Maximal voluntary isometric contraction exercises: A methodological investigation in moderate knee osteoarthritis
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
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 ... -
Obesity is associated with higher absolute tibiofemoral contact and muscle forces during gait with and without knee osteoarthritis
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 ... -
Obesity is associated with prolonged activity of the quadriceps and gastrocnemii during gait
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 ... -
Pre-operative muscle activation patterns during walking are associated with TKA tibial implant migration.
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 ... -
Relationship between knee adduction moment patterns extracted using principal component analysis and discrete measures with different amplitude normalizations: Implications for knee osteoarthritis progression studies.
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 ... -
Reliability of Principal Components and Discrete Parameters of Knee Angle and Moment Gait Waveforms in Individuals with Moderate Knee Osteoarthritis
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 ... -
Reliability of surface electromyographic recordings during walking in individuals with knee osteoarthritis
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 ... -
Sit-to-stand transfer mechanics in healthy older adults: A comprehensive investigation of a portable lifting seat device.
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 ... -
State-related changes in MEG functional connectivity reveal the task-positive sensorimotor network
Functional connectivity measures applied to magnetoencephalography (MEG) data have the capacity to elucidate neuronal networks. However, the task-related modulation of these measures is essential to identifying the functional ... -

Temporal coactivation of abdominal muscles during dynamic stability exercises
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. ... -
Temporal Patterns of the Trunk Muscles Remain Altered in a Low Back–Injured Population Despite Subjective Reports of Recovery
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 ... -
Trunk neuromuscular pattern alterations during a controlled functional task in a low back injured group deemed ready to resume regular activities.
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 ...
