At-home Walking Cadence Functional Assessment and Recovery Trajectory for Older Adults Undergoing Major Surgery
(CADENCE)
What this study is about
This is a forward-looking observational study looking at gait-cadence in older adults who are scheduled to have major abdominal surgery at the University of Chicago.
View original scientific description
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.
Interventions
OTHER
Patients using Step Test Application and Accelerometer
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.
Primary outcome measures
Accuracy of gait-cadence measured from at-home and in-clinic walk tests as measured by ActivPAL accelerometers.
Time frame: Baseline (Before surgery)
ActivPAL accelerometer will be worn during in-clinic walk tests to serve as reference of steps walked during the at-home walk tests.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
