Metric properties of the ASIA motor score: Subscales improve correlation with functional activities¹

Boxplots of discharge ASIA motor scores and motor FIM scores. Legend: bars indicate median; boxes represent 25% to 75% range; lines indicate outliers. Abbreviations: FIMTOT, total motor FIM score; FIM_LO, FIM lower cord score; FIM_UP, FIM upper cord score; MS_TOT, total ASIA motor score.

Boxplots of discharge ASIA motor ability and motor FIM ability estimates. Ability is the mean likelihood estimate of ability. Legend: bars indicate median; boxes represent 25% to 75% range; lines indicate outliers; squares indicate range of extreme outliers. Abbreviations: FIM_LAE, FIM lower cord ability estimate; FIM_TAE, total motor FIM ability estimate; FIM_UAE, FIM upper cord ability estimate; MAE_TOT, total ASIA motor ability estimate.

ASIA motor score information function. Legend: bars indicate range of ability estimates with desired levels of information: the striped bar represents total ASIA motor score values, the solid gray bar represents subscore values. Use of subscores increased the information at the lower levels of ability. Abbreviations: LEAE, lower-extremity ability estimate; MAE_TOT, total motor ability estimate; UEAE, upper-extremity ability estimate.

Motor FIM information function. Legend: bars indicate range of ability estimates with desired levels of information: the striped bar represents total motor FIM ability estimate values, the solid gray bar represents subscore values. Use of subscores did not appreciably increase information.
