Federal University of Paraíba30 enrolled

Overview

To analyze the effectiveness of mat Pilates compared to no intervention in individuals with chronic nonspecific low back pain.

There is evidence that exercises based on the Pilates method reduce pain in chronic nonspecific low back pain (CNLBP). However, is noticed the lack of studies that compare the effectiveness of mat Pilates to no intervention in the treatment of individual with CNLBP. Therefore, the main objective of the study is to analyze the effectiveness of mat Pilates compared to no intervention in patients with chronic nonspecific low back pain. It is a randomized controlled trial with two arms and double blinded (caregiver, assessor and outcome assessor), composed of 30 patients, aged between 18- 65 years (±22,47) of both sexes, diagnosed with chronic non-specific low back pain persisting for more than three months and pain intensity greater than 3 points in the Pain Numerical Rating Scale. The participants were randomly divided into two groups: Pilates Group (n = 15), intervention based on mat Pilates exercises, and Control Group (n =15) with no intervention. The mat Pilates group performed 16 sessions, twice a week in 60-minute duration each throughout eight weeks, whereas the control group participants kept usual cares until the end of the intervention. Both groups were evaluated before and after the program by a researcher who was unaware of the patients' allocation. The primary assessed outcomes: pain intensity (Pain numerical rating scale, and McGill questionnaire), quality of life (SF-36), and disability (Oswestry Low Back Pain Disability Questionnaire). In addition, the strength and muscle activation of transverse abdominal as secondary outcome assessed through the Stabilizer Pressure Biofeedback Unit test. As a result, the study infers that mat Pilates exercises have significantly improved all the evaluated outcomes. Thus, supporting clinical decisions for the treatment of chronic nonspecific low back pain.

The Pilates group program (PG) was composed of 16 sessions, 2x per week, 60 minute session each for 8 weeks. The intervention was based on 20 out of the 34 original mat exercises proposed by the Pilates method, classified into basic, intermediate or advanced levels divided into 4 cycles of 5 exercises each. The exercises were performed during two series of 10 repetitions respecting the patients skills.

Outcomes

Primary Outcomes

Questionnaire on Pain Intensity

The pain intensity was evaluated using an 11-point pain numerical rating scale.

Time frame: 8 weeks

Secondary Outcomes

Questionnaire on Quality of Life

The quality of life assessment was measured through the SF-36 questionnaire.

Time frame: 8 weeks

Questionnaire on Disability

The index of disability was assessed trough the 2.0 version of the Oswestry questionnaire, which is a specific questionnaire to evaluate levels of disability in people who suffer with low back pain.

Time frame: 8 weeks

Questionnaire on Pain Describers

The pain describers were evaluated through the MCGill questionnaire.

Time frame: 8 weeks
