Muscle contraction exercise for low back pain.
Azzam Alarab, Ratib Abu Shameh, Muntaser S Ahmad
PMID 37584053WHAT IT FOUND
Both isometric and isotonic core exercises, given alongside TENS and infrared heat, significantly reduced pain and disability in adults with non-specific low back pain.
The two exercise types were equally effective, so choice can depend on patient preference or tolerance.
Key findings
01Both exercise groups showed significant within-group improvements in pain, disability, and endurance scores after four weeks of treatment.
02There was no statistically significant difference between the isometric and isotonic groups for any outcome measure, indicating equal effectiveness.
03Pain scores dropped significantly in both groups, from an average of 6.67 to 3.0 in the isometric group and 5.9 to 4.6 in the isotonic group.

What it does not show
The sample size was small (30 participants analysed), which limits the generalisability of the findings. All participants received the same baseline treatment (TENS and infrared heat), so the study cannot determine if the exercise alone was responsible for the improvements or if the combination was necessary. The study did not include a control group receiving no treatment or sham treatment, so it cannot rule out natural recovery or placebo effects. Follow-up was only immediate post-intervention (four weeks), so long-term maintenance of gains is unknown.
Declared interests
The authors declared no conflicts of interest. The study was self-funded by the authors.
The easy way to misread this
Do not conclude that exercise alone caused the improvements. All participants received TENS and infrared heat alongside the exercises, so the specific contribution of the exercise type cannot be separated from the effect of the modalities.
