Background: The limit of stability (LoS), an index of stance balance ability, is reduced in older adults. Although contacting an earth-fixed external surface through fingertips' light touch improves older adults' stance balance control, its effects on the LoS in this population are unclear.
Research Question: Does light touch increase the LoS and reduce postural sway in the LoS?
Methods: This study included 20 young adults (11 women and 9 men, mean age = 20.
