Age-related changes in trunk neuromuscular activation patterns during a controlled functional transfer task include amplitude and temporal synergies
Quirk, D. A., & Hubley-Kozey, C. L. (2014). Age-related changes in trunk neuromuscular activation patterns during a controlled functional transfer task include amplitude and temporal synergies. Human movement science, 38, 262-280.While healthy aging is associated with physiological changes that can impair control of trunk motion, few studies examine how spinal muscle responses change with increasing age. This study examined whether older (over 65 ... -
Changes in electromyographic activity of trunk muscles within the sub-acute phase for individuals deemed recovered from a low back injury
Butler, Heather L., Cheryl L. Hubley-Kozey, and John W. Kozey. "Changes in electromyographic activity of trunk muscles within the sub-acute phase for individuals deemed recovered from a low back injury." Journal of Electromyography and Kinesiology 23.2 (2013): 369-377. doi:10.1016/j.jelekin.2012.10.012Evidence indicates that previous low back injury (LBI) is a strong predictor for re-injury. The purpose of this study was to examine whether neuromuscular patterns remain altered in a LBI group who were deemed recovered. ... -

"Co-activation differences in lower limb muscles between asymptomatic controls and those with varying degrees of knee osteoarthritis during walking." Clinical Biomechanics 24(5): 407-414. doi:10.1016/j.clinbiomech.2009.02.005Abstract: Background: Increased muscle co-activation during gait has been identified as a neuromuscular alteration associated with knee osteoarthritis, however levels of co-activation among different osteoarthritis severity ... -
Explaining the hip adduction moment variability during gait: Implications for hip abductor strengthening
Rutherford, D. J., & Hubley-Kozey, C. (2009). Explaining the hip adduction moment variability during gait: Implications for hip abductor strengthening. Clinical Biomechanics, 24(3), 267-273.Background There is emerging interest in hip abductor function during gait and its potential relationship to knee joint pathology. During gait, the hip abductor muscles are primarily responsible for generating moments of ... -
Hip abductor function in individuals with medial knee osteoarthritis: Implications for medial compartment loading during gait
Rutherford, D. J., Hubley-Kozey, C., & Stanish, W. (2014). Hip abductor function in individuals with medial knee osteoarthritis: Implications for medial compartment loading during gait. Clinical Biomechanics, 29(5), 545-550.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. ... -
