OBJECTIVES To examine vestibular control of balance in those who recovered the ability to stand after middle cerebral artery (MCA) stroke. METHODS Sixteen patients with MCA stroke were compared with 10 age matched controls. Two additional patients were studied with isolated corticospinal tract lesions, one each at the level of the pons and medulla. Vestibular evoked postural responses were ob...

This work studied biped walking with single (one-leg) support and balance control using reinforcement learning. The proposed Q-learning algorithm makes a robot learn to walk without any previous knowledge of dynamics model. This balance control with single support shifts the Zero Moment Point (ZMP) of the robot to a stable region over walking sequences by means of learned gestures. Hence, the p...

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...

This paper presents balance control of humanoid robot for HuroSot using its upper body motion and swinging two arms. The upper body is modeled as an inverted pendulum for an on-line compensation. By using the upper body motion it compensates ZMP (Zero Moment Point) error, obtained by FSR (Force Sensitive Resistor) sensors attached on the sole of the foot. Also by swinging the arms it can cancel...

Past studies of postural control during standing have employed wide range of procedures including the outcome measures use to quantify postural control, the duration of the sample collected, sampling frequency and methods for data processing. Due to these differences there remains little, if any, common grounds for comparisons between studies to establish a concrete understanding of the feature...

PURPOSE OF REVIEW Disorders of spatial awareness and balance following stroke are common but often under-diagnosed. They lead to poor outcome and frequently coexist. Here we focus on recent progress in the understanding of the mechanisms underlying these disorders and potential therapeutic advances. RECENT FINDINGS Right-hemisphere networks are important for both spatial attention and postura...

Abstract The direct energy balance control strategy is analyzed and combined with the characteristics of supercritical units. reconstructed. reconstructed signal applied to boiler master feedforward in coordinated control, taking a power plant’s system as an example, t. Thus, it units, which improves regulation quality steady dynamic state, effectively solves problems large fluctuation mainstre...
