Perifit Pelvic Floor Trainer: Biofeedback Kegel Device with Gamified App

Roughly one in three women will experience pelvic floor dysfunction in her lifetime. The treatment is deceptively simple: strengthen the muscles through targeted exercise. The challenge is that most women perform Kegel exercises incorrectly, with no way to know whether they are engaging the right muscles.

Pelvic floor dysfunction is one of the most common and least discussed women’s health conditions. Stress urinary incontinence (involuntary leakage during coughing, sneezing, or exercise), urge incontinence, pelvic organ prolapse, and postpartum pelvic floor weakness affect an estimated 25 to 50% of women at some point in their lives. The prevalence increases with age, vaginal delivery, obesity, and chronic straining. Despite its ubiquity, pelvic floor dysfunction remains under-diagnosed and under-treated, in part because the primary intervention, pelvic floor muscle training (PFMT), suffers from a fundamental compliance and technique problem: most women who attempt Kegel exercises either engage the wrong muscles (abdominals, gluteals, or adductors instead of the pelvic floor) or perform contractions with insufficient intensity and duration. Without biofeedback, there is no way to confirm correct engagement. The Perifit Pelvic Floor Trainer addresses this gap by providing real-time biofeedback through a connected intravaginal sensor, gamifying the exercise experience to improve both technique and adherence.

What Is the Perifit Pelvic Floor Trainer?

The Perifit is an intravaginal biofeedback device consisting of a medical-grade silicone sensor that measures pelvic floor muscle contractions in real time. The sensor connects via Bluetooth to a smartphone app that translates muscle activity into interactive games: the user controls an on-screen character by contracting and relaxing her pelvic floor muscles. Correct contractions make the character fly upward; relaxation allows it to descend. This gamified interface provides immediate visual feedback on contraction strength, duration, and relaxation quality.

The app includes structured training programs of varying difficulty, tracks progress metrics (maximum contraction strength, endurance, speed, relaxation time), and adjusts exercise difficulty as the user’s pelvic floor strength improves. Training sessions typically last 5 to 10 minutes and are recommended three to five times per week.

Perifit is priced at approximately $99 to $149 depending on the model (Perifit and Perifit+, with the Plus version offering additional sensors and features). The basic app is free with the device; no subscription is required for core training features. The device is FDA registered and HSA/FSA eligible. Perifit is designed for postpartum recovery, stress incontinence management, pelvic floor strengthening, and general pelvic health maintenance.

The Science Behind Pelvic Floor Training and Biofeedback

Pelvic floor muscle training (PFMT) is the first-line treatment for stress urinary incontinence recommended by virtually every major urogynecology and physiotherapy guideline worldwide. The evidence base is substantial. A 2018 Cochrane systematic review of PFMT for urinary incontinence, analyzing 31 trials involving 1,817 women, concluded that women who performed PFMT were significantly more likely to report cure or improvement of incontinence compared to controls. The review found that supervised, intensive PFMT programs produced better outcomes than unsupervised home-based exercise.

The supervision finding is critical context for understanding biofeedback devices. The superiority of supervised PFMT is attributed to two factors: correct muscle identification (a trained physiotherapist can palpate and confirm correct engagement) and progressive overload (the therapist guides increasing exercise intensity over time). In the absence of supervision, an estimated 30 to 50% of women perform Kegel exercises incorrectly, engaging abdominal, gluteal, or hip adductor muscles instead of (or in addition to) the pelvic floor. Without feedback, these women believe they are training correctly while making little to no progress.

Biofeedback addresses this gap by providing an external signal (visual, auditory, or tactile) that confirms correct pelvic floor engagement. Intravaginal pressure sensors measure the force generated during pelvic floor contraction, and when this measurement is displayed in real time, the user can learn to selectively activate the pelvic floor while keeping surrounding muscles relaxed. Research on biofeedback-assisted PFMT has generally shown that biofeedback improves initial muscle identification accuracy and may improve short-term outcomes, though the evidence for long-term superiority over well-taught PFMT without biofeedback is less conclusive.

