Activation amplitude and temporal synchrony among back extensor and abdominal muscles during a controlled transfer task: comparison of men and women
Hubley-Kozey, CL; Butler, HL; Kozey, JW (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 ... -
Effect of a high intensity quadriceps fatigue protocol on knee joint mechanics and muscle activation during gait in young adults.
Murdock, GH; Hubley-Kozey, CL (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.
Astephen Wilson, JL; Dunbar, MJ; Hubley-Kozey, CL (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, ... -
Obesity is associated with prolonged activity of the quadriceps and gastrocnemii during gait
Amiri, P; Hubley-Kozey, CL; Landry, SL; Stanish, WD; Astephen Wilson, JL (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 ... -
Pre-operative muscle activation patterns during walking are associated with TKA tibial implant migration.
Wilson, DA; Hubley-Kozey, CL; Astephen Wilson, JL; Dunbar, MJ (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 ... -
Relationship between knee adduction moment patterns extracted using principal component analysis and discrete measures with different amplitude normalizations: Implications for knee osteoarthritis progression studies.
Hatfield, GL; Stanish, WD; Hubley-Kozey, CL (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 ...
