Adding trunk stretching showed no clear extra benefit for chronic low back pain
Both exercise groups improved in pain and disability, but active stretching did not clearly outperform placebo stretching when both groups also received lumbar stabilization exercises.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The trial tested whether active trunk stretching added benefit to lumbar stabilization exercises. Pain and disability improved in both groups, but no measured outcome differed significantly between them. This leaves the added value of active stretching unproven in this study. It does not establish that the approaches are equivalent or that stretching can never help.
This abstract-based summary covers a small trial with no group that avoided stabilization exercises. The abstract reports no numerical between-group effects or confidence intervals, making the range of plausible differences difficult to judge.
What researchers found
Pain intensity and functional disability
Active versus placebo stretching, both added to lumbar stabilization; assessed after 6 weeks and at 12- and 24-week follow-up.
The added component
The important comparison was active stretching against placebo stretching while keeping stabilization exercises in both groups. Improvement within each group does not answer whether stretching added anything, or isolate stabilization from other explanations for change.
Emotional changes faded
Depression and anxiety improved during the intervention, but those improvements did not continue at follow-up. This distinction matters because short-term symptom changes should not be presented as lasting emotional benefits.
