Anosognosia for hemiplegia (AHP) is characterised by poor insight or underestimation of hemiplegia after brain injury. Recent explanations of AHP have used an established 'forward model', which proposes that normal motor awareness involves comparing the predicted and actual sensory consequences of movements. These accounts propose that AHP patients may be able to form representations of their i...

BACKGROUND Limited empirical information exists regarding botulinum toxin-A injector decision-making practices for adult upper limb post-stroke spasticity. The design of most studies prevents such an assessment, as injection sites and dosage are mandated by researcher protocols. This contrasts to usual injector practices, where individualized decision-making is the standard of care. DESIGN Se...

The importance of technique selection on elbow injury risk has been identified for the key round off skill in female gymnastics, with a focus on the second contact limb. The aim of this study was to shift the focus to the first contact limb and investigate the biomechanical injury risk during parallel and T-shape round-off (RO) techniques. Seven international-level female gymnasts performed 10 ...

This study examined ontogenetic patterns of limb loading, bone strains, and relative changes in bone geometry to explore the relationship between in vivo mechanics and size-related changes in the limb skeleton of two vertebrate taxa. Despite maintaining similar relative limb loads during ontogeny, bone strain magnitudes in the goat radius and emu tibiotarsus generally increased. However, while ...

Abstract Aim Limb reduction is a dramatic evolutionary transition, yet whether it achieved in similar trajectories across clades, and its environmental drivers, remain unclear. We investigate the macroevolutionary biogeographical patterns of limb skinks, where occurred more often than any other tetrapod clade, test their associations with substrate categories using global database. for habitat ...

this study aimed to investigate the relationship between race horse breed and the frequency of limb injuries through the time of training and racing. the study population consisted of 4042 thoroughbred and 2553 arabian horses raced at warsaw race track, from 2000 to 2008. among these horses, 94 thoroughbreds and 32 arabians had different limb injuries. based on the achieved results, it is possi...

As a group, lizards occupy a vast array of habitats worldwide, yet there remain relatively few cases where habitat use (ecology), morphology, and thus, performance, are clearly related. The best known examples include: increased limb length in response to increased arboreal perch diameter in anoles and increased limb length in response to increased habitat openness for some skinks. Rocky habita...

The Eph family of tyrosine kinase receptors has recently been implicated in various processes involving the detection of environmental cues such as axonal guidance, targeted cell migration and boundary formation. We have inactivated the mouse EphA4 gene to investigate its functions during development. Homozygous EphA4 mutant animals show peroneal muscular atrophy correlating with the absence of...

Socket is an important part of every prosthetic limb as an interface between the residual limb and prosthetic components. Biomechanics of socket-residual limb interface, especially the pressure and force distribution, have effect on patient satisfaction and function. This paper aimed to review and evaluate studies conducted in the last decades on the design of socket, in-socket interface pressu...

This review provides an overview of results found in literature on objective measurements of upper limb movements in children with hemiplegic cerebral palsy (HCP). Seventeen articles were selected following a systematic search. Analysed tasks varied from simple reaching and gross motor functions to complex, fine motor tasks. Spatiotemporal characteristics have been extensively studied and longe...
