Humans have elegant bodies that allow gymnastics, piano playing, and tool use, but understanding how they do this in detail is difficult because their musculoskeletal systems are extremely complicated. Previous studies have shown that common movements such as reaching for a coffee cup, cycling a bicycle, or playing the piano have common patterns across subjects. This paper shows that an arbitrary set of whole-body movements used to trace large closed curves have common patterns both in the trajectory of the body's limbs and in variations within those trajectories. The commonality of the result should spur the search for explanations for its generality. One such principle could be that humans choose trajectories that are economical in energetic cost. Another synergistic possibility is that common movements can be saved in segments that can be combined to facilitate the process of deployment.

Anthropometric models are used when body center of mass motion is calculated for assessment of dynamic balance. It is currently unknown how body segments and posture change in the postpartum period. T...
Anthropometry and body composition are plausible influences on pediatric sagittal standing posture. Despite that, the relationship of anthropometrics since birth and body composition with individual p...
The impact of body posture on vocal emission is well known. Postural changes may increase muscular resistance in tracts of the phono-articulatory apparatus and lead to voice disorders. This work aimed...
Humans develop posture and balance control during childhood. Interestingly, adults can also learn to master new complex balance tasks, but the underlying neural mechanisms are not fully understood yet...
Toe-out foot positioning is increasingly analyzed as a compensatory body-mechanical strategy to reduce pain and joint constraints in people with degenerative joint disease during gait. However, its in...
This study sets out to investigate the effect of a posture shirt on muscle activity during a sitting and standing repetitive upper limb task
The study was designed to investigate a possible influence of an occlusal stabilization splint on the body posture in TMD cases and controls. Interocclusal appliances or occlusal splints a...
The primary purpose of this investigation is to determine the predictive value of task persistence as measured by a mirror tracing task. A secondary purpose is to evaluate differences in ...
The role of head posture has been demonstrated in patient with dentofacial deformities. However, the relationship between body posture and jaw disorders is unclear. Moreover, patients with...
Postural-suprapostural task is defined as postural control takes place while at least one other concurrent task is being performed. In a postural-suprapostural task, appropriate prioritiza...
Identification of those persons (or animals) who have had such an association with an infected person, animal, or contaminated environment as to have had the opportunity to acquire the infection. Contact tracing is a generally accepted method for the control of sexually transmitted diseases.
The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.
The position or attitude of the body.
A POSTURE in which an ideal body mass distribution is achieved. Postural balance provides the body carriage stability and conditions for normal functions in stationary position or in movement, such as sitting, standing, or walking.
An induced response to threatening stimuli characterized by the cessation of body movements, except for those that are involved with BREATHING, and the maintenance of an immobile POSTURE.
