This study aimed to clarify the relationships between loads and gait changes and among gait parameters while walking with various loads. Fifteen healthy young male adults (mean age: 22.1+/-1.6 years) walked with four kinds of loads based on each subject's body mass (0, 20, 40, and 60% of body mass: BM) on his back. Walking speed, cadence, stance time, swing time, double support time, step lengt...

A SURVEY of the providers of medical treatment in mid-nineteenth-century Bristol, based mainly on data from the 1851 census, showed the herbalists and their allies as a small but definable group.' They tended to live in the poorest parts of the city and in this, as well as in many other characteristics, they were situated at the opposite social pole to the opulent physicians. Their patients mus...

An embryo of an enantiornithine bird has been recovered from the Lower Cretaceous rocks of Liaoning, in northeast China. The bird has a nearly complete articulated skeleton with feather sheet impressions and is enclosed in egg-shaped confines. The tucking posture of the skeleton suggests that the embryo had attained the final stage of development. The presence of well-developed wing and tail fe...

Evidence is increasing that brain areas that are responsible for action planning and execution are activated during the information processing of action-related verbs (e.g., pick or kick). To obtain further evidence, we conducted three experiments to see if constraining arm posture, which could disturb the motor planning and imagery for that arm, would lead to delayed judgment of verbs referrin...

Dr Haultain's " Plea for a Rational Puerperium," read before the Edinburgh Obstetrical Society last July (1), was concerned wholly with one event in that period?namely, the resumption of the erect posture by the lying-in patient. The claim was then made that recumbency after the third day and in an ordinary case was unnecessary, and that it was rational management to allow the puerperal woman t...

PURPOSE We compared postural stability and subjective visual vertical performance in a group of very preterm-born children aged 3-4 years and in a group of age-matched full-term children. MATERIALS AND METHODS A platform (from TechnoConcept) was used to measure postural control in children. Perception of subjective visual vertical was also recorded with posture while the child had to adjust t...

The goal of this study was to evaluate the performance of a single video camera system for measuring shoulder rotation during computer work, and to quantify the work and postural space within which the system performs optimally. Shoulder rotation angles calculated using the video system were compared with angles calculated using an active infrared LED three-dimensional motion analysis system wh...

Previous research has demonstrated a link between rotational behavior and striatal dopamine asymmetry in the rat (rats rotate contralateral to the side of higher striatal dopamine concentration) and that the direction of a rat pup's tail posture will predict rotational bias. The present study hypothesized that neonatal tail posture would also predict adult striatal dopamine asymmetry. This hypo...

The present experiment examined the effect of different approach motivational body postures on relative left frontal cortical activity, which has been linked with approach motivation. Three body postures were manipulated to create three levels of approach motivation. Consistent with the motivational direction model, results indicated that leaning forward with arms extended (high approach) cause...

BACKGROUND Posture and Stability Control is a process of maintaining balance and position of the body and its parts in a constantly changing environment. It is an important regulatory mechanism of the body, because it precedes movement, is upon the completion of which this system tries to maintain the body position. AIM The purpose of this long term study is to determinate by special testing ...
