*FIM motor and transfer scores were Rasch-transformed.

**All patient and treatment variables listed in Tables 1 and 2 were allowed to enter the models except the injury being work related and time in PT activity of gait training due to insufficient representation in the group; additional variables allowed to enter model include Rasch-transformed admission transfer FIM score and the number of PT sessions focused on each type of transfer (to/from wheelchair, chair, mat, bed, vehicle, and floor); only statistically significant predictors are reported here; a missing variable name means that the variable did not predict any of the outcomes in this table; a blank cell means that the variable was not a significant predictor for the outcome examined.
