title = "Improved compensatory postural adjustments of the deep abdominals following exercise in people with chronic low back pain",
abstract = "The purpose of this study was to determine if 8 weeks of exercise affects motor control in people with chronic low back pain (CLBP), measured by anticipatory (APAs) and compensatory postural adjustments (CPAs). APAs and CPAs were measured prior to and following 8 weeks in two groups of people with CLBP: an exercise group (n=12) who attended three exercise sessions per week for 8 weeks; and a non-exercise control group (n=12) who were advised to continue their usual activities for the duration of the study. APAs and CPAs were recorded during unilateral arm flexion, bilaterally from rectus abdominis (RA), transverse abdominis/internal oblique (TA/IO), and erector spinae (ES) via surface electromyography. Analysis of muscle onsets and APA amplitudes suggests APAs did not change for either group. Ipsi-lateral TA/IO CPAs increased for the exercise group and ipsi-lateral TA/IO CPAs decreased for the control group. Only exercise promoted a pattern of TA/IO activity during CPAs similar to healthy individuals, suggesting improved control of rotational torques. These results show motor control improvement following exercise in people with CLBP, highlighted by improved side specific control of TA/IO.",

note = "Funding Information: No conflicts of interests to declare. Michael Knox received his Honours degree in Health Science from Western Sydney University in 2013. Currently he is a PhD candidate in the Department of Sport and Exercise Science at Western Sydney University. His thesis aims to investigate motor control strategies in people with and without low back pain, and mechanisms that may explain changes following rehabilitation. Dr Chipchase is the Foundation Chair of Physiotherapy at Western Sydney Univesrity. She completed her PhD at the University of South Australia in 2007, and then established her research track record at the University of Queensland, prior to joining the University of Western Sydney. Her research has two main foci. First, Dr Chipchase uses non-invasive brain stimulation techniques to probe the motor cortex to determine the neuromodulatory effects of techniques used in neuromusculoskeletal rehabilitation. Second, she has a strong track record in evaluation and research within education. She has held a prestigious UQ Teaching Fellowship and a U21 Teaching and Learning Fellowship. Siobhan M Schabrun received her PhD in Neuroscience from The University of Adelaide and her Honours degree in Physiotherapy from The University of South Australia. She is a National Health and Medical Research Council of Australia Career Development Fellow at Western Sydney University where she leads the Brain Rehabilitation and Neuroplasticity research Unit. She is an Honorary Research Scientist at Neuroscience Research Australia. Her research interests include understanding why some people develop persistent musculoskeletal pain whereas others do not, and developing and testing brain-based treatments for musculoskeletal conditions. Dr. Paul Marshall graduated with his PhD in 2007, and is currently a clinical exercise physiologist based at Western Sydney University since 2010. His primary program of research examines how people with chronic disease and disability respond and adapt to exercise training, particularly those with chronic back pain. In addition, his research examines the relationships between muscle fatigability, injury prevention, and performance. The findings from his work have resulted in over 60 peer reviewed journal articles and successful industry and granting body funding success.
