“…During bipedal upright stance, healthy human subjects demonstrate relatively small movements of the centre of pressure (COP) in anteroposterior or mediolateral directions and are able to keep the COP within the limits of the base of support and hence, maintain upright standing without falling or taking an additional step (Di Fabio 1995, Mochizuki et al 2006). …”

“…A reweighting of sensory input may occur quickly and acutely in response to sensory disturbance ) or chronically to compensate for persistent dysfunction of one system (Allum and Adkin 2003), and in some cases, compensation may not be complete. Therefore, static posturography represents a tool in order to objectivise dysfunction and compensation of the sensory systems due to conditions such as vestibulopathy (Corriveau et al 2001, Di Fabio 1995.…”

Preserving upright stance requires central integration of the sensory systems and appropriate motor output from the neuromuscular system to keep the centre of pressure (COP) within the base of support (BoS). Unilateral peripheral vestibular disorder (UPVD) causes diminished stance stability. The aim of this study was to determine the limits of stability and to examine the contribution of multiple sensory systems to upright standing in UPVD patients and healthy subjects. We hypothesised that closure of the eyes and Achilles tendon vibration during upright stance will augment the postural sway in UPVD patients more than in healthy subjects. Seventeen UPVD patients and 17 healthy subjects performed six tasks on a force plate: forwards and backwards leaning, to determine limits of stability, and upright standing with and without Achilles tendon vibration, each with eyes open and closed (with black out glasses). The COP displacement of the patients was significantly greater in the vibration tasks than the controls and came closer to the posterior BoS boundary than the controls in all tasks.Achilles tendon vibration lead to a distinctly more backward sway in both subject groups.Five of the patients could not complete the eyes closed with vibration task. Due to the greater reduction in stance stability when the proprioceptive, compared with the visual, sensory system was disturbed, we suggest that proprioception may be more important for maintaining upright stance than vision. UPVD patients, in particular, showed more difficulty in controlling postural stability in the posterior direction with visual and proprioceptive sensory disturbance.

“…Research has shown that exercise also increases brain-derived neurotrophic factors, which inhibit the destruction of normal brain cells and aid in the generation of new brain cells 2) . Many studies have also reported a correlation between balance ability and cognitive function and visual perception 3,4) . The literature generally classifies intervention methods for cognitive rehabilitation into traditional treatment methods and computer-aided cognitive rehabilitation (CACR) techniques.…”

Abstract. [Purpose] This study examined the effects of computer-aided cognitive rehabilitation (CACR) training and balance exercise on elderly individuals' cognitive and visual perception.[Subjects] Thirty healthy subjects aged between 65 and 80 participated in this study. They were randomly and equally assigned to either a CACR training group (TG) or a balance exercise group (BEG).[Methods] Subjects' cognitive functions and visual perception were measured using the Korean mini-mental state examination (MMSE-K) and the motor-free visual perception test (MVPT-3), respectively. For intervention methods, the TG received interval vision training using the RehaCom program, a Cognitive Rehabilitation Computer Program derived the Vienna Test System, and vision composition training with attention training programs for 30 minutes, 3 times per week, for 6 weeks. The BEG training consisting of warm-up exercises, main exercises, and cool-down exercises, for 50 minutes, 3 times per week, for 6 weeks.[Results] Both the TG and the BEG saw their MMSE-K and MVPT-3 scores significantly increase after the interventions, but the two groups showed no significant differences. [Conclusion] Given that the effects of CACR training were similar to those of the balance exercise training, we consider CACR training is a viable treatment method for preventing the decrease of cognitive function among the elderly.

“…Prevailing opinion is that both posturography techniques (SCPG and DCPG) are beneficial especially for the quantitative assessment of postural balance [2,6,7]. Posturography is deemed a suitable complement to standard vestibular examinations, especially in patients with CNS pathology and is useful for evaluating susceptibility to falling [8][9][10].…”

AbstractPosturography is a general term for techniques used to measure postural stability on static or dynamic measuring platforms. The principle of static computerised posturography (SCPG) is the detection of the centre of foot pressure (CFP) in upright stance on a posturography platform. Our communication deals with the importance of SCPG in differential topodiagnosis of vestibular syndromes in neurology. The set of examinations and evaluations carried out was divided among a control group of healthy subjects (77), a group of subjects with peripheral vestibular disorder (159), and a group of subjects with a non-peripheral balance disorder (82). Results obtained through the measurements were evaluated using descriptive statistics procedures and basic numerical and graphic statistical characteristics of the given groups. Our observations demonstrate that posturography is a valuable auxiliary test for balance disorders, especially given the lack of more suitable tests. According to our results, SCPG can be used for a rough differential topodiagnosis of balance disorders in neurology.
