Hyperkinetic movement disorders (HMDs) can be assessed using
impairment-based scales or functional classifications.
The Burke-Fahn-Marsden
Dystonia Rating Scale-movement (BFM-M) evaluates dystonia impairment, but may not
reflect functional ability.
The Gross Motor Function Classification System
(GMFCS), Manual Ability Classification System (MACS), and Communication Function
Classification System (CFCS) are widely used in the literature on cerebral palsy
to classify functional ability, but not in childhood movement disorders. We
explore the concordance of these three functional scales in a large sample of
paediatric HMDs and the impact of dystonia severity on these scales. METHOD:
Children with HMDs (n=161; median age 10y 3mo, range 2y 6mo-21y) were assessed
using the BFM-M, GMFCS, MACS, and CFCS from 2007 to 2013. This cross-sectional
study contrasts the information provided by these scales. RESULTS: All four
scales were strongly associated (all Spearman's rank correlation coefficient rs
>0.72, p<0.001), with worse dystonia severity implying worse function. Secondary
dystonias had worse dystonia and less function than primary dystonias (p<0.001).
A longer proportion of life lived with dystonia is associated with more severe
dystonia (rs =0.42, p<0.001). INTERPRETATION: The BFM-M is strongly linked with
the GMFCS, MACS, and CFCS, irrespective of aetiology. Each scale offers
interrelated but complementary information and is applicable to all aetiologies.
Movement disorders including cerebral palsy can be effectively evaluated using
these scales.
