Objective To determine and compare gait speed during head-forward and side-to-side head-turn walking in individuals with lower versus greater lateral balance. Design Cross-sectional study. Setting University research laboratory. Participants Older adults (N=93; 42 men, 51 women; mean age + SD, 73 + 6.08y) who could walk independently. Main Outcome Measures (1) Balance tolerance limit (BTL), defined as the lowest perturbation intensity where a multistep balance recovery pattern was first evoked in response to randomized lateral waist-pull perturbations of standing balance to the left and right sides, at 6 different intensities (range from level 2: 4.5-cm displacement at 180cm/s2 acceleration, to level 7: 22.5-cm displacement at 900cm/s2 acceleration); (2) gait speed, determined using an instrumented gait mat; (3) balance, evaluated with the Activities-specific Balance Confidence Scale; and (4) mobility, determined with the Timed Up and Go (TUG). Results Individuals with low versus high BTL had a slower self-selected head-forward gait speed and head-turn gait speed (P=.002 and P<.001 respectively the magnitude of difference was greater in head-turn gait speed than head-forward d="1.0" vs best predicted btl. btl moderately and positively related to abc scale negatively tug.> Conclusions Head-turn gait speed is affected to a greater extent than head-forward gait speed in older individuals with poorer lateral balance and at greater risk of falls. Moreover, head-turn gait speed can be used to assess the interactions of limitations in lateral balance function and gait speed in relation to fall risk in older adults. |
