Timings of attentional switching to perturbation and postural preparation during transient forward or backward floor translation
BACKGROUND: Relationships between the timings of attentional switching and postural preparation were investigated using a choice-reaction paradigm with transient floor translation (S2), with the direction indicated by a warning auditory signal (S1). METHODS: Thirteen healthy young adults participated in this study. S2 started 2 s after S1 onset while standing on the platform. The platform moved forward when S1 was a high tone, and backward when S…
Developmental changes in shortening of pro-saccade reaction time while maintaining neck flexion position
BACKGROUND: We investigated developmental changes in shortening of pro-saccade reaction time while maintaining neck flexion. METHODS: Subjects comprised 135 children (3-14 years) and 29 young adults (19-23 years). Children were divided into six groups in 2-year age strata. Pro-saccade reaction tasks for 30 s were performed in neck rest and flexion positions. Reaction times under each position were averaged in every 10-s period. RESULTS: Under nec…
Activation timing of postural muscles of lower legs and prediction of postural disturbance during bilateral arm flexion in older adults
BACKGROUND: Activation timings of postural muscles of lower legs and prediction of postural disturbance were investigated in young and older adults during bilateral arm flexion in a self-timing task and an oddball task with different probabilities of target presentation. Arm flexion was started from a standing posture with hands suspended 10 cm below the horizontal level in front of the body, in which postural control focused on the ankles is imp…
Postural control and contingent negative variation during transient floor translation while standing with the ankle fixed
BACKGROUND: Adaptation changes in postural muscle activity and anticipatory attention were investigated with the ankle joint fixed to change postural control strategies during transient floor translation. METHODS: For 15 healthy young adults, 40 transient floor translations (S2) in the anterior direction were applied 2 s after an auditory warning signal (S1), under conditions with or without fixation of the ankle. Activity of the frontal postural…
Event-related brain potential and postural muscle activity during standing on an oscillating table while the knee, hip, and trunk are fixed
BACKGROUND: In this study, a cast brace was used to immobilize the knee, hip, and trunk, and relations between the event-related brain potential (ERP) and postural muscle activity were investigated while standing on an oscillating table. METHODS: Twelve healthy young adults maintained a standing posture for 1 min per trial while oscillating in the anteroposterior direction at 0.5 Hz with a 2.5-cm amplitude. Trials were performed without and with …
Effect of time pressure on attentional shift and anticipatory postural control during unilateral shoulder abduction reactions in an oddball-like paradigm
BACKGROUND: The effect of time pressure on attentional shift and anticipatory postural control was investigated during unilateral shoulder abduction reactions in an oddball-like paradigm. METHODS: A cue signal (S1) - imperative signal (S2) sequence was repeated with various S2-S1 intervals (1.0, 1.5, and 2.0 s). S2 comprised target and non-target stimuli presented at the position (9° to the left or the right) indicated by S1. Right shoulder abduc…
Adaptation changes in dynamic postural control and contingent negative variation during repeated transient forward translation in the elderly
BACKGROUND: Adaptation changes in postural control and contingent negative variation (CNV) for the elderly were investigated during repeated forward floor translation. METHODS: Fifteen healthy elderly persons, living in the suburban area of Kanazawa City, Japan, underwent backward postural disturbance by a forward-floor translation (S2) 2 s after an auditory warning signal (S1). A set with 20 trials was repeated until a negative peak of late CNV …
Adaptation changes in dynamic postural control and contingent negative variation during backward disturbance by transient floor translation in the elderly
BACKGROUND: We investigated adaptation changes in dynamic postural control and contingent negative variation (CNV) in 13 young and 12 elderly adults. Subjects repeatedly underwent backward postural disturbance by a forward floor translation (S2) 2 s after an auditory warning signal (S1). Initial and second sets were conducted, each set with 20 trials. Posterior peak position of the center of pressure in the anteroposterior direction (CoPy) after …
The effects of neck flexion on cerebral potentials evoked by visual, auditory and somatosensory stimuli and focal brain blood flow in related sensory cortices
BACKGROUND: A flexed neck posture leads to non-specific activation of the brain. Sensory evoked cerebral potentials and focal brain blood flow have been used to evaluate the activation of the sensory cortex. We investigated the effects of a flexed neck posture on the cerebral potentials evoked by visual, auditory and somatosensory stimuli and focal brain blood flow in the related sensory cortices. METHODS: Twelve healthy young adults received rig…
Relationship between Quiet Standing Position and Perceptibility of Standing Position in the Anteroposterior Direction
We investigated the relationship between an individual's center of pressure in the anteroposterior direction in quiet standing (QS) and perceptibility of different standing positions. The position of the center of pressure in the anteroposterior direction (CoPy position) while standing was represented as the percentage distance (%FL) from the hindmost point of the heel in relation to foot length. CoPy position in QS was located from 31 to 58%FL. …
Eye Movement Performance and Prefrontal Hemodynamics during Saccadic Eye Movements in the Elderly
No previous study has investigated age-related changes in prefrontal hemodynamics during saccade tasks in a large number of elderly adults. The purpose of this study was to evaluate prefrontal activity related to the performance of anti-saccade in the elderly using near-infrared spectroscopy (NIRS). Ninety-six elderly adults and 22 young adults performed pro- and anti-saccade tasks. Measures included reaction times of both saccades, error rate du…
