Effects of the Pilates Method Versus Home Exercise in Individuals With Chronic Non-specific Back Pain (COmEBACK)

Effectiveness and Cost-effectiveness of the Pilates Method Versus Home-based Exercises in Individuals With Chronic Non-specific Low Back Pain: a Randomized Controlled Trial

The aim is to compare the effectiveness and cost-effectiveness of a Pilates program versus home-based exercises in individuals with chronic non-specific low back pain. This is a randomized controlled trial with economic evaluation. Participants will be sequentially enrolled and randomly allocated into two groups: 1) Pilates: Mat Pilates sessions, supervised by a physiotherapist (2x/week for 6 weeks); 2) Home-Based Exercise: face-to-face familiarization (two sessions), supervised by another physiotherapist. After familiarization, the exercises will be prescribed using a booklet containing descriptions of sets/repetitions, as well as guidelines and precautions, to be performed during 6 weeks (2x/week) and monitored in a diary. Participants will be supervised by the physiotherapist (telephone/text messaging). Participants will be evaluated in three different moments: 1) Baseline (pre-intervention); 2) At the end of the intervention (post-intervention, 6 weeks); and 3) After six months follow-up (from post-intervention). Primary outcomes: pain intensity and disability. Secondary outcomes: perception of recovery, postural balance, and quality of life. Concurrently, a cost-effectiveness study will be conducted comparing the Pilates vs Home-Based Exercise, from the perspectives of public healthcare and society. In the first perspective, only costs incurred by the public healthcare system will be included (direct costs related to consultations, medications, tests, hospitalizations, and professional fees). In the second perspective, private health care expenses, costs incurred by patients (transportation and support by caregivers, when applicable), as well as indirect costs (missed workdays and loss of productivity) will be included. The incremental cost-effectiveness ratios for the primary outcomes and cost-utility ratios will be calculated for both perspectives. The cost-utility ratio will express the incremental costs per quality-adjusted life year (QALY). In addition, the absolute and incremental net monetary benefit will be calculated. Sensitivity analyses will be conducted. Data normality assumptions will be evaluated using the Shapiro Wilk test. If confirmed, a mixed model will be used, for the comparisons between groups and moments. It is hypothesized that the Pilates will be more cost-effective compared to the home-based exercise program.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Pilates Method; Mat Pilates Program, 2x/week, for 6 weeks, supervised by a Physiotherapist. Sessions will last forty five min, with 4 individuals per session. On average, 10 to 15 exercises will be performed per session, with repetitions ranging from 10 to 20 times, according subject's limitations. If necessary, the exercises will be adapted individually for the three levels of difficulty: basic, intermediate and advanced. Progress will be dependent on the absence of postural compensations when performing the repetitions of the exercises.	Other: Pilates; The protocol will be composed by the following exercises, structured in each session according to progression, difficulty and focus (respiration, stability, muscle strength and joint mobility): Arm Arcs, Bent Knee Opening, Sidelying, Dead Bug, Femur Arcs, Quadruped Series, Single Leg Stretch, Prone Press Up, Sidekick (Front to Back 1 e 2), Leg Pull Front, Mermaid, Spine Stretch, The Hundred, Pelvic Clock, Bridging, Stanging Roll Down, Swan, Saw, Dart, Swimming, Book Opening. .; Other Names: Therapeutic exercise
ACTIVE_COMPARATOR: Home Exercise Prescription; Composed by two familiarization sessions, supervised by a Physiotherapist. The protocol include postural reeducation exercises, stretching and muscle strengthening, stabilization and mobilization of the spine. Subsequently, participants will receive an educational booklet containing information on low back pain, anatomy of the spine and its relation to the muscular chain, care during daily life activities and the importance of regular physical exercises. Also, it will include a booklet with the prescription of therapeutic home exercises to be performed during the next 6 weeks. It will be recommended that the participants perform the exercises 2x/week. Participants will also be contacted weekly by email and/or telephone, for remote supervision and for checking the prescribed exercises.	Other: Home Exercises; The protocol will be divided into 3 phases, each one composed by the following exercises and structured according to difficulty progression and focus (postural reeducation, muscle strength, balance, joint flexibility): Muscle strength exercises composed by abdominal exercises; back extension exercises; gluteus maximus exercises. Stretching exercises for the lower back, pelvis, iliopsoas muscle, tensor fascia latae muscle).; Other Names: Therapeutic exercise

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain Intensiy	Pain Intensity measured on a Visual Analog Scale (VAS, in centimeters)	Change from Pre-Intervention (baseline) compared to Post-Intervention (6 weeks) and Follow-up (6 months)
Disability	Quebec Back Pain Disability Scale, scores ranging from 0 to 100	Change from Pre-Intervention (baseline) compared to Post-Intervention (6 weeks) and Follow-up (6 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Health status	Measure of health status by the EQ-5D-3L questionnaire, consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each of which can take one of five responses. The responses record five levels of severity (no problems/slight problems/moderate problems/severe problems/extreme problems).	Change from Pre-Intervention (baseline) compared to Post-Intervention (6 weeks) and Follow-up (6 months)
Balance	Balance Platform, variation of the platform displacement	Change from Pre-Intervention (baseline) compared to Post-Intervention (6 weeks) and Follow-up (6 months)
Perception of Recovery	Perception of Recovery measured by a Global Perceived Effect Scale (11-point scale), ranging from -5 ("much worse"), 0 ("no change"), to 5 ("completely recovered")	Change from Pre-Intervention (baseline) compared to Post-Intervention (6 weeks) and Follow-up (6 months)
