Lower Quarter Y-Balance Test in healthy women 50-79 years old.

The Lower Quarter Y-Balance Test (LQ-YBT), a measure of dynamic balance used in young adults, has not been adequately studied in older women. We determined the reliability, normative values, and relationships to other balance measures for LQ-YBT in women aged 50-79 years. Interrater reliability was strong, and test-retest reliability was moderate to strong.
