Williams et al modified the BODE score to use incremental shuttle walking test (ISWT). The authors are from the University of Leicester NHS Trust and Coventry University in the United Kingdom.
Patient selection: COPD
Parameters:
(1) FEV1 as percent of predicted
(2) meters walked in the incremental shuttle walk test (ISWT)
(3) dyspnea, measured using the MRC dyspnea scale, from 1 to 5 (Fletcher Scale)
(4) body mass index in kg per square meter
