Effect of different cognitive dual-tasks on postural sway and trunk stiffness in chronic low back pain patients compared to healthy controls.
Ulrike Van Daele, Sofie Lagrin, Ann Hallemans, Peter Vaes.
Purpose:
Low back pain patients often show larger postural sway compared to healthy control subjects, which indicate impairments in sensorimotor control. The purpose of this study is to investigate the effect of different cognitive dual tasks on sitting postural sway and trunk stiffness in chronic low back pain (CLBP) patients compared to healthy control subjects.
Relevance:
Cognitive dual-tasks are used to investigate the role of the cognitive systems and the amount of attention demand in postural control. Numerous types of dual-tasks are used to investigate the effect on postural control. The type of dual-task might influence the outcome.
Methods:
A total of 20 CLBP patients and 20 control subjects were included based on clinical criteria. The postural control tests were performed with and without cognitive dual-tasks. 3 different types (counting, memory and spatial memory) of cognitive tasks were utilized. A 3-dimensional motion analysis system was used to measure postural sway of trunk and pelvis in 3 cardinal planes. These data were used to evaluate motor control by means of postural sway and trunk stiffness.
Results:
The counting dual task had a significant different effect than the memory and spatial memory task within the control group. The counting dual task also had a significant different effect between both test groups. In the CLBP group the counting task leaded to increase in postural sway and increase in trunk stiffness. The control group showed decreased postural sway and decreased trunk stiffness.
Conclusion:
Different cognitive dual tasks lead to different effects on postural control within the control group. Depending on the type of dual task the effect is also different between CLBP patients and healthy controls.
Implications:
Interpretation of the influence of cognitive dual-tasks on postural control must be made carefully and situated under the specific conditions that were used.
