Age-related changes in muscle coordination patterns of stepping responses to recover from loss of balance

CONCLUSION: Although synergy structure was not affected by age, the delayed step onsets and the enhanced early synergy recruitment point at a relative bias towards non-stepping behavior in older adults. They may need more time for accumulating information on the direction of perturbation and making the corresponding sensorimotor transformations before initiating the step. Future work may investigate whether perturbation-based training improves these age-related deficits.PMID:38604252 | DOI:10.1016/j.exger.2024.112424
