This is a prospective observational study looking at gait-cadence in older adults who are scheduled to have major abdominal surgery at the University of Chicago. The objective of the study is to evaluate whether gait-cadence, as measured from a patient's mobile device at-home, can provide an accurate assessment of a patient's functional status prior to major abdominal surgery and identify patients at risk of poor functional outcomes.
Over 100,000 older adults undergo elective major abdominal surgeries in the US each year and many experience loss of mobility after surgery that requires post-acute care. Risk of mobility loss is greater for older adults unable to engage in moderate-intensity physical activity before surgery. Additionally, recovery trajectories to baseline mobility remains poorly understood for older adults and may impact readmission. Functional status assessment before surgery can identify interventions to help older adults improve walking capacity and improve recovery trajectories after surgery. However, alm…
Inclusion Criteria: * Patients \> or = 60 years of age and scheduled for surgery. * Access to a safe walking space roughly 30 ft in length. Safe walking spaces include a long hallway in the home, common use hallway in an apartment building or outside public area. * Able to walk independently with or without an assistive device (e.g. cane or walker) Exclusion Criteria: * Inability to walk independently * Surgery scheduled less than 7-days after APMC appointment * Patients scheduled for orthopedic surgery * Patients scheduled for neurological surgery * Patients scheduled for cardiac surgery *…
Patients who are scheduled to have surgery at University of Chicago Medical Center (UCMC) who agree to use the step test application and study accelerometer before and after their surgery.
