“…However, it is important to distinguish the two cases. The latter would mean that not only is shifting reliance from the visual to another, more appropriate frame of reference more difficult (Bugnariu and Fung 2007;Eikema et al 2012Eikema et al , 2013Slaboda et al 2011;Slaboda and Keshner 2012), but also that the visual frame of reference is not exploited in an optimal manner due to age effects. The correlations between visual field dependence and the other assessments support this idea: on the one hand, reduced visual fixation stability and useful field of view affect how visual information is perceived and processed; on the other, the diminished attention capacity (measured through the UFOV test) and reliability of egocentric cues (revealed via the RBT and weakened oculomotor control in the fixation task) make it more difficult to dynamically switch from one reference frame to another.…”

“…The main issue of increased visual field dependence is the implication of reduced adaptive and attentional capacities, both of which may be improved with appropriate training. Sensory reweighting (and ultimately learning to identify and utilize more appropriate frames of reference with respect to task constraints) has been shown to improve with time and/or practice in both young (Brady et al 2012) and old adults (Doumas and Krampe 2010;Eikema et al 2013;Jeka et al 2006), while physical activity in general ameliorates both cognitive and physical capabilities affected by age (Seidler et al 2010) and, in particular, preserves visuospatial functions (Shay and Roth 1992). Furthermore, taking visual field dependence into account in rehabilitation programs for sedentary old adults can lead to optimizing the use of the visual frame of reference, rendering visual field dependence more functional-as is done for young adults (Yan 2010) and Parkinson's patients (Azulay et al 2006).…”

“…Studies have shown that greater visual field dependence in old adults is associated with postural equilibrium alterations, increasing risk of fall (Eikema et al 2012;Jamet et al 2004;Lord and Webster 1990) and leads to more difficulty to perform dual tasks (Maylor and Wing 1996). Moreover, the implication of adaptation and sensory re-weighting difficulties for old adults (Bugnariu and Fung 2007;Eikema et al 2012;Eikema et al 2013;Slaboda et al 2011;Slaboda and Keshner 2012) means risk is even greater under sensory perturbation (e.g. walking on uneven terrain) or while in unfamiliar environments where vision in necessary to guide action.…”

Reliance on the visual frame of reference for spatial orientation (or visual field dependence) has been reported to increase with age. This has implications on old adults' daily living tasks as it affects stability, attention, and adaptation capacities. However, the nature and underlying mechanisms of this increase are not well defined. We investigated sensorimotor and cognitive factors possibly associated with increased visual field dependence in old age, by considering functions that are both known to degrade with age and important for spatial orientation and sensorimotor control: reliance on the (somatosensory-based) egocentric frame of reference, visual fixation stability, and attentional processing of complex visual scenes (useful field of view, UFOV). Twenty young, 18 middle-aged, and 20 old adults completed a visual examination, three tests of visual field dependence (RFT, RDT, and GEFT), a test of egocentric dependence (subjective vertical estimation with the body erect and tilted at 70°), a visual fixation task, and a test of visual attentional processing (UFOV®). Increased visual field dependence with age was associated with reduced egocentric dependence, visual fixation stability, and visual attentional processing. In addition, visual fixation instability and reduced UFOV were correlated. Results of middle-aged adults fell between those of the young and old, revealing the progressive nature of the age effects we evaluated. We discuss results in terms of reference frame selection with respect to ageing as well as visual and non-visual information processing. Inter-individual differences amongst old adults are highlighted and discussed with respect to the functionality of increased visual field dependence.

“…For example, using a unique combination of visual and somatosensory perturbations, Eikema, Hatzitaki, Konstantakos, and Papaxanthis (2013) found that advanced age brought an increased sensitivity to visual feedback coupled with a reduced sensitivity to tendon vibration. A common interpretation of these findings is that a decline in somatosensory feedback with age brings a greater reliance on visual feedback for postural control (Bugnariu & Fung, 2007; Eikema et al, 2013; Jeka, Allison, & Kiemel, 2010; Sundermier, Woollacott, Jensen, & Moore, 1996; Yeh, Cluff, & Balasubramaniam, 2014). In addition, Yeh et al (2014) found that visual reliance in old adults was direction-dependent, with greater sensitivity to visual perturbations in the mediolateral control of posture.…”

We implemented a virtual reality system to quantify differences in the use of visual feedback to maintain balance during walking between healthy young (n = 12, mean age: 24 years) and healthy old (n = 11, 71 years) adults. Subjects walked on a treadmill while watching a speed-matched, virtual hallway with and without mediolateral visual perturbations. A motion capture system tracked center of mass (CoM) motion and foot kinematics. Spectral analysis, detrended fluctuation analysis, and local divergence exponents quantified old and young adults’ dynamic response to visual perturbations. Old and young adults walked normally with comparable CoM spectral characteristics, lateral step placement temporal persistence, and local divergence exponents. Perturbed visual flow induced significantly larger changes in mediolateral CoM motion in old vs. young adults. Moreover, visual perturbations disrupted the control of lateral step placement and compromised local dynamic stability more significantly in old than young adults. Advanced age induces a greater reliance on visual feedback to maintain balance during waking, an effect that may compensate for degradations in somatosensation. Our findings are relevant to the early diagnosis of sensory-induced balance impairments and also point to the potential use of virtual reality to evaluate sensory rehabilitation and balance training programs for old adults.

“…We sampled the COP signal at 100 Hz 24 and filtered it using a fourth-order low-pass Butterworth filter with a 5-Hz 34 cutoff frequency. Because of filtering artifacts, we eliminated the first 10 frames (0.1 seconds given the 100-Hz sampling rate) from analysis, and for consistency, we did that with each segment (Pre, Vibration, Post).…”

Context: Proprioceptive training on compliant surfaces is used to rehabilitate and prevent ankle sprains. The ability to improve proprioceptive function via such training has been questioned. Achilles tendon vibration is used in motor-control research as a form of proprioceptive stimulus. Using measures of postural steadiness with nonlinear measures to elucidate control mechanisms, tendon vibration can be applied to investigate the underlying rationale of proprioceptive training.Objective: To test whether the effect of vibration on young adults' postural control depended on the support surface.Design: Descriptive laboratory study. Setting: Research laboratory.Patients or Other Participants: Thirty healthy adults and 10 adults with chronic ankle instability (CAI; age range ¼ 18À40 years).Intervention (s): With eyes open, participants stood in bilateral stance on a rigid plate (floor), memory foam, and a Both Sides Up (BOSU) ball covering a force platform. We applied bilateral Achilles tendon vibration for the middle 20 seconds in a series of 60-second trials and analyzed participants' responses from previbration to vibration (pre-vib) and from vibration to postvibration (vib-post). Main Outcome Measure(s):We calculated anterior-posterior excursion of the center of pressure and complexity index derived from the area under multiscale entropy curves.Results: The excursion response to vibration differed by surface, as indicated by a significant interaction of P , .001 for the healthy group at both time points and for the CAI group vibpost. Although both groups demonstrated increased excursion from pre-vib and from vib-post, a decrease was observed on the BOSU. The complexity response to vibration differed by surface for the healthy group (pre-vib, P , .001). The pattern for the CAI group was similar but not significant. Complexity changes vib-post were the same on all surfaces for both groups.Conclusions: Participants reacted less to ankle vibration when standing on the BOSU as compared with the floor, suggesting that proprioceptive training may not be occurring. Different balance-training paradigms to target proprioception, including tendon vibration, should be explored.
