Crossing a road safely is a complex task requiring good sensorimotor function and integration of information about traffic speed, distances and one's own speed. Poor judgement through age-related sensorimotor or cognitive impairment or a predispositi

To determine how the vestibular sense controls balance, we used instantaneous head angular velocity to drive a galvanic vestibular stimulus so that afference would signal that head movement was faster or slower than actual. In effect, this changed ve

Balance recovery from an unpredictable postural perturbation can be a challenging task for many older people and poor recovery could contribute to their risk of falls. This study examined associations between responses to unpredictable perturbations

Key points While it has been well described that prolonged rotational stepping will adapt the podokinetic sense of rotation, the mechanisms involved are not clearly understood. By studying podokinetic after-rotations following conditioning rotations

With the hypothesis that vestibular sensitivity is regulated to deal with a range of environmental motion conditions, we explored the effects of passive whole-body motion on vestibular perceptual and balance responses. In 10 subjects, vestibular resp

BACKGROUND: Among older people, undue risk taking could lead to falls, irrespective of physical ability. We investigated the interaction between risk-taking behavior and physical ability and its contribution to falls. METHODS: Participants (N = 294,

Inappropriate stepping in response to unexpected balance perturbations is more prevalent in older people and in those at risk of falling. This study examined responses to force-controlled waist pulls in young and older people, and sought to identify
