How Crouch Gait Can Dynamically Induce Stiff-Knee Gait
No full textChildren with cerebral palsy frequently experience foot dragging and tripping during walking due to a lack of adequate knee flexion in swing (stiff-knee gait). Stiff-knee gait is often accompanied by an overly flexed knee during stance (crouch gait). Studies on stiff-knee gait have mostly focused on excessive knee muscle activity during (pre)swing, but the passive dynamics of the limbs may also have an important effect. To examine the effects of a crouched posture on swing knee flexion, we developed a forwarddynamic model of human walking with a passive swing knee, capable of stable cyclic walking for a range of stance knee crouch angles. As crouch angle during stance was increased, the knee naturally flexed much less during swing, resulting in a ‘stiff-knee’ gait pattern and reduced foot clearance. Reduced swing knee flexion was primarily due to altered gravitational moments around the joints during initial swing. We also considered the effects of increased push-off strength and swing hip flexion torque, which both increased swing knee flexion, but the effect of crouch angle was dominant. These findings demonstrate that decreased knee flexion during swing can occur purely as the dynamical result of crouch, rather than from altered muscle function or pathoneurological control alone.Biomechanical EngineeringMechanical, Maritime and Materials Engineerin
Selecting a Distributed Agreement Algorithm
No full textWhen component parts of distributed systems need to reach agreement, arriving at consensus is difficult if some components don’t behave properly. The Byzantine Generals Problem described by Lamport and others exemplifies the difficulty. In a real situation, components don’t know which of their peers are faulty and hence they cannot apply the algorithms of Lamport et al, nor even decide if a suitable algorithm exists. This paper discusses options available in this situation and describes how a good expectation of arriving at a consensus can be achieved without knowing for certain which or how many participants are behaving badly

No full textHow far is too far? Exploring the perceptions of the professions on their current and future roles in emergency care
No full textBackground and aims: How far is too far? Recent government policy and demographic growth have led to role changes within the professions in emergency care. Healthcare professionals have extended and expanded their scopes of practice to include duties outside their traditional role boundary. Nurses in particular are able to see and treat patients more independently. These expanded roles mean there is growing overlap between professional roles and responsibilities and one wonders—how far is too far? Where should role expansion cease? The aim of this research was to explore the perceptions of the professions on their current and future roles in emergency care. Methods: A qualitative design, utilising semistructured interviews was employed. Eight respondents, including doctors and nurses of all grades, were purposefully sampled from an emergency department within a large UK teaching hospital. Results: Content analysis revealed five key themes: role boundaries; driving forces; managing risk; training and future professional roles. Conclusions: Of genuine concern to the respondents was the lack of standardisation within the expansion of healthcare roles. In terms of "how far is too far", the respondents believed that greater clarification of training and scope of practice is required, enabling clinical roles to develop more consistently. <br/
