Note: RISE = Rehabilitative Impairment Study of the Elderly; ROM = range of motion; SPPB = Short Physical Performance Battery.
aAll models were adjusted for age, race, gender, Katz comorbidity score, body mass index, Patient Health Questionnaire-9 score (depression), Digit Symbol Substitution Test, and other neuromuscular attributes.
