Feasibility Study of Post-hospitalization Interventions to Improve Physical Function in Older Adults

The purpose of this study is to test the feasibility of interventions to accelerate recovery
of muscle mass and function in older adults following acute hospitalization

Inclusion Criteria:

infection, or metabolic disorder; or other condition that will allow a subject to
participate in the study after patient review

- Aged 65 years or older

- Self-reported ability (with or without the aid of an assistive device) to walk across
a small room two weeks prior to hospitalization

- Lives within 30 miles of UTMB

- Can stand without assistance at the time of pretesting

- Presents no medical contraindication to wearing a loose fitting velcro strap for the
accelerometer on one ankle

physician on H&P

- Is discharged "to home" at ACE unit discharge.

Exclusion Criteria:

- Nursing home resident or hospice patient

- Glomerular filtration rate (GFR) <30 mL/min/1.73m2 or evidence of kidney disease or
failure

- Liver disease ( aspartate aminotransferase (AST) /Alanine transaminase (ALT) 2 times
above the normal limit, hyperbilirubinemia)
