Reliability of Principal Components and Discrete Parameters of Knee Angle and Moment Gait Waveforms in Individuals with Moderate Knee Osteoarthritis
(Elsevier, 2013)Gait measures are used to evaluate change in patients with knee osteoarthritis (OA), but reliability has not been fully established in this population. This study examined test-retest reliability of knee angle and moment ... -
Sit-to-stand transfer mechanics in healthy older adults: A comprehensive investigation of a portable lifting seat device.
(Taylor & Francis, 2014)Purpose: To evaluate lower extremity mechanics and muscle activation associated with the sit-to-stand transfer using a portable lifting-seat device and to compare these data to an unassisted transfer in healthy young and ... -
Explaining the hip adduction moment variability during gait: Implications for hip abductor strengthening
(Elsevier, 2009)Background There is emerging interest in hip abductor function during gait and its potential relationship to knee joint pathology. During gait, the hip abductor muscles are primarily responsible for generating moments of ... -
Maximal voluntary isometric contraction exercises: A methodological investigation in moderate knee osteoarthritis
(Elsevier, 2011)Purpose: The objectives were, (i) to determine whether differences exist in relative activation amplitudes for participants with asymptomatic knees and participants with moderate medial compartment knee osteoarthritis ... -
Neuromuscular alterations exist with knee osteoarthritis presence and severity despite walking velocity similarities
(Elsevier, 2011)Background Neuromuscular strategies during walking in individuals with knee osteoarthritis are being explored for diagnostic information; however, isolating differences to disease progression is difficult given walking ... -
Reliability of surface electromyographic recordings during walking in individuals with knee osteoarthritis
(Elsevier, 2013)To determine test–retest reliability of a surface electromyographic protocol designed to measure knee joint muscle activation during walking in individuals with knee osteoarthritis (OA). Twenty-one individuals with moderate ... -
Changes in Knee Joint Muscle Activation Patterns during Walking Associated with Increased Structural Severity in Knee Osteoarthritis
(Elsevier, 2013)Purpose To determine whether alterations in knee joint muscle activation patterns during gait were related to structural severity determined by Kellgren–Lawrence (KL) radiographic grades, for those with a moderate knee ... -
Age-related changes in trunk neuromuscular activation patterns during a controlled functional transfer task include amplitude and temporal synergies
(Elsevier, 2014)While healthy aging is associated with physiological changes that can impair control of trunk motion, few studies examine how spinal muscle responses change with increasing age. This study examined whether older (over 65 ... -
Hip abductor function in individuals with medial knee osteoarthritis: Implications for medial compartment loading during gait
(Elsevier, 2014)Background Hip abductor muscles generate moments of force that control lower extremity frontal plane motion. Strengthening these muscles has been a recent trend in therapeutic intervention studies for knee osteoarthritis. ... -
Temporal Patterns of the Trunk Muscles Remain Altered in a Low Back–Injured Population Despite Subjective Reports of Recovery
(Elsevier, 2014)Objective To compare temporal activation patterns from 24 abdominal and lumbar muscles between healthy subjects and those who reported recovery from recent low back injury (LBI). Design Cross-sectional comparative ... -
Measuring Knowledge Translation Uptake Using Citation Metrics: A Case Study of a Pan-Canadian Network of Pharmacoepidemiology Researchers
(Taylor & Francis, 2016)ABSTRACT Collecting citation metric data is important, as research funders are increasingly demanding impact assessment, but there is limited consensus on the most rigorous and accurate approach. We compared three ... -
Community engaged scholarship to catalyze innovation: a case study of the uptake of portable inhalers for respiratory medication in a pediatric emergency department in Nova Scotia
(Longwoods Publishing, 2016)This commentary, in response to Tamblyn et al. (2016), provides a case study of the uptake of metered-dose inhalers with spacers to deliver respiratory medication in a pediatric emergency department in Nova Scotia. Our ... -
Relationship between knee adduction moment patterns extracted using principal component analysis and discrete measures with different amplitude normalizations: Implications for knee osteoarthritis progression studies.
(Elsevier, 2015-12-30)BACKGROUND: Knee adduction moment discrete features (peaks and impulses) are commonly reported in knee osteoarthritis gait studies, but they do not necessarily capture loading patterns. Principal component analysis ... -
Knee joint biomechanics and neuromuscular control during gait before and after total knee arthroplasty are sex-specific.
(Elsevier, 2015-01-30)The future of total knee arthroplasty (TKA) surgery will involve planning that incorporates more patient-specific characteristics. Despite known biological, morphological, and functional differences between men and women, ... -
Trunk neuromuscular pattern alterations during a controlled functional task in a low back injured group deemed ready to resume regular activities.
(IOS Press, 2014)BACKGROUND: Trunk neuromuscular alterations have been found in those with chronic low back pain, but less well studied are whether responses are altered in those deemed recovered following an injury. Furthermore, coordinated ... -
Changes in electromyographic activity of trunk muscles within the sub-acute phase for individuals deemed recovered from a low back injury
(Elsevier, 2013-04)Evidence indicates that previous low back injury (LBI) is a strong predictor for re-injury. The purpose of this study was to examine whether neuromuscular patterns remain altered in a LBI group who were deemed recovered. ... -
Pre-operative muscle activation patterns during walking are associated with TKA tibial implant migration.
(Elsevier, 2012-11)Background Gait biomechanical variables have been associated with total knee arthroplasty tibial implant migration measured with Radiostereometric Analysis (RSA), but no studies have examined the role of the periarticular ...
