The Effect of Total Knee Arthroplasty on Knee Joint Kinematics and Kinetics During Gait
(Elsevier, 2011-02)This study determined how total knee arthroplasty (TKA) altered knee motion and loading during gait. Three-dimensional kinematic and kinetic gait patterns of 42 patients with severe knee osteoarthritis were collected 1 ... -
Temporal coactivation of abdominal muscles during dynamic stability exercises
(Wolters Kluwer, 2010-05)The purpose of this study was to determine abdominal muscle temporal responses to a leg-loading exercise protocol and if differences exist between those able and unable to minimize lumbar-pelvic motion during this protocol. ... -
Characterisation of trunk muscle activation amplitude patterns during a simulated checkstand operation with continuously changing flexor and lateral moment demands
(Taylor & Francis, 2010-04)While the typical physical exposure to modern-day workers has changed from heavy to low level repetitive demands, there is limited research that examines light occupations. This study examined trunk muscle recruitment ... -
The interpretation of abdominal wall muscle recruitment strategies change when the electrocardiogram (ECG) is removed from the electromyogram (EMG)
(Elsevier, 2009-04)The purpose of this study was to determine the effect of the ECG artifact on low-level trunk muscle activation amplitudes and assess the effectiveness of two methods used to remove the ECG. Simulations were performed and ... -
Activation amplitude patterns do not change for back muscles but are altered for abdominal muscles between dominant and non-dominant hands during one-handed lifts
(SpringerLink, 2009-05)It is assumed when lifting with the dominant hand that the relationship between contralateral and ipsilateral trunk muscle responses are similar to when lifting with the non-dominant hand. The purpose of this study was to ... -
Electromyographic assessment of trunk muscle activation amplitudes during a simulated lifting task using pattern recognition techniques
(Elsevier, 2009-12)This study sought to determine the patterns of neuromuscular response from 24-trunk muscle sites during a symmetrical lift and replace task. Surface electromyograms (EMG) and kinematic variables were recorded from 29 healthy ... -
Differences in Abdominal Muscle Activation Patterns of Younger and Older Adults Performing an Asymmetric Leg-Loading Task
(Elsevier, 2009-11)Objectives: To determine whether differences exist between younger (20-50 years) and older adults ( 65 years) in abdominal muscle amplitudes, temporal patterns, and threedimensional (3D) pelvic motion, while performing ... -
Impact of pharmacists as immunizers on vaccination rates: a systematic review and meta-analysis
(2016)Background: Underutilization of vaccination programs remains a significant public health concern. Pharmacists serve as educators, facilitators, and in some jurisdictions, as administrators of vaccines. Though pharmacists ... -
Asymptomatic and symptomatic individuals with the same radiographic evidence of knee osteoarthritis walk with different knee moments and muscle activity
(Wiley, 2016-11-01)There is an established discordance between the structural joint damage and clinical symptoms of knee osteoarthritis; however, there has been little investigation into the differences in joint level biomechanics and muscle ... -
Obesity is associated with prolonged activity of the quadriceps and gastrocnemii during gait
(Elsevier, 2015-12)Purpose: To examine the effect of obesity and its potential interaction with knee OA presence on the electromyography patterns of the major knee joint periarticular muscles during walking. Scope: One hundred and eighteen ... -
Obesity is associated with higher absolute tibiofemoral contact and muscle forces during gait with and without knee osteoarthritis
(Elsevier, 2016-01)Background Obesity is an important risk factor for knee osteoarthritis initiation and progression. However, it is unclear how obesity may directly affect the mechanical loading environment of the knee joint, initiating ... -
Effect of a high intensity quadriceps fatigue protocol on knee joint mechanics and muscle activation during gait in young adults.
(SpringerLink, 2012-02)The purpose of this study was to determine the effect of impaired quadriceps function on knee joint biomechanics and neuromuscular function during gait. Surface electromyograms, three-dimensional motion and ground reaction ... -
Activation amplitude and temporal synchrony among back extensor and abdominal muscles during a controlled transfer task: comparison of men and women
(Elsevier, 2012-08)Muscle synergies are important for spinal stability, but few studies examine temporal responses of spinal muscles to dynamic perturbations. This study examined activation amplitudes and temporal synergies among compartments ... -
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 ... -
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. ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ...
