Balance control strategies during perturbed and unperturbed balance in standing and handstand

Insights into sensorimotor control of balance were examined by the assessment of perturbed and unperturbed balance in standing and handstand postures. During perturbed and unperturbed balance in standing, the most prevalent control strategy was an ankle strategy, which was employed for more than 90% of the time in balance. During perturbed and unperturbed balance in handstand, the most prevalen...

Stiffness Control of Balance during Quiet Standing

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...

Human balance and posture control during standing and walking

The fact that we as humans are bipeds and locomote over the ground with one foot in contact (walking), no feet in contact (running), or both feet in contact (standing) creates a major challenge to our balance control system. Because two-thirds of our body mass is located two-thirds of body height above the ground we are an inherently unstable system unless a control system is continuously actin...

Direction-dependent control of balance during walking and standing.

Human walking has previously been described as "controlled falling." Some computational models, however, suggest that gait may also have self-stabilizing aspects requiring little CNS control. The fore-aft component of walking may even be passively stable from step to step, whereas lateral motion may be unstable and require motor control for balance, as through active foot placement. If this is ...

Dynamics Study of Ankle Joint during Quiet Standing Balance Control with Emphasis on Dominant and Non-dominant Lower Limb

Purpose: The present study aimed to evaluate the effect of dominant lower limb on the correlation between some of the dynamic variables of ankle joint and center of mass during quiet standing balance control. Methods: Twelve healthy females with no known neurological or musculoskeletal disorders, with the mean age of 26±3.5 years, participated in this study. Motion analysis system, force ...
