in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

physical exercise would improve postural stability, which is an essential factor in preventing accidental fall among the elderly population. the aim of this study is to examine the effectiveness of treadmill walking on balance improvement among the elderly people. a total of 30 community dwelling older adults with a berg balance scale score of 36-48 and the ability to walk without aid were cons...

objectives: the purpose of current study was to compare the effect of aging on balance in different sensory conditions. methods & materials: in this cross sectional study we compared 20 healthy youth (with age 22.75±2.29) and 20 healthy older adults (with age 65.1±4.16) in single leg standing in different sensory conditions. sensory conditions were open eye/ hard surface (oehs), closed eye/ har...

background the somatotype may influence the balance control ability. the quality of balance performance is an important factor to prevent injuries during sport activities. objectives the purpose of this study was to investigate the influence of somatotype on the static and dynamic balance indices as well as falling risk index. patients and methods a total of 141 university student healthy young...

Our goal was to provide some insights into how the CNS controls and maintains an upright standing posture, which is an integral part of activities of daily living. Although researchers have used simple performance measures of maintenance of this posture quite effectively in clinical decision making, the mechanisms and control principles involved have not been clear. We propose a relatively simp...

38 39 Distractions affect postural control, but this mechanism is not well understood. Diversion of 40 resources during cognitive stress may lead to decreased motor drive and postural muscle tone. 41 This may appear as decreased postural stiffness, and increased postural sway amplitude. We 42 hypothesized that dual tasking leads to decreased stiffness and increased sway amplitude. 43 Postural s...
