“…Easy to use scales have been developed to describe the gross motor performance (Palisano et al, 1997) and manual performance (Beckung & Hagberg, 2002;Eliasson et al, 2006) of children with cerebral palsy and are now used across surveillance registers rather than detailed clinical assessments such as the Gross Motor Function Measure (Russell et al, 1993) or the ABILHAND-Kids (Arnould, Penta, Renders, & Thonnard, 2004).
