In order to assess the influence of visual stimulation in the triggering of imbalance and falls in the elderly population, the postural responses of 18 elderly patients with central vestibular disorders and clinical evidence of instability and falls were studied while receiving different types of visual stimuli. The stimulation conditions were: (i) no specific stimuli; (ii) smooth pursuit with ...

INTRODUCTION Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life. Its association with vestibular symptoms is common, including imbalance and postural instability. OBJECTIVE To evaluate the body balance of patients with vestibular migraine through a static posturography test. METHODS An experimental group of 31 patients with...

Our purpose was to evaluate head stabilization in pitch plane in patients with different kinds of imbalance when standing over firm and movable surfaces. We used the STATITEST (Société Mumedia, Belgium), a multisegment platform for recording and computing postural adjustments at different body levels. We detected these data by two sensors placed on the head and hip of each subject in four situa...

The functional relevance of reactive gliosis for recovery from acute unilateral vestibulopathy is unknown. In the present study, glial activation was visualized in vivo by [18F]GE180-PET in a rat model of unilateral labyrinthectomy (UL) and compared to behavioral vestibular compensation (VC) overtime. 14 Sprague-Dawley rats underwent a UL by transtympanic injection of bupivacaine/arsenilate, 14...

Spasticity management is pivotal for achieving functional recovery of stroke patients. The purpose of this study was to investigate the effects of a single trial of transcutaneous electrical nerve stimulation (TENS) on spasticity and balance in chronic stroke patients. Forty-two chronic stroke patients were randomly allocated into the TENS (n = 22) or the placebo-TENS (n = 20) group. TENS st...

Background One of the etiologic agents of Idiopathic Scoliosis (IS) is the sensorineural and/or neuromuscular factor. J.P. Roll demonstrated that: 1) the muscle spindle is the postural adjustment source, 2) the right balance between agonist and antagonist muscles define the posture, 3) the feet are the gravity reference to the central nervous structures and 4) the sub-occipital muscles connect ...

In this study, we evaluated the goldfish model of hemilabyrinthectomy for investigating potential recovery-promoting drugs. In this lesion model, the unilateral removal of the labyrinth induces a postural imbalance in response to light (Dorsal Light Reflex), from which the animals can recover over time. The behavioral effects of two neuropeptides were tested--namely, of substance P and ACTH4-10...

BACKGROUND Strabismus surgery for congenital esotropia can be complicated by the development of a postoperative head tilt. PURPOSE To determine the pathophysiology of acquired head tilting following horizontal realignment of the eyes in children with congenital esotropia. MATERIALS AND METHODS Retrospective analysis of nine children with congenital esotropia who developed unexplained head t...

INTRODUCTION Idiopathic Scoliosis (IS), is a sub-class of paediatric spinal deformities that is of unknown origin, and is characterized by a complex three dimensional curvature of the spine that is accompanied by spatial disorientation of the thoracic cage and postural dyscontrol [1-3]. With the aim of guiding clinical decisions and enhancing clinical outcomes, previous work has identified risk...

objectives: the role of cognitive process for postural control was shown in dual task studies. however, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. this study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...
