PMID 29950766WHAT IT FOUND
Closing the eyes made left and right one-leg standing times differ more often.
In healthy students with unequal hip internal rotation, the one-leg standing pattern matched the hip pattern more often with eyes closed.
Key findings
01With eyes closed, 93 of 101 participants had a left-right difference in one-leg standing time, compared with 41 of 101 with eyes open.
02In the 87 participants with balanced hip internal rotation, the same-side one-leg standing pattern was 50 with eyes open and 7 with eyes closed.
03In the 14 participants with hip internal rotation imbalance, the one-leg standing pattern matched the hip rotation pattern in 3 with eyes open and in 11 with eyes closed.

What it does not show
The participants were healthy young physical therapy students, not older adults or patients with balance problems. The hip-rotation imbalance group was small. The one-leg standing test had a maximum time, so people who could stand on both sides for that long were counted as having no difference. Hip rotation was measured in coarse increments, and one-leg standing time was measured once. The study measured associations only. It did not test whether hip rotation or eyes-closed standing predicts falls.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that hip internal rotation asymmetry predicts falls or that eyes-closed one-leg standing is a clinical fall test. The study was in healthy young physical therapy students, used a maximum one-leg standing time, and did not measure falls.
