To determine the absolute and relative reliability of intra-observer and interobserver

measurements of postural balance using the One Leg Stand Test in patients with low back pain.

Patients and methods: Forty-eight patients with chronic low back pain advised to do exercise were

: Forty-eight patients with chronic low back pain advised to do exercise were

included. A test protocol was established based on review of the literature and a pilot test. Patients

were timed for their ability to stand on one leg with their eyes open and with eyes closed. After a 20-

min break, the procedure was repeated to check for reproducibility.

Results: Eyes open: a ceiling effect was seen as more than 48% of patients were able to stand for

: Eyes open: a ceiling effect was seen as more than 48% of patients were able to stand for

the maximum time, and no further analysis was done. Eyes closed: intra-observer reliability was

tested in 21 patients; absolute reliability showed a standard error of the measurement (SEM) of

2.48 s and a minimal detectable change (MDC) of 6.88. The relative reliability was acceptable with

an intra class correlation coefficient (ICC) of 0.86. Interobserver reliability was tested in 27 patients;

absolute reliability showed a SEM of 1.42 s and a MDC of 3.95. The relative reliability was

acceptable with an ICC of 0.91.

Conclusions: The One Leg Stand Test can be used to test postural balance in patients with chronic

The One Leg Stand Test can be used to test postural balance in patients with chronic

low back pain, as the reliability of the test was acceptable.
