PMID 40977828WHAT IT FOUND
All three exercise programs reduced pain and disability over six weeks.
Dynamic back extensions lowered pain more than McKenzie or static exercises at three weeks. Creatine kinase rose in all groups but stayed within normal limits, showing no muscle damage.
Key findings
01Pain intensity was significantly lower in the dynamic back extension group compared to both McKenzie and static groups at three weeks, but no significant differences remained between groups at six weeks.
02Creatine kinase levels increased significantly within all groups from baseline to week six, but the authors state these values remained within the normal range and did not indicate muscle damage.
03The McKenzie group had significantly lower IL-10 levels compared to the static and dynamic groups at both three and six weeks, suggesting a weaker anti-inflammatory response than the endurance exercises.

What it does not show
The study only included patients with a directional preference for extension, so the results do not apply to patients who prefer flexion or have no directional preference. There was no placebo or control group, so it is unclear how much of the improvement was due to natural recovery or the back care education all participants received. The follow-up period was only six weeks, so it is unknown if the differences in biomarkers or pain relief persist long-term. Therapists were not blinded to the treatment allocation, which may have introduced performance bias, although outcome assessors and lab analysts were blinded.
Declared interests
The authors declare no conflict of interest. The research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.
The easy way to misread this
Do not interpret the significant rise in creatine kinase as evidence of muscle damage or harm from the exercises. The study states these levels remained within the normal range, indicating physiological muscle activity rather than injury.
