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.

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.

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 ...

The visual, vestibular and muscle proprioceptive systems have all been shown to contribute to sway stabilization. Nevertheless, an additional receptor system is needed to signal the position of the body’s centre of gravity relative to the feet. This receptor system should be “gravity” dependent.

The Control of Posture and Locomotion
1973In this paper we have attempted to concentrate not so much on the apparent differences between standing and walking but rather on the common mechanisms shared by both actions. The analysis of the natural movements shows that during these two actions there is not only a successive change of postural and motor stabilisation modes but also a simultaneous ...

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 ...

While the phenomenon of balance (hereafter referred to as postural control) may seem inherently rudimentary to the casual observer, postural control is a complex and plural construct. Individuals with visual impairments (VIs) have historically presented with inferior postural control performance when compared to peers without VIs.

While my interest in the functional organization of the nervous system for the control of posture and movement sprang from the study of its diseases in neurological patients, my experiments and those of my numerous collaborators were performed just on cats and monkeys.

Postural control of the human mandible
Archives of Oral Biology, 2007This article reviews recent experimental evidence explaining the mechanisms that support the mandible in its rest or postural position when the head is stationary and during locomotion. At rest, and during slow jaw movements, there is alternating activation of the jaw-opening and jaw-closing muscles which arises from a central pattern generator ...
