Activation amplitude and temporal synchrony among back extensor and abdominal muscles during a controlled transfer task: comparison of men and women
Hubley-Kozey, Cheryl L., Heather L. Butler, and John W. Kozey. "Activation amplitude and temporal synchrony among back extensor and abdominal muscles during a controlled transfer task: Comparison of men and women." Human movement science 31.4 (2012): 863-879.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, Gillian Hatfield, and Cheryl L. Hubley-Kozey. "Effect of a high intensity quadriceps fatigue protocol on knee joint mechanics and muscle activation during gait in young adults." European journal of applied physiology 112.2 (2012): 439-449. doi:10.1007/s00421-011-1990-4 © 2012 SpingerLinkThe 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.
Wilson, Janie L. Astephen, Michael J. Dunbar, and Cheryl L. Hubley-Kozey. "Knee joint biomechanics and neuromuscular control during gait before and after total knee arthroplasty are sex-specific." The Journal of arthroplasty 30.1 (2015): 118-125.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
Published version: Amiri, P., et al. "Obesity is associated with prolonged activity of the quadriceps and gastrocnemii during gait." Journal of Electromyography and Kinesiology 25.6 (2015): 951-958. doi:10.1016/j.jelekin.2015.10.007Purpose: 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, David AJ, et al. "Pre-operative muscle activation patterns during walking are associated with TKA tibial implant migration." Clinical biomechanics 27.9 (2012): 936-942. doi:10.1016/j.clinbiomech.2012.06.012Background 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, Gillian L., William D. Stanish, and Cheryl L. Hubley-Kozey. "Relationship between knee adduction moment patterns extracted using principal component analysis and discrete measures with different amplitude normalizations: Implications for knee osteoarthritis progression studies." Clinical Biomechanics 30.10 (2015): 1146-1152.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 ...