Gamification addresses the second major challenge: adherence. PFMT is effective only with consistent practice over weeks to months. Dropout rates in home-based PFMT programs are high, typically 50% or more within the first few months. By converting repetitive pelvic floor contractions into interactive games with visual feedback, scoring, and progressive challenges, gamified biofeedback devices aim to transform a monotonous exercise into an engaging activity that users are motivated to repeat.

That is the science. Here is how the Perifit applies it.

What the Perifit Does Well

Perifit’s gamified biofeedback interface is its most distinctive feature and its primary clinical advantage. By translating pelvic floor contraction data into game mechanics, Perifit provides three things simultaneously: confirmation of correct muscle engagement (the game responds only to genuine pelvic floor contractions), real-time intensity feedback (stronger contractions produce more dramatic game responses), and engagement that motivates consistent practice. This combination addresses both the technique and the adherence barriers that limit the effectiveness of unsupervised PFMT.

The structured training programs provide progressive overload without requiring a physiotherapist to design the program. As the user’s pelvic floor strength improves, the app increases exercise difficulty: longer hold times, faster contraction/relaxation cycles, and more challenging game levels. This automated progression mimics the periodization that a trained therapist would provide, adapted to the individual’s measured capabilities.

The quantified progress tracking gives users objective evidence that their training is producing results. Seeing that maximum contraction force has increased from 40% to 65% over six weeks provides motivation that subjective perception (“I think my bladder control is better”) cannot match. This data can also be shared with healthcare providers to document treatment progress.

The medical-grade silicone construction is body-safe, hypoallergenic, and easy to clean. The wireless Bluetooth connection means no wires or external equipment during use. Sessions are short (5 to 10 minutes), private, and require no gym, equipment, or special space beyond the smartphone.

Pricing, Access, and Practical Realities

Perifit retails at approximately $99 to $149 depending on the model. The basic model provides core biofeedback and gamified training. The Perifit+ adds enhanced sensors and additional tracking capabilities. No subscription is required for core training features; the companion app is free with the device.

Total cost of ownership is the one-time hardware purchase price. There are no consumables, replacement parts, or recurring fees. Over a year of use, Perifit costs roughly $0.27 to $0.41 per day, significantly less than pelvic floor physiotherapy sessions (typically $100 to $250 per visit).

The device is FDA registered as a general wellness device and is HSA/FSA eligible. It is not FDA cleared for the treatment of urinary incontinence or any specific medical condition. This means Perifit cannot make medical treatment claims, though the underlying evidence for PFMT as a treatment for incontinence is well established in the clinical literature.

Practical considerations: the device requires insertion, which may be uncomfortable or unfamiliar for some users. The sensor should be cleaned before and after each use per the manufacturer’s hygiene instructions. The device is not recommended for use during pregnancy (without healthcare provider approval), during active pelvic infections, or within the first 6 to 8 weeks postpartum before clearance from an obstetric provider.

Who the Perifit Is Best For

Perifit is ideal for postpartum women who want to rebuild pelvic floor strength after vaginal delivery. The combination of biofeedback (ensuring correct muscle engagement during a period when pelvic floor awareness may be diminished) and gamification (providing motivation during the demanding early months of parenthood) makes it well-suited to this population.

Women experiencing mild to moderate stress urinary incontinence who want to try conservative treatment before considering surgical options will find Perifit a practical and affordable first-line approach. Women approaching or in perimenopause, when declining estrogen levels contribute to pelvic floor tissue changes and increased incontinence risk, benefit from proactive pelvic floor strengthening.

Women with severe pelvic organ prolapse, complex pelvic floor dysfunction, or pelvic pain syndromes should seek evaluation from a pelvic floor physiotherapist or urogynecologist rather than self-treating with a consumer device. Perifit is appropriate for strengthening, not for diagnosing or managing complex pelvic floor pathology. Women who are uncomfortable with intravaginal devices should consider external biofeedback options or physiotherapy-guided training.

