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 ...
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, ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
