The asymmetrical nature of hemiparetic gait is well known; however, the role of walking asymmetry for speed performance is unclear. The purpose of the present study was to determine whether the range of walking speeds in chronic hemiparetic patients is associated with their gait asymmetry and postural sway. Twenty ambulatory patients with chronic unilateral supratentorial infarction were studie...

Materials and methods Twenty children (mean age 9 years (SD2.3)) performed five running trials at a self-selected velocity barefoot and wearing school shoes (Daytona, Clarks) in a random order. A 14 camera 200Hz motion analysis system (EVaRT5.0, MAC) was used to calculate marker trajectories. Markers were attached to the right leg and a cluster wand was attached to the calcaneus through a windo...

Several models have been employed to study human postural control during upright quiet stance. Most have adopted an inverted pendulum approximation to the standing human and theoretical models to account for the neural feedback necessary to keep balance. The present study adds to the previous efforts in focusing more closely on modelling the physiological mechanisms of important elements associ...

Upright stance on a balance board is a skill requiring complex rearrangement of the postural control. Despite the large use of these boards in training the standing posture, a comprehensive analysis of the learning process underlying the control of these devices is lacking. In this paper learning to maintain a stable stance on a multiaxial oscillating board was studied by analyzing performance ...

[Purpose] The purpose of this study was to investigate the effect of aging on respiratory synergy, through the comparison of an elderly group and a young group, to help further understanding of postural control in the elderly. [Subjects and Methods] Ten community-dwelling elderly subjects and ten young subjects performed standing under two different respiratory conditions: quiet breathing and a...

Objective: To investigate whether vestibular rehabilitation for patients with whiplash-associated disorder and dizziness had any effect on balance measures and self-perceived handicap. Design: Randomized, controlled trial. Subjects: Twenty-nine patients, 20 women and 9 men, age range 22 76 years. Methods: The patients were randomized to an intervention group or a control group. The intervention...

BACKGROUND The Balance Error Scoring System (BESS) shows that balance tends to recover within days after a concussion, whereas measures of the movement of the center of pressure (COP) show that balance deficits can persist up to 1 month after concussion. While approximately 30% of adolescents suffering concussion have functional consequences including balance deficits, evidence of the use of di...

 Nomination and voting for this election is governed by conference standing order 74.  With the exception of those standing for the ‘seventh seat’, candidates do not have to be a representative of a local medical committee at conference.  Nominations may be made only by representatives of a local medical committee at conference.  A representative may make ONLY ONE nomination.  Elections, i...

Balance control when standing upright is a complex process requiring input from several partly independent mechanisms such as coordination, feedback and feedforward control, and adaptation. Acute alcohol intoxication from ethanol is recognized as a major contributor to accidental falls requiring medical care. This study aimed to investigate if intoxication at 0.06 and 0.10% blood alcohol concen...

This study was undertaken to evaluate the influence of weight shift over the affected leg of standing hemiplegic patients on the electromyographic responses of the medial gastrocnemius and tibialis anterior muscles during continuous anterior-posterior movements of the base of support. Recordings were taken from 10 hemiplegic subjects and from 9 healthy subjects of comparable age. Each subject w...
