with age.
It Is Not Always a Rectocele
A rectocele is the most frequent reason for needing to splint, but it is not the only one. Some people have a coordination problem called dyssynergic defecation, where the muscles of the pelvic floor and abdomen do not work together properly during a bowel movement. Instead of relaxing the pelvic floor while pushing with the abdomen, the pelvic floor muscles tighten, essentially closing the exit. This affects up to half of people with chronic constipation and is considered an acquired behavioral problem rather than a structural one.
3PubMed Central. Diagnosis and Treatment of Dyssynergic DefecationSplinting can help with dyssynergic defecation too, because the manual pressure provides external support that partially compensates for the uncoordinated muscles. But the key difference is that dyssynergic defecation is often treatable through retraining the muscles (more on that below), while a rectocele is a structural issue that may require ongoing management. If you find yourself needing to splint regularly, knowing which problem you are dealing with affects what long-term solutions make sense.
An interesting detail from research on stool consistency: one study found that stool quality was actually more relevant to obstructed defecation symptoms than the presence of a rectocele itself. Hard, lumpy stool is more likely to get trapped in a rectocele pocket, while softer stool passes through more easily even when the structural defect is present. This is why many clinicians recommend fiber, adequate water, and sometimes a stool softener as first-line approaches before anything more involved.
4PubMed. Rectocele or stool quality: what matters more for symptoms of obstructed defecation?How to Splint Safely
If you have already figured out that splinting helps you evacuate, here is how to do it with the least risk of irritation or injury. The three main approaches match the three locations identified in research: vaginal, perineal, and perianal.
- Vaginal splinting: Insert one or two clean fingers into the vagina and press firmly backward, toward the rectum. You are essentially pushing the bulging rectal wall back into place so stool can move past the pocket. This is the most common technique and was used by the majority of women in the MRI study. You will typically feel the bulge become firmer when you bear down, and pressing against it redirects stool toward the anal opening.
- Perineal splinting: Press firmly with your fingers on the perineum, the area of skin between the vaginal opening and the anus. This supports the tissue from below and can reduce the degree of perineal descent (the pelvic floor dropping too far when you push). Some people find this is enough support to empty without needing to insert a finger.
- Perianal splinting: Press against the tissue beside or behind the anus, near the buttock. This is less common but can help when the obstruction is lower in the rectal canal.
Whichever approach you use, wash your hands before and after. Use gentle but firm pressure; you are not trying to dig out stool, just providing structural support so your normal pushing effort can work. If vaginal splinting feels uncomfortable, a small amount of water-based lubricant can help. Avoid sharp nails, and stop if you notice bleeding or significant pain, as that warrants a conversation with a doctor.
Posture Changes That Reduce the Need to Splint
Changing your position on the toilet can reduce straining and sometimes eliminate the need for splinting altogether, especially if your symptoms are mild. The underlying principle is straightening the angle between the rectum and the anal canal. When you sit on a standard toilet, your hips are at roughly a 90-degree angle, which creates a bend in the rectum. Squatting opens that angle, allowing stool to pass more directly.
Most people are not going to install a squat toilet at home, but a simple footstool placed in front of the toilet achieves much of the same effect by raising your knees above your hips. Research results on footstools are mixed but lean positive. A scoping review found that some studies showed footstools reduced straining time and effort in healthy volunteers, while one study of constipated patients found the footstool changed the hip angle without improving simulated defecation measures. An older study of patients with obstructed defecation found that footstools reduced evacuation time, particularly when the person also leaned their upper body forward.
5PubMed Central. Sitting vs. squatting: a scoping review of toilet postures and associated health outcomesA separate study on a commercially available “defecation posture modification device” (essentially a branded footstool) found that it improved the sensation of complete emptying and reduced straining in healthy volunteers, with shorter bowel movement durations. The researchers attributed the effect to the squatting-like position straightening the anorectal canal, increasing rectal pressure, and possibly relaxing the pelvic floor muscles.
6PubMed Central. Implementation of a Defecation Posture Modification Device Impact on Bowel Movement Patterns in Healthy SubjectsIn practice, the best approach for someone who splints is to combine posture modification with the splinting maneuver. Put your feet on a stool, lean forward slightly, and then splint if you still need to. The posture change reduces how much manual pressure you need, which makes the process faster and less uncomfortable.
When Splinting Signals Something Worth Investigating
Occasional splinting during a bout of constipation is not necessarily a sign that something is wrong. But if you find yourself needing to splint most of the time, or if the difficulty is getting worse, it is worth seeing a clinician who specializes in pelvic floor issues. The reason is that splinting treats the symptom (stool not coming out) without addressing the underlying cause, and some of those causes are treatable.
Clinicians use a few different tests to figure out what is going on. The balloon expulsion test is the simplest: a small balloon is placed in the rectum, inflated with water, and you are asked to push it out. Inability to expel it suggests a problem with evacuation mechanics. A meta-analysis of diagnostic studies found that this test picks up about three-quarters of people with defecatory disorders, with reasonable specificity.
7PubMed. Diagnostic value of balloon expulsion test and anorectal manometry in patients with constipation: a systematic review and meta-analysisFor more detailed information, specialized MRI (called MR defecography) can show exactly what is happening to the pelvic floor structures during the act of bearing down. This is the type of imaging that was used in the splinting study mentioned earlier, and it can distinguish between a rectocele, a muscle coordination problem, and other structural issues like an enterocele (small bowel dropping into the pelvis). One recent study specifically looked at using MR defecography to distinguish “true” dyssynergic defecation from structural evacuation problems in patients whose initial pressure testing had suggested dyssynergia, highlighting that the two conditions can mimic each other on simpler tests.
