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. …

The Influence Of Hip Strength On Lower-Limb, Pelvis, And Trunk Kinematics And Coordination Patterns During Walking And Hopping In Healthy Women, Jo Armour Smith, John M. Popovich, Kornelia Kulig

Physical Therapy Faculty Articles and Research

Study Design

Cross-sectional laboratory study.

Objectives

To compare peak lower-limb, pelvis, and trunk kinematics and interjoint and intersegmental coordination in women with strong and weak hip muscle performance.

Background

Persons with lower extremity musculoskeletal disorders often demonstrate a combination of weak hip musculature and altered kinematics during weight-bearing dynamic tasks. However, the association between hip strength and kinematics independent of pathology or pain is unclear.

Methods

Peak hip extensor and abductor torques were measured in 150 healthy young women. Of these, 10 fit the criteria for the strong group and 9 for the weak group, representing those with the strongest …
