Clinical Evidence Library

The Research Behind Every Protocol

Every Pilates Protocols programme is built on documented clinical research and published clinical guidelines. This library contains the 19 peer-reviewed studies, RCTs, Cochrane reviews, and clinical practice guidelines (NICE, ACOG, AAOS, APTA, SOSORT) that inform the exercise selection, dosage, and contraindications across the catalogue.

Curated by Sophie Mercer, PMA-certified clinical Pilates instructor. Last reviewed: 21 May 2026.

How this library is used. When a protocol references a specific statistic ("Pilates reduces low back pain by up to 72%") or guideline ("NICE recommends Pilates as first-line"), the source is listed here. When new research is published that affects a protocol, the protocol is updated and the citation is added. Where a condition has known contraindications, the supporting guideline is cited in this library and reflected in the protocol's contraindication list.

Lower Back Pain & Chronic Spinal Pain

Pilates is recommended by NICE (the UK National Institute for Health and Care Excellence) as part of a group exercise programme for non-specific low back pain. A growing body of RCTs supports its use as first-line conservative management.

  1. Asik HK, et al. (2025)

    Effect of Clinical Pilates on Pain, Disability, and Quality of Life in Chronic Low Back Pain: A Randomised Controlled Trial

    Journal of Bodywork and Movement Therapies

    Key finding: An 8-week clinical Pilates programme produced up to a 72% reduction in pain intensity (VAS) and significant improvements in Oswestry Disability Index scores compared with usual care. Effects were maintained at 12-week follow-up.

  2. National Institute for Health and Care Excellence (2016 (updated))

    NICE Guideline NG59: Low Back Pain and Sciatica in Over 16s — Assessment and Management

    NICE Clinical Guideline

    Key finding: Recommends a group exercise programme (biomechanical, aerobic, mind-body, or a combination — explicitly including Pilates) as first-line treatment for non-specific low back pain, ahead of routine pharmacological intervention.

  3. Yamato TP, Maher CG, Saragiotto BT, et al. (2015)

    Pilates for low back pain (Cochrane Review)

    Cochrane Database of Systematic Reviews

    Key finding: Concluded that Pilates is more effective than minimal intervention for short- and intermediate-term pain and disability in chronic low back pain, with effects comparable to other forms of exercise.

Sciatica, Disc-Related & Nerve Pain

Conservative management with graded exercise, neural mobilisation, and core stabilisation is the recommended first-line treatment for non-emergency sciatica and lumbar disc-related pain.

  1. Ellis RF, Hing WA (2008)

    Neural mobilization: A systematic review of randomized controlled trials with an analysis of therapeutic efficacy

    Journal of Manual & Manipulative Therapy

    Key finding: Provides preliminary evidence that neural mobilisation (used throughout the Sciatica Relief and Herniated Disc Recovery protocols) is effective in reducing pain and improving function in patients with neural pain.

  2. Fernández-Carnero J, et al. (2018)

    Neurodynamic mobilisation and foraminal herniated lumbar disks

    Spine

    Key finding: Neurodynamic mobilisation combined with motor control exercise produced significantly greater reductions in pain and disability for patients with disc-related radicular pain than motor control exercise alone.

  3. Natour J, Cazotti LDA, Ribeiro LH, et al. (2015)

    Pilates improves pain, function and quality of life in patients with chronic low back pain due to disc disease

    Clinical Rehabilitation

    Key finding: RCT of 60 patients with disc-related chronic low back pain: 90 days of Pilates added to NSAIDs produced significantly greater improvement in pain (VAS), function (Roland-Morris), and quality of life (SF-36) than NSAIDs alone.

Frozen Shoulder & Shoulder Impingement

Graded exercise that combines scapular stabilisation, glenohumeral mobility, and rotator cuff strengthening is the consensus first-line conservative treatment for adhesive capsulitis and subacromial pain.

  1. Kelley MJ, Shaffer MA, Kuhn JE, et al. (2013 (updated))

    Shoulder Pain and Mobility Deficits: Adhesive Capsulitis — Clinical Practice Guidelines

    Journal of Orthopaedic & Sports Physical Therapy

    Key finding: APTA clinical practice guideline recommends a progressive home exercise programme — including stretching, mobility, and scapular stabilisation — as the foundation of frozen shoulder management. The Frozen Shoulder Recovery protocol mirrors this staged approach.

  2. Diercks R, Bron C, Dorrestijn O, et al. (2014)

    Guideline for diagnosis and treatment of subacromial pain syndrome

    Acta Orthopaedica

    Key finding: Multidisciplinary consensus guideline: structured exercise therapy is more effective than corticosteroid injection at 6 months for shoulder impingement / subacromial pain syndrome.

Post-Surgical Recovery (Hip & Knee Replacement)

After joint replacement, structured progressive exercise focused on mobility, neuromuscular control, and gait restoration is the standard of care once the surgical site is cleared.

  1. American Academy of Orthopaedic Surgeons (2014)

    AAOS Clinical Practice Guideline: Surgical Management of Osteoarthritis of the Knee

    AAOS

    Key finding: Recommends structured post-operative rehabilitation including range-of-motion, strengthening, and functional retraining following knee arthroplasty. Pilates-based approaches align with the prescribed exercise classes.

  2. Okamoto T, et al. (2019)

    Pilates Exercise for Hip Pain Caused by Femoroacetabular Impingement

    Journal of Sport Rehabilitation

    Key finding: Pilates-based exercise programmes are effective in restoring hip mobility, gluteal strength, and pain-free range of motion in post-surgical and pre-surgical hip populations.

Women's Health: Pregnancy, Postpartum & Pelvic Floor

Pilates-based programming is widely used in pre and postnatal rehabilitation for pelvic floor recovery, diastasis recti management, and safe return to exercise.

  1. American College of Obstetricians and Gynecologists (2020)

    Physical Activity and Exercise During Pregnancy and the Postpartum Period (Committee Opinion No. 804)

    Obstetrics & Gynecology

    Key finding: ACOG explicitly endorses Pilates as a safe, beneficial form of exercise during uncomplicated pregnancy and recommends pelvic floor muscle training in the postpartum period.

  2. Dumoulin C, Cacciari LP, Hay-Smith EJC (2018)

    Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

    Cochrane Database of Systematic Reviews

    Key finding: High-quality evidence that supervised pelvic floor muscle training (a core component of the Pelvic Floor Strengthening protocol) reduces urinary incontinence and improves quality of life in women.
