Table 4.
Reliability and agreement of Sunnybrook system parameters across assessment modes. No percentage close agreement (PCA) was calculated for the weighted total resting symmetry and weighted total voluntary movement scores because raw scores were multiplied by 5 and 4 respectively to determine the weighted total scores; there would not be cases where scores differed by only 1 point. No PEA and PCAs were calculated for the composite score, which was derived from a formula in which resting symmetry, voluntary movement, and synkinesis were weighted differently.
