“…Surprisingly, however, lower values were also measured in the Nonper group as compared with the control group (Norm), which indicates that visual fixation is an important compensatory mechanism in the Nonper group (i.e., patients with central vestibular dysfunction) (Figure 1). A difference in the findings between patients with peripheral and central disorders has also been reported by Baloh [2].…”

“…The posturograph measures CFP distance To quantify an activity necessary to maintain stability, the posturograph measures CFP trajectory per a fixed period Way, W; [cm/s]) upon visual fixation (open eyes; Wf) and suppression (closed eyes; Ws), the area obtained by CFP trajectory (Area: Af, As; [cm 2 /s]), deviation of CFP in the anteroposterior X and lateral Y axes and their ratios upon visual fixation (ALf) and suppression (ALs) and visual balance control expressed in terms of Way (RW = Wf/Ws) and Area (RA = Af/As). These parameters were also studied in the presented communication.…”

“…This enables a detailed assessment of postural balance, a comparison of results, and an ability to archive [1]. Dynamic posturography (DPG) is presented as a method for the detection of stance and dynamic movement, with the capacity to quantify the information inputs, central integration, and mechanisms for creating effective postural movements [1,2]. Static posturography is based on the principle of measuring the shifts in CFP on a stationary platform [3][4][5].…”

“…Opinions on the importance of posturography and its position among other machine-based techniques in vestibulology are divided. 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.

“…A reduction in falling has been associated with a higher risk of falls 25 . Also, the increase in body oscillation is directly related to an increase in the frequency of falls 21 . The predominance of individuals with a higher risk of falls (62%) in the present study can be explained by the fact that the elderly with chronic peripheral vestibular dysfunctions and body balance disorder have an important loss in their sensorial systems, especially visual and vestibular, producing inadequate motor responses and body mass center projection close to the body's limit of stability, resulting in a greater risk of falling 26 .…”

Vest ibular disorders are common among the elderly, mainly resulting in dizziness and imbalance -symptoms which can impact daily routine activities. Aim:To study the correlation between body balance and functional capacity and a comparison of risk of falls, actual falls and the functional capacity of the elderly with chronic vestibular dysfunctions. Materials and Methods:A cross-sectional, clinical and experimental study with 50 senior citizens -60 to 86 years, with chronic peripheral vestibular dysfunction. These participants underwent body balance assessment by the Dynamic Gait Index (DGI) and functional capacity assessment by the Functional Independence Measure (FIM). The data was tested using the Spearman correlation and comparison tests, Mann-Whitney and Kruskal-Wallis, being α=5% (0.05).Results: There was a significant correlation between the total DGI score and all FIM scores, especially the total score (r=0.447; p<0.001) and loss of functional capacity in elderly patients with the highest risk of falling (p<0.001). Conclusion:There is a positive correlation between body balance and functional capacity in elderly patients with peripheral vestibular disorders, that is: the better the balance, the better the individual's functional capacity. In addition, a worse functional capacity increases the individual's risk of falling. Braz J Otorhinolaryngol. 2011;77(6):791-8. ORIGINAL ARTICLE

New analyses of the sensory organization test compared to the clinical test of sensory integration and balance in patients with benign paroxysmal positional vertigo

Objective To determine whether the Sensory Organization Test (SOT) of the computerized dynamic posturography battery or the Clinical Test of Sensory Integration and Balance (CTSIB) is more likely to indicate balance disorders in people with benign paroxysmal positional vertigo. Study design Normal controls were compared to patients with unilateral benign paroxysmal positional vertigo of the posterior semicircular canal (BPPV). Methods Subjects performed tests with eyes open or closed on stable and unstable surfaces, with head still or with head moving at 0.33 Hz in pitch or yaw. Dependent variables were the percent time of the standard duration each subject could perform the task, the number of head motions made, and kinematic variables measured with head- and torso-mounted inertial motion units. Results Because equilibrium scores of normals improved significantly over repeated trials on SOT patients were given only 1 trial per condition. For percent time between-group differences were found on CTSIB with eyes closed, on foam, head moving in yaw showing significantly reduced performance by BPPV subjects compared to controls. Compared to controls patients made significantly fewer head movements on CTSIB, eyes closed, on foam, head still, pitch and yaw. Kinematic data also differed between the groups on tests with eyes closed, unstable surfaces with different head movement combinations, indicating increased instability in BPPV patients. Conclusion For screening, CTSIB with head movements is more likely than SOT to indicate balance deficits, especially when dependent measures include percent time as well as head movement counts and kinematic measures.
