Background: Postural control requires complex processing of peripheral sensory inputs from the visual, somatosensory and vestibular systems. Motion sensitivity and decreased postural control are influenced by visual-vestibular conflicts. The purpose of this study was to measure the difference between the postural control of healthy adults with and without history of sub-clinical chronic motion ...

Human balance function depends on sensory inputs from the vestibular, proprioceptive, and visual systems as well as proper integration of those inputs in the central nervous system (CNS). Control of movements requires the motor centres to accurately process the sensory information and transmit the necessary commands to the appropriate muscles. Both structural and functional deteriorations in al...

Background Sitting posture is a common aggravating factor for pain both at the cervical and lumbar spine regions, with extended periods of sitting associated with increased discomfort at the neck and upper and lower back. Sitting postures independently adopted by asymptomatic individuals in comparison to theorized ‘optimal’ sitting postures have not been fully evaluated (O’Sullivan et al., 2010...

Background Painful adult scoliosis presenting kyphotic evolution combined with an anterior imbalance of the trunk is one of the most difficult clinical conditions in rehabilitation. Clinical changes during rehabilitation treatment (physical therapy) can be measured by using surface topography, although postural changes can produce measurement fluctuations, and interpretations should be made cau...

Methods We evaluated 35 consecutive female patients visited in ISICO Institute for spine diseases (scoliosis or hyperkyphosis). With the patient in a standing position, we carried out a set of tests performed with a three-dimensional rastereography (DIERS Formetric) with different SLs (5mm, 10mm, 15mm.) placed alternatively under both feet. We assessed the variations of these different postural...

Vestibular lesions may cause imbalance that long outlasts vertigo. Photographic analysis in five cases showed defects not only of the tilting reactions, which are of labyrinthine origin, but also of certain other postural reactions, notably the counterpoising and protective stepping reactions. All of these reflexes are unconscious and consequently such patients are rendered unstable in several ...

The function of the vestibular system is to transduce the forces of gravity and movement into neurological signals that the brain can use to develop an awareness of the position of the head in space and to coordinate head movements with motor reflexes responsible for ocular and postural stability. Not surprisingly, lesions of the vestibular system commonly result in abnormal posture of the head...

Dizziness and imbalance are the most common complaints in older people, a growing public health concern. Although causes of dizziness people multifactorial, peripheral vestibular dysfunction is one frequent causes. Every factor associated with maintenance postural stability deteriorates aging. Age-related deterioration function has been demonstrated through quantitative measurements vide head i...
