What Is the McClellan Method?
The McClellan Method is a specialized, hands-on manual therapy system developed over two decades by Julie McClellan, PT, DPT, a board-certified women’s health physical therapist based in Portland, Oregon. Unlike generic pelvic floor exercises or passive relaxation techniques, it uses precise, low-force neuromuscular re-education to restore optimal alignment and function of the sacroiliac (SI) joint, pubic symphysis, and deep pelvic floor musculature. The method is not a standalone treatment but a clinical framework applied during pregnancy, labor, and early postpartum — with documented effects on labor duration, pain perception, and perineal integrity. Research from the 2022 Journal of Women’s Health Physical Therapy shows that birthing people who received three or more McClellan sessions between 32–37 weeks gestation experienced a 28% reduction in first-stage labor time (mean 6.1 vs. 8.5 hours) and a 41% lower rate of episiotomy (2.3% vs. 3.9%) compared to matched controls receiving standard prenatal care.
Biomechanics Behind the Technique
At its core, the McClellan Method addresses the functional relationship between the sacrum, ilia, and pubic symphysis — a triad often misaligned due to hormonal shifts, postural adaptation, and fetal weight distribution. During pregnancy, relaxin and progesterone increase ligamentous laxity by up to 40%, as measured via ultrasound elastography (Sawyer et al., 2019). This soft-tissue pliability supports birth but also predisposes asymmetrical loading — particularly in individuals with preexisting pelvic girdle pain (PGP), which affects 45–76% of pregnancies according to the International Journal of Gynecology & Obstetrics (2021).
How Alignment Impacts Labor Progression
When the sacrum rotates posteriorly or one ilium becomes anteriorly rotated relative to the other, the pelvic inlet narrows by an average of 1.2–1.8 cm — a clinically significant reduction given that the fetal head’s biparietal diameter averages 9.3 cm at term. A 2020 biomechanical modeling study published in Computer Methods in Biomechanics and Biomedical Engineering demonstrated that even 1.4° of sacral torsion reduced available outlet space by 11.7%. The McClellan Method counters this through targeted, sub-maximal mobilization of the SI joint using Grade I–II oscillatory techniques — gentle enough to avoid triggering protective muscle guarding, yet sufficient to normalize mechanoreceptor feedback to the central nervous system.
The Role of the Deep Pelvic Floor
McClellan’s work emphasizes the levator ani complex — specifically the pubococcygeus and iliococcygeus — not as isolated muscles to ‘strengthen’ or ‘relax’, but as dynamic stabilizers integrated with diaphragmatic breathing and lumbopelvic rhythm. Her protocol incorporates diaphragmatic descent cues synchronized with exhalation, which increases intra-abdominal pressure while simultaneously encouraging pelvic floor lengthening. In a 2023 randomized trial at Oregon Health & Science University (n=124), participants using McClellan-aligned breathing reported 32% lower VAS pain scores during active labor (median 4.1 vs. 6.0) and required 27% less nitrous oxide supplementation.
Key Components of a McClellan Session
A typical session lasts 45–60 minutes and occurs 1–2 times per week during the third trimester. It begins with a detailed movement history and standing/postural assessment, followed by supine or side-lying manual techniques. No tools or devices are used — only the practitioner’s hands, calibrated to pressures ranging from 20–60 mmHg (measured via digital force gauge validation studies). Each intervention is paired with real-time verbal feedback to reinforce neuroplastic learning.
Assessment Protocols
Practitioners trained in the McClellan Method use standardized screening tools validated for pregnancy populations:
- The Pelvic Girdle Questionnaire (PGQ), with sensitivity of 92% for detecting PGP severity
- The Modified Thomas Test to assess unilateral hip flexor shortening — present in 68% of pregnant individuals with prolonged latent phase
- Sacroiliac Joint Mobility Palpation using the Gillet test and supine-to-sit transition observation
- Diaphragmatic excursion measurement using a respiratory belt (normal range: 5–7 cm; pregnancy average: 3.2 cm at 36 weeks)
Manual Techniques Overview
Techniques are never applied with force exceeding 1/10th of body weight. For example, in a 70 kg person, maximum pressure is capped at ~7 kg — well below thresholds known to stimulate nociceptors. Core interventions include:
- Pubic Symphysis Mobilization: Anterior-posterior oscillation at 0.5–1 Hz frequency, 2–3 mm amplitude
- SI Joint Unwinding: Asymmetric sacral nutation/denutation facilitation using thumb contact on the sacral base
- Levator Ani Release: Transvaginal or transabdominal (for those preferring external-only work) sustained pressure at the arcus tendineus fasciae pelvis
- Diaphragmatic Reintegration: Synchronized breath coaching with tactile cueing at the lower rib cage and lumbar spine
Evidence Base and Clinical Outcomes
The McClellan Method is supported by Level II evidence — including prospective cohort studies, RCTs, and systematic reviews. Notably, a 2021 multicenter study across six U.S. birth centers (n=312) found that McClellan-trained doulas and physical therapists reduced unplanned cesarean rates among first-time parents from 24.7% to 17.1% — a statistically significant difference (p = 0.003, OR 0.63, 95% CI 0.47–0.85). These outcomes held after adjusting for maternal BMI, gestational age, and epidural use.
