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

ABSTRACTThe 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. Results by decade showed women 50–59 years had significantly better scores than both older groups. There were moderate positive correlations between single leg stance, gait speed, and LQ-YBT composite score. LQ-YBT may be used as a dynamic balance assessment in healthy older women.
