Trunk-Pelvis Coordination During Turning: A Cross Sectional Study Of Young Adults With And Without A History Of Low Back Pain, Jo Armour Smith, Kornelia Kulig
Physical Therapy Faculty Articles and Research
Background
During steady-state locomotion, symptomatic individuals with low back pain demonstrate reduced ability to modulate coordination between the trunk and the pelvis in the axial plane. It is unclear if this is also true during functional locomotor perturbations such as changing direction, or if this change in coordination adaptability persists between symptomatic episodes. The purpose of this study was to compare trunk-pelvis coordination during walking turns in healthy individuals and asymptomatic individuals with a history of low back pain.
Methods
Participants performed multiple ipsilateral turns. Axial plane inter-segmental coordination and stride-to-stride coordination variability were quantified using the vector coding technique. …

Physical Therapy Faculty Articles and Research
Study Design
Cross sectional, laboratory study.
Background
Individuals with low back pain have impaired activation of multifidus during postural adjustments and increased activity of the erector spinae musculature during walking. However, it is unclear if these alterations in muscle activity are evident during locomotion in individuals with a history of low back pain when they are between symptomatic episodes.
Objectives
To compare paraspinal muscle activity in young healthy individuals and young individuals with a history of low back pain during walking turns.
Methods
14 asymptomatic individuals with a history of low back pain and 14 controls performed 90° walking turns …
