“… 13 This decrease in postural sway is probably related to postural freezing phenomenon, 39-41 which is observed in participants who view unpleasant images (mutilated or people in pain). 39-41 It seems that these changes represent a kind of anticipatory anxiety posture, 42 , 43 which in this case was induced threatening situation, in which the platform was elevated platform at different heights.…”

The influence of fear of falling on orthostatic postural control: a systematic review

Posture is a complex sensory-motor behavior that can be influenced by the fear of falling (FoF) during environmental changes. The aim of this paper is to investigate the influence of FoF on orthostatic postural control in healthy individuals by a systematic review. Thirteen articles were selected. Some other articles (31 references) were used to contextualize and discuss the topic. Studies in the environment made changes on the environment, in which participants were positioned in high hydraulic platforms at different heights, showed a decrease in the center of pressure in the anteroposterior oscillation where the platform was higher. This change in postural control strategy and the FoF are correlated. It can modulate the activity of the muscle spindle (H-reflex) and probably induce postural freezing phenomenon (anticipated postural anxiety). We can conclude that further studies are needed to understand the physiological echanisms involved in FoF and its relation to changes in postural control strategy.

“…Furthermore, demands other than anxiety influence postural control, even in the face of postural threat. For example, Young and colleagues 48 found that study participants with or without compensated vestibular deficits, standing at height or floor level, on a stationary or translating platform used one postural control strategy with eyes open (i.e., stabilization of head in space) and another one with eyes closed (i.e., stabilization of body on the platform). All participants prioritized head stabilization in the eyes-open condition, likely to promote gaze fixation regardless of postural challenges, whereas they favored body stabilization with eyes closed as there was no need to fix gaze.…”

Threat Assessment and Locomotion: Clinical Applications of an Integrated Model of Anxiety and Postural Control

Interactions between anxiety and vestibular symptoms have been described since the late 1800s. Typically, they have been conceptualized as bidirectional effects of one condition on the other (i.e., anxiety disorders as a cause of vestibular symptoms and vestibular disorders as a cause of anxiety symptoms). Over the past 30 years, however, a steady progression of neurophysiological investigations of gait and stance under conditions of postural threat, neuroanatomical studies of connections between threat assessment and vestibular pathways in the brain, and clinical research on anxiety-related vestibular conditions has offered the building blocks of a more integrated model. In this newer concept, threat assessment is an integral component of spatial perception, postural control, and locomotion in health and disease. It is not imposed on the vestibular system from the outside or simply reactive to vestibular dysfunction, but an inherently necessary part of every aspect of mobility. In this article, the authors review evidence that supports this model and then use it to examine common neurotologic conditions in which anxiety-related processes play important roles-fear of falling, primary and secondary anxiety disorders in patients with vestibular symptoms, and chronic subjective dizziness.

“…Stabilometry is increasingly widely used, and has been successfully used in patients with social anxiety disorders [ 17 ], in individuals with Parkinson’s disease [ 18 ], and to assess the effects of drugs on postural control, by recording the area that these subjects need to maintain balance [ 19 ].…”

Background: A force platform must have validity and reliability for optimal use. The objective of this study was to analyze the validity and the reliability of the Satel 40 Hz stabilometric force platform. Methods: A study of instrumental validity and reliability, involving a cross-sectional correlational and comparative analysis was performed. To determine the validity, four certified weights located on three axes were used and the ability of the stabilometric force platform to detect changes in the position of the different axes was observed. A test–retest was performed to analyze the reliability. Forty-two symptom-free volunteers participated in the study. Assessments were taken in a standing static position and in a dynamic position, with the eyes open and closed. Three measurements were taken and the intra-class correlation coefficient (ICC) was calculated. Results: The validity increased as the weight increased for all the variables measured in the stabilometric parameters (p < 0.05). The reliability was shown to be good to excellent for the two visual conditions. The positional variables obtained a higher ICC. The variable with the best ICC was the Y mean in OE (ICC 0.874 and a p < 0.001). All the values showed an increase in a dynamic situation. Conclusion: The findings support the reliability and validity of the Satel 40 Hz stabilometric force platform. The platform could be recommended to evaluate static and dynamic standing balance in healthy adult individuals. Guidelines for treatment and the level of quality of stabilometry could be obtained from its use.
