I. MOTIVATION The way how humans maintain balance during standing and locomotion has been an active area of research for many years now, with applications in bipedal robotics, leg prosthetics, and rehabilitation. However, most studies are limited to standing and walking on immobile surfaces, or on externally perturbed platforms and treadmills. Less is known about unstable, passive support surfa...

Motivation: Improved human control models could allow better understanding of the human sensorimotor control system and contribute to the design of devices to enhance human function or advance robotic performance. There is interest in especially natural control of human standing balance and walking. Humans seem to use specific postural strategies for upright balance or efficient walking algorit...

BACKGROUND The aim of this study was to assess the effectiveness of the unipedal standing balance exercise for 1 min to prevent falls and hip fractures in high-risk elderly individuals with a randomized controlled trial. This control study was designed as a 6-month intervention trial. SUBJECTS Subjects included 553 clinically defined high-risk adults who were living in residences or in the co...

[Purpose] To quantify the influence of visual and under-foot-surface conditions on standing balance in patients with post stroke hemiplegia and examine associations of this ordinal score with somatosensory disturbance and walking ability. [Subjects] Sixty-six patients with post-stroke hemiplegia. [Methods] Standing balance was tested in 4 conditions (firm floor or foam rubber surface with eyes ...

BACKGROUND Balance control during standing is essential while performing surgery. The postural sway must be controlled to enhance movement accuracy. Postural control was compared between novices and experts during standardized laparoscopic tasks. METHODS Seven novices with limited exposition to laparoscopy were compared with 7 expert surgeons. The subjects were requested to perform 4 laprosco...

There is evidence that traditional timedomain measures are not sensitive to the changing dynamic properties of the postural control system [1]. Frequency domain measures such as the spectral characteristics associated with sway may be more effective in detecting important but not easily identifiable changes in the physiological control systems underlying balance [1]. Frequency domain analysis h...

The postural control of children with and without developmental coordination disorder (DCD) was compared under conditions of reduced or conflicting sensory input. Twenty-two children with DCD (16 males, 6 females; mean age 7 years 6 months, SD 1 year 5 months) and 19 children with normal motor development were tested (13 males, 6 females; mean age 6 years 11 months, SD 1 year 1 month). Standing...

the aim of this research was to examine the effect of a training interventionprogram on fall-related motor performance in the male elderly with no regularphysical activities. for this purpose, 39 out of 130 participants in screen test wereselected and assigned to training group (n=20) and control group (n=19). subjectsaged between 60 and 70 in experimental were 73.68% and in the control group43...
