    Asymptomatic and symptomatic individuals with the same radiographic evidence of knee osteoarthritis walk with different knee moments and muscle activity 

    Astephen Wilson, Janie L; Stanish, William D; Hubley-Kozey, Cheryl L (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 ...

    Differences in Abdominal Muscle Activation Patterns of Younger and Older Adults Performing an Asymmetric Leg-Loading Task 

    Hubley-Kozey, Cheryl L; Hanada, Edwin Y; Gordon, Sarah; Kozey, John W; McKeon, Melissa (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 ...

    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, ...

    Trunk neuromuscular pattern alterations during a controlled functional task in a low back injured group deemed ready to resume regular activities. 

    Hubley-Kozey, C; Moreside, JM; Quirk, DA (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 ...

    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 ...

    Sit-to-stand transfer mechanics in healthy older adults: A comprehensive investigation of a portable lifting seat device. 

    Rutherford, Derek; Hurley, Sean; Hubley-Kozey, Cheryl (Taylor & Francis, 2014)
    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 ...

    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 ...

    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 ...

    The interpretation of abdominal wall muscle recruitment strategies change when the electrocardiogram (ECG) is removed from the electromyogram (EMG) 

    Butler, Heather L; Newell, Robyn; Hubley-Kozey, Cheryl L; Kozey, John W (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 ...

    Electromyographic assessment of trunk muscle activation amplitudes during a simulated lifting task using pattern recognition techniques 

    Butler, Heather L; Hubley-Kozey, Cheryl L; Kozey, John W (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 ...
