| dc.description.abstract | Problem: Falls in older adults are prevalent in Canada which cause physical, psychological, emotional and financial stressors. With an increasingly older adult population, fall prevention is key in solving this problem. Learning how to prevent falls starts by understanding the difference(s) between older adults and younger adults in balance recovery mechanisms. Purpose: The purpose of this study is to investigate whether there were any age-related differences in stepping-lib joint moments and powers during the execution of a single-step compensatory balance response. Methods: A lean and release protocol was utilized to apply a balance disturbance to the participants. Participants were tasked to recover from the perturbation and restore stability using a single step with their preferred leg. The peak moment magnitude, peak moment power and timings of these peaks were recorded at the ankle, knee and hip in both the sagittal and frontal planes. Independent samples t-tests were used to compare joint-specific variables between older adults and younger adults to understand if age-related differences in stability may arise from challenges in moment generation or power absorption at specific joints. Results: Our results showed age-related differences in peak ankle moments in the sagittal plane as well as peak ankle power magnitudes in both the sagittal and frontal plane. In addition to these findings, our results also found key age-related differences in the timing of peak moments in the sagittal plane with both the hip and the knee joints as well as differences in the timing of peak power values in both the sagittal plane and frontal plane at the ankle, knee and hip joints. Conclusion: Age-related differences in the execution of the single-step compensatory response were found between older adults and younger adults. Our joint-specific findings can be used to further our understanding of balance control strategies in older adults but it also highlights the importance of timings in peak moment and power at the ankle, knee and hip which can be used to improve fall prevention and fall rehabilitation programs in older adults. | |