How the Perifit Compares

The Elvie Trainer ($199) is the primary premium competitor, offering similar intravaginal biofeedback with a gamified app interface. The Elvie Trainer benefits from the Elvie brand’s strong recognition in women’s health technology and a polished app experience. At roughly twice the price of the base Perifit, the Elvie Trainer offers comparable core functionality with a different sensor design and game mechanics. The choice between them often comes down to app preference, sensor comfort, and budget.

Pelvic floor physiotherapy (typically $100 to $250 per session, often covered by insurance) provides the gold standard for pelvic floor assessment and training. A trained physiotherapist can perform manual palpation to confirm correct engagement, identify specific muscle weakness patterns, and design individualized rehabilitation programs. For complex cases, physiotherapy is superior to any consumer device. For straightforward strengthening and maintenance, Perifit provides a cost-effective complement or alternative to ongoing physiotherapy sessions.

Non-connected Kegel exercisers (weighted vaginal cones, spring-resistance devices) cost $15 to $40 and provide passive resistance without biofeedback. These devices strengthen the pelvic floor through weight-bearing exercise but do not confirm correct muscle engagement or provide progress tracking. They are cheaper but less effective at correcting technique errors.

Limitations and Open Questions

Biofeedback-assisted PFMT has demonstrated clear benefits for initial muscle identification and short-term strength gains. However, the long-term evidence comparing consumer biofeedback devices to well-taught, supervised PFMT shows less clear superiority. A woman who learns correct technique from a physiotherapist and practices consistently may achieve equivalent outcomes without a biofeedback device. Perifit’s value is greatest for women who lack access to pelvic floor physiotherapy or who need the gamification to maintain adherence.

The device measures overall vaginal pressure, which includes contributions from the pelvic floor, abdominal muscles, and vaginal wall tone. While the app’s algorithms attempt to isolate pelvic floor specific contractions, the sensor cannot definitively distinguish between a pure pelvic floor contraction and a combined contraction that includes abdominal bearing down. Users who consistently use incorrect technique may still register some signal on the sensor, though the games are designed to reward the contraction patterns most consistent with isolated pelvic floor engagement.

Perifit is not a diagnostic tool. It cannot assess the degree of pelvic organ prolapse, identify specific muscle injury patterns, or diagnose the cause of incontinence. Women with persistent symptoms despite PFMT should seek clinical evaluation rather than assuming they need more training.

The intravaginal form factor limits the user population. Some women find intravaginal devices uncomfortable, culturally inappropriate, or medically contraindicated. External sensor alternatives exist in clinical settings but are not available in the consumer biofeedback market at comparable price points.

What This Means for Your Health

Pelvic floor health is a foundational component of physical function that is dramatically underserved by mainstream health technology and health communication. Within Healthcare Discovery‘s Five Pillars framework, pelvic floor strength connects directly to movement (core stability, exercise capacity, and incontinence-free physical activity), mindset (the confidence to exercise, travel, and socialize without fear of leakage), and the broader health practices that sustain long-term physical independence.

The longevity context is straightforward. Pelvic floor dysfunction worsens with age, contributing to social isolation, reduced physical activity, and decreased quality of life in older adults. Urinary incontinence is one of the leading reasons for nursing home admission. Building and maintaining pelvic floor strength through targeted exercise is a proactive intervention that supports physical independence across the lifespan.

Perifit makes this intervention accessible, measurable, and, through gamification, genuinely engaging. At $99 to $149 with no ongoing cost, it is less expensive than a single physiotherapy session and provides unlimited training sessions at home. For the one in three women who will experience pelvic floor dysfunction, a biofeedback device that teaches correct technique and motivates consistent practice addresses a health need that has been underserved for far too long.

Frequently Asked Questions
