Adaptation of postural control to weightlessness
Experimental Brain Research, 1984Adaptation of motor control to weightlessness was studied during a 7-day spaceflight. The maintenance of control of upright posture was examined during a voluntary raising movement of the arm and during the voluntary raising on tiptoe. In order to evaluate the contribution of visual cues, three types of visual situations were examined: normal vision ...

On the cognitive penetrability of posture control
Experimental Aging Research, 1993Postural sway increases with age. The decreased stability associated with postural sway often has been related to the reduced peripheral sensibility in the visual, vestibular, and proprioceptive systems. We examined whether the micropostural adjustments necessary for maintaining balance also require some cognitive processing.

Afferent Control of Posture and Gait
Electroencephalography and Clinical Neurophysiology, 1985Investigations of the complex movements involved in human posture and gait have been restricted to the description of the efferent arm of the movement, in the form of biomechanical data and muscle electromyographic (EMG) activity. The extent to which the latter, while being generated by a central program, was also influenced by spinal reflex systems ...

Effects of Loratadine on Postural Control
Acta Oto-Laryngologica, 1995The effects of classical sedating antihistamines on cognitive and perceptual functions are well known. Loratadine is a new antihistamine without sedative effects. In this study, loratadine 10 and 40 mg daily, clemastine 2 mg twice daily and placebo were evaluated in 8 healthy subjects in terms of effects on equilibrium as measured with dynamic ...

Postural Control in the Older Adult
Clinics in Geriatric Medicine, 1996Age-related changes in the neural, sensory, and musculoskeletal systems can lead to balance impairments that have a tremendous impact on the ability to move about safely. The many complex substrates of the posture control system subserve a common functional goal: regulation of the relationship between the center of mass and the base of support ...

Postural control during kneeling
Experimental Brain Research, 2008Postural control was studied when the subject was kneeling with erect trunk in a quiet posture and compared to that obtained during quiet standing. The analysis was based on the center of pressure motion in the sagittal plane (CPx), both in the time and in the frequency domains.

Postural Control in Elderly Subjects
Age and Ageing, 1990The postural stability of 23 subjects aged 85 years or over was studied with a force platform. The sensory function of the lower limbs was disturbed with small vibrators placed on both calf muscles and/or by placing the subjects on a platform covered with foam plastic.

Postural control in healthy individuals
Clinical Biomechanics, 2010The aim of rehabilitation is to optimize functional recovery and frequently following injury, the uninjured limb is used as measure to compare with the injured limb. This assumes that symmetry existed prior to the injury. The aim of this study was to examine postural control in a healthy sample to ascertain if differences exist between the functionally

Postural control during lifting
Journal of Biomechanics, 2002Any voluntary motion of the body causes an internal perturbation of balance. Load transfer during manual material handling may increase these perturbations. This study investigates effects of stance condition on postural control during lifting. Nineteen healthy subjects repeatedly lifted and lowered a load between a desk and a shelf.

Balance prostheses for postural control
IEEE Engineering in Medicine and Biology Magazine, 2003There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery and as a permanent prosthesis for those elderly prone to falls.
