Randomized Controlled Trial Multicenter Study
Effectiveness of an extension-oriented treatment approach in a subgroup of subjects with low back pain: a randomized clinical trial.
The purpose of this multicenter randomized clinical trial was to examine the effectiveness of an extension-oriented treatment approach (EOTA) in a subgroup of subjects with low back pain (LBP) who were hypothesized to benefit from the treatment compared with similar subjects who received a lumbar spine strengthening exercise program. ⋯ An EOTA was more effective than trunk strengthening exercise in a subgroup of subjects hypothesized to benefit from this treatment approach. Additional research is needed to explore whether an EOTA may benefit other subgroups of patients.
