Activation amplitude patterns do not change for back muscles but are altered for abdominal muscles between dominant and non-dominant hands during one-handed lifts
Published version: : Butler, Heather L., Cheryl L. Hubley-Kozey, and John W. Kozey. "Activation amplitude patterns do not change for back muscles but are altered for abdominal muscles between dominant and non-dominant hands during one-handed lifts." European journal of applied physiology 106.1 (2009): 95-104. doi:10.1007/s00421-009-0994-9It is assumed when lifting with the dominant hand that the relationship between contralateral and ipsilateral trunk muscle responses are similar to when lifting with the non-dominant hand. The purpose of this study was to ... -
Asymptomatic and symptomatic individuals with the same radiographic evidence of knee osteoarthritis walk with different knee moments and muscle activity
Published version: Astephen Wilson, Janie L., William D. Stanish, and Cheryl L. Hubley‐Kozey. "Asymptomatic and symptomatic individuals with the same radiographic evidence of knee osteoarthritis walk with different knee moments and muscle activity." Journal of Orthopaedic Research (2016). doi:10.1002/jor.23465There 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
Published version: Hubley-Kozey, Cheryl L., et al. "Differences in abdominal muscle activation patterns of younger and older adults performing an asymmetric leg-loading task." PM&R 1.11 (2009): 1004-1013. doi:10.1016/j.pmrj.2009.09.018Objectives: 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 ... -
Electromyographic assessment of trunk muscle activation amplitudes during a simulated lifting task using pattern recognition techniques
Published version: Butler, Heather L., Cheryl L. Hubley-Kozey, and John W. Kozey. "Electromyographic assessment of trunk muscle activation amplitudes during a simulated lifting task using pattern recognition techniques." Journal of Electromyography and Kinesiology 19.6 (2009): e505-e512. doi:10.1016/j.jelekin.2008.09.010This 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 ... -
The interpretation of abdominal wall muscle recruitment strategies change when the electrocardiogram (ECG) is removed from the electromyogram (EMG)
Published version: Butler, Heather L., et al. "The interpretation of abdominal wall muscle recruitment strategies change when the electrocardiogram (ECG) is removed from the electromyogram (EMG)." Journal of Electromyography and Kinesiology 19.2 (2009): e102-e113. doi:10.1016/j.jelekin.2007.10.004The 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 ... -
Obesity is associated with higher absolute tibiofemoral contact and muscle forces during gait with and without knee osteoarthritis
Published version: Harding, Graeme T., et al. "Obesity is associated with higher absolute tibiofemoral contact and muscle forces during gait with and without knee osteoarthritis." Clinical Biomechanics 31 (2016): 79-86. doi:10.1016/j.clinbiomech.2015.09.017Background Obesity is an important risk factor for knee osteoarthritis initiation and progression. However, it is unclear how obesity may directly affect the mechanical loading environment of the knee joint, initiating ...
