Reliability and validity of the Korean version of the manual ability classification system for children with cerebral palsy.
BACKGROUND
To investigate the inter- and intra-rater reliability of the Korean version of the Manual Ability Classification System (MACS) for children with cerebral palsy.


METHODS
After a two-step forward and one-step backward translation, the inter-rater reliability of the Korean version of the MACS was assessed separately by parents, occupational therapists and physicians. A second assessment for intra-rater reliability was performed 4 weeks later.


RESULTS
Sixty-nine children were enrolled. The intra-class correlation coefficients were 0.956 between occupational therapists and physicians, 0.927 between parents and physicians, and 0.960 between parents and occupational therapists. Intra-rater reliability ranged from 0.965 to 0.987.


CONCLUSIONS
The Korean version of the MACS is reliable and valid and is suitable for assessing manual ability in Korean children with cerebral palsy.
