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: 1 October 2026.

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.
-
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.
-
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.
-
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.
Applied in: Lower Back Pain Recovery
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.
-
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.
-
Effects of Adding a Neurodynamic Mobilization to Motor Control Training in Patients With Lumbar Radiculopathy Due to Disc Herniation: A Randomized Clinical Trial
American Journal of Physical Medicine & Rehabilitation
Key finding: Small RCT (n=32) in disc-related lumbar radiculopathy: adding neurodynamic mobilisation to motor control exercise improved neuropathic symptoms and straight-leg-raise range more than motor control alone, but did not further reduce pain or disability. Supports neural gliding as an adjunct to, not a replacement for, stability work.
-
Pilates improves pain, function and quality of life in patients with chronic low back pain: a randomized controlled trial
Clinical Rehabilitation
Key finding: RCT of 60 patients with chronic non-specific low back pain: 90 days of Pilates added to NSAID use produced significantly greater improvement in pain (VAS), function (Roland-Morris) and quality of life (SF-36) than NSAIDs alone. Participants were not selected for disc disease, so the result applies to chronic low back pain generally.
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.
-
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.
Applied in: Frozen Shoulder Recovery -
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.
-
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.
Applied in: Knee Replacement Recovery -
Exercise for osteoarthritis of the hip (Cochrane Review)
Cochrane Database of Systematic Reviews
Key finding: Cochrane review of 10 RCTs (549 participants): land-based therapeutic exercise reduces pain and improves physical function in hip osteoarthritis, with benefits sustained for at least 3–6 months after treatment ends. Progressive hip strengthening and mobility work is the basis of the Hip Replacement Recovery protocol.
Applied in: Hip Replacement Recovery
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.
-
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.
-
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.
-
Prevalence and risk factors of diastasis recti abdominis from late pregnancy to 6 months postpartum
Manual Therapy
Key finding: Diastasis recti is prevalent through 6 months postpartum and benefits from targeted deep core programming rather than generic abdominal exercise — informing the postpartum core sequencing used in the protocol.
Applied in: Postpartum Recovery
Osteoporosis, Scoliosis & Bone Health
Targeted exercise for bone health emphasises spinal extension, balance training, and progressive loading — with specific contraindications around forward flexion and axial rotation in osteoporotic spines.
-
Stronger Back Muscles Reduce the Incidence of Vertebral Fractures
Bone
Key finding: A 2-year back-extensor strengthening programme produced a 2.7-fold reduction in vertebral fracture incidence at 10-year follow-up in postmenopausal women — supporting the spinal extension focus in the Osteoporosis protocol.
-
Physical Activity, Bone Health, and Osteoporosis
Journal of Aging and Physical Activity
Key finding: Confirms that resistance and weight-bearing exercise are core components of osteoporosis management, with explicit caution against loaded forward flexion — reflected in the contraindications listed in the protocol.
Applied in: Osteoporosis Protocol -
SOSORT Guidelines: Orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth
Scoliosis and Spinal Disorders
Key finding: International consensus guideline supporting physiotherapeutic scoliosis-specific exercises (PSSE) for management of idiopathic scoliosis. The Scoliosis Management protocol follows PSSE principles of asymmetric strengthening and three-dimensional self-correction.
Applied in: Scoliosis Management
Plantar Fasciitis, Knee Pain & Lower-Limb Conditions
Lower-limb conditions benefit from progressive loading and proximal (hip) strengthening — both core principles of the relevant Pilates Protocols.
-
High-load strength training improves outcome in patients with plantar fasciitis: A randomized controlled trial
Scandinavian Journal of Medicine & Science in Sports
Key finding: High-load slow-speed calf and intrinsic foot strengthening produced significantly greater functional improvement at 3 months than standard stretching. Informs the loading progression in the Plantar Fasciitis Relief protocol.
Applied in: Plantar Fasciitis Relief -
Proximal muscle rehabilitation is effective for patellofemoral pain: a systematic review with meta-analysis
British Journal of Sports Medicine
Key finding: Systematic review with meta-analysis: rehabilitation targeting the hip (proximal) muscles, alone or combined with quadriceps work, reduces patellofemoral pain (runner's knee) and improves function, with combined proximal-plus-quadriceps programmes performing best. Reflected in the gluteal sequencing of the Runner's Knee Pain protocol.
Stress, Anxiety & Mind-Body Outcomes
Mind-body exercise has documented effects on perceived stress, anxiety symptoms, and sleep quality independent of the cardiovascular benefits.
-
The effects of Pilates on mental health outcomes: A meta-analysis of controlled trials
Complementary Therapies in Medicine
Key finding: Meta-analysis of 8 controlled trials: Pilates produced significant reductions in symptoms of depression, anxiety, and fatigue, with a moderate-to-large effect size compared with controls.
Applied in: Stress & Anxiety Relief
