Hypothesis
The study aims to assess the test-retest reproducibility of a seated postural control test in low back pain patients.
Conclusion
The test-retest reproducibility of these postural control tests in an unstable sitting position can globally be considered as rather moderate.
Supporting Evidence
- Chronic low back pain patients have lesser postural control compared to healthy subjects.
- All Intraclass Correlation Coefficients (ICC) calculated for the force plate variables did not exceed 0.73.
- A learning effect was suggested as a reason for low test-retest reproducibility.
Takeaway
This study looked at how well we can repeat balance tests for people with back pain while sitting on a wobbly board. It found that practice helps improve the results.
Methodology
Postural control was measured using a three-dimensional motion analysis system combined with a force plate, with each subject performing four tests repeated four times.
Limitations
The study did not allow subjects to practice before the actual tests, which may have affected the reproducibility results.
Participant Demographics
16 chronic low back pain patients, 6 men and 10 women, mean age 33 years.
