Effect of unilateral exercises on low back pain in an urban driver.
Won-Gyu Yoo
PMID 27942161WHAT IT FOUND
A taxi driver's left-sided back pain dropped from severe to mild after two ten-day exercise sessions.
Unilateral exercises targeting pelvic alignment reduced pain scores and corrected movement asymmetries, though this reflects one person's response.
Key findings
01The subject's visual analog scale score for back pain decreased from 7 to 3 after two ten-day exercise sessions.
02After the second session, the anterior pelvic tilt angles on the right and left sides were 9° and 10°, respectively, compared to 2° and 8° initially.
03Lumbar rotation movement during flexion was observed after the first session but not after the second session.

What it does not show
This is a case report involving only one participant, so the findings cannot be generalized to other patients. There was no control group or comparison intervention, so it is impossible to know if the improvement was due to the specific exercises, natural recovery, or placebo effect. The study did not measure long-term outcomes, so it is unknown if the pain reduction persisted after the intervention ended. The subjective nature of pain reporting and the potential for observer bias in measuring angles limit the certainty of the results.
The easy way to misread this
Do not interpret the reduction in pain scores as evidence that unilateral exercises are effective for low back pain in drivers. This is a single case report with no control group, and the improvement may reflect natural history or placebo effects rather than the specific intervention.
