A study of nearly 2,000 adults who had inpatient surgery found that higher daily step counts after surgery were associated with fewer complications, fewer 30-day readmissions and shorter hospital stays. The observational study cannot show that walking caused those outcomes, and patients should ask their surgical team when it is safe to increase activity.
A study of nearly 2,000 adults who underwent inpatient surgery found that patients who took more daily steps after their procedure had a lower likelihood of complications and 30-day hospital readmission, along with shorter hospital stays. Published online May 6, 2026, in the Journal of the American College of Surgeons, the research found an association, not proof that walking caused better recovery.
Researchers analyzed data from a large National Institutes of Health research program. Participants had undergone various kinds of inpatient surgery and wore devices that tracked their steps for at least seven days before surgery and for several weeks afterward, on average. The analysis compared postoperative activity with each patient’s average daily step count before surgery.
For every additional 1,000 steps per day above that presurgical average, patients had a 17% lower chance of complications and a 15% lower likelihood of being readmitted to hospital within 30 days, according to the report. More postoperative walking was also linked to shorter hospital stays. The supplied report does not give the underlying event rates or specify how many days or weeks the step increases were sustained.
The study was observational, so it cannot establish that extra steps directly produced the improved outcomes. Patients who recover more readily may be able to walk more, and other differences between patients could also help explain the association. The report says the findings are consistent with other studies linking more walking after surgery with lower complication rates, but it does not provide details of those studies.
Step Counts and Recovery Outcomes
The findings add a measurable association between postoperative activity and outcomes that matter to patients and hospitals: complications, readmissions and time spent in hospital. Step counts may give care teams another way to follow a patient’s mobility after surgery and identify people who could need more support, according to the report.
For patients, the result is not a universal step target or a promise of faster recovery. The comparison was based on each person’s own presurgical average, and surgery type, overall health and complications can all affect how quickly someone resumes activity. Walking should be increased only when the surgical team says it is safe; the study does not establish a specific pace or schedule for doing so.

Why Hospitals Encourage Early Movement
Recovery varies with the type of surgery, a person’s overall health and whether complications occur. Medical centers commonly encourage patients to start walking when it is safe. The source report says early mobility can help prevent lung complications, blood clots and weakness, and may help reduce longer hospital stays.
The new analysis focuses on activity after surgery in relation to each patient’s presurgical step average. That framing differs from a single step goal for everyone: an additional 1,000 steps represents an increase relative to an individual baseline. The report attributes the summary to Lynne Christensen of Harvard Health and says she is a staff writer for Harvard Health Publications. Seniors Guide carried the report, distributed by Tribune Content Agency.
“The report says that “for every additional 1,000 steps patients made each day over their average presurgical step count,” researchers found a lower chance of complications and readmission.”

Limits of the Step-Count Findings
The study’s observational design leaves open whether more walking helps recovery, whether patients with fewer complications are simply able to walk more, or whether both are influenced by other factors. The reported percentages describe relative differences in likelihood; the source does not supply absolute complication or readmission rates that would show how many patients experienced these outcomes.
The available report also does not identify which operation types were included in detail, give separate results for different surgeries, or explain how step counts changed over the postoperative period. It does not set a recommended daily step target, specify when patients should increase walking, or show whether wearable tracking itself improves outcomes. The findings should not be read as a guarantee for an individual patient.
Guidance Depends on Each Operation
The next practical step for patients is to ask their surgeon or care team when and how to resume walking, particularly after a procedure with specific movement restrictions. The report says wearable devices can help patients track progress and help health care teams notice when additional support may be needed; it does not say that a device is required.
Further research would be needed to establish whether increasing steps directly changes recovery outcomes and to determine whether useful activity targets differ by surgery and patient. No such trial, target or follow-up milestone is specified in the supplied report. For now, the study offers evidence of a link between increased postoperative steps and better reported outcomes, while leaving causation and individual recommendations unresolved.
Key Questions
What did the study find about walking after surgery?
Among nearly 2,000 adults who had inpatient surgery, higher daily step counts after surgery were associated with fewer complications, fewer hospital readmissions within 30 days and shorter hospital stays.
What does the 1,000-step comparison mean?
The reported results compare each patient’s daily postoperative steps with that person’s average before surgery. For every additional 1,000 steps per day above that baseline, the study found a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days. These are reported relative differences, not absolute rates.
Does the study prove that walking prevents complications?
No. The research was observational and cannot show that walking caused the outcomes. Patients who are recovering better may be able to walk more, and other factors may affect both activity and recovery.
When should someone start walking more after surgery?
The report advises patients to ask their surgical team when it is safe to increase activity. The study does not set a step target or schedule, and safe movement can depend on the procedure and the patient’s condition.
