Noncontact of the unilateral hallux with the ground reduces forward limits of stability while standing.

[Purpose] Although hallux function is fundamental in maintaining forward leaning standing posture, the insight into whether noncontact of the hallux with the ground alters the forward limit of stability (LoS) remains unclear. Thus, we aimed to determine the effects of the unilateral hallux noncontact on the forward LoS while standing. [Participants and Methods] This study included 17 healthy young and 17 community-dwelling older adults.
