Background: Limited research exists regarding the effectiveness of electroencephalogram (EEG) neurofeedback training for children with cerebral palsy (CP) and co-occurring attention deficits (ADs), despite the increasing prevalence of these dual conditions. This study aimed to fill this gap by examining the impact of neurofeedback training on the attention levels of children with CP and AD.

Methods: Nineteen children with both CP and co-occurring ADs were randomly assigned to either a neurofeedback or control group.

Background: Neural gating of respiratory sensations (NGRS) characterises the brain's ability to filter out repetitive respiratory sensory stimuli. This mechanism plays a crucial role in the neural processing of respiratory stimuli. However, whether ageing affects NGRS in healthy adults is still unclear.

Individuals with generalized anxiety disorder (GAD) have been shown to have altered neural gating of respiratory sensations (NGRS) using respiratory-related evoked potentials (RREP); however, corresponding neural oscillatory activities remain unexplored. The present study aimed to investigate altered NGRS in individuals with GAD using both time and time-frequency analysis. Nineteen individuals with GAD and 28 healthy controls were recruited.

Background: Human respiratory sensory gating is a neural process associated with inhibiting the cortical processing of repetitive respiratory mechanical stimuli. While this gating is typically examined in the time domain, the neural oscillatory dynamics, which could offer supplementary insights into respiratory sensory gating, remain unknown. The purpose of the present study was to investigate central neural gating of respiratory sensation using both time- and frequency-domain analyses.

Importance: Impaired tactile perception frequently accompanies motor deficits in children with cerebral palsy (CP). Assessing tactile perception precisely for children with CP remains challenging because of a lack of assessments with robust psychometric evidence or standard procedures.

Objective: To develop a standardized assessment tool, the Tactile Perceptual Test (TPT), for measuring tactile perception in children with CP and to examine its psychometric properties.

Importance: Emerging research has demonstrated that constraint-induced movement therapy (CIMT) and bimanual intensive training (BIT) show promising effectiveness for children with unilateral cerebral palsy (UCP). Considering that neurorehabilitative programs have always been designed with long training periods, psychosocial outcomes have received scarce attention and thus have not been investigated sufficiently.

Objective: To compare the efficacy of CIMT and BIT with 36-hr interventional dosages for both motor and psychosocial outcomes.

Background: Previous studies have compared the effectiveness of constraint-induced movement therapy (CIMT) by different training doses. However, whether the dosing schedule, that is, intensive or distributed, influences the effectiveness of CIMT in children with unilateral cerebral palsy (CP) is unknown.

Objective: To investigate the effectiveness of intensive and distributed CIMT for children with unilateral CP.

This study aimed to examine the reliabilities (test-retest reliability and measurement error), construct validity, and the interpretability (minimal clinically important difference) of the Box and Block Test (BBT) to interpret test scores precisely for children with UCP. A total of 100 children with UCP were recruited and 50 children from the whole sample assessed the BBT twice within 2-week interval. The BBT, the Melbourne Assessment 2, the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition, and the Pediatric Motor Activity Log Revised were measured before and immediately after a 36-h intensive neurorehabilitation intervention.

Background: Motor impairments in children with cerebral palsy significantly reduce their ability to learn and adapt bimanual actions into their life roles. The current evidence on bimanual coordination performance in children with hemiplegic cerebral palsy were mostly drawn from kinematic studies. Whether these kinematic findings on bimanual motor performance can be observed when performing daily life activities in a natural environment is not clear.

Importance: Children with hemiplegic cerebral palsy (CP) demonstrate spatial attention disregard, but the rehabilitation approach to CP is traditionally motor oriented.

Objective: To explore spatial attention disregard in children with hemiplegic CP and its relationship to their motor performance in daily activities.

Design: Cross-sectional study.

Article Synopsis
  • The study evaluates the psychometric and clinimetric properties of the Melbourne Assessment 2 (MA2) as an outcome measurement in children with cerebral palsy (CP).
  • Seventeen children participated to assess test-retest reliability and minimal detectable change (MDC), while thirty-five children underwent an 8-week rehabilitation program to determine validity and responsiveness.
  • Results showed that the MA2 demonstrated high reliability, significant relationships with other motor proficiency tests, and established benchmarks for clinically important differences (MCID), confirming its effectiveness as a measurement tool.
