Comparison of the reticulospinal drive to lumbar erector spinae muscles in postural and voluntary tasks using the StartReact paradigm

The StartReact paradigm remains one of the few techniques available in humans to evaluate the reticulospinal drive in different tasks and/or muscles. Recent studies have highlighted the usefulness of ...

Reticulospinal modulation of muscle activation and electromechanical coupling: evidence from the StartReact paradigm

The StartReact paradigm was implemented in 29 healthy participants performing 14 single-joint motor tasks including both upper and lower extremities. Muscle activity was recorded using surface ...

StartReact effects in first dorsal interosseous muscle are absent in a pinch task, but present when combined with elbow flexion.

To provide a neurophysiological tool for assessing sensorimotor pathways, which may differ for those involving distal muscles in simple tasks from those involving distal muscles in a kinetic chain ...

StartReact restores reaction time in HSP: evidence for subcortical release of a motor program.

Startling acoustic stimuli (SAS) can accelerate reaction times ("StartReact" effect), but the underlying mechanism remains unclear. Both direct release of a subcortically stored motor program and a ...
