The place of manual ability according to the ICF classification
Manual ability, as measured by ABILHAND and ABILHAND-Kids, is defined as the capacity to manage daily activities that require the use of the upper limbs, whatever the strategies involved (Penta et al. 1998, 2001, Arnould et al. 2004). It refers to the Activity domain of the ICF.
See the page on the International Classification of Functioning, Disability and Health.
Development of the ABILHAND-Kids scale using the Rasch measurement model
The ABILHAND-Kids questionnaire assesses manual ability as a test focused on the child's difficulty perceived by the child's parents.
The questionnaire was developed using the Rasch measurement model which provides a method to convert the raw scores into a linear measure located on a unidimensional scale.
ABILHAND-Kids has been calibrated in children with cerebral palsy (Arnould et al. 2004) according to the difficulty of children in performing manual activities as perceived by their parents.
Originally developed in French, ABILHAND-Kids has been translated into various languages. ABILHAND-Kids specific to cerebral palsy children is currently available in French, English and Dutch. See the downloads section.
ABILHAND-Kids in cerebral palsy children
- 21 manual activities perceived by the children parents.
- Each item is answered on a 3-level scale (impossible, difficult, easy).
- The item difficulty increases with bimanual involvement.
- Measurement range: approx. 9 logits.
- Measurement error: 0.42 logits in the centre of the scale.
- Least measurable difference: 0.19 logit in the centre of the scale.
- Separation reliability: 0.94 in our sample of 113 children with cerebral palsy.
- Invariant item hierarchy across: gender, age, handedness, type of education, type of cerebral palsy (tetra-, di-, or hemi-plegia), side affected, overall ability in our sample of 113 children with cerebral palsy.
- Test-retest reliability: R=0.91 after a delay of (25 +/- 13) days.
