Users of traditional knee-ankle-foot orthoses (KAFOs) walk with either locked or unlocked knee joints depending on the level of stability required. Some users may benefit from new stance-control KAFOs that prevent stance-phase knee flexion but allow swing-phase flexion. We collected data from nine nondisabled adults who walked with KAFOs that incorporated the Horton Stance-Control Orthotic Knee...

Time periods composing stance phase of gait can be clinically meaningful parameters to reveal differences between normal and pathological gait. This study aimed, first, to describe a novel method for detecting stance and inner-stance temporal events based on foot-worn inertial sensors; second, to extract and validate relevant metrics from those events; and third, to investigate their suitabilit...

Speech conveys many things beyond content, including aspects of appraisal, feeling, and attitude that have not been much studied. In this work we identify 14 aspects of stance that occur frequently in radio news stories and that could be useful for information retrieval, including indications of subjectivity, immediacy, local relevance, and newness. We observe that newsreaders often mark their ...

Gait initiation (GI) involves passing from bipedal to unipedal stance. It requires a rapid movement of the center of foot pressure (CoP) towards the future swing foot and of the center of mass (CoM) in the direction of the stance foot prior to the incoming step. This anticipatory postural adjustment (APA) allows disengaging the swing leg from the ground and establishing favorable conditions for...

Research in academic writing has revealed a strong tendency on the part of writers to interactively communicate their scientific findings with their readers. In doing so, the writers should take a position while arguing their propositions. This interaction as proposed by Hyland (2005b) takes places having two sides of stance and engagement. This study targeted the stance component of writer-rea...

  Background : Biomechanical factors are known to be important in knee osteoarthritis (OA) development and progression. This study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.   Methods: 16 females (10 with mild and 6 with moderate medial knee osteoart...

Recent research has shown that academic writing is not ‘author-evacuated’ but, rather, carries a representation of the writers’ identity. One way through which writers project their identity in academic writing is stance-taking toward propositions advanced in the text. Appropriate stance-taking has proved to be challenging for novice writers of Research Articles (RAs), especially those writing ...

Knee osteoarthritis (OA) commonly occurs in the medial compartment of the knee and has been linked to overloading of the medial articular cartilage. Gait modification represents a non-invasive treatment strategy for reducing medial compartment knee force. The purpose of this study was to evaluate the effectiveness of a variety of gait modifications that were expected to alter medial contact for...
