Background and Purpose—The active force generated by a single muscle fiber is greatest in
midrange. In healthy subjects, the reduced muscle force at short muscle length is partially …

Contraction of a muscle modulates not only the corticospinal excitability (CSE) of the
contracting muscle but also that of different muscles. We investigated to what extent the CSE …

This study investigates whether spinal manipulation leads to changes in motor control by
measuring the recruitment pattern of motor units in both an upper and lower limb muscle and …

Lengthening and shortening contractions are the fundamental patterns of muscle activation
underlying various movements. It is still unknown whether or not there is a muscle-specific …

Background. Individuals with incomplete spinal cord injury (SCI) are predisposed to muscle
fatigue during voluntary exercise. However, the origin of fatigue is unclear. Objective. The …

The concept of synergies has been used to address the grouping of motor elements
contributing to a task with the covariation of these elements reflecting task stability. This …

Motor impairment after stroke is generally caused by damage to the neural networks that
control movement. Corticomuscular coherence (CMC) is a valid method to analyze the …

New Findings What is the central question of this study? Progressive development of the
supraspinal component of central fatigue and increases in corticospinal excitability and …

Spinal networks in the cervical and lumbar cord are actively coupled during locomotion to
coordinate arm and leg activity. The goals of this project were to investigate the …

In this study, we examined the effect of muscle fatigue induced by tetanic electrical
stimulation (ES) and submaximal isometric contraction on corticomotor excitability …
