This study examines the evidence which supports the importance of maintaining relative abduction for effective reciprocal walking in high level paraplegic patients. In comparisons of orthoses, where this can only be achieved mechanically, those with higher lateral rigidity consistently showed greater levels of walking efficiency. The influence on hybrid(More)
In Australia, the introduced Common Myna (Acridotheres tristis) is commonly believed to aggressively displace native birds and outcompete them for food and nest resources. However, the current paucity of scientific evidence makes it difficult to devise appropriate management strategies for protection of urban bird populations. This study investigates the(More)
The provision of walking for paraplegic patients has therapeutic benefits but must be at a low energy cost. Although claims have been made regarding the need for high lateral stiffness in any orthosis targeted at this group, much of the supporting evidence was confusing. This paper presents the theoretical reasoning behind this claim and reviews recent(More)
Urbanisation typically results in a reduction of hollow-bearing trees and an increase in the density of particularly species, potentially resulting in an increased level of competition as cavity-nesting species compete for a limited resource. To improve understanding of hollow usage between urban cavity-nesting species in Australia, particularly parrots, we(More)
The variation of ground reaction forces with time for a complete hgo gait cycle using crutches has been synthesized from video recordings and force platform data. This has led to an understanding of the dynamics of hgo ambulation. The results show that when a patient used the orthosis the crutches provide a subtle control mechanism taking maximum advantage(More)
Seventy-two normal children aged between three and 12 years were assessed to establish their walking function. Speed of walking and heart rate were monitored continuously, both barefoot and in shoes, over eight consecutive lengths of a 25m walkway. Since heart rate is affected by speed, the physiological cost index (PCI)--which combines the two(More)
There are many reasons why a rigid ankle foot orthosis (AFO) may be prescribed. In some cases it is desirable that the rigidity is sufficient to maintain a constant ankle position throughout the gait cycle. There is a need to determine a design of cosmetic, lightweight AFO that provides the necessary stiffness whilst being acceptable to the patient,(More)
Using next-generation sequencing technology, we describe the complete mitochondrial genomes for 5 Australian passerine birds (Epthianura albifrons, Petroica phoenicea, Petroica goodenovii, Petroica boodang, and Eopsaltria australis). We successfully assemble each mitogenome de novo using just 1/8th of a Roche GL FSX 454 pyrosequencing plate. From the(More)
Ambulation for patients with total body involved cerebral palsy poses greater problems than those encountered in providing reciprocal walking for thoracic lesion paraplegic subjects. Experience with a prototype system showed that an orthosis which controls the movement of the lower limbs, in combination with a walking frame giving anterior support, enables(More)
