StartReact increases the probability of muscle activity and distance in severe/moderate stroke survivors during two-dimensional reaching task

Abstract StartReact elicits faster, larger, and more appropriate muscle activation in stroke survivors but has been only cursorily studied to date during multi-jointed reaching. Our objective was to evaluate StartReact on unrestricted, two-dimensional point-to-point reaching tasks post-stroke. Data from 23 individuals with stroke were collected during point-to-point reaching. Voluntary and StartReact trials were compared between mild, severe/moderate, and the unimpaired arm. StartReact...

Muscle synergy for upper limb damping behavior during object transport while walking in healthy young individuals

Abstract Transporting an object during locomotion is one of the most common activities humans perform. Previous studies have shown that continuous and predictive control of grip force, along with the inertial load force of the object, is required to complete this task successfully. Another possible CNS strategy to ensure the dynamic stability of the upper limb is to modify the apparent stiffness and damping via altered muscle activation patterns. In this study, the term damping...

Motor and spatial representations of action: corticospinal excitability in M1 after training with a bimanual skill

Abstract The purpose of the study was twofold: (1) determine if different time delays (30 min or 6 h) between training and a post-training test with a rhythmic bimanual pattern (90° relative phase) would be associated with different levels of consolidation for the motor and spatial representations of the pattern; and (2) determine if training with the rhythmic bimanual pattern would lead to enhanced corticospinal excitability in M1 linked to changes in motor and spatial performance...
