Quantitative electrophysiological assessments as predictive markers of lower limb motor recovery after spinal cord injury: a pilot study with an adaptive trial design   The goal of this study is to determine the feasibility and relevance of assessing corticospinal, sensory, and spinal pathways early after traumatic spinal cord injury

Delayed and reduced intralimb muscular coupling during postural reactions in individuals with incomplete spinal cord injury Postural strategies are enabled by rapid muscle activation sequences to prevent a fall. Intralimb muscular couplings underlie these postural strategies are likely impaired after incomplete spinal cord injury (iSCI), leading to inappropriate postural

Assessing head acceleration to identify a motor threshold to galvanic vestibular stimulation Galvanic vestibular stimulation (GVS) is used to assess the vestibular system, but the high interindividual variability in responses makes comparison between individuals or between different conditions difficult. By using an accelerometer to quantify SVG-induced head movement, we

Interhemispheric interactions between trunk muscle representations of the primary motor cortex   The mechanisms involved in the bilateral coordination of axial muscles of the trunk during unilateral arm movement are poorly understood. We thus investigated the nature of interhemispheric (between the two hemispheres of the brain) interactions in axial

H-reflex modulation preceding changes in soleus EMG activity during balance perturbation When balance is compromised, postural strategies are induced to quickly recover from the perturbation and to regain balance. However, neuronal mechanisms underlying these strategies are not fully understood. In this article, we assessed the amplitude of the Hoffmann’s

Alteration of H-reflex modulation underlies impaired postural responses in individuals with incomplete spinal cord injury Individuals with incomplete spinal cord injury (iSCI) are at higher risk of falling, even after intensive functional rehabilitation (Brotherton et al., 2007; Amatachaya et al., 2011). This risk of falling is due to decreased

Assessment of vestibulocortical interactions during standing in healthy subjects The vestibular system is essential to produce adequate postural responses enabling voluntary movement. However, it is still unknown how exactly the vestibular system influences corticospinal output during postural tasks. Here, we examined the modulation exerted by the vestibular system on
