BACKGROUND Amputation impairs the ability to balance. We examined adaptation strategies in balance following dysvascularity-induced unilateral tibial amputation in skilled prosthetic users (SPU) and first fitted amputees (FFA) (N = 28). METHODS Excursions of center of pressure (COP) were determined during 20 s quiet standing using a stabilometry system with eyes-open on both legs or on the no...

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...

We present a new test response compression method called cumulative balance testing (CBT) that extends both balance testing and accumulator compression testing. CBT uses an accumulated balance signature, and it guarantees very high error coverage (over 99%) for various error models. We demonstrate that the single stuck-line (SSL) fault coverage of CBT for many of the ISCAS 85 combinational benc...

This paper describes a walking gait for a humanoid robot with a distributed control system. The motion for the robot is calculated in real time on a central controller, and sent over CAN bus to the distributed control system. The distributed control system loosely follows the motion patterns from the central controller, while also acting to maintain stability and balance. There is no global fee...

Period doubling bifurcation in buck converters is studied by using the harmonic balance method. A simple dynamic model of a buck converter in continuous conduction mode under voltage mode or current mode control is derived. This model consists of the feedback connection of a linear system and a nonlinear one. An exact harmonic balance analysis is used to obtain a necessary and sufficient condit...

Increase (top) and decrease (bottom, vertical axis is inverted) of node balances in one month windows as a function of their balance at the beginning of each ...

Foot imbalance is an important cause of foot related lameness and should be assessed and addressed early on in the lameness investigation. Full assessment of the feet should involve inspection from lateral, dorsal and solar aspects with particular attention to foot and shoe balance, conformation and horn quality. Radiographs can be used as adjuncts to assessment. Trimming and shoeing protocols ...

in recent years, researchers have become interested in examining the effect of pettlep imagery on motor performance and how pettlep imagery can improve the performance. the aim of this study was to compare the effect of pettlep imagery and balance practice on dynamic balance in the elderly. participants were 42 male elderly in arak city. they were divided into 4 groups based on the scores of dy...
