Older adults often encounter postural stability problems due to a deteriorated postural control. Critical for this is the ability to select and reweight alternative sensory inputs. Numerous papers have reported results using Center of Pressure (CoP) data to asses postural control under different sensory conditions. Although, the differential effect(s) that combinations of sensory manipulation could have for young and older adults are not clear yet. The aim of this study was to 1) study the effects of different sensory cues on postural control; 2) examine differential effects of these cues in young and older adults. Twenty-five young (26.8±6.8 years) and 19 older adults (71.9±17.3 years) stood quite during one minute with varying head position (HP) (normal - extended), surface (normal - foam), and vision (eyes open - closed) while trunk movement was measured with an iPod. A repeated measures ANOVA showed significant effects of task on all parameters and 2-way interaction effects of HP x surface and vision x surface, indicating that postural control is influenced by the interaction between the sensory cues. Older adults showed higher values for all parameters in antero-posterior direction and 2-way interactions of HP x age and surface x age, indicating that the they had less postural control in challenging conditions. The age-related changes in postural control sensory reweighting measured with an iPod can be valuable information for the clinic to discriminate between the various sources of ageing and possible impairments.
