Study Design. A cross-sectional study to quantify trunk motor control during multidirectional isometric tracking tasksObjective. To investigate the effect of @entity1643 (LBP) on trunk neuromuscular performance while @entity1 performed isometric exertions of trunk muscles to track targets in different angles with various magnitudesSummary of Background Data. Tracking tasks especially in multidirectional activities are among the common research methods to quantify @entity1 motor control in different conditions. However, little information is available on trunk motor control during these tasks. There is no study investigated trunk accuracy during multidirectional isometric tracking tasks in @entity1 with LBP.Materials and Methods. Twelve @entity1 with chronic LBP and 16 asymptomatic @entity1 performed isometric target tracking tasks in 12 different directions with varying magnitude, from 0 to 80% of individual @entity2798 ( @entity2798 ), in upright standing posture. The tracking system included a moving target object which moved on a straight line in a predefined angle with the rate of 6% @entity2798 /s. Trunk accuracy was quantified by computing constant error and variable error during each trial. A mixed model repeated measure analysis of variance was conducted to assess statistical analysis.Results. @entity1 with chronic LBP track the target object with higher error compared to healthy controls across almost all of the target angles (P <0.01). Trunk accuracy decreased significantly in higher level of exertions (P <0.01).Conclusion. The results provided additional evidence of a change in trunk control strategies in @entity1 with chronic LBP. Decreased accuracy of trunk during isometric tracking tasks especially in higher levels of asymmetric exertions may explain higher risk of @entity13400 in these activities.
