Article
Background: Although most research on spatial neglect (SN) has focused on spatial perception deficits with regard to the lateral (left-right) axis, deficits of spatial perception with regard to the vertical (up-down) axis, such as disturbances in the perception of verticality (e.g., judgement of vertical orientations), have also been suggested. O...

Objective The aim of this study is to determine the factors that affect patients’ ability to carry out high dose of massed practice. Methods Patients with stroke were included in the study if they had no severe impairment in motor and cognitive functions. Dose of massed practice, motor function, perceived amount and quality of use of the arm in th...

Previous studies already showed an association between visuospatial neglect (VSN) and worse functional balance and mobility after stroke. However, longitudinal studies that evaluate the behavior of this association over time are lacking, and it is generally unknown if functional motor milestones are re-acquired later in those with VSN compared to t...

Introduction: Although most stroke survivors show some spontaneous neurological recovery from motor impairments of the most-affected leg, the contribution of this leg to standing balance control remains often poor. Consequently, it is unclear how spontaneous processes of neurological recovery contributes to early improvements in standing balance....

Some subtypes of hemispatial neglect (HSN), such as visuo-spatial neglect, are negatively related with postural control. An impaired verticality perception is often hypothesized to be involved in these deficits. However, the association of HSN with verticality perception is not well-investigated. This study investigates the association between post...

The motor and functional consequences of personal neglect (PN) have not yet been systematically addressed, and whether the sole presence of PN or rather the co-occurrence of PN with another type of hemispatial neglect are related to similar consequences has not yet been investigated. Therefore, this systematic review evaluates the association betwe...

Question The outcome of recovery post-stroke is largely defined within the first 5-8 weeks suggesting that this is the optimal time to initiate rehabilitation. While robust findings on time-dependent therapy effects exist in animal models, clinical evidence is sparse due to a lack of early rehabilitation trials. We will discuss (1) the protocol and...

Introduction: Subjective tinnitus that is influenced by the somatosensory system is called somatosensory tinnitus (ST). When ST is related to the temporomandibular area, multidisciplinary orofacial treatment can reduce tinnitus severity. It is, however, unknown if we can predict this positive outcome. The aim of this study is to look for prognosti...

In healthy adults, four different muscle synergies have been described compared to three after stroke, as a result of merging of synergies. The presence of merged synergies was related to impaired motor function which makes muscle synergies a powerful tool for assessing neurological deficits.

Introduction Perception of verticality is highly related to balance control in human. Head-on-body tilt <60° results in the E-effect, meaning that a tilt of the perceived vertical is observed contralateral to the head tilt in the frontal plane. Furthermore, somatosensory loss also impacts the accuracy of verticality perception. However, when severa...
