Low back pain (LBP) is an important health problem in all developed
countries and is associated with high levels of disability.
Evidence-based
clinical practice guidelines usually recommend different physical therapy
interventions to manage this condition. However, those interventions usually
result in small to moderate clinical effects. Recent studies suggest that
interventions based on subgroup classifications may improve the effect sizes
compared with rehabilitation programs where the same interventions were applied
to all patients. OBJECTIVE: This study will investigate the efficacy of treatment
based on a Movement System Impairment (MSI)-based classification model for
patients with chronic LBP compared with general exercise. The primary outcomes
will be pain intensity and disability at 2 months after randomization. DESIGN:
The study is a 2-arm, prospectively registered, randomized controlled trial with
a blinded assessor. SETTING: The study setting will be a university physical
therapy clinic in Brazil. PARTICIPANTS: A total of 148 individuals with chronic
LBP will participate in the study. INTERVENTION: Included individuals will be
randomly allocated to participate in an 8-week treatment program based on the
MSI-based classification or a general exercise program of stretching and
strengthening exercises. MEASUREMENTS: Pain intensity, disability, and global
impression of recovery will be assessed by a blinded assessor at baseline and at
follow-up appointments after treatment (2 months) and 4 and 6 months after randomization. LIMITATIONS: Therapists will not be blinded. CONCLUSIONS:
The results of this study may contribute to a better understanding of the efficacy of
treatments based on classification of participants with chronic LBP into
subgroups.