8PubMed. The diagnostic value of magnetic resonance defecography in differentiating evacuation disorders among patients with manometric dyssynergiaBiofeedback and Pelvic Floor Retraining
If the problem turns out to be dyssynergic defecation rather than a structural defect, the most effective treatment is biofeedback therapy. This is a form of physical therapy where sensors placed near the pelvic floor muscles give you real-time feedback on what those muscles are doing while you try to evacuate. The goal is to retrain the coordination: learning to relax the pelvic floor while pushing with the abdominal muscles, instead of tightening everything at once. Biofeedback has demonstrated clear benefits for chronic constipation caused by dyssynergic defecation, and it also helps with other pelvic floor conditions like fecal incontinence.
9PubMed Central. Biofeedback for Pelvic Floor DisordersSessions are typically done weekly over two to three months, though protocols vary. The retraining sticks for most people, which makes biofeedback a genuine fix rather than an ongoing management strategy. It does require access to a pelvic floor physical therapist, and availability can be limited depending on where you live. But for people whose splinting need is driven by muscle coordination rather than a bulging rectocele, it can eliminate the problem entirely.
Pessaries and Vaginal Support Devices
For people whose splinting is caused by a rectocele or posterior vaginal prolapse, a pessary offers a hands-free alternative. A pessary is a silicone or plastic device inserted into the vagina to support the prolapsed tissue, functioning like a continuous internal splint. Women who completed 12 months of pessary use in one study reported significant improvements in both bowel symptoms and bowel-related quality of life.
10PubMed. The impact of pessary use on bowel symptoms: one-year outcomesA systematic review looking specifically at support devices for posterior prolapse and perineal descent found significant improvements in stool evacuation scores across multiple pessary studies.
11PubMed. Posterior compartment prolapse and perineal descent: systematic review of available support devicesA vaginal stent is a related but different device, more like a firm insert that holds the posterior vaginal wall in place. One study found that a vaginal stent reduced straining intensity, shortened straining time, decreased laxative use, and relieved the sensation of incomplete emptying. It also increased rectal pressure and shortened balloon expulsion time, suggesting it was mechanically doing what manual splinting does but without requiring your hand.
12PubMed. Improvement in Outlet Obstructive Constipation Symptoms After Vaginal Stent Treatment for RectocelePessaries do need to be fitted by a clinician and periodically removed for cleaning. Some people wear them continuously, while others insert them only before bowel movements. The appeal is obvious: if you are splinting with your fingers every day, a device that does the same thing passively is more convenient and arguably more hygienic.
When Surgery Becomes the Conversation
Surgery is not the first-line treatment for obstructed defecation, but it becomes relevant when conservative measures (fiber, posture changes, splinting, pessaries, biofeedback) have been tried and the symptoms are significantly affecting quality of life. A systematic review of surgical options found that native-tissue transvaginal rectocele repair and site-specific posterior repairs both improved prolapse stage and symptoms of obstructed defecation. The transvaginal approach performed better than transanal repair for both anatomical correction and symptom relief, though it carried a higher rate of painful intercourse afterward.
13PubMed. Surgical interventions for posterior compartment prolapse and obstructed defecation symptoms: a systematic review with clinical practice recommendationsA separate study looking at outcomes one year after prolapse surgery found that bowel symptoms were significantly improved on average, and the development of new bothersome bowel symptoms after surgery was uncommon, affecting about 11% of patients. Achieving good vaginal support after the procedure was specifically associated with reduced risk of ongoing straining and incomplete emptying.
14American Journal of Obstetrics and Gynecology. Bowel symptoms 1 year after surgery for prolapse: further analysis of a randomized trial of rectocele repairThe important caveat is that not all surgical approaches are equal for bowel symptoms. The same systematic review noted that one type of abdominal procedure (sacrocolpoperineopexy) improved the prolapse itself but actually worsened defecatory symptoms. This underscores why the choice of surgical technique matters and why a surgeon experienced with pelvic floor reconstruction should be involved in the decision.

Almost all of the research on splinting involves women, because the anatomy that makes splinting possible and necessary, the shared wall between the vagina and rectum, is a female anatomical feature. Men do not get rectoceles in the same way, because there is no vaginal canal for the rectum to bulge into. That said, men absolutely experience obstructed defecation, dyssynergic defecation, and chronic constipation. The approaches they use tend to be different: perineal pressure, posture changes, stool softeners, and biofeedback. A man who finds himself pressing on his perineum to help evacuate is doing a form of splinting, though the term is rarely used in that context.
Dyssynergic defecation, the coordination problem described earlier, occurs in both men and women. One study using pressure-testing found that sex was a significant predictor of dyssynergic defecation, with women at higher odds, but the condition is by no means exclusive to women.

Splinting is one of those health topics that exists in a strange gap between extremely common and almost never discussed. Clinicians who specialize in pelvic floor disorders recognize it instantly and consider it a legitimate self-management technique. But many primary care doctors never ask about it, and many patients never bring it up, either because they do not have the vocabulary or because the topic feels too embarrassing. The result is that a lot of people splint for years without knowing that their underlying condition has a name, that devices exist to do the job hands-free, or that treatments like biofeedback could address the root cause. If you have been pressing on your vagina or perineum to have a bowel movement and wondering whether that is normal, the answer is that it is both normal and a signal worth paying attention to. Mention it to your doctor or, better yet, seek out a pelvic floor specialist who will know exactly what you are describing and can walk you through your options.
