Abstract

Control and movement characteristics of reaching performance are complex and challenging to understand in stroke rehabilitation. There are many kinematic variables to quantify different aspects of reaching performance. The purposes of this study were to explore the measure constructs of kinematic measures in reaching performance and to investigate the relationships between kinematic measures in reaching and clinical motor evaluation. This study recruited 40 patients after stroke and measured the subjects' paretic arm reaching performance with kinematic analysis. Findings in this study showed that variables of kinematic measures for reaching performance could be reduced to two principal conceptual measure constructs. One measure construct relates to movement speed and smoothness. The other measure construct might relate to movement strategy (feed forward or feedback control). Motor impairments scores showed significant correlations with movement speed and movement smoothness variables. This study suggests that a comprehensive kinematic measure of reaching performance should include the variables to reflect the characteristics of movement speed, movement smoothness and movement strategy.
