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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
