Assisting Hand Assessment and Children's Hand-Use Experience Questionnaire –Observed Versus Perceived Bimanual Performance in Children with Unilateral Cerebral Palsy

Transcranial Direct Current Stimulation (tDCS) Paired with Occupation-Centered Bimanual Training in Children with Unilateral Cerebral Palsy: A Preliminary Study

“…The assessment tools selected for this study when taken together represent components of bimanual and unimanual hand function reporting both on the impairment and activity levels of the World Health Organization's International Classification of Functioning, Disability, and Health framework. The individual variability in gains observed between the assessment tools reflects differing constructs for each measure as reported by others [43].…”

To Explore the Validity of Change Scores of the Children's Hand-use Experience Questionnaire (CHEQ) in Children with Unilateral Cerebral Palsy

“…A different choice for an external anchor such as the ABILHAND-Kids (Arnould, Penta, Renders, & Thonnard, 2004), a parent-reported questionnaire of children's capacity to perform daily tasks, or the Assisting Hand Assessment (AHA), a standardized observational measurement of performance of the affected hand in bimanual activities (Krumlinde-Sundholm, Holmefur, Kottorp, & Eliasson, 2007), might have led to different conclusions. However, earlier investigations showed that AHA and CHEQ also only share some parts of their constructs (Ryll et al, 2017).…”

“…We hypothesized an effect size equal to or larger than 0.5 for participants that improved and an effect size smaller than 0.5 for participants that did not improve according to the GAS. Hypotheses about expected correlations between CHEQ scales and GAS were based on information about the relationship between the Assisting Hand Assessment and the CHEQ scales ranging from low to borderline high (Pearson's r = 0.28 to 0.50) (Ryll et al, 2017). Hypotheses of expected change in CHEQ scales were based on an intervention study Putting on socks () Carry a tray (e.g., in the canteen)…”

“…Therefore, a minimum of two scale steps of change in at least two out of three GAS goals was assumed to affect the construct of the CHEQ as nearly all GAS goals were directly or indirectly reflected by CHEQ activities (Table 1). Based on prior investigations of the relationship between perceived bimanual performance measured by CHEQ and the observed bimanual performance measured by the Assisting Hand Assessment (AHA) (Ryll, Bastiaenen, & Eliasson, 2017), positive relationships between the change scores of the CHEQ scales and the GAS as anchor were hypothesized to range from r = 0.3-0.5 for the CHEQ scale Grasp efficacy and Time utilization, as both have a common focus on bimanual activity performance. A slightly weaker association (r = 0.2-0.4) was expected for the CHEQ scale Feeling bothered, because we assumed the ability in specific task performance to be less related to feelings about this performance across tasks (Ryll et al, 2017).…”

Hand-Use-at-Home Questionnaire: validity and reliability in children with neonatal brachial plexus palsy or unilateral cerebral palsy

“…The CHEQ is a questionnaire for children (aged 6-18) with unilateral functional limitations of hand use and is well validated for children with unilateral cerebral palsy. 10,11,20 It was only partially validated for use in children with neonatal brachial plexus palsy 11 and has not yet been used in studies. Therefore, it was not used in this group.…”