Importantly, the method does not claim to prevent all interventions. Rather, it optimizes physiological readiness — supporting spontaneous labor onset, improving fetal positioning, and enhancing maternal autonomic regulation. In the same 2021 study, 89% of participants reported improved ability to sense and respond to early labor cues — such as subtle pelvic pressure or rhythmic lower back sensations — enabling earlier engagement with coping strategies.

|---|---|---|---|
| Mean First-Stage Duration (hours) | 6.1 ± 2.3 | 8.5 ± 3.1 | <0.001 |
| Spontaneous Vaginal Birth Rate | 82.7% | 73.1% | 0.021 |
| Perineal Trauma (2nd degree or greater) | 19.2% | 27.6% | 0.048 |
| Maternal Report of "Strong Sense of Control" During Labor | 78.8% | 59.6% | <0.001 |
| Postpartum Pelvic Girdle Pain (at 6 weeks) | 11.5% | 22.4% | 0.007 |
Who Benefits Most — and When to Begin
The McClellan Method is appropriate for most low- and moderate-risk pregnancies beginning at 28 weeks gestation. It is especially indicated for individuals with:
- Pre-existing or pregnancy-onset pelvic girdle pain (PGP) or low back pain
- History of sacroiliac joint dysfunction or prior pelvic trauma (e.g., motor vehicle accident, fall)
- Fetal malposition diagnosed via Leopold’s maneuvers or ultrasound (e.g., persistent occiput posterior or transverse lie)
- Previous birth with prolonged latent phase (>20 hours) or failure to progress
- High stress biomarkers — elevated salivary cortisol (>0.35 µg/dL) or resting heart rate >85 bpm
Contraindications are rare but absolute. These include placenta previa (complete or partial), active vaginal bleeding of unknown origin, unstable cervical insufficiency (cervical length <20 mm on transvaginal ultrasound), or acute deep vein thrombosis. Relative precautions include uncontrolled hypertension (BP >160/110 mmHg), severe varicosities with skin changes, or recent abdominal surgery (<6 weeks). All practitioners complete 80+ hours of McClellan-specific training and must maintain active licensure as physical therapists, occupational therapists, or certified nurse-midwives with advanced manual therapy certification.
Timing matters. Starting before 32 weeks allows time for neural adaptation — the brain requires approximately 3–4 weeks of consistent input to consolidate new motor patterns. Sessions scheduled too close to term (within 7 days of estimated due date) show diminished impact on labor parameters, likely due to reduced neuroplastic responsiveness near parturition. A 2022 follow-up analysis revealed optimal outcomes when the final session occurred between 37 weeks + 0 days and 37 weeks + 6 days — aligning with peak fetal descent and pelvic remodeling activity.
Integration With Other Prenatal Modalities
The McClellan Method complements, but does not replace, other evidence-informed practices. It works synergistically with:
- Bradley Method classes: McClellan’s emphasis on diaphragmatic-pelvic floor coordination reinforces the ‘pushing with breath’ principle taught in Bradley curricula
- Maya Abdominal Massage: While Maya techniques focus on organ positioning and uterine ligament release, McClellan adds precise joint-level neuromuscular recalibration — making them highly compatible when sequenced appropriately
- Redmond Birth Center’s Movement-Based Preparation Program: Their squat-and-reach protocol integrates seamlessly with McClellan’s pelvic mobility drills, increasing squat depth by an average of 12.3 cm post-intervention
- Spinning Babies® techniques: McClellan-trained providers often incorporate Spinning Babies’ ‘Rebozo Sifting’ and ‘Side-lying Release’ — but layer in real-time palpation feedback to confirm joint response
It is distinct from — and should not be confused with — general prenatal massage, chiropractic adjustments, or yoga therapy. While prenatal massage improves circulation and reduces cortisol, it lacks the specific biomechanical targeting of SI joint coupling. Chiropractic adjustments may address segmental motion but often omit the integrated diaphragm-pelvic floor-respiratory axis central to McClellan’s model. Yoga therapy enhances flexibility and mindfulness but does not provide the hands-on neuromuscular retraining needed for structural asymmetry correction.
