Variables included in the multivariable models: FIM locomotion score at admission to rehabilitation, modified RAND comorbidity score, age, sex, type of surgery (hip fracture repair, hip replacement, knee replacement), race/ethnicity, and GDS score

Sample size on day 7 was 168 (64 control and 104 intervention patients) due to discharges
