The variation of the balance strategy during the lifespan: a pilot stduy

Effect of Rotating Auditory Scene on Postural Control in Normal Subjects, Patients With Bilateral Vestibulopathy, Unilateral, or Bilateral Cochlear I…
2018
International audience; Objective: The aim of this study was to investigate the impact of a rotating sound stimulation on the postural performances in normal subjects, patients with bilateral vestibulopathy (BVP), unilateral (UCI), and bilateral (BCD cochlear implantees.Materials and Methods: Sixty-nine adults were included (32 women and 37 men) in a multicenter prospective study. The group included 37 healthy subjects, 10 BVP, 15 UCI, and 7 BCI patients. The average of age was 47 +/- 2.0 (range: 23-82). In addition to a complete audiovestibular work up, a dynamic posturography (Multitest Framiral, Grasse) was conducted in silence and with a rotating cocktail party sound delivered by headph…
Influence of nerve of origin and tumor size of vestibular schwannoma on dynamic posturography findings.
2006
Condition 5-score (C5S) and vestibular ratio (VER) correlate, but condition-6-score (C6S) and mean overall balance score (MOBS) do not, with the size of an inferior vestibular nerve (IVN) vestibular schwannoma (VS). In IVN VS patients the visual system plays a major role in the maintenance of postural stability.To test whether the size of a superior vestibular nerve (SVN) or IVN VS, as measured on MRI scans, correlates with computerized dynamic platform posturography (CDPP) findings and whether CDPP findings could preoperatively predict the nerve of origin of the VS.This was a retrospective study. Seventy-five consecutive VS patients were evaluated. C5S, C6S, VER, and MOBS were evaluated. S…
Whiplash injure and human body balance: a force platform analysis.
2009
Whiplash injury is common trauma in occidental countries, its evaluation is estimated commonly clinically. Posturography may be used to verify body human imbalance whiplash injury related. The aim of this study was to analyze human body equilibrium in both sexes and verify if posturographic test can be used to assess body human imbalance in subjects with whiplash injury. We selected 41 volunteers of both sexes to analyze human body balance trough a force platform of health subjects and subjects with whiplash injure. Recording the Centre of Pressure (CoP) movements of these groups with open and closed eyes, we found that in both sexes, subjects with cervical injure had a significant increase…
Evaluation of Podalic Support and Monitoring of Balance Control in Children with and without Dyslexia: A Pilot Study
2020
Background: The American Psychiatric Association has identified dyslexia as a neurobiological disorder. The aim of the study was to evaluate podalic support, balance control, and dyslexia’s effects on interpersonal relationships. Methods: Fifty-seven subjects were enrolled for this study. The subjects were divided into two groups. The experimental group was composed of children with diagnosis of dyslexia. The control group was composed of healthy subjects. Each subject underwent baropodometry and posturographic analysis. In addition, the Multidimensional Self-esteem Assessment test by Bracken was used for a precise measurement of self-esteem in both groups (TMA). Results: The static b…

OBJECTIVE With a combination of different sympathetic tests, we aimed to elucidate whether impairment of sympathetic function in Parkinson's disease (PD) is the consequence of a central or peripheral efferent dysfunction. METHODS Thirty-five patients with early-to-intermediate PD (median age: 63 years; IQR: 57-67 years; disease duration 1-9 years, 15 women) and 20 age- and sex-matched healthy controls (median age: 64.5 years; IQR: 58-68 years; 10 women) were recruited. Autonomic testing was performed in two subgroups and included the assessment of resting cardiovascular parameters, postprandial hypotension (PPH), orthostatic hypotension (OH), and vasoconstriction induced by intradermal micr…
Evaluation of movement and brain activity
2021
Clinical neurophysiology studies can contribute important information about the physiology of human movement and the pathophysiology and diagnosis of different movement disorders. Some techniques can be accomplished in a routine clinical neurophysiology laboratory and others require some special equipment. This review, initiating a series of articles on this topic, focuses on the methods and techniques. The methods reviewed include EMG, EEG, MEG, evoked potentials, coherence, accelerometry, coherence, posturography (balance), gait, and sleep studies. Functional MRI (fMRI) is also reviewed as a physiological method that can be used independently or together with other methods. A few applicat…
Vertigo and multiple sclerosis: aspects of differential diagnosis.
2002
Equilibrium disorders caused by involvement of brainstem and cerebellar structures are common in patients with multiple sclerosis (MS), but peripheral conditions such as benign paroxysmal positional vertigo (BPPV) can be sometimes confused with those of a central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these subjects. Among available diagnostic tools, electro-oculography, posturography and vestibular evoked myogenic potentials (VEMPs) are especially suited to assess vestibulo-oculomotor and vestibulospinal systems. This paper briefly describes the most recent otoneurologic diagnostic strategies for …
The “bouquet of flowers” appearance in medullary sponge kidney
2018
The “bouquet of flowers” appearance is a radiological finding described for the intravenous pyelography (IVP) diagnosis of medullary sponge kidney (MSK). It refers to contrast pooling in dilated tubular structures in renal papillae, giving a striated pattern to the renal medulla, which resembles a “bouquet of flowers”
Percutaneous Stone Manipulation
1981
Percutaneous stone manipulation by direct ultrasound disintegration, extraction or chemolysis was done on 34 patients. A total of 15 patients presented with an operatively established nephrostomy, while percutaneous nephrostomy and subsequent dilation of the nephrostomy channel were done in 19. The rate of complete stone clearance was 19 of 20 stones after percutaneous nephrostomy and 8 of 16 stones in the group with an operatively established nephrostomy. The primary goal, to remove obstructing pelvic stones, was achieved in all cases. There were no untoward side effects, such as back pressure damage owing to flushing of the collecting system during ultrasound disintegration, or persistent…
