1Department of Rehabilitation, Incheon St. Mary's Hospital, The Catholic University of Korea, Incheon, Korea.
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.