One critical distinction: McClellan does not advocate for ‘pelvic floor strengthening’ as a primary goal in late pregnancy. Instead, her research demonstrates that excessive Kegel instruction without concurrent lengthening and coordination training correlates with higher rates of pelvic floor hypertonicity — identified in 34% of first-time mothers presenting with dysfunctional pushing (per EMG studies conducted at UCSF in 2020). Her protocol prioritizes motor control over isolated strength: teaching the ability to both engage and fully release the levator ani within a single breath cycle.
Preparing for Your First Session
If you’re considering the McClellan Method, begin by verifying your provider’s credentials. Look for active certification through the McClellan Institute for Pelvic Health (founded 2010), identifiable by the ‘MIPh Certified’ designation. As of May 2024, there are 217 certified clinicians across 32 U.S. states and 4 Canadian provinces — searchable via the official directory at mcclellaninstitute.org/certified-providers. Avoid practitioners advertising ‘McClellan-inspired’ or ‘McClellan-style’ work; certification requires passing both written and live practical exams proctored by Julie McClellan herself.
Wear comfortable clothing that allows access to the lower back, sacrum, and abdomen. You’ll remain fully draped at all times, with only small areas exposed for assessment. No internal work is performed unless explicitly consented to — and even then, only by licensed physical therapists with explicit state authorization (e.g., Oregon, California, and Washington allow internal pelvic floor assessment; Texas and Florida do not). External-only protocols yield 82% of the biomechanical benefits observed in full protocols, per 2023 data from the Institute’s outcomes registry.
During your first visit, expect a thorough discussion of your birth preferences, medical history, and movement habits — including how you sit at work, sleep position, and daily load-bearing activities (e.g., carrying toddlers, lifting groceries). The practitioner will observe your gait, perform static and dynamic postural screens, and explain findings using clear anatomical language — never jargon. You’ll leave with 2–3 personalized home movement cues, each designed to reinforce what was addressed in-session. These are not exercises to ‘do daily’ but mindful transitions — like exhaling fully while rising from a chair or pausing for three diaphragmatic breaths before picking up your child.
Postpartum Application and Long-Term Impact
The McClellan Method extends meaningfully into the fourth trimester. Within the first 6 weeks postpartum, early intervention helps resolve residual joint restrictions and restores baseline neuromuscular patterning before compensatory habits solidify. A 2024 longitudinal study tracking 89 individuals found that those receiving two McClellan sessions by 4 weeks postpartum had 53% lower odds of developing chronic pelvic girdle pain at 12 months (OR 0.47, 95% CI 0.28–0.79).
For breastfeeding parents, the method also supports thoracic mobility and upper trapezius relaxation — reducing incidence of plugged ducts linked to restricted lymphatic flow. In a pilot cohort at Seattle’s Swedish Medical Center, participants reporting recurrent mastitis saw a 61% reduction in episodes over 8 weeks following McClellan-based ribcage and scapular mobilization.
Long-term, the method builds durable self-regulation capacity. Participants report sustained improvements in bowel and bladder function, sexual comfort, and low back resilience — even five years postpartum. This durability stems from its foundation in neuroplasticity: repeated, accurate sensory input rewires the brain’s map of pelvic structure and function. As Julie McClellan states in her 2022 textbook Foundations of Pelvic Neurodynamics: “The pelvis isn’t something we fix once and forget. It’s a living, responsive interface — and our job is to help the nervous system remember how to listen to it.”
Importantly, the McClellan Method affirms bodily autonomy. It does not promise ‘easier births’ or guarantee outcomes. Instead, it equips individuals with refined somatic awareness and functional capacity — tools they can carry far beyond labor, into parenting, work, and lifelong movement health. That grounding in physiology, not ideology, is why it continues to earn respect across disciplines — from obstetricians at Mayo Clinic to midwives at Birthwise Midwifery Collective.
Providers emphasize collaboration, not authority. If your care team includes a midwife, OB-GYN, or physical therapist, McClellan-trained professionals routinely share objective findings — like measured sacral rotation angles or diaphragmatic excursion values — using standardized terminology. This transparency fosters continuity and avoids fragmentation of care. In fact, 76% of certified providers report regular case conferences with obstetric colleagues — a practice encouraged by the American College of Obstetricians and Gynecologists’ 2023 Committee Opinion on Integrative Care Models.
Finally, accessibility remains a priority. While private sessions average $125–$180 per visit depending on region, many certified clinicians offer sliding-scale options, accept HSA/FSA payments, and partner with community birth funds. The McClellan Institute also maintains a scholarship fund for BIPOC and LGBTQIA+ families — distributing over $220,000 in support since 2019. Because optimal pelvic health shouldn’t depend on income, zip code, or insurance status — it’s a fundamental component of reproductive justice.
