abstract="PURPOSE: To examine head impact incidence and head acceleration during experimentally induced falls as a function of age. <br><br>METHODS: 15 young adults (21.2±2.7) and 10 older adults (61.9±4.3 years) underwent 6 experimentally induced sideways falls. Participants fell sideways onto a 20cm crash pad. The number of head impacts was tabulated from video recordings and head acceleration was calculated from motion capture data. A total of 147 falls were analyzed. <br><br>RESULTS: The young group underwent 88 falls, in which 11.4% resulted in head impact. The older group underwent 59 falls, in which 34.5% resulted in head impact. A proportion analysis revealed older adults had a significantly greater proportion of head impacts than young adults (<i>X</i><sup>2</sup>(1) = 11.445, p = 0.001). A two-way ANOVA only revealed a main effect of head impact on acceleration (<i>F</i>(1,142) = 54.342, p<0.001). <br><br>CONCLUSION: The older adults experienced a greater proportion of head impacts during sideways falls. Head impact resulted in greater head acceleration compared to no head impact. Collectively, this data highlights the possibility that age-related neuromuscular changes to head control may result in elevated risk of fall-related TBIs. Future research examining mechanisms underlying increases in fall-related head impact is warranted.<p /> <p>Language: en</p>",
